FOMS Menu 253 (Driftdown Fuel Program)

This program allows you to view Driftdown Performance data. This data is maintained by the NAVBLUE Performance team.

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 permits you to specify the aircraft, the driftdown profile, number of engines, the range of ISA Deviations, and the range of weights for which you wish to have data reported. When the report displays 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. The exception is the report is sent to the printer and you do not have the ability to terminate the report in midstream.

Quit Mode

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


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