Bugs in VNav, To Davide, for information Options

[Cyril Murat]

Hi Davide.

For information, I’ve noticed 2 bugs that I think haven’t been reported yet:

1- VNAV in descent: Let’s say the successive points in legs are XXX, YYY and ZZZ.

If I put a speed restriction on XXX (220 for example), it is copied in YYY and ZZZ so the speed restriction should be applied to all the next points. The problem is that after passing XXX (when YYY becomes the next point), the restriction is forgotten and the speed increase from 220 to 250 again. I have to put the restriction manually to all the next points to keep the speed.

2- In VNAV too: it often happens that as the aircraft descends, the VMO limit pointer descend suddenly bellow the actual IAS and that an overspeed occurs. I guess that descending in the real a/c in VNAV never leads to overspeed… I may be corrected.

That said, may I ask you confirmation that you’ve read this and can you confirm us customers that Leonardo is back to work and will try to correct the know issues ?

Happy new years, best regards, happy flights and safe landings.

Cyril
