ionic81 Posted April 1 Share Posted April 1 Hi, I followed iniBuilds video tutorials on how to correctly start the descent from TOD but the airplane always arrives near the airport too high. In the video the guy sets the target altitude and then presses PROFILE button near TOD in order to activate P.DES mode. I tried it, it doesn't work. Another possibility, for me this is the correct one, is to set the target altitude, pull the knob in order to arm the P.DES mode, and then the airplane automatically acitvates P.DES mode when reaches TOD. The behaviour is the same as above. Here you'll find a detailed description of what happens, I read from a real pilot that what all says about the bad VNAV performance of A310 is not real, the system is not perfect but in the real life it doesn't act like in the simulation because in this way would never get certified. So, for me there is a bug. In order to replicate the problem, try to do this flight (30 minutes): Fiumicino - Pisa, Cruise altitude 12500 feets LIRF (34L) - LIRP (ILSY04R) Flight Plan: NENI7M NEMBO T313 ELB M729 NORNI NORN1R and you will arrive too high on the airport. As soon as the airplane reaches TOD the VDEV rapidly decreases (negative value) like we need to maintain altitude (???) Link to comment Share on other sites More sharing options...
