A320 PTU Sound
THE "DOG BARKING SOUND" IN THE AIRBUS A320 FAMILY If you’ve flown on an Airbus aircraft, such as A320 or A321, you may have noticed a barking sound that resembles a dog barking. This noise is generated by the Power Transfer Unit (PTU) and indicates that everything is functioning normally with the aircraft. Let me take a moment to explain what a PTU is.

28K views · 173 reactions | Ever heard a barking dog sound on an Airbus A320? Don’t panic it’s just the Power Transfer Unit (PTU) balancing hydraulic pressure between the aircraft’s systems. Totally normal, totally safe. Recently, a JetBlue passenger panicked during taxi after hearing that same sound and tried to open an emergency exit, mistaking it for a mechanical issue. #jetblue #airbus #aviation #fblifestyle | Filipina Cabin Crew | Facebook
