Question:
Which of the following instrument is used to indicate air speed corrected for compressibility effect?
Which of the following instrument is used to indicate air speed corrected for compressibility effect?
Show Hint
Above transonic speeds, compressibility effects make Mach number more useful than IAS.
Updated On: June 02, 2025
- Altimeter
- Gyroscope
- Mach meter
- Pitot probe
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
A Mach meter indicates airspeed as a ratio to the speed of sound, accounting for compressibility effects, especially important at high speeds.
