Flying the Tecnam P92 Echo and Old Wives Tales

[markkal]

This is nothing new, and aerodynamically speaking it has the same effect as pushing on the stick in a taildragger on the takeof roll to ease the tailwheel of the ground.
I both cases (Tecnam and a tailwheel, say a PA18) it gives an incidence to the wings which let them acquire lift as soon as the airflow rises and then the aircraft will take off by itself as soon as it reaches 1,1 Vs. And this eases the strain on the nosewheel of the Tecnam (Or the tailwheel of a Piper), which are both quite flimsy and prone to damage.

However, this technique must be done with a very light touch on the stick, and for any front wheel aircraft it has to be raised just a tiny bit (approx 3 to 5 degrees) of incidence.
Given the low power of a basic trainer, it is essential, and nobody seems to have mentionned it here, just after liftoff the sick must be eased forward to reduce drag and allow the aircraft to accelerate well above 1,1 Vs.

There is a big risk if this is not done to remain in the back side of the power curve or second regime.. And yes it is not advisable in a cross wind, definitely not with a right turn propeller with wind coming from the left, due to torque effects, but both from the left or the right as the cross wind carries a forward component and is often not linear but turbulent and 1,1 Vs liftoff speed does not carry a margin for safety.

Taking off from a grass strip also reduces ground friction drag as you will have one less wheel rolling.

Off topic, I would ad on landing the pleasant sight and finesse of pilots touching down on the mains and holding up the front wheel til lift loss eases it down to the ground like a feather..
An art today lost where aircraft are often slammed to the ground with no control after the flare, plus that nose drift due to uncorrected parallax, that" screech" noise which in addition to not being very elegant imposes torsion. Those old built like tanks Cessna's and Pipers will tolerate that, but today's light and flimsier built aircraft derived from ultralight desing will but if abused will eventually fail.
