What action acknowledges an ALDIS signal during Lost Comms?

Explanation:
Acknowledging an ALDIS signal during Lost Comms is done by rocking the rotor. This small, deliberate rotor motion provides a clear, visual acknowledgment to the signalman that you have received their signal. It’s quick, unambiguous, and doesn’t rely on radio communication, which may be down. Wagging the rotor head isn’t the standard acknowledgement and could be misinterpreted. Applying the collective or transmitting on the radio isn’t the correct way to acknowledge the ALDIS signal either—the former changes flight attitude unnecessarily, and the latter defeats the purpose of relying on ALDIS when comms are lost.
