Malc4D Absolutely spot on. That's exactly how I got a start in this industry.

Not quite right. On p8 under "Other Damage", it says:

Concur with others' comments about the AAIB's impressive ability to produce and release such a clear and readable factual report in a little under a week.

posted by industry insider -

VFR on top (IFR to me) I would have asked for a climb, declared IFR and diverted somewhere with an ILS if necessary, that is if I had taken off in the first place from Redhill into conditions conducive to fog and freezing fog formation.

I would not have been grubbing around at low level over London looking to divert to a postage stamp size VFR heliport which I needed good VMC to get to without knowing the weather at Battersea or between where I was and there. If I need to divert, I will make very sure it is to somewhere I know I can get in. ILS to Gatwick with a visual break to Redhill, or a landing at Gatwick, or Luton / Stanstead, all better than the outcome achieved here.

Me too.

Agree wholeheartedly.

As I sadly reveiw the couple of hundred posts above, half of which are utter BS, I'm prompted to say that most professional pilots have probably been in similar situations. Knowing that things could turn out badly, but through skill and luck, the flight is completed without further event. I,m sorry to see the lastest torrent of "I told him not to go" newspaper articles but that's par for the course. So rest in peace Pete, this flight is over and a new flight has begun.

I find it strange that the report quotes Thames Radar as offering him "VFR if you can or Special VFR" for a transit through the London CTR. VFR is not possible in the London CTR. It's Class A airspace.

Is 'VFR on top' still a legal form of flight in the UK? Thought it had changed some time ago so being unable to see the surface is IMC and therefore IFR flight?

Would anyone else consider the routing/altitudes in Fig 3 normal? R157?

No one so far seems to have picked up on the timing of events around 07.55

5 mins prior to 07.55 Mr Barnes' client phoned Battersea Heliport to see if it was open and was told it was.

at 07.55 Mr Barnes received a text message from his client saying that Battersea was open. It looks like he then radiod to see if Battersea was open (edited - the radio call was 1 minute after 7.55 as pointed out by Ambient sheep in the post #411).

If he chose to divert to Battersea at the specific suggestion of his client then the premise that his diversion was due to weather is incorrect. In fact the report shows he was "safe" VMC on top with a clear stated intention to return to base before 7.55's text and could have accepted an IFR transit offered if this wasn't the case. We also know the pilot couldn't see Battersea when overhead just 10-15 minutes earlier.

The 07.53 text "least we tried" indicated the pilots state of mind to try and do what he could to please the client.

The radio message "IF I COULD HEAD TO BATTERSEA THAT WOULD BE VERY USEFUL" is also interesting. Would "useful" be a word you would use for a weather diversion?


In which case commercial pressures look likely to be the specific reason he was anyway near the impact site in weather that was not VFR (or SVFR) legal.

“ROCKET 2 APPROVED VIA THE LONDON EYE NOT
ABOVE ALTITUDE 1,500 FEET VFR IF YOU CAN OR
SPECIAL VFR, QNH 1012”.

The pilot replied:
“YEAH, WE CAN, 1012 AND NOT ABOVE 1500, VFR
OR SPECIAL VFR ROCKET 2”.

At 0753 hrs,
the controller asked:
“ROCKET 2 DO YOU HAVE VMC OR WOULD YOU
LIKE AN IFR TRANSIT?”

The pilot replied:
“I HAVE GOOD VMC ON TOP HERE, THAT’S FINE,
ROCKET 2”.
So, what was the contract? (S)VFR? Or IFR?

ATC was aware of the wx - temp/dew -5/-5; fog/mist/low stratus etc.

The pilot had clearly stated that he was not in VMC. The oxymoron of "Victor Mike on top" is fully understood.

Why was a VFR or SVFR clearance issued (and accepted) in what was so clearly not VMC?

Sad thing is that it could actually have been Thames Radar trying to help.

readgeoff - yes we see it and you're suggesting that the client was the one who proposed Battersea. Yes, seems like it. But, Barnes would still have to concur (which evidently he did).

As I said (in a much slagged-off) earlier post - pressure to perform?

Well spotted! In fact, the report makes it clear the radio call was at 7.56...

(emphasis mine)

...so it would seem that was indeed the sequence of events after all.

I thought the existing weather at the airfield controlled the status of the airspace and ATC tells the Pilot what that status is by means of the ATC Clearance issued to the Pilot. When does a Pilot get the choice from ATC?

SVFR is already an act of faith from a controller towards a driver.

One question. What is the operators involvement or expected involvment in this?

I see a text at 0640hrs from the pilot to the Operator that says:-

Freezing fog all london airports ok up north have text [client] clearing between 8 - 10


but I don't see anything back.

VMC is defined in the ANO as "weather permitting flight in accordance with the Visual Flight Rules" so is not relevant to this accident because it could not, legally, have been undertaken under the VFR. Only SVFR or IFR were possible. SVFR clearances do not require the aircraft to comply with the VFR - or indeed the IFR. AIP ENR 1.2 contains the slightly ambivalent wording "When operating on a Special VFR clearance, the pilot must comply with ATC instructions and remain at all times in flight conditions which enable him to determine his flight path and to keep clear of obstacles. Therefore, it is implicit in all Special VFR clearances that the aircraft remains clear of cloud and in sight of the surface." However the Rules of the Air Regs Rule (1)(k) clearly states that "special VFR flight means a flight...in the course of which the aircraft complies with any instructions given by that unit and the aircraft remains clear of cloud and with the surface in sight".

I think we can expect some clarification of what SVFR means in the AAIB report's recommendations, as well as such things as whether VMC on top is an acceptable way to transit the London CTR, what clearances ATC can offer into the London CTR, and who decides what the weather conditions are in the London CTR for the purposes of authorising transit clearances (in Class D zones, the ATC unit responsible for the airspace decides what the visibility is. There's no equivalent for the London CTR).

Only in Class D so not applicable here.

I initially thought that was the most important question too but given that the client specifically, twice, advised the pilot not to take off, advice which he rejected, why would the pilot then regard the client's suggestion of Battersea as "commercial pressure"? That could only be the case if the client had said "if you can get into Battersea I'll meet you there". That clearly didn't happen - unless some messages are missing.

PE, you ask about operator involvement.

I would ask who is Witness A?

NS.....who determines if an Airspace is IFR or VFR....each pilot or ATC?

If it is "Controlled Airspace"....some ATC unit has "control" of that airspace.

If no ATC unit has "control" then how does one do SVFR or IFR without an ATC Clearance?

Are we seeing a huge hole in the ATC System around London here?

I only flew over London once....and that was by mistake....amply pointed out to me and my Mate by serious powers that were at Redhill's upper floors. We did not know it was London....but we did know exactly what time it was when we determined where we were....and where we were not.

Read it whatever way you like but for me the accident commenced when the client takes a chill-pill and suggests that PB waits a while. Flip, how many of us have really pushed things because the client is barking at us like a rabid dog? (That Scouse chap who sang a few song in the sixties comes to mind as an example of an excellent pilot succumbing to unnecessary pressure). PB is on the ground at Redhill when This client quite clearly indicates that the weather ain't good and he isn't in a rush. From a charter perspective, things doesn't get any better than that. So why did PB push on and launch despite there being no need?
