Low-flying Jet flight: Pilots erred in calculating take-off parameters

An initial probe into the reported 'unsafely' low take-off by a Jet Aircraft from London Heathrow on August 30 has revealed that the pilots based their take off calculations like speed and thrust on the full length of the runway. This despite the fact that the full length of the runway was not available and only a part of the runway was there for take off that day. This critical error meant that the pilots reportedly erred on both the take-off speed and thrust, endangering the safety of the Mumbai-bound aircraft and people on board.
"Due to this serious calculation error by the pilots, the plane did not achieve the desired height after getting airborne. The Boeing 777 had an altitude of was just 120 feet when it was over the airport boundary wall. And before that, at a point it had an altitude of 35 feet on two engines — while that is the altitude that is achieved by a single-engine jet," said a senior official of the Directorate General of Civil Aviation (DGCA).
The regulator has since grounded both the pilots. "The pilots did not inform the airline about this unsafe altitude take off. People living near Heathrow complained to the local authorities, who then told London aviation authorities. They, in turn, told our aviation agencies," said the official. The Aircraft Accident Investigation Bureau (AAIB) is probing this case.
