The Australian Transport Safety Bureau (ATSB) released a training video highlighting some near catastrophes that occurred after experienced pilots incorrectly entered takeoff data in the flight management computer aboard large airline aircraft, including a Boeing 747 and 767 and an Airbus A340.
The video suggests the need for a takeoff performance monitoring system to call attention to poor aircraft performance after the sort of human error that caused these three near accidents. The aircraft also suffered significant damage from tail strikes during the takeoff runs when the flying pilots attempted to pull the aircraft into the air.
Not all such incidents involve a tail strike. A Qantas A380 crew’s data entry incident at Los Angeles International Airport (KLAX) in October 2011, for example, did not. However, it was later shown to be caused by the interruption of the cockpit crew at a critical time during their pre-takeoff checks.
