Martin,
müsste man genauer anschauen, warum das passiert. D.h., ob die VNAV Disconnect Bedingungen in der Situation, wo es bei dir passiert zutreffen oder nicht :
Now, under "normal" conditions, this is when VNAV will not engage / disconnect
- PATH : speed is over 20 knots above current target (real life : 15, but I relaxed it a bit). You will get the DRAG REQUIRED when speed is more than 10' knots above target.
- if the angle to be flown (inserting an alt constraint for instance) in greater than 7 degrees, VNAV should and will disconnect
- if there is a wpt with a speed restriction and no alt restriction
- if next alt (constraint or MCP) to be reached is under the AC in CLB or above it in DES
- if because of entering a too high cruize alt the path can not be constructed (no time to climb and descent etc.)
Wenn VNAV Disconnect ausserhalb dieser Bedingungen passiert, wäre es ein Bug
