An interesting concept...
"JetBlue Airways, today announces plans to retrofit its entire Airbus fleet with noise-reducing vortex generators. This move reflects JetBlue’s continued commitment to the communities where its customers and crewmembers live and work. Beginning in 2015, JetBlue began taking delivery of new aircraft with vortex generators already installed. JetBlue is committing to add the devices to its 138 remaining Airbus A320 family aircraft through 2021. The small devices disrupt wind over ports on the wing which can produce a “whistling” tone during approach into an airport.
JetBlue is following the lead of Lufthansa."
Vortex generators will be installed on 130 existing JetBlue A320 aircraft and eight JetBlue A321 aircraft during their existing scheduled heavy checks with the full fleet wide install expected to be complete in 2021. All future Airbus orders will be delivered with vortex generators already installed"
There was the 320 howler, didnt hear about the whistler....
