This program generates a report of all of the potential tankerage opportunities for all flights in the Flight Status data file for the selected day. The program works on an aircraft-by-aircraft basis, starting from the last flight of the day to the first flight. Where a tankerage opportunity appears due to the fuel price differential, the program will calculate a flight plan based on the forecast winds, planned payload, and known next-leg fuel requirements to determine the potential tankerage savings. All computations are run in background, and a hardcopy report is generated each time the program is run.
The modes for this program are:
Flight Day: The only entry required to initiate the computations is the desired flight day. The only permissible entries are the current day, and the following day (any other selection would not have the correct winds available for accurate calculations).
Etd/Std: The report can filtered to display the flights using the STD or ETD based on user preference. ETD is the default selection if no input is made to the field.
Same input options as in screen mode are available in Hardcopy mode, the results will be sent to the default printer.
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> .
Looking at the report, column by column, it is read as follows:
Flt#: This is the flight number stored in flight status
ORIG/DEST: This indicates the origin and destination of the flight being looked at.
FIN: This is the FIN assigned to the flight. If there is no FIN then the flight can not be checked for tankering in this report.
ETE: This is the time enroute taken from the route analysis process.
UNIT: This shows the units that are being displayed in the report.
PAYLOAD: Payloads are either an estimated payload or an actual payload if known. If estimated an E will appear next to the payload value. An estimated payload is approximately 85% of the maximum payload capacity of the flight.
Tankerage-Fuel (Next Leg): This is the amount of fuel the system has determined will be required to be tankered to the next station to avoid or minimize uplift of fuel at the next station
Tankerage-Fuel (Max): This is the amount of fuel the system has determined is the maximum amount that can be tankered to the next station.
Savings/1000-Units (Next Leg): This is the amount of savings in dollars associated with carrying the suggested next leg fuel. As an example, if $6.98 were shown in the Saving/1000-Units (Next-Leg) field, it would indicate that the unit (per 1000) savings for this flight would be 6.98. If 30,000 kg were tankered, the saving would be $6.98 * 30 = $209.40.
Savings/1000-Units (Max): This is the amount of savings in dollars associated with carrying the maximum tankerage fuel. As an example, if $6.98 were shown in the Saving/1000-Units (Max) field, it would indicate that the unit (per 1000) savings for this flight would be 6.98. If 50,000 kg were tankered, the saving would be $6.98 * 50 = $349.00.
Note: Sometimes the report will display --- in it. This indicates that the system was unable to perform a tankering analysis either because the route analysis had not been completed or the flight leg sequence is not correct. When the flight leg sequence is the cause of this an asterisk will also appear on the right hand side of the report on each line that could not be completed due to this condition.
