Mach Number Explained: What It Is and Why Pilots Use It

Pilot Institute

Since it’s a ratio, it doesn’t matter if you measure speed in knots, miles per hour, or meters per second. At sea level on a standard day (15 °C or 59 °F), sound travels about 661 knots (approximately 761 mph or 1,225 km/h). Here, Mach 1 is roughly 573 knots (about 659 mph). on dry thrust alone.

Everything You Need To Know About Ailerons

Pilot Institute

The asymmetry between the top and bottom surface of the wing is called wing camber. The downward movement of the aileron increases the asymmetry and, therefore, the camber while raising the aileron reduces the wing camber. They can use the engines to produce differential thrust to steer the aircraft. What Is Aileron Trim?
