The effects of three different levels of pilot training on the breakout response of pilots and the Boeing 747-400 aircraft were studied. The study examined response during ATC-directed breakouts on final approach and was conducted in three phases. Phase 1 tested performance during manual and autopilot-coupled approaches given current procedures and pilot training. Phase 2 tested the effect of increased pilot situational awareness and proposed ATC breakout phraseology on breakouts during manual and autopilot-coupled approaches. Phase 3 tested the effect of two B747-400-specific breakout procedures on breakouts during autopilot-coupled approaches. Pilot preferences regarding procedures and the tested training materials were also solicited.
