Where is the Radio Transmit Select (RTS) controls located?

• A. Only EUFD
• B. Cyclic and EUFD
• C. Cyclic only
• D. The CCP controls

Answer: (B)

Radio Transmit Select needs to be reachable at the two main crew workstations so you can quickly pick which radio transmits without taking your hands off the controls. That’s why the RTS controls are placed on both the Cyclic and the EUFD panels. The Cyclic is the primary control area you use during flight, so having RTS there lets the pilot switch transmit without shifting grip. The EUFD panel provides a convenient secondary access point for another crew member or for quick operation at the front station. The CCP controls aren’t the standard RTS locations, so RTS being available on Cyclic and EUFD ensures you can transmit from either position as needed.
