November 666 Echo X-ray, Do You Read?
(Something from the archives: a 2008 post about Air Traffic Service Units in the UK and my native ability to talk too much. I’ll be back with fresh content next week.)
Air/Ground Radio Airfields with A/G Radio offer an information service with a radio operator who are not licensed and not under close CAA supervision. They identify themselves by saying the airfield name followed by the word radio. It could just be a guy on a mobile radio with no other support. They will offer a basic information service and report known traffic to you.
“Enstone, this is November 666 Echo X-ray.”
No response. I frowned.
“Enstone Radio, this is November 666 Echo X-ray, radio check.”
It had been a chaotic day and we were late leaving. And now that finally everyone was bundled up into the plane and ready to go, the youngster on the radio wasn’t responding. Technically, I didn’t have to request permission to start but it’s generally the polite thing to do. The last time I flew from this airfield, the chap called me just as I was entering the runway to let my know my son had left his bookbag in the cafeteria. Service like that is invaluable and so I didn’t like to risk upsetting anyone but it was frustrating to be sitting here waiting on someone who’d walked away from the mike.
I called a third time, no response. Had he gone for a cup of tea or what? Cliff frowned at me and I shrugged. I decided to try once more. This fourth call elicited a response: a confused voice came back over the radio.
I winced. Who was playing with the radio, for god’s sake? That’s when Cliff’s mum piped up from the backseat.
“I don’t understand why you are saying Enstone Radio,” she said.
I started to snap back an answer when it sunk in. We were at Bembridge on the Isle of Wight. I’d been flying in and out of Enstone the previous week and we’d be landing there today but right now? We weren’t talking to them.
“Bembridge, this is November 666 Echo X-ray, request, uh … geography check.”
I could hear the relieved laughter as he responded. “November 666 Echo X-ray, confirmed, you are parked just outside of my window.”
“Thanks for that. Request start.”
“Nothing to affect,” he told me and we were finally on our way.
Flight Information Service Airfields with FIS are an information air traffic support unit staffed by licensed Flight Information Service Officers. They identify themselves by saying the airfield name followed by the word Information. Their function is to assist pilots to operate safely by offering a traffice service and helping with information regarding weather and aerodrome details.
The tricky thing about Information stations is how they let you know what you should be doing without ever actually telling you what to do.
“Shobdon, this is November 666 Echo X-ray, inbound to you.”
“November 666 Echo X-ray, this is Shobdon Information, go ahead.”
“November 666 Echo X-ray is a PA32 inbound to you, I’m looking to join the circuit downwind for runway 09, right hand.”
The response was immediate. “November 666 Echo X-ray we have three in the circuit, recommend an overhead join.”
I had already descended to 1,300 feet, too low for the manoeuvre that he was referring to, flying over the runway and then descending on the dead side. I also couldn’t see the point, I was perfectly set up to simply turn right and join the circuit in another mile.
He repeated the call. “November 666 Echo X-ray, recommend an overhead join.”
As I continued towards the airfield, I felt frustrated and confused: the advice that the Officer was giving me didn’t make sense. I didn’t like to argue with him, however, and I had to admit it wouldn’t make that much difference to me.
“November 666 Echo X-ray is climbing to 2,300 feet for overhead join.”
A moment later, it suddenly clicked. I was saying Runway 09 but I had been heading for the join for Runway 27, that is, the same runway going the opposite direction. I couldn’t possibly join downwind from my present position which is why he wanted me up and out of the way of his traffic.
I went overhead and joined downwind from a sensible position, much to the relief of Shobdon Information.
Air Traffic Control Airfields with an ATC service have an active control tower staffed by air traffic controllers and are under close CAA supervision. Only ATC are authorised to issue clearances. They identify themselves by saying the airfield name followed by their function (Ground, Tower, Approach, Director, Radar). They offer a variety of services including control, flight information and traffic.
The flight from Guernsey to Alderney was only notable in its simplicity: it took longer to get everyone into the plane than it did to make the journey. Only as we landed did it get hectic.
“Backtrack and exit at Alpha.”
I always feel a faint Top Gun thrill at phrases like that which sound so complicated but I now know are simple. “Wilco” I said with a knowing nod.
Except that having spun the plane around, I couldn’t find Alpha. There was a bit of a turn-in on my right but it disappeared into grass and with the wet weather I was worried about taking a wrong turn and getting stuck in the mud. I grabbed for my plate with a map of the airfield.
“Turn right,” said an impatient voice on the radio. “And expedite, I’ve got another one coming in.” Two planes at the airfield at once, this must be a veritable traffic jam by Alderney standards. I bit my lip and turned the plane right onto the grass and paused.
“Carry on,” said the voice again. “Straight ahead, between the two markers. I take it you’ve never been here before?”
“Affirm,” I said in my best professional pilot voice. Followed by “Sorry,” blowing away any semblance of radio competence.
“Just carry on straight. And expedite!”
Finally the map and the ground in front of me clicked into place, I wondered if the air traffic controller could see the small light bulb appearing over the cockpit as I made my way to the parking area. I had just chosen a nice easy spot to park when the voice came back.
“Pull forward to the blue markers, then face south and then west.”
I frowned as I pulled forward, was he trying to make it difficult?
“Which way is south,” I hissed at Cliff as I fumbled to get the map out again.
“Turn left,” he said. I turned then tried to picture a map in my head. If I am facing south then I’m looking towards Texas. California is west and on my right. Got it! I opened my eyes and looked around. “So west is to the right now, right?”
Cliff sighed at me. “Just use the Directional Indicator?”
I blushed and turned the plane until the DI pointed west.
“Just park there,” said the voice. The other plane had landed and radio silence descended. It would probably be at least an hour before they see any further traffic. I shut the engine down.
Military Air Traffic Zones It goes without saying that you should be unfailingly polite to any controller who has fighter jets to back him up. In the UK, the pilot should contact the controller either 15 nautical miles or 5 minutes flying time from a military boundary, whichever is sooner, requesting penetration. To enter the central area (Aerodrome Traffic Zone) you must receive permission and comply with the controller’s instructions.
My first run-in with the military was actually in France.
We had landed at an airfield for refuelling but they were having technical difficulties and informed us that they would not be able to offer fuel for the rest of the day. A quick glance at book showed us another airfield on route that listed AVGAS 100L and so we jumped into the plane and went straight there, plotting the route as we went.
“Cognac, this is November 666 Echo X-ray.”
“November 666 Echo X-ray, pass your message.”
“November 666 Echo X-ray is a PA32 inbound to you, currently 20 miles to your NW at 4,000 feet, request airfield information and joining instructions.”
There was a brief pause.
“November 666 Echo X-ray can you state your intentions.”
“We’re inbound to you for refuelling.”
“November 666 Echo X-ray are you aware that this is a military airfield?”
“Oh. Uh, no. Negative. I was not aware.”
“November 666 Echo X-ray I say again, can you state your intentions?”
I bit my lip but silence seemed likely to get a missile aimed in my direction.
“Er, I intend to ask your advice on where we could go for refuelling in the local area?”
The controller was perfectly friendly about it, verifying that I was not in an emergency before recommending that I fly direct to Angouleme and even offering me a heading and a flight information service directly to the airfield. Anything, I guess, to keep me out of his zone.
Using the radio professionally has become an essential requirement in the modern aviation environment. Radio provides the interface between you and others, especially the Air Traffic Service Unit (ATSU) whose frequency you are using. You will make life more comfortable for yourself (and others) if you can use the radio efficiently.
When I first started my PPL, I was told that I had a real knack for using the radio. Getting my radio licence was the easiest part of the entire training. Little did I know that in the meantime, I would manage to mess up speaking to every different type of Air Traffic Service Unit in existence.
