What squawk code is used for a desire aircraft to assist?

• A. 71
• B. 72
• C. 70
• D. 73

Answer: (B)

Squawk codes are the radar beacon signals that tell ATC what the aircraft’s current situation is. In addition to the well-known emergency, lost-communication, and hijack codes, many training scenarios include a specific code that means the crew is requesting assistance. When the aircraft uses that particular code, ATC immediately understands that help is needed and will kick off the appropriate response—prioritizing the flight, giving guidance, and coordinating any needed services or resources.

The other codes in that same family are used for different statuses, so they would not convey the request for help. Using the assistance-request code makes the pilot’s intent clear to ATC, which is exactly what the scenario is testing.
