Hi Mike, How would that help? When landing an aircraft, surely the appropriate reference for airspeed (apart from the feel of the aircraft in flight) is the instruments fitted in the aircraft? IAS is what you'll have in front of you when landing. As long as it's the ASI the aircraft was tested with, and it hasn't changed much since it was tested, inaccuracy due to pitot angle or other causes shouldn't matter. It might be interesting to know (from a comparison with GPS) that the ASI reads low or high or whatever, but will it make landings any safer?
