During interception, what frequency is typically used to contact air traffic control after squawking 7700?

• A. 121.5
• B. 122.0
• C. 123.0
• D. 124.3

Answer: (A)

In an airborne emergency, the priority is to establish reliable contact with air traffic control using a channel designated for distress coordination. The frequency commonly used to reach ATC after squawking 7700 is 121.5 MHz. This emergency/guard frequency is specifically set aside for distress calls and coordination with controllers and other aircraft when normal communications are compromised. It’s monitored for urgent situations, making it the best choice for initiating contact after declaring an emergency. The other frequencies listed are regular VHF channels used for routine flight communications and aren’t the standard emergency contact channel in this scenario.
