Took the Longitude from London Luton (EGGW) - to Cork (EICK):
The flight was pretty…strange. Even though Autopilot showed NAV mode ON, somehow it turned off and the airplane turned left to 180. I was quite lucky that at the time there was no ATC online in the area as it took me a while to notice, I was preoccupied by going over the arrival and approach plates and their data.
