The rx was on the boom frequency but not actually joined echelon -therefore he was talking to the PF . Can't think of any other way of putting it sorry.

Not my idea I am afraid.

Alternatively the fighter maintains the control frequency on one radio (for SA on other traffic) and boom on another...

Understood, vasco'.

But surely someone must have thought that it was a good idea? Otherwise why change the tried and tested ways of the past, which worked well?

Nope - one radio for communicating with people (whether tanker or ATC/SOC) outside the fighter formation and the back box for communicating with wingmen inside the fighter formation.

If you need to chatter that much that you are obtrusive on the tanker you are probably doing it wrong. Besides, you can (almost) always use Mids voice....

It's hard not to pass-up the opportunity to criticise the tanker dudes but I am finding it impossible to ignore Typhoon #5's really bad day. Even if the chap was completely tumbleweed he would have remembered that his formation alone was rather large, short of fuel, arriving out-of-sequence and fighting for the illusive VMC. On top of this he had the tanker to join and departing aircraft to consider.

At the point he found himself back in IMC trail, with no SA, talking to nobody but a tanker crew, I just wonder if any of the hairs on the back of his neck were actually serviceable.

Vasco, that is not how the report is written....

THE TYPHOON 5 PILOT reports that he gained visual with the tanker and all aircraft alongside,
began a visual join and switched across [from the join] to the boom frequency. During this process he
lost visual with the tanker as it entered cloud. He descended back to FL240 and ceased overtake
whilst maintaining 2.5nm radar trail. The pilot communicated this to the tanker on the boom frequency
which was acknowledged by the tanker crew, who stated they would commence a climb to FL270 in
Now, this says Typhoon 5 was on boom freq (therefore with the MSO) or, do you know different?

It is not the act of switching to the boom frequency that transfers the control of the receiver ; it is when the rx reaches echelon left that the PF gives control to the MSO. This had not yet happened so I stand by my statement.Your quotation says he maintained 2.5 mile trail-this is very much still in pilot control territory.

Once I'd picked my coffee mug off the carpet, I took a snap of the TCAS for posterity. Just grabbed the camera from it's storage location by the side stick...

AARA 8 is capped at FL 160 as at the eastern end, just east of the CP is a segment of Dutch delegated airspace, base of FL175, so that drives the top of Area 8 as well as Y70 to the south. You can operate higher in coordination with Swanwick, but if the weather is nice, there is no need to get in the way (and Swanwick are already maxed out in this sector, hence the incident).

One does have to wonder WTF is going on these days...

Just tonight the lovely Geraldine announced another 'close encounter' of the military aircraft kind on the local TV news; details are at http://www.airproxboard.org.uk/uploa...%202017029.pdf

The Brize Norton Director vectored the A400(B) into conflict with A400(A).

Contributory:

1. Lack of a formal handover resulted in subsequent assumptions and confusion.

2. The Approach controller’s workload was excessive.

Recommendation: HQ Air Command reviews ATC tasking with regard to current manning at Brize Norton.

@Beagle:
Back in the early 90's a friend of mine died when one P-3 flew into the other P-3, relieving on station, San Diego Op Area, fleet exercise. Two dozen fatalities. Two crews gone. The guys from our squadron who were on the SAR/recovery missions didn't find very much that was very big ...

Back to the original incident.
Mixing traffic operating IFR in VMC with high performance ac operating VFR in VNC is always fraught with difficulty. The fact that AAR 8 is so close to the Norfolk coast is also a factor. There is always a compromise in location of AAR tracks between convenience to receivers and safety.
There is no doubt that the F15 crews should have known AAR 8 was active, however, they were perfectly entitled to be there under see and avoid. Why 4 aircrew, two radars and interrogators failed to see the tanker is of concern?
I find it curious why the tanker pilot turned belly up to the Eagles and therefore losing sight? I’m not convinced that all pilots are trained on collision geometry and how to break a collision. Yes you may break your IRF bubble but at least moving the contacts in the windscreen will avoid metal coming together.
As to later comments in this thread concerning who has control on which frequency when conducting AAR amuses me. This argument has gone on for years and is still not resolved. Since the RAF operates throughout the world the general principle of all doing the same must prevail. I can recall numerous incidents in Bosnia, Kosovo and The Middle East where difference procedures in a multi-national coalition caused confusion. If a very experienced, strong willed individual has an opinion he should write a paper and send it to the appropriate regulating authorities.

Agreed that the F-15s should have awareness of the activity of Area 8, but the report failed to mention that the tankers have no awareness of the bookings for the Wash ATA either. A simple info exchange would solve that. But neither F-15s or tanker received any traffic information on each other from ATC, despite being under traffic information service. See and avoid was in play, and that, plus luck, is what ultimately stopped a collision.

As for why the tanker turned away, consider a pair that you are just visual with. They are in the 10 o'clock low, 5 miles climbing rapidly. TCAS then alerts you to the collision potential due to their rate of climb. Do you turn towards the rapidly blooming aircraft at your max 30 degrees angle of bank? Or away? Or just plough straight on. Tankers are not manoeuvrable especially when the closure is so fast. It takes 5 seconds to action a turn. They definitely can't 'break' to avoid! The tanker turn was initiated as the likely best course of action to avoid the F-15s, in self preservation. The tanker only had time to roll in before the encounter. Monitoring on TCAS and out the window (before the protagonist went under the nose) in the 10 seconds we had failed to mitigate any collision threat. Hence the 'luck' element alluded to in the report.

6foottanker,

You have kind of answered my point. Had the tanker turned left, even a little bit in the time allowed, the F15s would have crossed the nose further away. Its all to do with collision geometry and how to visually recognise and then break a collision.
I am an advocate of TCAS, however, sometimes there is too much reliance on it. Obviously, tanker pilots are used to operating with many "fast movers" operating near to them. There may be an assumption that ALL are visual with the Texaco but this is not always true. Being "heads out" on both sides of the cockpit is still of vital importance.

A turn south would have flown us into the lead (easterly) jet, and you are assuming both F-15s don't change track. They were requested to stop climb as they approached the tanker (and reduced climb rate) so the geometry was against us in each case. A turn away increases the tanker's relative profile to assist visual acquisition and also was auctioned to take the aircraft away from the perceived constant bearing (visually) of the climbing fast jets. However, due to the lack of available response time, the tanker would have been in the same bit of sky whatever they did, once the decision to manoeuvre was made.
But I agree about the TCAS diminishing lookout. Not a factor in this case though since they were seen by me before the TA call.

Stan

[QUOTE=Il Duce;9840837]According to the Tegleraph, a "flight controller" at "Stanwick" was involved. Anyone give a clue to where that is exactly?[/QUOTE

I think you'll find they were talking about Stan Wick who works at Netispaddock.

Wherever that is.

6foottanker, thanks for your reply. Can you tell me what is the maximum bank angle/G that the Voyager is cleared to. Whilst I understand how AT normally operates in Controlled Airspace, a tanker operating in Class G the pilot must be more willing, and able, to operate the ac to it's limits.

Many moons ago I had a similar conversation with Victor crews. Only when they were about to go to war were they interested in how to max perform their aircraft and their StanEval even developed a missile break!!

Oh, that Stan Wick. I thought he'd packed in flight controlling when West Draylon closed. I knew him when he first graduated from Shorbury, I think he got posted to St Athens followed by a tour at Waddingham. Anyhow, good to know he's still guiding the aircraft along the runway with his table tennis bats.

A vital component here is currency.
I am now into my 35th year as an Air Defender and changes over the last 15 years has been dramatic. You can talk all all you like about process and procedure but you cannot teach experience. That comes from hands on practice, and lots of it. In the 80s I could look at a radar picture of the North Sea and it would be chocker with Mil activity. Today (literally), it's like 'Where'e Walt'.
Simulation is the drug of choice and I would say we are at, or close to, an 80/20 split in favour of simulation. Don't get me wrong, the new simulators are excellent but there is no substitute for the real thing.
In the 80s, as an instructor, I could get a student controller at least 2 live sorties a day. A mixture of control levels and a mixture of airspace activity to deal with. Today, 3 a week is considered good but they will do another 7 or so on the simulator so the spread sheet looks good. Once qualified they join a queue as the flying available goes to the students. Skill fade is quick, especially when you add in a 4 month tour in the Falklands not long after qualification. It is a vicious circle.
When it comes to active towlines, and we don't get that many anymore, they are active danger areas and should be treated as such. Irrespective of Radar Service requested in Class G airspace they should be coordinated and restrictions enforced. As a Tanker controller, once I had taken over the joining aircraft and they were 2 way with the Tanker, it was the Tanker Capt who had primacy. Have to admit I am out of the loop a little as to current procedures.
The RAF has shrunk beyond recognition and we are trying to do the same with less. One of the casualties is, and will always be, currency and experience. That is the same, I would say, no matter what your specialisation. The days that ORAC described are well and truly gone.

Dominator, I don't think you will find anyone is likely to talk about specifics. However, you are right that crews should be able to use their aircraft within its limits. The fact is though, an airliner / tanker has very limited max manoeuvrability (in the realms of 50 degrees bank, 20 degrees pitch and +0.5 to +2.0 G). This is very little with which to try and negate a close-in confliction with a dynamic FJ. Coupled with limited flightdeck visibility, the only way to safely operate these large aircraft in the Military FJ environment is to control FJ activity around them.
BTW, the Victor "missile break" would, I think, be a misnomer.
