Great airplane. Its my current top airliner to fly! Thank you Inibuilds for developing this classic trijet. Not sure if anyone else is experiencing this issue, but as the title suggests, my GPS randomly resets during normal flight ops. I can only use INS as a reliable source for navigation. When the GPS resets, all the settings and positions remain, but its rather annoying that I have to keep pressing "ENT" to get to the map view of in the GPS.
