I can't see any tooltip text telling me that altitude hold is engaged. When I press the mouse wheel (middel-button-click) nothing happens regarding hold mode. Is there something I'm doing wrong?
Oh my.. I reworked the manual from the FSX one and have missed that one..
The original AP does not have an altitude hold. The FSX version has it, but I decided to go ahead with "as real as possible". It's relativly easy to trim the plane into level flight and nobody complained about it while testing.
