Well said. ?The single most accurate information as to whether the wing will
fly or stall, and tell you best climb, best glide, is Indicated Airspeed. ?

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
Jeff,
I can not honestly say what speed I was doing at your airport for landing. I am
probably a lousy technical pilot as I only glance at the airspeed 2 or 3 times

The ONLY speed the plane knows or is affected by, for purposes of flying,
stalling, control, aerodynamics, is actual AIRSPEED. Period.

John asked about how far the airplane will have traveled down the runway at
different touchdown speeds. The best way to determine that is to find videos
of KRs landing on hard-surfaced runways that have standard runway markings.
Better yet, see if you can find videos that KR pilots may have po

Depending on the wind, but probably about 500 ft. I am off the runway to the
taxiway by 2000 to 2500 ft, no issues. I have neither flaps nor belly board.

Maybe some group somewhere, but not the pilots on KRnet. It's exactly
the opposite. You can get off the ground in probably half the distance
of the landing ground roll. Otherwise we wou

Rob,
This data is very helpful to me, thanks. I see the same thing; especially
pitch stability decreasing rapidly with slower indicated airspeed.
Question: If you cross the numbers @ 80, what distance passes from the
numbers to your touchdown point?

Touchdown should = 1.3xVstall. 52 X 1.3 = 67.6
