HHHMMMM.... the part about flaps.... u shouldnt have been climbing at 20 degrees flaps, maximum permissible in a climb is 10!
John, correct on recommended vs. permissible...no prohibitions against climbing with 20.
Ever had the flaps fail to retract during a go-around due to a switch or microswitch failure? I sure have. Knowing how to fly with something other than climb flaps at that point may be important.
