Aviation News – Two easyJet Airbus A320 flights operating out of London Luton Airport (LTN) and Manchester Airport (MAN) were involved in separate serious takeoff incidents just weeks apart due to calculation discrepancies. The flight crews executed departures from runway positions that differed significantly from the location coordinates used during their pre-flight planning and performance assessments.
The safety scares occurred because both aircraft entered their respective runways from different intersection entry points than originally assumed, unexpectedly reducing the physical runway available for departure. This deviation created a dangerous data mismatch between the flight management system parameters used by the crew and the actual physical starting position of the aircraft on the ground.
While both flights ultimately departed without damage or injuries, safety investigators are examining how the errors bypassed cockpit validation protocols within such a brief timeframe. The back-to-back events involve one of the continent’s largest low-cost carriers and have put a spotlight on standard airport navigation procedures and airline safety management systems.
Pre-flight takeoff performance calculations rely on precise entry points to determine required engine thrust settings, acceleration rates, and safety speeds. When an aircraft departs from a shortened intersection without adjusting these metrics, it significantly narrows the safety margins needed to clear obstacles or safely reject a takeoff in an emergency.
