Boeing 747 Flight Management system (FMS) Tip

Hello everyone and how do you do?
Took 2 minutes in the B747-400 sim to show you this quick tip for FMS manipulation. Some airway segments or routes, require that a specific Mach number is maintained. This is done to maintain separation distances between aircraft. On the B747, the speed can be inserted manually on the VNAV page or indeed, speed intervention used to maintain the required Mach number. A better way of managing it is to insert the Mach number at the start waypoint and then insert ECON at the end segment of the restriction. Watch the clip.
Hope it helps…Chi Di Gin! Later!✈️✈️✈️✈️

Why is everything so green? I guess that will cause eye fatigue!
Airbus MCDUs are much organised and nicely code colored.
Don't get me wrong, the 747 is the queen of the sky indeed!

Does the 737NG, 777, 757,767 also have this function?
Thanks for showing this function.

The 777 has. You can see it in the „Just Planes Air Canada Boeing 777-200LR Vancouver-Sydney“ videos here on youtube. Inklusive fixed Steplcimbs.

Thanks!

This function is only available on the Dash 8 & the 747-400 with the NG FMS upgrade.
The legacy FMS still requires any “hard coding” of a fixed MACH NO in the VNAV Pages, or by SPD INTV on the MCP.

@@dingerbell100 correct - as I stated in the narrative.

You confirmed that the Dash 400 also has this function in the newer FMCs.
Can you name the least softwareversion which contains this feature in the FMC for the -400, please?
