VNAV speed

[Stevens]

Gentlemen,

how can I get VNAV speed to work? I am talking about the speed bug in the PFD. When I select a speed in the FCP, on the PFD I always have the speed bug in blue color.

Yesterday I saw on the VNAV SETUP page in the FMS a prompt showing "Resume Mach 0.80". I clicked on it and suddenly I had a magenta speed bug in the PFD.

Today I tried to do it again, but on the VNAV SETUP page it never showed me a prompt to resume VNAV speed.

Does anybody know how I can get VNAV speed (magenta speed bug) to work? Graeme?

Thanks!

With a flight plan entered, ensure you entered a cruise altitude in the PERF page (PERF x 2, LSK1L).

Check the flight plan shows climb (increasing crossing altitudes to cruise) and that the altitude selector is set above the current aircraft altitude.

Press VNAV on the FCP, then press FLC, then in the FMS press PERF x 2 and select "RESUME xxx". VNAV will now control the speed as per the VNAV speed schedule.

Thank you very much! That helped!
