Would be pretty cool to have the Power Transfer Unit (PTU) sound added to the Airbus aircraft.
It is the power drill sound that you hear after pushing back.
After pressing “STOP PUSHBACK” or “Brake” (only if pushing back), the sound of the PTU would go off. This update could come out whenever the devs push an engine sound update later in the future or whenever.
It shouldn’t make a sound if you’re using a towbar and do it right, however, if your pushback driver binds it up and you have to force it off, it will make a bit of a clatter.
Are you sure it’s not some system powering up on the aircraft, on all the planes I’ve been on or moved, I’ve only heard the towbar make a sound twice. The 2 times were times we busted the tow bar too.
MaxSez: @Keegan_Gidley. You sure it a PTU pumps transferring hydraulic fluid? Or a combination APU wind down + packs recycling after ground power has been removed?
