AlmoAs we land, we must keep the air speed high enough to prevent stalling. Yet, without an air speed indicator, all we can do is judge the GROUND SPEED, since that is all we have. If, on top of all other problems, there is a severe crosswind and you choose to compensate by making the approach at some angle to the runway, your chances of stalling go thru the roof. Only with a computer can you do the trigonometry calculations required to adjust your air speed, based on the ground speed, to have any chance of making a safe landing.
Very good points. After all these planes fly just like the real ones but are just smaller. I wonder if some of the new fangled radios that have telemetry might some day have speed indicators. That would be interesting if we could actually learn our airspeed in relation to the plane desing when flying RC aircraft. That would introduce a whole new world when landing and could have the potential to give a feeling of flying from the cockpit!
One of the reasons why birds never crash.
