What is the proper Lost Comms procedure sequence?

• A. Make all calls in the blind; Squawk 7600; Overfly active runway 700' MSL & 70 KIAS; Turn downwind, look for ALDIS lamps; Rock rotor only to acknowledge ALDIS signal
• B. Squawk 7600; Make all calls in the blind; Overfly active runway 700' MSL & 70 KIAS; Rock rotor to acknowledge ALDIS signal; Turn downwind, look for ALDIS lamps
• C. Overfly active runway; Make all calls; Squawk 7600; Rock rotor to acknowledge ALDIS; Turn downwind
• D. Rock rotor to acknowledge ALDIS signal first; Then Make all calls; Squawk 7600; Overfly active runway

Answer: (A)

When radio failure happens, you follow a deliberate sequence that keeps ATC informed and gives you a safe path to land. Start by continuing to attempt communications on the assigned frequency to reestablish contact while you also set your transponder to indicate a loss of communications. Next, proceed to overfly the active runway at a low, controlled speed and altitude (700 feet MSL and 70 KIAS) so you can visually assess the field and prepare for the approach. Then turn to the downwind side and look for the ALDIS lamp signals from the tower. If you see a lamp signal, acknowledge it by rocking the rotor to confirm you’ve observed it and to communicate your intent to land.
