Green transmit lights illuminate when a transmission on the respective radio is made, from which cockpit(s)?

• A. Both the forward and rear cockpit
• B. The rear cockpit only
• C. The forward cockpit only
• D. Neither cockpit

Answer: (A)

In a dual‑control cockpit, the radio’s transmit function is shared between both workstations, and the transmit indicator is visible at both seats. When either pilot keys the mic or presses the push‑to‑talk for that radio, the transmitter is active, and the green transmit light is shown in both cockpits. This ensures both pilots know when transmission is happening, preventing confusion during communication. So the lights illuminate in both the forward and rear cockpit, not just one.
