AIM Text
- In addition to monitoring the NAVAID voice feature, the pilot should attempt to reestablish communications by attempting contact:
- On the previously assigned frequency; or
- With an FSS or with New York Radio or San Francisco Radio.
- If communications are established with an FSS or New York Radio or San Francisco Radio, the pilot should advise that radio communications on the previously assigned frequency have 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.

The short answer
This AIM section is FAA advisory guidance on reestablishing radio contact after a communications failure. Beyond monitoring the NAVAID voice feature, it advises the pilot to try the previously assigned frequency, or an FSS, New York Radio, or San Francisco Radio, then report position, altitude, and last assigned frequency and request further clearance — supporting lost-communications procedures under 14 CFR 91.185.
Research Notes
Common Questions
What should I do to reestablish radio contact after losing comms?
Per this advisory section, in addition to monitoring the NAVAID voice feature, the pilot should attempt contact on the previously assigned frequency, or with an FSS or with New York Radio or San Francisco Radio. The guidance notes this does not preclude using 121.5 MHz, and if the capability exists, all actions may be attempted at the same time.
What information should I pass once contact is reestablished?
If communications are established with an FSS or New York Radio or San Francisco Radio, the AIM advises the pilot to report that radio communications on the previously assigned frequency have been lost, give the aircraft’s position, altitude, and last assigned frequency, and then request further clearance from the controlling facility.
What are New York Radio and San Francisco Radio?
The section notes that New York Radio and San Francisco Radio are operated by Collins Aerospace, Incorporated (formerly ARINC) under contract with the FAA for communications services, and these facilities can relay information to and from ATC facilities throughout the country.
