In truth, it is the pilot, not the controller, who is ultimately responsible for the safe outcome of every flight. It is the pilot, not the controller, who ultimately determines the heading and altitude to fly. If the controller steers a pilot into a restricted or prohibited area, it's the pilot, not the controller, that receives the violation. If a controller vectors a pilot into the side of a mountain, it's the pilot, not the controller, who dies.
Does This Mean that the Pilot Can Choose to Ignore ATC Instructions?
Of course not! FAR 91.123(b) states that Except in an emergency, no person may operate an aircraft contrary to an ATC instruction in an area in which air traffic control is exercised.
Well, if the pilot is the master and ATC is the servant, how do you explain FAR 91.123(b)?
Welcome to the gray area of aviation. As any experienced pilot knows, aviation is not a "black and white" world, with right answers and wrong answers. Instead, aviation is a world of shades of gray. It's a world of individual interpretation and judgement, not blind obedience to regulation. It's a world where the pilot exercises COMMAND authority over the safety of his flight. How, then, does pilot command authority square with FAR 91.123(b)? [I should point out that there are still pilots who "fly by the book." Right/wrong, black or white . . . with no shades of gray. Fortunately, this myopic view of aviation is fading away.]
The best way to reconcile pilot command and FAR 91.123(b) is to recognized and accept the fact that the pilot and ATC represent a flight team. Rather than working in opposition, e.g., ATC says go one way and the pilot wants to go another way, the pilot and ATC decide jointly on what will work for the best outcome of the flight. But remember, every team has a captain. And that captain is and always has been the pilot, not the controller.
Okay . . . Who's the Boss?
Again, the pilot is the boss! The pilot files his or her flight plan. ATC issues clearances in accordance with that plan. If the pilot does not like or is unable to accept those clearances, he advises the controller, and a new set of clearances are issued. This process continues until both the pilot and ATC agree on the the flight is to be flown. Sound confusing? Perhaps so, but here's a list of six rules that will help you, as the pilot, to remain in control of your flight:
Rule #1: Don't be shy...ask ATC for what you want.
Rule #2: Treat every ATC clearance as the opening bid in a negotiation.
Rule #3: If ATC turns down your request, be persistent.
Rule #4: If you're unable, say so...and make ATC a counter-offer.
Rule #5: It sometimes helps to give ATC the reason for your request.
Rule #6: Don't hesitate to use your command authority.
