Air Traffic control will be problematic as well.

I don't think I've ever seen this many helos in the air at the same time in this area. One of the Helos is using VIPER ECHO 2. Comms are clearer on my Unication G5, but my TRX-1 is scanning multiple towers, unlike the G5, pulling in more traffic.

If you are fortunate enough to be on a mountain or significant hill peak, indeed FRS can be heard at a long distance. The reality is that the overwheming majority of people impacted by this storm are in places other than flat Florida and in deep valleys that are difficult to reach out of with high power radios if there is no repeater on a hill peak. Especially in western NC, Eastern TN and bordering parts of Georgia, Virginia and South Carolina. We know that the majority of those badly affected were in valleys that suffered major flooding.99% of FRS/GMRS radio owners don't use or know of repeaters.
During a previous hurricane here in Central Florida, mostly flat ground, I advised my neighbors via NEXTDOOR to use FRS1 CSQ during the storm. I was surprised how very active it was and the only fly in the ointment that some parents ignored my advice to keep kids from playing on FRS1.
Henderson County NC has a map of families where contacts were made and where none was made. The map is quite evenly dotted, meaning that a family with contact outside could easily make radio contact with ones who have no communications. For whatever reason hiking to those neighbors might be treacherous or impossible.
FRS has indeed been useful in one rescue in Oregon where a hiker was heard 80 miles away by kids playing with FRS radios. The mountains can help, helicopters with radios, even just receivers, can help. I am surprised (maybe not) that the ARRL has not suggested this.
That is why I suggested helicopters as a platform. Most EMS and ENG (News) have Technisonic FM radios that are frequency agile (FPP) in the UHF band.If you are fortunate enough to be on a mountain or significant hill peak, indeed FRS can be heard at a long distance.

Anomalous communications are always possible, but unreliable. The 80 mile FRS contact was likely tropospheric ducting which is very unpredictable and infrequent. Barefoot FRS even the 2 watt channels are not likeky to reach much farther than 2 miles even on flat land where there are still.many obstacles. On the water it could be as much as 10 miles. It may be helpful on flat land if someone is close enough, but in mountainous areas being able to make a contact from where most people live which is not up high, will be somewhat short of a small miracle. It would be worth trying, but not a very reliable means of getting help.

Does anyone know what freqs are being used for NCNG Helo Ops in/around the affected areas? I assume a lot of this traffic in on VIPER but I assume some VHF/UHF Air freqs may be used as well for enroute and normal A/A comms.
Is all the air traffic being managed via the normal ATC outlets or is anyone aware of special air ops freqs in use to help in the coordination?

I've created a Wiki page for Hurricane Helene to start cataloging comms info related to the response. I know for a fact these threads are being used by many public safety agencies to gather info.
Hurricane Helene (2024) - The RadioReference Wiki
wiki.radioreference.com
We've done this in the past for natural disasters and it works quite well to catalog what radio systems and frequencies and talkgroups are in use, and helps with post-mortem of the response.
PLEASE PLEASE help to update this wiki page with info that you gather. Any help adding, formatting, updating info etc will be helpful for everyone involved.
