The course and energy of the wind may have an effect on raise and Guy Gratton, a professor of plane take a look at and analysis at Cranfield University, believes this was the issue for EasyJet’s flight EJU7008 from Southend.
“The wind, being 50° off the runway heading, would give almost no headwind. Headwind is usually there – in England the wind is usually from the south-west, [which is] aligned with Southend’s runway, which points at 230°, and helps shorten take-offs,” he says.
“On this occasion, it wasn’t and there may as well have been almost no wind at all. This would be quite unexpected and can indeed cause problems,” he provides.
The issues have been noticed when the security calculations have been finished, the airport says.
One approach to overcome the issue, Gratton provides, is for the plane to journey additional alongside the runway to present it time to succeed in the required thrust.
At Southend Airport, nonetheless, this was not doable as though the runway was prolonged in 2012, it’s nonetheless comparatively quick at 1,856m (6,089ft).
By comparability, Stansted Airport’s runway is 3,049m (10,003ft) and Luton Airport’s is 2,162m (7,093ft).
Gratton says one other approach to deal with the difficulty is to make the plane lighter, which normally imply passengers disembarking or eradicating baggage.
He provides it’s a “straightforward solution and it was quite right that EasyJet’s dispatcher and captain would not take-off until the airplane was within limits”.
