Parachutes everywhere!

I was first to fly in G-CEGL on Saturday so I needed to “burp” the aeroplane! Burping the aeroplane is required as the Rotax engine has a dry sump, so to get oil into the engine and to be able to get a reading of the amount of oil you need to turn the propeller by hand in the correct direction until the engine makes a burping or gurgling sound twice. You can then check the oil level before starting the engine, with our engine and I assume its the same for all Rotax engines of this type, the oil level when cold reads low normally at the bottom of the stick, but once up to temperature  it will read about halfway up.

Mike ask if I wanted to do another hours solo today and I said yes, this time I was to practice flying at different speeds as before, but also steep turns and Mike gave me a briefing on this together with testing me on what to do if I got into a spiral dive. Which was to take the power off and roll the wings level, as the aeroplane levels out the nose will come up and at this point we apply full power and climb away.

I was now ready for my flight, but for the first time Mike was happy for me to go straight off on my own. I sat warming up the aeroplane and was ready to go about the same time as Mick, we had all been using runway 19, but Mick went straight up on the nearest runway 29 and I taxied out to 19, as I was back tracking on 19 I heard the parachute plane call “clear drop” which gives you a few mins and had previously been cited by the parachute plane’s pilot that there is sufficient time for you to line up and take off, which is what I did. How on returning I was advised that in future I should taxi off of the runway and hold clear.

My flight was uneventful but on my return to the airfield I call asking if all canopies where down and it was confirmed, so I called and joined base leg, immediately after my call I hear “Clear Drop” as I was unsure if there was enough time I decided to leave the circuit and hold to the east.

 

Later that day two fellow students achieved their first solo flights, so just a quick shout out to Alan H and Alan B congratulations and well done guys! How was it?

Round and round we go, not in the circuit but advanced turning

Simon and I went over for our lessons together and only just made it there in time due to cars queuing after leaving the car boot sale down the road, note to self to leave a little earlier in future!

On arrival Pete very kindly made us a cup of tea and Simon discussed the lesson he was about to have, “EX 10b – Stalling” with Mike. Pat and Katie went for a fly in Pat’s C42 and shortly after Mike and Simon set off too.

On their return more tea was drunk and Mike produced a large Panettone cake and cut Katie a large slice which she somehow ate!!!

Today, by way of a change and mainly due to the wind direction and gusts we didn’t do circuits in my lesson, I would like to say it was due to me having become proficient in landings, but I’m not there yet! Instead we did “Advanced turning (up to 60° bank angle) – To carry out a coordinated level turn at steep angles of bank and to recognise and recover from a spiral dive” this was both new and fun for me!

We left on runway 24, which was a relief as 29 had been being used, it’s not too bad for taking off, but not the best runway for landing on when you are still learning as it is shorter, narrower and you come in over some power lines. We climbed up to 3,500 feet as we wanted the calm air above the inversion layer, with Peterborough visible in the near distance Mike demonstrated the 45 degree turn and then let me have a go. The 45 degree turn is much like any other turn except you need a bit more back pressure and you need to up the revs a little. I found turning anti clockwise I was losing height and when turning clockwise I was gaining height, this Mike explained, is a common error and is caused by using the nose as a point of reference to the horizon and not where the horizon was on the windscreen, I then tried again and it was much better. Next came the 60 degree turns, wow you can really feel the G force in these turns pulling on your face, its only around 2 G, but you feel it none the less. In these turns it’s principally the same as the 45 degree turns, but it takes more power and considerably more back pressure. On my first attempt I let the nose drop and nearly entered a spiral dive, which is the next part of the lesson! The next attempt went better and on coming out of the turn we felt a bump, which is a good thing, it means we have hit our own wake turbulence meaning we had done a full 360 turn and remained at the correct height.

Next came the spiral dive, this is when you do a 60 degree (or steep) turn and let the nose drop causing the speed to build to dangerous levels, the normal reaction to this is to pull the stick back to reduce the angle of attack and reduce speed, but as you are in a steep turn doing so just tightens the turn and makes it more violent, or at least that was how I perceived it. Mike explained what we need to do is, take the power off and roll the wings level, as the aeroplane levels the nose comes up and at this point we apply full power and climb back to our designated height.

This concluded the lesson, but next was to find the airfield, not a clue had I! What could I see? a town with a prison and railway, well that as it turns out is March, and a gentle turn I spotted Ely cathedral in the distance and the drain below us, from here I knew where we were and flew us back and we joined downwind for runway 24. On final it was a bit hairy with the gusts and I was bit all over the place, but the flare and touch down was quite good especially given the conditions, the only issue I had was Mike telling me to move the stick to the right, well apart from when you are side slipping you move the stick and rudder in the same direction, which I did in an almost automatic fashion and then found we were steering off the runway and I needed to correct it. I was that surprised at my landing in these conditions I found myself asking Mike if he had assisted, but apparently it was all my own work.

 

Mike and I put the C42 in the hanger and returned to the club house for a cup of tea!
