In the air, and after loading an alternate flight plan, the autopilot acts as if there is no flight plan (no GPS Mode). Autopilot then fails to respond to "Fly Direct To". I land and load a flight plan and the autopilot goes into GPS Mode.
In the air, and after turning off the iFly and powering it up, the autopilot acts as if there is no flight plan (no GPS Mode) regardless of which Flight Plan is loaded.
