Hello there, using the V/S function of autopilot, during descent, the target rate of descent reset to 0 automatically, way way before target altitude, and I have to reselect my rate of descent.
For example, I was on descent form FL270 to FL070, and maybe 30 sec after leaving FL270, the V/S reseted, and I select again -20 and maybe 30 sec after reste again,... and so on.
Is it a bad user utilisation, or a known bug?
Thanks.
Happy flying.
