Came up in class last night. Instructor didnt know the answer. Scenario You accept a LAHSO clearance. On short final you the runway becomes fouled (car, plane, dog, bird on runway, micro burst or whatever)and you cant land. The frequency is too busy to get in before you need to take evasive action (go around across hold shor area, or turn off runway heading, or whatever). What action is least dangerous and least likely to run you afoul the FAA? Would this even be a FAR violation?
