Tinworm-wings: Disclaimer - Reader Beware!

Disclaimer - Reader Beware!

Remember how I warned that this blog should be read as an account of a student's progress and not as a manual? Well, here's a classic example of why I needed to say that. I got the explanation of the trim adjustment wrong, to the embarrassment of my instructor, Phil. Let's be clear about this, Phil knows his stuff and explains himself clearly. So when there are any glaring errors in my explanations it is just because I have misunderstood something or not yet ironed out the creases. I am on a steep learning curve here, processing loads of new stuff, so there are bound to be lots of glitches along the way.

In explaining trim I referred to the camber of the wing altering. That had been my impression having watched the spar bend, but that was not correct. I am not sure I can quite explain what it does do; I am hesitant to put what I think it does anyway.

So, Reader Beware - this is not a manual. Any errors are mine and mine alone.

Ground handling (how to store an aeroplane at home and get it to the airfield)

A trial flight in a Thruster, when I was 28, c.1991

I have started to learn to fly before...TWICE! First time round I had just graduated and got a job at an aerodrome in Cornwall, where I earned flying hours by fuelling microlights, giving hourly weather reports to the Met office etc. The weather was bad, so there was little flying to be had...and in the end I was paid with broken propellers and bits of crashed fuselage to hang on the wall. The boss was a great bloke called Ian Stokes, who had been a leading light in forming the BMAA and had manufactured Thrusters in the early days . In retirement he moved to The Gambia and became a publican and, shockingly, was murdered this year.

Flying Rogues

ten years on from my first experiences at Moorland Flying School (and now nearly ten years ago) the flying school was under new management and my girlfriend and I booked full courses. We both made good progress initially but never felt we were being moved on and had difficulty pinning the instructor down to signing our logbooks. When another instructor signed himself as P1, we got suspicious, contacted the CAA and were horrified to learn that our instructor did not have a current instructor rating, that we had not been insured and that none of our hours counted towards our licences. We were eventually refunded and the instructors were prosecuted by the CAA.

The very sympathetic CAA investigator spoke to the BMAA on our behalf and my hours have been allowed to count (at the discretion of the school). But in point of fact, I flew way over the minimum number of hours subsequently, so it is really quite academic in the end.

Around 2001 an instructor in Norfolk tried to convince me that if I bought his aeroplane he could teach me at a cut rate, as I'd then be using my own plane. Great idea, I thought, except that it turned out that the aircraft in question had failed a noise test and could not be used from the instructor's field. He later admitted that I would have to learn on his aeroplane at the normal rate. He resisted showing me the paperwork, kept avoiding me and eventually, when it was quite clear I wasn't going to buy without the paperwork, told me to F-off.

So far my experience has been that there are a lot of rogues in flying, which is one reason why I was so very impressed by the professional set-up at Sywell.

by air to Africa

My sister and I were lucky to fly many thousands of miles in the 1960s and '70s in many aircraft types, including BOAC VC-10s, Boeing 707s and even a Nigerian Airways Dakota, as our dad (and later our mum) had teaching posts in Kenya and Nigeria. Those were still the romantic days of flying, when passengers walked across tarmac and up steps, rather than walking down the tubes that have turned passenger flying into a mundane affair. (Mind you, aren't take-offs still incredibly exciting!?)

Back then air hostesses GAVE children the sorts of nick-nacks that their parents have to pay fortunes for from the airline catalogue these days; things like model aeroplanes, keyrings etc. We were also given sweets to help us cope with depressurisation. (And they were hostesses, so nobody give me a hard time)

Mum says that I cracked my first joke when I was small, on a flight out to Kenya, when I said, "Mummy, shouldn't there be a wing on this side of the plane too". Apparently I got her with that one.

At Kano airport I remember standing behind an engine and thinking how hot it still was....and then being told that the engine was cold. The heat was Kano. I got a headache and took several days to aclimatise.

The airport perri-ways at Kano were littered with aircraft that didn't make it, including a burnt-out Mig 15. The Nigerian Airforce flew them and my dad played squash with one of their pilots, Ben, at the Kano Club. I recall a Mig fly-past on my birthday. Was it arranged with Ben over a beer? Was it a pure coincidence?

At Entebbe airport (Uganda) I remember climbing down the steps on to the runway and being encircled by soldiers with machine guns, who then went through all our belongings and confiscated my cherished Swiss Army penknife, purchased on one of numerous European stop-overs. That was in the twitchy time after the Israeli hijacking ...and mum had to stifle my protests.

Before my first flight to Nairobi, as an infant, I was scared stiff. I didn't understand that I wouldn't have to sit astride the fuselage, as I did on my pedalcar! In a funny way, I not only overcame that fear but have come full circle; microlighting is just like sitting on that pedalcar......open to the elements - real flying!

"The elegant solution: the work of Raoul Hafner, pioneer helicopter designer" was the topic of my BA(hons) dissertation. I had met an old lady in a bookshop who saw me showing interest in the aviation section and introduced herself as the widow of Raoul Hafner, who she said had invented the helicopter before the design was ripped off by Igor Sikorski. As it happens, it hadn't been and Hafner himself had never made such a claim, but he did get his first helicopter, the Revoplane 1, airborne in Austria before Sikorski's first helicopter flew. The picture above is not the R1 but an autogyro, the ARIII, which was actually more revolutionary than Cierva's, as it incorporated tie-rods and cyclic and collective pitch control.

Hafner later worked for Bristol Aeroplane company (then based just over the road at Filton, Bristol, where I went to technical college) and designed Britain's first production helicopter, the Sycamore and then the twin rotored Belvedere. I have been a loyal BAC enthusiast ever since.

One wartime design of Hafner's, the Rotachute, a means of dropping an infantryman into battle in a gliding autogyro was subsequently developed by Igor Bensen in the USA, one of which was bought by Wing Commander Ken Wallis (lovely bloke I interviewed for the dissertation), who massively developed it into a powered autogyro.. He built 19 of them in various guises, the most famous of which appeared in You Only Live Twice as Little Nellie, WA116. This short promotional film circa 1984 shows an intended production version.

The good looking young man on the right is my Dad in the late '50s, when he was flying Chipmunks with the Bristol University Air Squadron. I wonder what became of the boys looking out of the windows? Inset you can see him in the early 1960s, just before I was conceived in a powercut.

Dad? He went on to become a schoolmaster and took up gliding when he retired. I am very proud of him: In an air investigation report he was commended for his quick thinking as a novice pilot, after he brought a glider down safely when a fault led to the canopy blowing off.
