I am a PPL, but am also an anesthetist. It occurs to me that there should be a simple way to use a GPS-oriented system to ensure takeoffs AND landings on the correct runway, at least at airports that are designated for jet service. We have similar "goof-proof" systems up and running in the operating theater, inspired by lessons learned from our aerospace colleagues. I do know that there is a lot of "clutter" and distraction prior to takeoff and landing, but perhaps a simple system could be designed to prevent these situations from arising.
