Mach Meter: Measuring True Airspeed in Relation to Speed of Sound
The Mach meter is a device that displays the ratio of an aircraft’s true airspeed to the speed of sound. This instrument is crucial in determining the aircraft’s performance in high altitude and high-speed conditions, where the air density and temperature affect its flight characteristics.
The Mach meter is calibrated to provide the pilot with accurate information on the aircraft’s speed in relation to the speed of sound, which varies with altitude and temperature. When an aircraft reaches the speed of sound, a shock wave forms around it, which causes a significant increase in drag and turbulence, making the aircraft more difficult to control.
The Mach meter helps the pilot to avoid these conditions by indicating the aircraft’s current speed in terms of Mach number, allowing them to adjust the flight parameters and maintain a safe and efficient operation.
With the Mach meter, pilots can optimize the aircraft’s performance and ensure a smooth and stable flight, while avoiding the risks associated with supersonic speeds.
