Key Takeaways Mach number is a dimensionless ratio of true airspeed to local speed of sound. Mach number is simply a ratio of your true airspeed to the local speed of sound. Since it’s a ratio, it doesn’t matter if you measure speed in knots, miles per hour, or meters per second. Here’s why. What Is Mach Number?

After a shallow turn from downwind, the Bonanza was positioned on base at a proper altitude and airspeed and with a constant descent rate. The wind at the surface was reported as 220 degrees at 6 knots gusting 19 knots. Increasing true airspeed makes the turn radius wider, resulting in an overshoot.

The right aileron sustained substantial damage. While performing a three-point landing during the rollout the airplane veered left, exited the runway to the left, and ground looped in the counterclockwise direction. During the ground loop, the right wing struck the ground and the airplane came to rest upright on the main landing gear.

Despite the early invention of the aileron, wing warping continued to be used, even on some fighters, as late as 1916. The function of an aileron, or any hinged trailing-edge surface, is commonly explained in ground school by simple analogy to, say, a door opened on a windy day. It affects the entire area ahead of the aileron as well.

In the Cessna 172S Pilot’s Operating Handbook (POH), the landing distance decreases by 10% for every 9 knots of headwind. For the Cessna 172, landing distance increases by 10% for every 2 knots of tailwind. Your aircraft will fly at a faster true airspeed at higher density altitudes.

Pilots must use specific techniques, applying rudder and aileron inputs, to maintain directional control and keep the aircraft aligned. Vf = Vw x cos() The result will give the intensity in knots (KT) and the sign will give the direction: – A positive value indicates headwind (headwind).
