2025 Arizona Wildland Fire Aviation Frequency Changes

[es93546]

There have been a few changes to wildland aviation frequencies in Arizona for 2025:

Tucson dispatch has changed all three air to air (AM) frequencies
A/A 1 127.2250
A/A 2 135.2250
A/A 3 121.2250

Williams dispatch changed one
A/A 1 135.3750

Phoenix changed one
A/A 2 124.3750

Flagstaff Dispatch Center changed the order of their air to ground frequencies:
A/G 1 168.7250 (National Air to Ground 57) was air to ground tertiary
A/G 2 166.9625 (National Air to Ground 32) was air to ground primary
A/G 3 168.6625 (National Air to Ground 56) was air to ground secondary

There has been one change to air to ground frequencies for the Springerville Dispatch Center:
A/G 1 166.9000 (National Air to Ground 29) New

I will copy and paste this post to a database change. These are all from a early May document.
EDIT: DB submission just made.

I'm listening to the Carr fire south of Oracle, Tucson District, and they're using 118.425 as Primary AA, haven't seen that one before. 135.225 in use also, was given when the Lead requested a secondary.

Sorry, sounds like they're calling it the Cody Fire today.

The frequency changes I listed are initial attack frequencies. Once the initial attack phase is over when it burns into the second day, it is an extended attack. Other frequencies are used for extended attack. That is likely why 118.425 is in use. Extended attack air to air (AM) frequencies have to be requested through the Southwestern Geographical Area Coordination Center in Albuquerque. AM aviation frequencies are authorized by the FAA. These extended attack frequencies change from year to year.

Thanks, yeah I was wondering why they kept the 118.425 but then the third day (today) switched the secondary to the 128.625. It seems like they are not using the "normally " assigned Tucson Victor frequencies (other than the 135.225) but just going with these random frequencies like 118.425. Back in the day you always pretty much knew where to find the air show, not anymore. Thanks again for all the useful info!
