Frequently Asked Questions

Do I need a new headset when I switch aircraft types?

No. You usually do not need a new headset when you change aircraft. A passive adapter cable converts your existing headset plug to the jack the new panel uses, so one good headset can serve a piston trainer, a helicopter, and a panel-powered cockpit with the right adapter.

Which headset adapter do I need to go from a GA dual plug to a helicopter?

Use a GA to helicopter adapter, which converts the two separate GA plugs into the single U-174 connector that helicopters use. To go the other way and use a helicopter headset in a fixed-wing aircraft, you need the reverse helicopter-to-GA adapter instead.

Do aviation headset adapters supply power to the headset?

No. Headset adapters are passive cables that only reroute the audio and microphone connections between plug types. Aircraft power comes from the panel jack itself, such as a LEMO 6-pin or XLR-5 connector, not from the adapter, so confirm your headset matches the new jack's power source.

What is the difference between a portable and a panel-mounted intercom?

A portable intercom is a small battery-powered box you plug into existing headset jacks, so it adds crew communication with no installation. A panel-mounted intercom is wired into the aircraft electrical system for cleaner audio and no clutter, but it requires professional installation and an avionics shop.

How many places should my intercom support?

Match the number of places to the most headsets you will use at once. A two-place intercom covers a pilot and one passenger or student, while a four-place unit suits a full cabin. Many four-place models also offer crew-and-passenger isolation so the front seats can talk privately.

What is the difference between a mono and a stereo aircraft intercom?

A mono intercom sends the same audio to both ears, while a stereo intercom delivers separate left and right channels and supports stereo music or device input. Stereo units typically auto-mute that music when the radio transmits, so communication always takes priority over entertainment.
