Madhatter Posted January 10, 2021 Report Share Posted January 10, 2021 Be careful, once again the CT with a static leak will cause a 7 to 10 knot false increase in airspeed. Just putting a wrench on the static fittings is not enough, it can be the EFIS, autopilot, airspeed indicator, etc. I've done hundreds of static checks on all types of aircraft. I've had planes close to stall on approach and yet shown normal airspeed. My CT had a 10 knot false indication when I purchased it from Airtime ( not their fault, it's not a required check for VFR). It's an easy and cheap check to do. Quote Link to comment Share on other sites More sharing options...

Numbers don't really apply. Sub-optimal approach speeds make it impossible without adding power as you can't achieve the landing attitude and instead do something close to the three point landing. The primary reason for presenting this pitch attitude approach is to show how to easily finish/contact in a landing attitude (Vy climb attitude). It also takes away any need for complexity ( 1 speed maintained by trim and 1 config from abeam to ground effect ). Finally it uses optimal approach speed not based on any instrument. Ed, I primarily teach flying by pitch attitude with reference to airspeed. If you know what the sight picture is supposed to be your speed will be just about right.

207WF Posted January 13, 2021 Report Share Posted January 13, 2021 I have two airspeed indicators and I think Tom is right. The two often differ by 10 knots (but they agree at zero). WF Quote Link to comment Share on other sites More sharing options...
AGLyme Posted January 13, 2021 Report Share Posted January 13, 2021 That’s interesting. Folks who land at super slow air speeds are in two groups; the incredibly skilled, and, the folks that need their airspeed gizmos recalibrated. Those of us who are landing fine and want to do better /slower /shorter would be wise to be cautious. Quote Link to comment Share on other sites More sharing options...
