I must own up to weighing over fifteen stone. Add a passenger, cameras etc and I sometimes need more of our 450 m strip to get off the ground than I would like.
One measure—I hesitate to call it a technique—I have used is to charge onto the runway, opening up as I turn onto the centreline. Bad practice at a public aerodrome, I would suggest, but the idea is to start the take-off run with some kinetic energy in hand. I wonder if this ploy also avoids anything analogous to the helicopter ring vortex, which may occur when the propeller is running fast at zero groundspeed. (Helicopters lose lift when air recirculates through the rotor.)
Of course, my brilliant reasoning may be nothing but a heap of cack. Anybody able to confirm or counter these thoughts?
