EasyJet to use ‘green taxiing system’
London, February 14, 2012
EasyJet, the UK’s largest airline, in collaboration with Honeywell and Safran, has announced that it will be the first airline to support the development and trial of the innovative new electric green taxiing system (EGTS).
Due to the high frequency and short sector lengths of easyJet’s operations, around 4 per cent of total fuel consumed annually is used when its aircraft are taxiing. Its aircraft average is 20 minutes of taxi time per flight – the equivalent of 3.5 million miles a year.
The first operational trials are expected to start in 2013, a statement from the airline company said. Honeywell and Safran are targeting to offer the electric green taxiing system either on a new aircraft or as a retrofit solution to in-service aircraft as early as 2016.
The development and trial will help establish whether the estimated savings can be realised and also quantify other benefits. easyJet will also assist in establishing the airline standard operational procedures for aircraft equipped with the system, the statement said.
Ian Davies, head of engineering and maintenance, easyJet, said: “EasyJet is always seeking innovative ways of reducing our environmental footprint as well as our operating costs so this technology is of great interest to us. This collaboration with Honeywell and Safran allows us to bring our huge experience of high frequency and high levels of operational performance to the partnership to ensure that the solution meets our needs.”
Yves Leclère, executive vice president, transformation, Safran, said: “We are very pleased to partner with easyJet on the electric green taxiing system. It is a clear vote of confidence from a major airline which gives significant credibility to our system and value model.”
The EGTS allows aircraft to taxi without requiring the use of aircraft engines by using the auxiliary power unit (APU) generator to power motors in the main wheels.
Each of the aircraft’s powered wheels are equipped with an electromechanical actuator, while unique power electronics and system controllers give pilots total control of the aircraft’s speed, direction and braking during taxi operations.
The system would therefore reduce, if not remove altogether, the need for tugs to manoeuvre aircraft in and out of stands, the statement said. – TradeArabia News Service
