Already agreed by skyfly150 - who appears to be one of the A/G operators at Seething - and it is noted that his questions were never responded to by the OP...

I do get "touchy" about posters trying to control / moderate the posts of others. We have official moderators for that.
Excuse me for coming back to my earlier posting, but
seems a total contradiction to the "Interpilot" procedures I was taught. Could anyone substantiate the above quote from an official source? Preferrably one not limited to the UK?
as a standard practice you should not assume the right to talk aircraft-to-aircraft on any active frequency

The OP asked about air/air transmissions on an active air/ground frequency, in the UK, with someone operating that frequency on the ground. That was what my earlier "no you shouldn't" post was intended to answer.
JO's post says that my answer
. From that should I infer that those procedures allow a free-for-all exchange pilot to pilot on an active ATS-attended frequency? Surely not.
When a frequency is inactive eg out of hours or simply unattended, UK CAA CAP413 specifically states as below. However, my perhaps heretical view is that CAP413 is a guide to recommended usage, and common-sense should prevail.
At the last CAA-run "Safety" Evening I attended, under the "we want to hear any suggestions that will enhance safety" session at the end, I raised the question of introducing the Unicom-type and Air-toAir frequency procedures that are available in other countries. The CAA man's ever-so-helpful reply was that I should emigrate.

And again: there exists no such thing as an "air/ground frequency". (or it should be another UK peculiarity).

Jan I have no desire to enter in to a fruitless debate with you, because if you seriously believe that pilots are quite entitled to clog up an active ATS frequency with pilot to pilot calls, then nothing I can say is likely to change that.
And just so you know, in the UK there are numerous Air to Ground Radio frequencies allocated. Here is just one of those facilities, extracted from the White Waltham entry in the UK AIP.

Yes there are several stations on 122.60 and Seething is one. We also pay the CAA/Ofcom £650 per annum for the privilege of using it.

I will look up the "Interpilot" section in my ground class syllabus.
As for the A/G: yes, that does seem to be something UK-specific, didn't realise that. But I understand it to be a misleading denomination for a type of service, rather than a property of the frequency.
Agreed that discussion is only useful if aimed at result and consensus.

This thread seems to be drifting around a bit. If it helps, here is a bit of info about the assignment of RTF frequencies. In the UK almost all aircraft service frequency assignments are technically for communication between ground stations and aircraft stations. You will often find this referred to in the rules as air-ground-air or AGA.
Communication directly between aircraft stations is not part of the licence conditions so, technically, except in those situations where we break the rules for safety reasons, pilots should not talk to each other directly.
These licence conditions are largely derived from the International rules set out by the International Telecommunications Union - a United Nations specialised agency for information and communication technologies - which means they should be very similar in almost all countries. However each country has to put the rules into its own law and this introduces differences.
Almost all frequency assignments in the aviation communication band are for air-ground communication. The use of the frequency to provide an air traffic service (ATC or FIS) or the UK's Air Ground Communication Service is authorised under different rules and is associated with specific frequency assignments.
So, the man at Seething was probably technically correct to say that the OP should not have called the other aircraft directly but as many others have pointed out we will have to be sensible about the way frequencies are used.

Mr Cessna,
I'm surprised that the A/G person at Seething made such a fuss of it. However, it isn't "normal" for two aircraft to talk to each other directly on an airfields frequency when the ground radio is manned and operating.
My suggestion in a situation like this is to make a call to the ground station along the lines of
G-XXXX is at (your location). Not visual with the reported traffic, say again his position.
That is then an open invitation for the other aircraft to report his position to the A/G radio unless the A/G replies.
Then you can't be accused of talking directly to the other aircraft but you have achieved your aim.
I do think that radio operators who spend time on the radio telling pilots off are unprofessional. If the pilot is a student, then they are just overloading him/her and a word later on the ground is much better. If it is a qualified pilot then a word afterwards is also much better.
Duxford once spent an age giving me a bollocking on the radio insisting that I did not have PPR. Wasted minutes where no one else could speak.... and they were wrong, they had mislaid the piece of paper. As an inbound pilot all I could do was argue with them while circling or go home.

Well, I did check it, and found that I was mostly wrong. That is to say, my syllabus says - loosely translated:
"Two planes can call one another, at an appropriate frequency, or with the consent of the controller on an air/ground frequency."
So I was right that there does exist a well defined interpilot procedure, according to my text the messages must include the word "interpilot" and also the frequency; but I had forgotten (if I ever learned it properly) that it is subject to controller approval.
I am even more surprised that my text does mention the concept of "an air/ground frequency" which still sounds very queer to me.
I must admit I had it mostly wrong, sincere apologies!

Radio operators
.........The reason I was following up this point is that the person who made the comment 'You are not allowed to talk to another aircraft' shouldnt have been using our ground radio in the first place. ((that's if the transmission wasn't from an aircraft in flight))
There were NO Seething Air Ground operators on the airfield on Monday which was the suggested day of the 'event'. We have a list of 'approved' A/G operators in our club and they are all 'trained to a standard' as laid down in CAP413.
Just unfortunate that I couldnt trace the 'culprit' (in the loosest sense of the word) Perhaps he would have received a RED card.

That's true, in the UK with its particular definition of an "air/ground" frequency. Which I still interpret as "the assigned frequency of an air/ground service".
But I did say it was a loose translation, didn't I? My original says "met toestemming van de verkeersleiding op een lucht/grond frequentie" if that is any help to you. "leiding" translates to "controller" for me, literally it would be "director" or "guide" or "manager".

You know as well as I do that on most days the radio next to the bar at Seething is not manned. It is therefore not uncommon for someone to pick up the handset and try to help out if an a/c calls. Hell - I may have even been of doing it myself - passing r/way in use and wind to the air-amby scooshing through the cct on its way to an RTA on the A143. So on days when the club is not A/G manned then any Tom, Dick or Harry (or Mike, Brian or John) could be sitting having a drink and trying to assist.
Whether that person is A/G trained or just a seasoned PPL is a moot point. MOST of the time the info is pertinent, useful and timely. There are occasions and these might emanate from an a/c in the visual circuit that the RT usage departs from CAP413 and becomes more verbose and conversational in nature. Never seems to happen on busy days but during slack periods.
It's quirky and I for one don't dislike it, I guess that you'd have a problem trying to enforce better RT discipline on most Mondays, Tuesdays, Thursdays, Fridays and Bank Holidays.

There does seem to be a bit much blind, loyal enforcement and adherence to silly rules in some quarters of aviation, and too little rejection of them - driven by licensing and fear, I'd suppose.
It appears from what has been posted here that someone who wasn't qualified to use the radio as an A/G operator may have made the radio call which prompted this thread.

Jan, perhaps in this context, Air-Ground frequency refers to ANY radio frequency used for aviation communications, because "Verkeersleiding" suggests indeed "controller" in the sense of being in charge, and there are no "controllers" on UK A/G frequencies, I believe they are called operators as they are not allowed to control anything.

On two occassions in my career I have been cleared to line up and asked,
"shall I wait for the landing aircraft to land first"?
I have also refused to descend to altitudes below what I considered to be my safety sector altitude on at least two occasions, on one occasion ATC later admitted they had been vectoring the wrong aircraft.
The commander of an aircraft has the ultimate decision on whether to obey any instructions given to him and its this quality that makes a commander, not pedantic hair splitting or point scoring on forums..

Unauthorised use of A/G
Absolutely correct Stiknrudda......A....Yes we all know that does happen and often, and we all know accidents can happen.......there could be serious repercussions if the info given proved to be wrong. We dont want any of that!!
Anyway, the use of A/G radio will all change in the very near future thanks to the dreaded EU. Most likely within a year.
If you want to use A/G you will need a new AGCS licence.
(Air Ground Communication Licence) ((Includes pactical and theory test))
Gone will be the old CA1308 certificate of authorisation!!
I Love to hate the EU.
