Subject: Airtanker Base Frequency Change 2014
Area of Concern: All Aviation Users
Discussion: The FAA reviews and engineers all aviation Air-to-Air AM frequencies for all Airtanker Bases
each year. Usually, the frequency 123.975 MHz is assigned for this purpose. However, if the frequency is
not available at a given location, the FAA will engineer an alternative frequency. Due to engineering
restrictions there are several new frequency assignments/changes to the National Airtanker Bases
frequencies for fire season 2014. While most bases retain 123.975 as the RAMP frequency, notable changes
are highlighted in red. These changes are effective immediately.
