Day 8

Circuit flying today. A circuit is a short flight of between 6 and 10 minutes, comprising a take-off, a sequence of turns all in the same direction, staying close to the airfield, and a landing. It follows a specific pattern (although these can differ at different airfields) and pilots spend a lot of time flying circuits, often one after another in a continuous sortie. You fly one circuit, land, quickly reconfigure the aircraft for take-off while is still rolling along the runway, apply full power and take-off again. Here is an example left-hand circuit (so called because after take-off, you can see that all the turns (on the solid line) are to the left:


The good thing about circuits is that you can practice up to 10 take-offs and landings in an hour. Certainly the Beech Duchess will perform a circuit in around 6 minutes, although the other air traffic at Bournemouth can cause delays to that (at one point today I had to orbit on the downwind leg for about 5 minutes to make way for a 737).

The bad thing is that everything happens quickly, especially in the Beech, and so there is little time to think about or enjoy the experience. I was certainly tired by the end of my circuits today. More tomorrow, this time asymmetric. That's right, flying a circuit with one engine shut down. Does that sound like a good idea?

Unfortunately it is of course very necessary to know how to do that, in case the day comes when it is unavoidable.

Well it sounds exciting to me but I'm just happy keeping my legs on the ground.
Is cold up there or does the plane have heating or is it pure adrenaline.
Sorry we missed your birthday on Tuesday.
Hope it was a good one.
