haseen 5 Posted August 28, 2016 Share Posted August 28, 2016 Dear: I am talking about how a fully managed (lateral and vertical) NPA is flown in a A320 and what are its prerequisites. I saw a you tube flight deck video relating to the subject. After arming APPR button and pushing the HDG-V/S/TRK-FPA, on the FMA it shows APP NAV in the roll window and ALT in the pitch active window, FINAL is shown in the pitch arm mode window. FCU altitude is set at 2000. At certain point, may be, at FAF, pitch active mode window changed from ALT to FINAL. The pilots didn't reduce the FCU altitude value, as if, the plane is capturing a typical ILS Glide slope. But there is no radio GS as it is a VOR approach. My questions are: 1. What logic makes the plane descend without any further pilot action? 2. Is the plane following a line drawn between FAF altitude say 2000 ft and the MDA say 450 ft? 3. If there is no approach procedure in the FMGC nav database and if I make place/bearing/distance way points along the runway center line approx. and set speed/alt constraints, will this NPA procedure work? Thanks for your time and best regards, Haseen Ahmad Bangladesh. Link to comment Share on other sites More sharing options...
