I fly the Vision Jet a lot, lately almost exclusively. Usually IFR flights built via SimBrief. Since a couple of flights, I ran into the following problem: On descent, I do not get the TOD markers in the Nav display anymore. The annunciator panel in the PDF says „Path“ in white, VNAV button on the AP panel is lit, AP is active, the lower altitude of my next waypoint is dialed in, but the plane never does the automatic descent. I have to do the descent via VS.
In the past, my VNAV descents worked flawlessly, starting some seconds before reaching the TOD.
What am I doing wrong? Thanks in advance!
