3 hours ago3 hr I've been flying using INS+GPS navigation mode and decided to test GPS-only navigation mode to avoid having to deal with INS.The problem is that I'm having trouble getting the aircraft to recognize the GPS route in this mode. I import the route into the GPS, ensure it's in GPS instead of VLOC, but the aircraft doesn't seem to recognize the route. On the HSI, the indicator of how many miles are left to the next yawpoint shows zero and doesn't point in the direction of the next waypoint. Because of this, the A/P doesn't follow the route.Curiously, this only happens when I load the aircraft from the gate, in cold & dark mode. If I load the aircraft from the runway, with the engines already running, the aircraft does recognizes the GPS route and follows it normally without any problem. It's as if, when loading from cold & dark, I would have to perform an alignment for the aircraft to know where it is, but how can I do that if ''GPS mode only'' removes the INS?Can someone tell me what I'm doing wrong?
