Non-standard touch & go technique.
Whilst in discussion with another instructor (somewhat more experienced than I) recently, he advocated a technique for T&Gs that was new to me. How about this (C152): On base leg, close the throttle and drop 20 flap, speed 65 kts, then trim for this state i.e. the glide. Thereafter add power as necessary to achieve the desired approach path, accepting the out-of-trim forces generated by the addition of power. This means the student will be pushing forward on the column all the way down the approach but as power is reduced in the flare the plane will then be back in trim at touchdown. OK so far? On the roll, full power, carb heat in, FLAPS LEFT AT 20 degrees (or reduced to 20 if 30 has been used), TRIM LEFT AS IT IS, and the takeoff made in this configuration, again entailing a substantial forward pressure on the column, this time in the climbout. The rationale here is that, should the engine fail, you are already set up for the glide and landing.
What surprised me most about all this was that, according to this chap, it is a technique practised by the CFS and if it's good enough for them etc. etc.
I'd welcome opinions, especially from anyone who uses this technique and any CFS or ex-CFS types.
I myself am far (very far actually) from convinced of the wisdom of this method but am open to argument.
What thinkest thou (and does the CFS really do this, and if so why)?
