FOMS Menu 220 (Aircraft Characteristics Program)

Note: The following descriptions represent the typical access and privileges afforded to users designated as Dispatch Managers/Supervisors. Users with dispatcher privileges will have limited access to a subset of the screens presented.

The Aircraft Characteristics menu has a corresponding web interface. See WebFOMS Aircraft Characteristics Menu for more information.

This data file is for the storage of information on each aircraft in the airline’s fleet. An aircraft record must be entered in the file before a flight can be run using that aircraft. Given no more than the airline’s identification number (or letters) for a particular aircraft (sometimes referred to as FIN, tail, wheel, hull or airframe number), other programs in the system can access this data file and obtain information such as aircraft type, operating weights, SELCAL code, and fuel consumption deviations.

When the program is selected, the screen will be filled with a blank record and Command Line.

The modes available are:

  • Add

  • Edit

  • Delete

  • Video

  • Screen

  • Hardcopy

  • Quit

Add Mode

ID: The key parameter in the Aircraft Characteristics data file is this aircraft identification number. This can be any combination of three or four numbers or letters. In all modes except Add, you may use the aircraft registration to call up the required aircraft record.

Type: Enter the aircraft type (e.g., A320).

Series: Enter the series designation of the aircraft (e.g., 30) or ? to scroll through options

Engines: Enter the type of engine installed on the aircraft (e.g., CF6-50E2). Or ? to scroll through options

Unt: Enter the type of units of weight that this particular aircraft is calibrated in, lbs <L> or kgs <K>.

Reg: Enter the complete International registration for the aircraft (e.g., N123AB).

CC: Enter the Country Code for this Aircraft (this will override the ALC Domestic CC so only fill out if it differs from the standard).

ALC: The standard airline code for your airline. If you have a Multi-ALC and want to use the aircraft for different ALCs, leave this blank. 

FMT: Enter the default format number for the flight plan for both Domestic and International flights. This may be left blank, in which case the system will default to the format specified in the Airline Code Parameter file. This field is intended to allow you to specify a format for those aircraft that are non-standard.

Reserve: Enter the domestic and international reserve code policy numbers, or use the <?> search function. If you use the search function, the policy is displayed in the lower left corner of the screen. Use the up and down arrows to scroll through the options, and press <Enter> to select. These reserve policies will be loaded as default when the FIN for the aircraft is entered in the Plan screen. The user can change the defaults from the Plan screen.

Expires: This field indicates when an aircraft is to expire. A report can be generated indicating what aircraft is about to expire and when. This field is optional. 

Profile: Enter the default performance profile for this aircraft (e.g., LRC, HSC, or M78), or use the <?> search function. If you use the search function, the policy is displayed in the lower left corner of the screen. Use the up and down arrows to scroll through the options, and press <Enter> to select.

Opt CI: Indicate whether to use OPT CI in the flight plan: yes <Y> or no <N>.

Min/Max Opt CI: Enter the minimum and maximum to control the optimum cost index. The optimum cost index will not fall outside of this range.

CI Adjust: This field is intended for specific use for A330 planning when using Opt CI. It compensates for optimum cost index results vs FMS entry. Valid entries are between -999 and 999. Entering -999 will select CI000 and entering 999 will select CI999 (if available). If they are not available, the closest CI value will be chosen.

Climb Bias: Enter the deviation from base-line climb performance data. 1.000 represents nominal performance. If the aircraft burns more than standard, then enter a value greater than 1, e.g., if an aircraft is burning 5% more than standard book values, enter 1.05. The limits are -10% to +25%, i.e., 0.900 to 1.250.

Additional Climb Bias: Enter any additional climb bias. The limits are -10% to +25%. The field does not accept negative numbers and the Climb plus Additional bias cannot exceed a total of -10% to +25%.

Climb Time Bias: Enter any fixed amounts of time by which you wish to bias the climb performance data.

Climb Fuel Bias: Enter any fixed amounts of fuel by which you wish to bias the climb performance data.

Cruise Bias: Enter the deviation from baseline cruise performance data. 1.000 represents nominal performance. If the aircraft burns more than standard, enter a value greater than 1, e.g., if an aircraft is burning 5% more than standard book values, enter 1.05. The limits are -10% to +25%.

Additional Descent Bias: Enter any additional descent bias. The limits are -10% to +25%. The field does not accept negative numbers and the Climb plus Additional bias cannot exceed a total of -10% to +25%.

Descent Time Bias: Enter any fixed amounts of time by which you wish to bias the descent performance data.

Descent Fuel Bias: Enter any fixed amounts of fuel by which you wish to bias the descent performance data.

Min Desc: Enter the minimum descent fuel amount.

Hold Bias: Enter the deviation from baseline hold performance data. 1.000 represents nominal performance. If the aircraft burns more than standard, enter a value greater than 1, e.g., if an aircraft is burning 5% more than standard book values, enter 1.05. The limits are -10% to +25%.

Additional Hold Bias: Enter any additional hold bias. The limits are -10% to +25%. The field does not accept negative numbers and the Climb plus Additional bias cannot exceed a total of -10% to +25%.

Additional Alt Bias: Enter any additional alternate bias. The limits are -10% to +25%. The field does not accept negative numbers and the Climb plus Additional bias cannot exceed a total of -10% to +25%.

Alt Time Bias: Enter any fixed amounts of time by which you wish to bias the alternate performance data (climb only)

Alt Fuel Bias: Enter any fixed amounts of fuel by which you wish to bias the alternate performance data (climb only).

Alt Min: Enter Minimum Alternate burn (mandatory field)

Idle / PF: Enter an idle factor value and performance factor, this value can be displayed on the Flight Plan, but has no effect on the calculation.

RAMP: Enter the maximum allowable weight of the aircraft prior to taxi.

MTOW: Enter the maximum take-off weight to that this aircraft has been certified for flight.

Variable MTOW MIN/MAX: Optional field. Some aircraft allow the typical maximum take-off weight to be exceeded in order to allow for a larger payload. As the MTOW is increased, the zero-fuel weight (ZFW) decreases in a linear fashion, thus fuel may be sacrificed for payload to an acceptable point. Enter the minimum and maximum variable take-off weight values to calculate a variable MTOW.

MZFW: Enter the maximum zero-fuel weight for which this aircraft has been certified for flight.

Variable ZFW MIN/MAX: Some aircraft allow the typical zero fuel weight to be exceeded in order to allow for a larger payload. As the ZFW is increased, the maximum take-off weight (MTOW) decreases in a linear fashion, thus fuel may be sacrificed for payload to an acceptable point. Enter the minimum and maximum variable zero-fuel weights to calculate a variable ZFW.

Min ZFW: Enter the minimum zero fuel weight.

Note: If the calculated zero fuel weight is below the MIN ZFW then BALLAST fuel will be automatically added. Typically, this is a parameter to enable, where by default ballast is not part of ZFW. Be mindful that the ballast could reduce your max payload if limited by MZFW. The system displays a warning message if ballast fuel was added to meet MIN ZFW.

MaxFuel Wgt: Enter the maximum weight of fuel that may be boarded with all tanks full.

Vol / Max Fuel Volume: Enter the maximum fuel volume, the value will be converted based on the fuel density of departure airport and will be used as the maximum fuel tank limit. Max fuel uplift weight is ignored if the volume amount is specified.

Unit: Enter max fuel volume unit (USG, LIT, UKG)

Min Flt Wgt: Enter the minimum flight weight to automatically add to ballast fuel.

Min Disp: Enter the minimum amount of fuel that must be on the aircraft for it to be flown, according to your Company policy. There is no point in making this less than Min Landing Fuel.

Reclear Pad: Enter the default value for Planned Redispatch Fuel Padding.

Spare Tank: This field only applies when using the Max, OPT, or Table tankering options. Enter a weight value to reduce tankerage and leave room for last minute payload addition. The system will calculate the desired tankerage and then subtract the Spare Tank amount. In the example below, you can see a difference in the XTR field (244215lb in the flight plan with Max Spare set to 10000lb vs 254215lb in the flight plan with Max Spare set to 0)

Please Note: The Spare Tank function takes into account the payload available before reaching MZFW, and will decrease the buffer where restricting the uplift would not be beneficial. (e.g. 10000lb Spare Tank set and no MTOW constraints, but only 3000lb payload available before reaching MZFW. The system will decrease the Spare Tank value to 3000lb and upload 7000lb of fuel instead).

Ballast: Enter the amount of standard ballast fuel. This value will populate the corresponding field in the Fuel Group (Plan screen of the NFP UI).

Spare: Enter the weight of the spares.

Dom/Intl Hold Fuel/Time:  These entries enable the user to control exactly how the hold fuel is to be calculated and whether or not hold performance data is available. If hold performance is available (and part of the selected Performance Profile Key), then these fields may be used to define minimum values for holding fuel. In most cases, however, if holding performance data is available, then these fields may be left blank. In the event that entries are made, they will be interpreted by the flight plan in accordance with the following table:

In the case where the hold time value has been entered as 0, the hold time will be calculated using the following parameters:

ISA = 0

Weight = EZFW + Min Landing Fuel

Elevation = Alternate airport elevation + 1500feet (If alternate = NONE, use destination airport elevation.)

No Alt: If there is no Alternate selected on the flight plan, then use this burn for XX lbs/kgs

  • Select where this fuel should be displayed: (A)lt/(H)old)A(D)ditional

Timecalc: identifies how time conversion is completed, options include: H - Using the hold fuel burn rate, T - Using the top of descent fuel flow or C - Use custom rate as defined in the next field.

If you set the Timecalc field to Custom you must enter a time in minutes along with a fuel value in the Custom field below - based on an hourly rate. The resulting MLF value is based on the time and fuel value entered. This is the same behavior as taxi time/fuel.

Min Cruise Dist: Enter a minimum cruise distance. The default value is 0 (zero). If non-zero, the flight plan may not climb as high to result in a longer cruise distance. The system may prefer lower flight levels if cruise distance of the flight does not adhere to the minimum cruise distance. This will not guarantee that the minimum distance will be satisfied because of minimum flight level restrictions.

RoundUp Fuel: This will round up the ramp fuel to an even number (100s)

Taxi: Enter the taxi fuel burn rate in units per hour.

Taxi Fuel Rate: Enter the taxi fuel rate: fixed <F> or per hour (blank).

Advisory Fuel: Enter the amount of advisory fuel

    If a value is entered, the next field will ask if the fuel is Optional

Advisory Reason: Enter an advisory fuel reason, can be a combination of letters and numbers and is unique to your airline. 

Max FL: This field is used to set the maximum flight level the aircraft is capable of operating at. Most often it is set to the certified limit of the aircraft; if it is left blank the system will flight plan based on all available performance data, which in some cases could exceed service ceilings.

Receiver Type (RAIM/ADSB): The ADSB check and RAIM calculation supports GPS specifications TCO C-129a, TCO C-145a, TCO C-146a and TCO C-196a  receivers. The GPS receiver in the aircraft will be compliant with one or more of these specifications. The receiver type must be set in Aircraft Characteristics or else a compute error will be generated.

Baro. Aiding: The GPS receiver in the aircraft may have a physical connection to the Baro-altimeter or the FMS. If it does, select this checkbox. If you do not know if the GPS receiver is “baro-aided”, then the safe option would be to keep this checkbox de-selected (No).

FDE Algorithm: Options are Yes, No or E (enroute only) The service supports both FD (Fault Detection) and FDE (Fault Detection and Exclusion) RAIM algorithms. Some airspaces, routes, or approaches may mandate that FDE be used for the RAIM prediction. Selecting TCO-C145a or TCO-C146a receivers will automatically set the algorithm to FDE. If you do not know which algorithm the GPS receiver is using, NAVBLUE recommends that you keep this checkbox de-selected. When set to E (enroute only), the FDE Algorithm is used only for the enroute portion of the flight.

SA Status: Selective Availability - Most modern GPS receivers will be set to use SA OFF. In some cases the GPS receiver manufacturer will the receiver is SA aware. This means the GPS receiver will use the SA status of the GPS constellation - SA OFF. If SA Status is not specified the system assumes the setting is SA ON.

RNP AR Check: If checked, an RNP AR check is performed provided that the aircraft is configured for checks and the airport data has been entered for landing airports only in a new Airport Configuration WebFOMS screen. The check occurs during RAIM validation. This requires a configuration change, contact support for more details.

SBAS Status: This turns on the Satellite-Based Augmentation System receive. Selecting this check box prompts the equipment to lead to an automatic result of "No Check Required".

OEW: Enter the dry empty weight of the aircraft. Eighteen different values may be entered to reflect up to nine different configurations of the aircraft that can be selected in the flight plan screen. In order to support up to nine values and still maintain one screen; paging functionality is added to the OEW field. This means that once a user has entered his third value and selects enter the OEW field will go blank and the cursor will be placed in the first blank field of the OEW section. The first three weights have been saved to the record at this point. Now either the user may enter additional OEW weights or he may select enter. If the user wishes to input additional weights, he can do so at this point. After the next three weights are entered and the user selects enter, the fields will again be blanked out indicating that the weights have been written to the record. Again, the user may now enter additional weights or select enter. Selecting enter will move the cursor to the MZFW field and the original three OEW weights will be displayed. Only one entry is mandatory.

CODE: Enter the operating empty weight code.

INDEX: Enter the operating empty weight index (usually for CG).

CREW: In the first field, enter the number of flight deck crew members. In the second field, enter the number of cabin crew members.

Req Rwy Surface: Enter the required runway surface. Enter <H> for hard, <S> for soft, <W> for water or <U> for undefined. This is used to improve filtering for suitable escape routes for airports.

Default Runway: Enter  a  default runway to be used in the Route Builder screen when a specific aircraft is used. Options are <L> Longest Procedure, <M> Max Head Wind <B> Best Route or <N> None.

RTE QUAL: This field is used to allow the user to specify what equipment is on board the aircraft. The route analysis process will read the data in this field and verify that there is a match before using a particular route in the analysis process. See section 305 for information regarding this field in the route building process. The valid entries are any text character. The field was designed to allow the user to define their own special equipment codes, thus the reason for allowing any text character to be entered. Maximum number of entries is 4 per aircraft.

Atc Alias: Add this alias to the default ATC addresses.

Fp Alias: Add this alias to the default flight package addresses.

Talt Max Dist: This field specifies the maximum distance a takeoff alternate may be from the origin airport in the flight planning process. User may specify the distance or leave the field blank. In either cased if a takeoff alternate is used in the flight planning process for the specified aircraft and the distance to that alternate is in excess of the value contained in the field the user will receive an error message indicating the problem. See the flight plan section of the manual for specifics. If the field is left blank then the takeoff alternate distance will default to 500 nautical miles for a two-engine aircraft and 1000 miles for three- and four-engine aircraft.

Approach Spd Cat: Enter the approach speed category - A, B, C, D, E, or blank).

Iata Config Code: IATA Configuration Code

Max Climb Grad: enter maximum climb gradient (0.1% - 20%)

ACN Min/Max: Enter the ACN minimum and maximum weights. Typically, the minimum would be the same as the operating empty weight, and the maximum would be the same as the ramp weight. These values are compared with PCN values from FOMS Menu 105 (Airports Program) to determine airport suitability for the aircraft.

Oxygen Endurance: The descent in the event of depressurization must take place before the oxygen supply of the aircraft is depleted. This time is referred to as the oxygen endurance time. Enter the aircraft's oxygen endurance in minutes. For more details on how  Oxygen and Driftdown Escape Routes appear on the flight plan and how suitable airports are selected see Escape Routes Requirements. You can have up to 4 FL and Time entries.

Driftdown Method: Options are <O>Off, <W>Weight reduce, <E>Escape Routes, and <A>Automatic. If set to Off, NFP does not provide any escape routes. If set to Weight Reduce, NFP penalizes aircraft weight to meet MORA requirements (Method 1). If set to Escape Routes, NFP generates escape routes (O2 or drift down – Method 2) if MORA value is higher than 10,000 feet along the route of flight. If set to Automatic, NFP generates escape routes and if unable to do so safely, reduces aircraft weight as per Method 1.

All Routes: Options are Yes or No. If set to Yes, NFP checks MORA driftdown for all routes including alternates and reclear but not takeoff alternate. If set to No, NFP only checks MORA for the main route.

Error on Driftdown: Options are Yes or No. If set to Yes, NFP aborts a compute if a MORA check fails. If set to No, NFP only provides a warning.

Driftdown Engines: Options are 1EO (one engine out), Off (off), Half (half engines). If set to 1EO, NFP generates drift down escape routes based on one engine out performance. If set to Off, NFP does not generate any drift down escape routes. If set to Half, NFP generates drift down escape routes based on the number of engines divided by 2. For 3 engine aircraft, H = 2 engines out. If blank, the same behavior as Off occurs.

Normal Profile: Enter MORA normal driftdown key (or ? to search available options)

Icing Profile: Enter MORA Icing driftdown key (or ? to search available options)

ACARS Enabled: Select whether the aircraft is ACARS enabled.

Severe Turb TDR: Enter a light turbulence value - must be between 0.0 and 0.2. This value cannot be lower than the light value or the moderate turbulence value.

Avoid Icing PPI: Avoid Icing Percent Power Increase (0.0 – 2.0) above the entered value.

Icing Acft Cat: Icing PPI aircraft category (L = light / M = medium / H = heavy). If this field is blank, the NFP system looks at the Item 9 setting (wake turbulence category).

Vert Velocity:  Avoid thunderstorm exceeding the vertical velocity in meters/second entered.

Fly above by / Fly over Tops: Allow flight above thunderstorm by this value in hundreds of feet

Wind Source: This will override the default wind source set in Airline Code Parameters (FOMS 170).  Options are <U>UKM, <N>NWS, <T>Televent or blank

Auto Weather Chart / WxChart Buffer FL: use this field to add charts from a range of available FLs to the Flight Package. For example, a value of 50 with a cruise level of FL390 automatically adds charts FL340,FL390 and FL420. This value will override the value set in airline code parameters screens.

Auto Weather Chart / WxChart Specific FL: use this field to add a specific chart. For example, a value of 100 will automatically add a chart for FL100. This value will override the value set in airline code parameters screens.

Auto Weather Chart / WxChart Buffer Time: This buffer allows you to decrease or extend the time range when auto-selecting weather charts to add to the flight package. A positive number adds more charts and a negative number adds less charts. For example if the flight time was from 0900 to 1300, a buffer would extend the time range to 0600 to 1600. This value will override the value set in airline code parameters screens. This value will override the value set in airline code parameters screens.

ENR APU: Auxiliary power unit fuel per hour. The amount of fuel burned while the aircraft is airborne. The Fuel value is entered in LBS/KGS per hour. Fuel value entered here is multiplied by the flight’s EET and included in the total burn for the flight.

ETP APU: Equal Time Point APU fuel, included in the ETP scenario.

When set to Calculate in the Method field in the ETP Scenarios database, the N-FP system multiples the ETP APU fuel entry (LBS/KGS) from the Aircraft Characteristics database and multiplies it by the EET between the ETP point and the ETP alternates. This fuel is not included in the ETP required fuel for the selected scenario(s).

If set to Fixed, a Burn value in LBS/KGS per hour will have to be entered. This fuel will be included in the ETP required fuel for the selected scenario(s).

Gnd APU: Ground APU, fuel burned while aircraft is on the ground or at the gate.

Ground APU fuel can be displayed on a separate line in the format’s fuel burn block under required fuel as it is expected to be used prior to takeoff.

In this example, the Gnd APU is 440 LBS/KGS per hour. Notice the APU line item under the minimum fuel required line.

Gnd APU Time Before and After: Amount of time the auxiliary power unit is running on the ground before and after refueling.

Values entered are taken into consideration for multi-leg tankering calculations to determine how much fuel is required.

The flight plan format will show an increase in the taxi out fuel if the Ground APU time between refuel and Taxi Out is greater than zero. These fields are displayed on the flight plan with Taxi fuel parameters.

Customer Code 1, 2, 3: These fields are used for display only. Enter an alphanumeric digit to be used as reference for the aircraft.

NTMId: Enter the NOTAM filter key

ETP-POL: Enter the ETP Policy (A-Z) for this aircraft. This may be left blank, in which case the system will default to the policy specified in the Master Parameter file. This field is intended to allow you specify a policy for those aircraft that are non-standard.

TLS: Time Limited System time (in minutes) and used for ETOPS Beyond

ETP-F/L: Enter the flight level to be used for the ETP calculation.

CFSS: Cargo Fire Suppression System time (in minutes) and used for ETOPS Beyond

ETOP-SPD: Enter ETOP Cruise speed (LRC, IAS330, etc)

EepExp Min: Enter the EEP/EXP time in minutes.

ETOPS Time: Enter the ETOPS time in minutes.

ETOPS TAS: Enter ETOPS True Air Speed

ETOPS Distance: Enter the ETOPS distance.

Note: ETOPS Time and ETOPS Distance fields are optional. If they are left empty, the system generates circles based on values defined in the ETOPS-Min and ETOPS-TAS fields.

Hide: Hide ETOPS and do not display on the flight plan (Y/N)
RestrictETP: Disallow ETP if its outside ETOPS <Y>Warn, <N>Off, <E>Error

ETOPS-Time/ETOPS-Distance/ETOPS-Beyond: For twin-engine aircraft, the maximum number of minutes or the distance that the aircraft may diverge from an alternate during ETOPS flights, and the TAS that has been specified for use in calculating maximum distance from alternate for ETOPS flights. Selecting Y for Beyond will enable the ETOPS Beyond 180 minutes function. At least one scenario must have a value above 180 and be enabled for Beyond to be used for ETOPS Beyond 180 Minute operations, and one or both of the TLS (Time Limited System) or CFSS (Cargo Fire Suppression System) time fields must be filled in. The maximum value for these fields is 999.

ILS LTS: Approved for ILS LTS? (Y/N)
CAT I SA: Approved for CAT I SA? (Y/N)
CAT II SA: Approved for CAT II SA? (Y/N)
CAT II SA: Approved for CAT II OTS? (Y/N)
ARFF Level: Specify the ICAO Aircraft Rescue and Firefighting Code (ARFF) for an aircraft. Accepted values range from 1 to 10. 

Comments: free text to enter any details about the aircraft, character limit 108. There is currently no interaction between this field and any other program.
Updated: This field indicates when the last change in the fuel consumption bias was made, and will be filled automatically.
Src: Your initials are automatically added to indicate that you made the latest updates.

 

Edit Mode

If you wish to amend a record, select Edit mode from the command line, and enter either the aircraft ID, or registration, for the aircraft whose information you wish to edit. The record for that aircraft will be displayed, with the cursor on the aircraft type field. You may then press <Enter> to move the cursor to the desired field. To change any entry you may use the backspace key to replace one character at a time, or you may use <Ctrl>-X to erase the field for a new entry.

Delete Mode

Use this mode only if you want to remove the entire aircraft record from the file (e.g., if the aircraft has been sold or scrapped.)

Enter the aircraft ID or Registration. The record will be displayed, along with a Really DELETE? (Y/N) prompt.

You will not be able to delete an aircraft that has an outstanding MEL item against it; a Usage report will be printed indicating what must be deleted from other files before the aircraft can be removed from the system.

Video Mode

Video mode will enable you to view a single Aircraft Characteristics record at a time, and to step through the data file alphabetically (by Aircraft ID) by using the up and down arrow keys. If the ID you enter cannot be found, a Record Not Found, Press Enter for Next in File message will appear. You may return to a blank screen with the cursor positioned in the Aircraft ID field simply by pressing <Enter>. To exit to a Command Line prompt, enter <Q>.

Screen Mode

SUMMARY/FULL REPORT (S/F): Indicate whether you want a summary or full report.

Note: In Screen mode it is recommended that you only select Summary. In this mode an individual aircraft record spans three pages and hence cannot be seen in its entirety. Video mode is generally a better option for viewing these records. The Summary report displays only key elements from each record, such that each record fills only one line in order that many records can be displayed at once.

GENERIC/OWN (G/O): Indicate whether you want the report to include your Company (own) or generic records.

FIN (FROM-TO): Enter the range of aircraft FINS to be included in the report.

REGISTRATION (FROM-TO): Enter the range of Aircraft IDs you wish to have reported. The default values (that will report everything on file) are 0000 and ZZZZ. You may narrow this down to a single aircraft by entering its registration twice.

AIRCRAFT TYPE/SERIES/ENGINE: Enter the aircraft type designator if you wish to have records for only one type displayed. The default value is ALL (press <Enter>). This will produce a report containing all types of aircraft in your fleet. In either case the report will be sorted strictly by Aircraft Registration. If a specific aircraft type is selected, you can further refine you report by specifying the series of aircraft. If you select a specific series of aircraft, you can select a specific engine type, or press <Enter> for to select all engine types.

ETP POLICY: Refine the report by entering an ETP policy, or press <Enter> to include all ETP policy.

RESERVE POLICY: Enter domestic, international and reclear reserve policy numbers. Pressing <Enter> without entering a policy number in a field will include all of the corresponding reserve policies in the report.

FORMAT: Refine the report by entering a format number, or press <Enter> to include all formats.

TCAS EQUIPPED: Indicate whether to include TCAS-equipped aircraft in the report.

ACARS EQUIPED: Indicate whether to include ACARS-equipped aircraft in the report.

INS EQUIPPED: Indicate whether to include INS-equipped aircraft in the report.

Hardcopy Mode

Hardcopy mode functions in the same manner as Screen mode, with the exception that the report is sent to the printer, so you do not have the ability to terminate the report in mid-stream.

Quit Mode

Entering <Q> from the Command Line will return the Next PROGRAM-NUMBER prompt so that you have the option of going directly to your next program if you know the menu number, or of returning to the previous menu if you simply press <Enter>.
