Hello fellow pilots!
I just completed a flight KMSY - KORD and wanted to start the return flight (not quitting the flight).
I took off and activated LNAV. But it just flew the runway heading of 270/280. I tried activate another leg but nothing.
Disconnected LNAV and AP and I could turn up and down, no problem.
Turned LNAV back on and it turned to the same heading.
Tried to go direct to KMSY but nothing happened.
