Q: Can this XLR5 cable work in the Pilatus PC-12NG?
A: No, this is for Aibus. The 5-pin XLR5 often gets confused with the 6-pin LEMO connector. I suspect your Pilatus PC-12NG has the 6-pin LEMO jacks in the panel so you would want to get the Bose A20 Cable Assembly With Bluetooth - Straight Cord, Panel Powered LEMO Connector instead. For more information, see our Guide to Aviation Headset Plugs and Jacks.
Q: May i use xlr5 CABLE IN ATR?
A: Yes, many ATR aircraft also have the XLR5 jack and this will work great.
Q: I'm looking for a replacement cable for my a20 headset. Is it possible to get a coiled cord version of the 5 pin Airbus plug cable. Preferably without Bluetooth?
A: Bose doesn't make a coiled cord version of the XLR cable assembly. But, we do have the straight cord, no Bluetooth, 5 pin XLR cable for Bose A20 here.
