Indicated Mach number which is corrected for instrument and position errors equals True Mach Number
Instrument errors are errors due to manufacturing or design defects that all instruments have to some small degree.
Position error is due to the position of the pitot and static ports on the aircraft getting disturbed air pressure from some part of the aircraft's structure.

Number that makes an equation true?
A number that makes an equation true is its solution.
How would you explain to someone who has not yet studied trigonometry the difference between an identity and an equation?
An identity is true for all values of the variable whereas an equation is true for only a finite number of values.For example,Identity: (x + 2)3 = x3 + 6x2 + 12x + 27 is true, whatever the value of x.ButEquation: x3 - x = 0 is true only when x = -1, 0 or 1.
True or false The standard abbreviation for height is h?
True
What is a true bearing?
A true bearing is a type of bearing that indicates the direction of one point relative to another point on the Earth's surface, measured using true north as a reference point. It is expressed as an angle, measured in degrees, between a fixed reference direction (such as true north) and the direction of the point being observed. True bearings are important for navigation, surveying, and other applications that require accurate direction-finding. They differ from magnetic bearings, which are measured relative to the Earth's magnetic field, and are subject to variation depending on the location and time. True bearings are more reliable and consistent, as they are based on the Earth's axis of rotation and do not change over time or location.
What is true about the sum of the angles in any triangle?
They equal 180 degrees.
Is it true or false that when a number is written in word form the decimal point is indicated by the word point?
true
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.
Is it true that the difference of two numbers is less then the greater number?
No. The difference of +7 and -1 is 8 .
The difference between two whole numbers is always a whole number?
True.
Will the speed of an aeroplane be same which is flying at different altitudes and have same mach number 2?
no mach no is defined as ratio of local speed of aeroplane to speed of sound. As the altitude increases the True speed of aeroplane increases and speed of sound decreases because of reduction of ambient temperature Hence the value of their ratio should increase at an increasing rate with increase in altitude. Keeping the Mach No constant say, 2 means reduction of speed to a large extent so as to maintain constant Mach No. Therefore same Mach no the aeroplane at higher altitude is flying slower
The difference of two rational numbers is always a rational number?
Yes, that's true.
Is thermal efficiency is the ratio of indicated work done to energy supplied by the fuel true or false?
TRUE
Define dynamic error?
dynamic error is caused by time variation in the measured quantity
Different magnetic deviation and magnetic variation?
In relation to aviation... Deviation is the difference between a true heading and the compass heading. The compass heading is different from true due to magnetic fields induced by the components of the aircraft. Variation is the difference (angle) between True North and Magnetic North. Variation changes depending on your position and is normally indicated on maps as a dashed line with the variation in degrees along that particular line.
What is the difference between superstition and faith?
A superstition is more of a myth that many people are thought to believe but may not be true. A faith is a belief that a number of people believe that is true
What is low speed mach buffet?
Low speed mach buffet is a term used in aviation to describe the buffet or vibration that occurs on an aircraft as it approaches the critical mach number at low speeds. The critical mach number is the speed at which the airflow over the wings reaches the speed of sound, causing a shock wave to form and disrupt the airflow over the wings. When an aircraft approaches the critical mach number at low speeds, such as during takeoff or landing, it may experience buffet or vibrations as the airflow becomes turbulent and begins to separate from the wings. This can cause a decrease in lift and an increase in drag, making it more difficult for the aircraft to maintain control. Pilots are trained to recognize and respond to low speed mach buffet by adjusting their speed and angle of attack to prevent the aircraft from entering an aerodynamic stall. By understanding the effects of low speed mach buffet and how to mitigate them, pilots can safely operate aircraft at low speeds without compromising performance or safety.
Is it true that if two number both round to 1000 as their nearest thousand the greatest possible difference between them is 499 explain the answer?
It's not true. 500 could round to 1000. 1499 could as well. Their difference is greater than 499.
