Now begs the question....how do these choppers contact a local cop or agency on the scene in a major metropolitan area where the locals are almost always going to be on some sort of 800mhz trunked system which will be different types of systems-talk groups ect...metro county to metro county and city to city? Like...say you have a major air rescue service serving all over metro Atlanta with all of those differing jurisdictions?? I have no idea how on-the-scene comms are handled there.
Being i am a LifeLine Pilot, i can answer this for you.
for all the other services, i cannot answer this. but for my job with Atlanta LifeLine Services i can................
our Radio ops man listens to all the Metro ATL Police/EMS/Fire freqs and then can respond to them with my helo ID and position, then he then talks to me on our inter-job freq. and gives me the freq that the requesting service is using. i then dial in and request a ADF Frequency and status of the situation, where im landing, how far from the actual incident scene the landing site is, what the landing site is and person('s) that im expected to come pickup and of course their status for the EMT guys behind me to listen to and prepare their supplies and equipment. once my ADF Needle is sync'ed and homing in on the beacon, i fly to the scene and report in @ 1 mile out.
