Knot Pitot Tube Stability 
Plane and Pilot
NOVEMBER 10, 2024
In order to be flown by a sport pilot, the resulting airplane must still meet the current regulations—1,320 pounds maximum gross weight, 120 knots max cruise speed, for example—but how it gets there is up to the builder. Airplanes in the LSA category have some performance limitations, so the RV-12 gets right to the 120-knot max cruise figure.

It’s typically measured in knots (nautical miles per hour), with one knot being about 1.15 It works by reading the difference between static pressure and total pressure from air flowing into a pitot tube. Although they each provide specific information, using them together will give you a better picture of your stability.

Air Facts

The general prognosis indicated no icing in the clouds, no turbulence and a quartering headwind from the west resulting in a mere five knots of headwind component. Instead of a gentle breeze out of the west, we had over 20 knots of headwind blowing out of the south. Obviously, the winds aloft were nowhere near forecast.

During the take-off roll, the first officer noticed that although the Challenger 300 was accelerating normally, the right-side primary flight control had stopped showing acceleration above 40 knots. The captain slowed the aircraft from 104 knots and exited the runway onto a taxiway. He called out that he had no airspeed.
