FOMS Menu 253 (Driftdown Fuel 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.

This program will allow you to view driftdown performance data.

The values displayed are:

time to reach stable altitude in minutes

fuel burn from cruising level to level-off in pounds or kilograms

still-air distance to level-off

final level-off altitude (flight level) for each increment of initial cruising weight, flight level, and Temperature Deviation

The available modes are:

Graph

Screen

Hardcopy

Quit

Graph Mode

Graph mode allows you to enter criteria and have the information displayed in a graph. The graph opens in a separate browser window.

Screen Mode

This mode allows you to view the data for the selected driftdown profile of a specified aircraft. The report selection screen will permit you to specify the aircraft, the driftdown profile, number of engines and the range of ISA Deviations, and the range of weights for which you wish to have data reported.

When the report is displayed on screen you may press <Enter> to go to the next page. You may escape from the report at any time by entering <Q>.

Hardcopy Mode

Hardcopy mode functions in the same manner as Screen mode, with the exception that the report is sent to the printer and that hence you do not have the ability to terminate the report in midstream.

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>.
