Mach refers to the speed of sound. A plane that travels at Mach 2 means that it travels twice the speed of sound in air. The actual speed will vary a bit depending on the altitude.
Mach number is a measure of relative speed. It is the speed of something relative to a medium, usually air, and divided by the speed of sound in that medium: : : is the Mach number : is the velocity of the object relative to the medium used and : is the velocity of sound in the medium Mach number is the number of times the speed of sound an object or a duct, or the fluid medium itself, move relative to each other. It is named afteran Austrian physicist Ernst Mach.

What happens to Critical Mach number with altitude?
Critical Mach Number has nothing (directly) to do with altitude. Mach Number has everything to do Temperature,
How fast in mach 6 in mph?
Mach 6 is about 4,449.3 mph
What is the speed in mph in mach 0.8?
Mach 0.8 = about 593.2 mph
Mach speed is how many miles?
Mach 1 is the speed of sound. 768 miles per hr. Mach 2 is twice that & so on.
What is the highest speed airplane?
If it is civil , its mach 1.- mach 2 ,name is Concorde & in defence they go beyond mach 2
What is the speed of a airiplane?
The speed of a commercial airplane is about 0.8 mach
What is mach in airplane testing?
The "Mach number" is the speed of the aircraft as a percentage of the speed of sound. So an aircraft going at Mach 0.74 is traveling at 74% of the speed of sound. (Mach 0.74 is a typical airliner speed.)
What is the top speed of an airplane with a pilot driving?
Mach 3.5 by SR-71.
What travels faster airplanes or speed of sound?
The speed of sound does not travel. In the event that an airplane's airspeed is below Mach-1, the speed of sound is faster than the speed of the airplane. On the occasion and at the moment when the true indicated airspeed of an airship or an airplane is in excess of Mach-1, the airplane is at that time traveling faster than the speed of sound.
What is a supersonic airplane?
An aircraft that flies faster than Mach 1- or about 770 miles an hour at sea level.
What is critical mach number?
Critical Mach Number, or Mcr, refers to the lowest Mach number that air going over and around an aircraft can reach the speed of sound. If an airplane goes over its Mcr, handling might be greatly affected.
What is the fastest Boeing airplane?
According to Boeing's website, "the 747-400ER is now the largest and fastest commercial airplane in the sky - cruising at Mach 0.85, or 85 percent of the speed of sound."
How fast is a boeing 787?
A Boeing 787 airplane can travel at the top speed of mach 0.89! Mach 0.89=677 mph The Boeing 787 can reach the top speed of 677 miles per hour!
What is the fastest war plane?
The SR-71 recon airplane holds that record. Top speed classified, but admitted as at least mach 3.3, The X-15 rocket plane is the very fastest at Mach 6.6, but was purely a research aircraft.
What altitudes and mach numbers is the yaw damper most critical?
At high speeds and altitudes
In Pokemon how do you get more masterballs?
Go to the department store and mach all of the numbers or cheat for them.
