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
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
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.
The arrowhead of a compass always point north?
True north is the direction indicated by the Earth's axis of rotation, while magnetic north is the direction indicated by the compass needle. The arrowhead of a compass points towards magnetic north, not true north.
What is function in MSEXCEL?
They are pre programmed commands (functions) that the user needs to make operational demands on the spreadsheet. i.e. DAY Converts a serial number to a day of the month DAYS360 Calculates the number of days between two dates based on a 360-day year EDATE Returns the serial number of the date that is the indicated number of months before or after the start date AND Returns TRUE if all of its arguments are TRUE FALSE Returns the logical value FALSE IF Specifies a logical test to perform NOT Reverses the logic of its argument OR Returns TRUE if any argument is TRUE TRUE Returns the logical value TRUE
Is it true that The difference of two rational numbers always a rational number?
Yes. The rational numbers are a closed set with respect to subtraction.
