I'm a bit baffled by all this discussion. PPL requires 5 hours of instrument flying, does it not? So how can a PPL be unable to use his instruments?

In this case there was no need for risky ad hoc procedures had the aircraft been assisted to reach an airfield where the weather was good. https://www.pprune.org/accidents-clo...l#post11427996 But several people appeared to not read and understand it thoroughly and started a chain of responses irrelevant to what I stated(it does seem to be a trait worth being aware of that there can be a tendency to over-react prior to getting the full amount of easily available information). Ask ATC for weather reports and if within range and doable in vmc, get vectors toward one of those airports for a vmc letdown. It could even be an off-airport landing if necessary. |
There is always this method of course. Well tried and tested, fool proof and never failed. Only in it, for a matter of seconds.
Maybe we could talk Megan into doing the prune test. https://www.facebook.com/reel/127374...?s=yWDuG2&fs=e |
Have done that as well RJ, don't know what point you are trying to make.

Most pilots with a CAP 10 know how to do a spin very well. They usually didn’t buy it for gaining any instrument experience. Got some news for you. Active input for a spin(called holding it on the stops) ain’t that difficult. One should keep in mind is that there are plenty of very good aerobatic pilots with no instrument experience who have done thousands of spins and can actually keep the greasy side up better than you ever could(when appropriate). So yeah, it is quite possible with some pilots. Just do another spin like you did a hundred time previous in your CAP 10 and recover just like you did a hundred times previously. Hmmmm. 421Dog is USA based. Scared of spins are we, after never having been trained how to do one? OMG OMG |

Saying anything else is just wrong. Yeah, aerobatic pilots could probably, but that is not a large group, and you even suggesting it should be tried by the regular flying public is just wrong. Plenty of experience in aviation, never done a spin. The reason the US stopped teaching spins to private pilots was that too many people died getting instruction in how to do them.....
Did I mention in my last post that there is a tendency for people to not read things fully and then respond erroneously? I think I did. Thanks for your analysis that one is more likely to survive an IMC encounter than spin through it...."Full Stop". Show us the data. There is none. As I stated earlier for those not fully reading my posts......"My recommendation just one more idea to have in mind that could work in certain rare cases." This fellow did not encounter that rare case because it was cloudy right to the ground. But his likelihood of surviving the attempt at extended IMC flight for an approach in low IFR conditions was quite low, as it is with a large percentage of VFR pilots that would try such a thing. He didn't even get anywhere close to the low level maneuvering stage for his vectors for the approach. It would appear that some people here seem to think that he had a good chance of survival trying that. I doubt it and would suggest that a large percentage of the GA public have no business getting close to an intentional IMC letdown to a low IFR landing. |

This seems like a situation that could been fairly easy to resolve, depending on the cloud at his high altitude when he called ATC. We know he reported being on top of cloud but cannot be sure if it was a large swath of good VFR on top conditions or not(it would have been nice for the air to get a pirep from the nearby military jet).
The pilot had decent flight experience at over 1000 hours. He also had options with 1.5 hours fuel stated to ATC(and depending on what power setting he based it on, could have been extended). All that need to have been done was to ask ATC about weather reports at nearby airports. There were airports within 1.5 hours that had very nice weather. A request for vectors would get him to a safe airport. Even if an unavoidable cloud layer was encountered, I would suggest that it would likely be safer to penetrate IMC in cruise flight rather than what likely turned out to be a descent at a speed closer to the redline. And even if he ended up out of non-IMC options with low fuel over an airport with an overcast layer combined with a cloud base that was not too low, he could have put his aerobatic plane in a spin and held it there until clear of the clouds, then recovered.

You are wrong. Maybe in some aircraft it would work. But you stating as fact that it will always work is incorrect Still laughing at the mere thought. I challenge Richard to provide a list of types he has tried this in, coupled with video of same. That's the only way he can back up his claim. |
Returning to the original subject of this thread, the fatal crash of G-BXBU, a Mudry Cap 10B, I was shocked to read the Accident Report.
https://assets.publishing.service.go...BXBU_06-23.pdf The Air Traffic Controllers gave the poor pilot no help at all. In fact they made things worse for him, by diverting him to Exeter airport, where weather conditions were completely unsuitable for a VFR landing. This was what the pilot needed, as he was licensed only for single-engine VFR flying, and was stuck above thick clouds at 7500 feet. The diversion was agreed between two "assistants" at Exeter Airport and the Distress & Diversion Cell at Swanick, without a real Controller ever being involved. The pilot had called PAN PAN twice, and was heard by both Control centers, and set his beacon to Squawk 7700. It is confirmed in the Report that any one of these actions should have caused ATC to treat his situation as an Emergency. But the Exeter controller repeatedly referred to G-BXBU as a "weather diversion", then offered an ILS approach !! The controller seemed more concerned that G-BXBU should not conflict with a military jet that was circling, but in no distress at all. No controller ever asked the pilot exactly what his problem was, or established that he had 90 mins of fuel left, so he could divert to several open airports. Finally, the Exeter controller instructed G-BXBU to descend to 2600 feet, which was in thick cloud. The pilot queried this, and the instruction was repeated. The crash followed shortly thereafter. However, it is not possible to say that the instruction caused the crash, as there is some evidence that the pilot had already started to divert to another small airstrip, that was his home base. Look, it must be said that this pilot was performing very poorly under extreme pressure (from his assessment) and he might very well have crashed anyway. Amongst other things, he had been flying with his beacon Off, and had already made several lurid abrupt 360 degree turns, and rapid descents. And he did not communicate very clearly with ATC. He was clearly panicking. But with even average support from ATC, he might have survived, with his passenger. The seven Safety Recommendations in the report all relate to ATC in one form or another. There are none for pilots. I imagine that all pilots would expect that ATC could respond correctly to a call of PAN PAN, and a beacon setting of 7700. Surely ATC must have some statutory responsibilities? Altogether a very disappointing incident. IB |

I agree with everything except the last sentence. And there is not much that could change my mind about that. . I have now publicized a rare but possible exit scenario for someone caught above a layer of clouds that can be kept in mind by people who have read it and passed it along in further discussions. Like I said previously, there are a lot of variables that have to come together including cloud base, aircraft type, remaining fuel, nearby weather, aircraft instrument installation, instrument serviceability, instrument flying experience(or lack of), aerobatic experience, etc to go into the decision-making process. I have anecdotal evidence of it being used successfully at least once. Whether you agree with it is meaningless to me. And I am sure that it will be completely meaningless the erroneous pilot stuck above the clouds in an aircraft without the capability for instrument flight. I could just see the theoretical frantic phone call now from a guy in a Piper Cub stuck above the clouds with little fuel left desperately looking for ideas from a high time guy after making the biggest mistake of his life. He gets admonished to make sure to never do it again and then the phone hangs up with the pilot having learned his lesson. What are you going to tell this guy to save his life?

I'm just a PPL with a long-expired UK IMC rating. I got into cloud before getting the IMC, but did a 180 and got out without losing control.
I have done spinning. Aircraft do not stop descending after spin stops. Nobody has mentioned the risk of pulling high G getting out of the post-spin dive after exiting the cloud and seeing the ground. There is great variation in the height lost in a spin. After spinning initially in Chipmunks I was startled at the height my instructor chose to enter a spin in a Tiger Moth. The parachute video is only relevant if you are wearing a parachute and are current in its use - I've never jumped and would prefer to try to descend on instruments. |

The standard spin risks apply if one chooses to do a spin. As you mentioned, there may be increased risk during recovery due to visual cues. That is why I have mentioned that it is risky, as is the IMC flight option, depending on previous experience and aircraft instrumentation. Mind you, it could be interesting for a low timer to do an instrument approach in your Tiger Moth with a cockpit like this…. www.welovestornoway.com/index.php/articles-auto-3/25264-vintage-visitor-for-stornoway |
I tried the " feet off pedals etc" today in the Bolkow Junior. It worked perfectly in calm air. No tendency to change. I'll try it in turbulence when that's available. Not something I could get the Jodel to do.
Still think holding an aircraft in a spin is dangerous if aircraft was not flown with this intention. C of G will affect characteristics. Spin might flatten. |

Ok.
You have one chance and one chance only. Use the inherent stability of the Aircraft. - Carb Heat on, throttle back to approx 1500 RPM - Trim for approx 70 A/S. Depending on type of course. - FEET OFF THE RUDDERS!! and leave them off! - Ailerons central and keep them central.wheel or stick central. Only instrument needed is ASI Try it for yourself. Sure the aircraft will wallow around etc. but will get you down. DID I SAY FEET OFF THE RUDDERS? Mog |
The only time a Tiger is stable is in a spin - which will get you down through cloud as long as you have enough cloudbase for the subsequent recovery. Only to be used in extremis!! |

..Spin to get out of clouds ??..What could possibly go wrong there..
..Over 3 decades of flying (anything in between ultralights and widebodies), and am still learning new procedures..!! Fly safe, B-757 |
757, is one to assume then that the emergency hands and feet off descent through cloud is well known to you, or one you have yet to learn? ;)

Reading some of your posts on this thread, I have failed to see any constructive input, whatsoever. Maybe you are able to rectify this somewhat. What advice would YOU pass onto a pilot who is caught out, on top of cloud, with one option only, to decend through it? No A/H, no turn and slip? Fair question I believe. |
