Question on Frequency allocation.

.

* This is not something I need to do, just a query *

How are comms frequencies are allocated to airfields which don’t normally have the need for them.

For instance, if a small airfield is having a fly-in, and needs some sort of comms, air to ground, and air to air.

Would a temporary frequency be allocated, which would not interfere with any other airfield in that particular part of the country ?

Who would allocate that frequency, CAA ?

I also assume there would be restrictions as to power output from the ground station ?

I’m afraid so. It certainly is a frequency that is allocated to others, though at this time I can’t remember to whom.

Though for some obscure reason, probably liability-related, the powers that be discourage this.

Maybe (as you say) if the info is incorrect and there is an accident, it leaves them wide open ?

Thanks for the additional info.

Just to add: I know some pilots, both commercial and private, use 123.450Mhz as an air to air comms link, although
I believe this is unofficial, and no doubt breaking the laws of aviation ?

Someone might answer, giving you the runway and the QFE.

Or you can hire sometime poster here, Steve le Vien, to handle your comms for you. He’s a proper, trained air traffic controller of a zillion years’ experience. A discrete frequency for an event is allocated by NATS rather than the CAA if I’m not mistaken, but they’ll want somebody proficient on the other end of of the mike.

He frequently runs the comms at Old Warden displays, and handled Abingdon this year.

In the absence of an established frequency you would normally communicate on Safety com; 135.475 blind calling the airfield. For example: “Blogsfield traffic, inbound to you from the South with ten miles to run”.

Someone might answer, giving you the runway and the QFE.
