But I still reckon you can't do a point and power with your pitot system shagged.
So you are trying to tell us that it is impossible to fly straight and level at a constant speed with a failed pitot?
i.e. you can not make the trajectory of the aircraft horizontal (point it at the horizon) and set cruise power?
or that you can not fly a 3 degree approach slope in the landing configuration and appropriate power set?
Aircraft A comes down the glide at 90Kt with gear down, land flap and x power. Why if I point the aircraft down the 3 degree slope (visual or ILS it makes no difference) have the correct configuration and the correct power will the speed not be 90Kt or very close to it?
Point and power does not mean chase the airspeed.
People who can fly accurately will require very small corrections and therefore will not have any significant airspeed deviations cause by large corrections which in turn are cause by not being able to recognise the constant point and keep it where it is supposed to be.
