Title: Describe procedures to remedy communications failure.
Course: Aircraft Pilot Training I (20053-I) > Section: Exploring Regulations

Description should include the following:

- Ensure the correct frequency has been set and the volume turned up.
- Check to ensure the mic is not stuck.
- Troubleshoot all connections (cords).
- If available, try an alternate frequency (FSS/ARINC). There is almost always a VHF frequency given for every UHF, one of them may not be monitored while the other is.
- There is no order or precedence for trying to contact ATC, including using guard; use all at once if necessary.
- If communications are established with an FSS or ARINC, the pilot should advise that radio communications on the previously assigned frequency has been lost, giving the aircraft's position, altitude, last assigned frequency and then request further clearance from the controlling facility.
- The preceding does not preclude the use of 121.5 MHz. There is no priority on which action should be attempted first.
- If the capability exists, do all at the same time.
- Aeronautical Radio, Incorporated (ARINC) is a commercial communications corporation which designs, constructs, operates, leases or otherwise engages in radio activities serving the aviation community. ARINC has the capability of relaying information to/from ATC facilities throughout the country.
  - Roll back to the last frequency used, if available to test.
  - Attempt another frequency; attempt guard.
  - Utilize VOR frequencies, if able.
  - If unable to re-establish communication with ATC, set the transponder, if equipped, to squawk 7600 for lost communications.
