We’ve decided to call the remake “Reach for the Adnams”. We just need a pretty female as the leading actress – any volunteers?

I think the point is the Yak pilot was doing something different from what he reported on the radio, that’s why nobody spotted him in time.
From a bare accident report it will never be possible to reconstruct what was going through his mind to determine why he acted as he did, especially as he had done a display practice overhead the airfield earlier in the day. The big mistake seems to have been doing his low level pass away from the airfield then trying to climb back to circuit height and the IP towards existing circuit traffic without visual contact. We’ve all been in a normal circuit pattern and heard calls, but have difficulty in spotting exactly where the caller is, even when going in the same direction. With an A/G radio in the UK the operator can’t give instructions, everything is at the pilot’s discretion, so this manoeuvre couldn’t have been prevented.
I’ve had the experience of approaching NW from the east for a crosswind join for 20 with a Jet Provost in the circuit calling “a roller to land”. My understanding of RAF terminology is that a roller is a touch and go landing, so I orbited away from the airfield to allow it time to take off again and get clear of my approach path. It actually did a full stop landing, and I would have had a clear approach crosswind, but I wasn’t preared to risk this.
This is one of the points the report is making about non-standard radio calls. It can create confusion about a pilot’s intentions, and in an Air/Ground radio environment where instructions cannot be given, can lead to fatal results. Where you have a circuit with anything from gliders to fast jets, situational awareness is absolutely vital, and the clear understanding of a pilot’s intentions from radio calls are an important part of this.
The IP for runway 20 at North Weald is a small lake to the north east (just outside the Stansted CTR). From there it is a straight run in clean, not below 500 feet QFE, with a break to the right overhead runway 13/31 climbing to 800 feet to join the circuit downwind. Then you get your gear down, do your checks etc.
There is no suggestion that the Yak had even started his run in. If he had followed his initial stated intentions, and done his RIAB from a right base join ahead of the Cessna, this tragedy would never have happened. The unpredictable extra element sadly led to the deaths of three people. We all make mistakes and errors of judgment, hopefully without fatal results. The important thing is to learn from any accident report and try to ensure it doesn’t happen again.
YR
North Weald can be quite intimidating at times. We have based fast jets including two Hunters, frequent P51 traffic as well as a newly based Spitfire and aerotow gliders flying mirror circuits to the east.
Overhead joins can be a problem because of the 1500 feet base of the Stansted CTA, with the CTR just to the north.
A very busy commercial training airfield at Stapleford Tawney is nearby to the south east, where the circuit pattern is large for noise abatement. And we also have frequent transits by microlights from two local sites. Any arrivals have to keep a very good lookout.
Since the accident they have reviewed procedures, and although RIABs can still be done, there are limitations. For example they are not allowed on Saturdays when a large open air market is held on the site, or when the aeromodellers are flying.
There is a degree of showmanship in doing RIABs, as they are not strictly necessary for energy management. The Yak pilot in the incident cited above clearly showed a lack of judgment. There is a memorial seat outside the Squadron to the two victims from the Cessna as a constant reminder for us to keep a good lookout and not show off.

Sadly true. I got a letter from the council yesterday to this effect, but no explanation as to why it was refused. Finmere has just been sold, but as the buyer owns an Islander, at least he is sympathetic to aviation. We need a few more people like him!

Yes, little inputs on the rudder too – again the yaw will generate a bit of roll. The secret is to make lots of small inputs and anticipate, especially with the throttle.
Also just finger and thumb on the stick (or yoke), otherwise you are too tense and that can generate unwanted inputs on the ailerons too!
When I started training it confused me too. One thing I realised was that you had to be much more aware of the secondary effects of using controls – generating yaw and/or roll.
In a turn, you are still formating, so the picture should be the same for your visual cues on the leader. On the outside you put a fair bit of power on and pull back on the controls; on the inside its power off and push forward. If you use more than the tiniest hint of aileron when you are on the outside, there is a danger that you will start moving in towards the leader as there will be some yaw too from the power changes and as a secondary effect of the roll. Then you may have to roll a bit the other way – and that’s when it all starts going pear shaped.
The problem with loose formations is that the power changes have to be that much greater to maintain position.
That’s why it is so important to have proper training, and not attempt any DIY formations!
I’ve just been checking out the air-to-airs I did recently. That was all done in a rate one left hand turn with me on the outside and I can’t make out any aileron input.
Obviously formation aerobatics require different inputs, but I don’t think Steve had those in mind just yet. And after six hours I’ve still only begun to get the basics.
YR
A few thoughts on this as I was recently involved in an 18-ship Pup and Bulldog formation flypast. They might be of some help.
First point. Formation flying is dangerous, so get some proper training first. Even in a loose formation, when it starts going wrong it can happen very fast. Keep the other aircraft in sight at all times. With a mixture of high and low wing you have different blind spots, your planning should take account of this. Be aware that wingtip vortices and slipstream will throw you out of a formation before you know what?s happened, so never try to overlap wingtips.
Work out a thorough briefing so everyone knows exactly what they are doing and more important, exactly what they need to do if something goes wrong or they have an in-flight emergency or failure. Think about communications ? will they be hand signals or radio. If radio, will you use a discrete frequency?
The flight logistics on our flypast were all worked back from the landing phase, and all the timings worked out to give adequate spacing between aircraft landing. Agree speeds that are comfortable to achieve and allow the wingman some margins. You should have time to do some practice with the actual aircraft beforehand to establish these baselines.
During our run and break, we used a five second interval, but we were allowed three aircraft on the runway at any one time. It is unlikely you would be allowed to do this, so your spacing would have to allow for each aircraft to clear the runway first.
DAs. From what I recall, any formation of more than 3 aircraft requires a specific DA, which is one reason we adopted a Balbo of six Vics with 20-30 second spacing between Vics. You would not be doing a flypast, technically, so the three aircraft rule might not apply. For low performance aircraft use an echelon formation to join the circuit ? with a Vic the leader would have to cross in front of a wingman, which is dangerous. We went from Vics to Echelon left for our RIAB, so breaking right was not a problem.
The slowest aircraft should lead. A Cub is pretty slow, which might cause problems for other aircraft on the inside of any turn, which have to fly even slower. Turns are achieved with use of power and elevator, not aileron (which could roll you into the leader). You are adjusting power settings constantly. Small movements are best otherwise you will be overtaking or falling behind and increasing the workload immensely.
Aircraft may fly in formation, provided the PICs have agreed beforehand. What is not allowed is to formate on someone just because you feel like doing it without prior agreement, as your intentions would not be known.
You?ve also posted these questions on PPRuNe. Do a search for formation flying, there were a couple of threads about this recently.
I think what you are suggesting is perfectly feasible with sufficient training, practice and planning. Good luck!

The Flypast Fly-in is the one this coming Sunday. It has a BoB theme because of the date – see the mag for details.
Access by car is OK any time. If you come on a market day – Saturdays and Bank Holiday Mondays – don’t let the attendants divert you into a parking space, say you are going to the Squadron, and carry on round the peri track behind the market stalls.
Other days, if the barrier is shut at the main gate, again just say you are visiting the Squadron. We often have car clubs ad bikers turning up at weekends to watch the flying. There is a grass viewing area outside the NAAFI with tables. If you want to view aircraft in the revetments or on the flight line, just ask before you do.
The Aces High and Kennet hangars are closed to the public, so don’t try just wandering in if the doors are open!
Give way to any taxying aircraft as you pass live hangars on your way round, and be aware that normal car insurance is void airside (which is past the traffic lights at the threshold of runway 02).
The big apron on the right at the motorway end is where the modellers fly, if that interests you too.
YR
Come this Sunday for the Battling for Britain fly-in. HAC Hurricane is booked to attend. B-25 Grumpy and the Aces High C-47 will be together on static display. The two C-54s are still parked on the Aces High apron. Also hoping for a 72 Squadron Tucano.
Most weekends we have three or four JPs flying, the Gnats often go out too. The newly arrived two-seat Hunter have been flying a fair bit lately as well. And Kennet have lots of other goodies such as the JP1, Hunter, Skyraider, Piston Provost and Wasp, which can also been seen flying now and then.
Peter Teichman is based at NW in his new hangar with P-51 Jumpin Jacques (often flown) and his Staggerwing. Tony Haig Thomas’ Avenger is parked outside and easily viewed, also a T-33 that doesn’t fly.
Loads of Yaks, including several Aerostars.
If you come on a Saturday, be aware that the market traffic on the other side of the airfield can get very congested, some arrive early rather than at lunchtime. Interesting aircraft often fly in for a visit, so you never know what may appear.
Here are some pics of the residents and visitors…
YR
Some more pics courtesy of Mushroom 1. I’ve been given about 80, so here’s a representative selection…
Went today. broken cloud stopped flying until after lunch, then some amazing aeros.
Never seen a ‘handbrake turn’ done in the air before. Didn’t try to take a picture, that’s not the point – just watched the action.
Interesting seeing the way different pilots interpreted the sequences, especially the pentagon loop!
A thoroughly enjoyable day in perfect surroundings – for FREE. And came back down the M11 past Duxford with no traffic jams!
YR
There will should be some air-to-air pics from Sunday morning once I get them from the photographer – probably the weekend. We had our hands full with the flying, so no more from the cockpit I’m afraid! Loads of people taking pics on the ground, so hopefully they will post (big hint Mushroom 1!!!!)

I did think about suggesting it a while ago, as the original plan was to go to Shoreham (where Beagle had a factory) as well. But that fell through because of the air show this weekend.
We’ve got a limited DA, which applies only to North Weald. Next year, you never know! We’ll have had a lot more practice by then, but we’ll probably not assemble so many aircraft until the Beagle Pup and Bulldog Club celebrates its next anniversary. It was the 21st this year – hence the 21 aircraft.
Certainly a nice entry for the Log Book. BTW, our Yak is at Gransden awaiting the paperwork for its annual, so I’m sort of there in spirit! I’m down to ferry it back to Sarfend when its ready.
YR 😀
Can’t make it this year either. I’m taking part in a 21-ship Pup and Bulldog flypast at North Weald on Sunday afternoon.
Great event, well worth supporting. Hope to make it there next year.
YR
Great fun isn’t it! 😀 😀 😀
If your aircraft has a constant speed prop – so you don’t have to adjust the throttle during the manouevre – try holding the stick with both hands. This will neutralise any tendancy to pull towards the hand you are using.
I’ve had the same problem formation flying, with some interesting results. But then I had to keep making small throttle adjustments, so couldn’t use both hands! 😮
YR 😀
