Easyjet A319/A320 vortex generator retrofit April 2016
Retrofit of vortex generators Fuel over pressure check panels , EZY aircraft have one on each wing. Tonal noise is reduced With VG retro-fit Averaged Sound Power Spectral Density at 40-140° - TAS 240 80 75 2012 Sharklets NCFT with VG C5/C5* 70 2012 Wing Tip Fences 65 NCFT with VG C5/C5* Power Spectral Density (dB/Hz) 60 2004 FT with VG II 55 50 2004 FT without VG 45 40 100 200 300 400 500 600 700 800 900 1000 Frequency (Hz)
easyJet fleet statistics easyJet currently have a fleet of 248 A319/A320 aircraft. We have now retrofitted 88 aircraft with Vortex Generators and expect to complete the 100 th aircraft in early June. In addition to the 88 aircraft retrofitted, we have in the meantime taken delivery of 37 new ai aircra raft with pre-fitted modifications. This means that we now have 125 aircra raft with vortex generators, just over 50% of our overall fleet. We expect that our entire fleet will be compliant by March 2018, this represents 197 retrofit procedures. At Peak Summer 58 of our aircraft are currently based in Gatwick As of today, 56% of aircraft at LGW are compliant, by peak Summer (July) this will rise as we disproportionately deploy these aircraft to Gatwick Operations
Future fleet expansion/replacement easyJet currently have a fleet of 248 A319/A320 aircraft. The future replacement and growth program is modelled around the A320neo aircraft In the next 6 years we will take delivery of a minimum of 130 new A320neo aircraft Gatwick fleet size currently sits at 58 aircraft (seasonally dependent) All new aircraft in to the easyJet fleet will have vortex generators pre fitted Fleet delivery plan subject to change
