FOMS Menu 230 (Performance Profile Key Program)

Field

Description

Profile Key

Enter a code to designate the profile that you are going to add. This code will subsequently be used in the cruise field of the Flight Plan.

Although you can use any code of your choice, for the sake of commonality the following choices are suggested:

• STD for all fixed Mach Number profiles. (You do not need to enter a key for each and every Mach number, the STD key will serve for all such profiles.)

• LRC for Long Range Cruise

• HSC for High Speed Cruise

• 1EO for 1 engine out

• LGE for Landing Gear Extended

• POD for extra engine Pod

• YDI for Yaw Damper Inoperative

• CI

Display As

Enter a name to display for the performance profile key.

Aircraft Type

Enter the aircraft type.

Series

Enter the aircraft series. The <?> Search function may be used in this field.

Engines

Enter the type of engines. The <?> Search function may be used here too.

Units

Enter the unit of weight (LBS or KGS).

Aircraft ID

This field is optional, and can only be accessed if the Aircraft Type field has been skipped. This will permit you to set up a special profile grouping that is different for one particular aircraft. 

Example: If you want the climb profile associated with LRC for one particular aircraft to differ from that in use by the rest of the fleet. Enter the aircraft identifier used in the Aircraft Characteristics file.

Abnormal (Y/N)

Indicate whether this profile is considered as normal or abnormal. For the purpose of this definition, normal is considered to be any profile that uses the full complement of engines, and does not involve any special restrictions to flight planning.

Profiles flagged as abnormal are placed at the bottom on the list of profiles on the Plan screen.

Used for Alternate Route (Y/N)

Enter whether or not the specific cruise profile will be used for the alternate as well, yes <Y> or no <N>.

ETP Allowed (Y/N)

For some profiles which involve engine-inoperative conditions, it may be impractical to use an ETP calculation that involves the loss of 50% of engines. If you select <N> in this field, then the ETP routine will only calculate the position of the ETP along track, and will not perform any fuel burn calculations.

Description 

Enter a description of the performance profile key, e.g. …..COST INDEX 049….. .

1. Climb

Profile

Enter the main designator for the climb profile which you want to be associated with this cruise profile. The <?> Search function can be used in this field.

Auxiliary Profile

Enter the auxiliary climb profile (e.g., 250/300/M80), or use the <?> Search function to select from the available options.

Engines

Enter the number of engines that apply to this climb profile.

Note: The number of engines may not be the same as the number of engines in the cruise profile. For example, if you were creating an engine-inoperative profile for a B727-200, and there was no 2-engine climb data available, then a 3-engine profile might be selected as the best available substitute.

Date

This is a display only field which will be filled automatically by the program with the current system date.

Src (source)

Enter your initials.

2. Cruise

Profile

Enter the cruise profile designator for the cruise performance data that you want to be used in conjunction with this profile. The <?> Search function may be used to select from the available options. For fixed Mach, simply enter <STD>. This will represent all available fixed Mach profiles.

Engines

Enter the number of engines that apply to this performance data.

Date

This is a display only field which will be filled automatically by the program with the current system date.

Src (source)

Enter your initials.

3. Descent

Profile

Enter the main designator for the descent profile which you want to be associated with this cruise profile. The <?> Search function can be used in this field.

Auxiliary Profile

Enter the auxiliary descent profile (e.g., M78/280/250), or use the <?> Search function to select from the available options.

Engines

Enter the number of engines that apply to this descent profile.

Date

This is a display only field which will be filled automatically by the program with the current system date.

Src (source)

Enter your initials.

4. Hold

Profile

Enter the main designator for the descent profile which you want to be associated with this cruise profile. The <?> Search function can be used in this field.

Auxiliary Profile

Enter the auxiliary descent profile (e.g., M78/280/250), or use the <?> Search function to select from the available options.

Engines

Enter the number of engines that apply to this climb profile.

Description

Enter a description of the profile you have created. This description will be displayed on the command line whenever the <?> Search function is used to select this particular profile in the Flight Plan program, so it is important that it provides sufficient detail for the dispatcher. Any discrepancy in the number of engines used in the various components of the profile should be indicated.

Example: If it were necessary to use a 3 engine climb for a 1EO profile, then this should be indicated in the description so that the dispatcher may be informed and can pass the information on to the crew receiving the plan.

Date

This is a display only field which will be filled automatically by the program with the current system date.
