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.

What is the difference between compass bearing and true bearing?
Compass bearing refers to the direction indicated by a compass, typically expressed in degrees from the north, using cardinal directions (e.g., N, E, S, W) or in a clockwise manner from 0° to 360°. True bearing, on the other hand, is measured in degrees from true north, which is the geographic North Pole, and does not account for magnetic declination. While compass bearings can vary due to magnetic variations, true bearings provide a consistent reference based on the Earth's geography. In navigation, true bearings are often preferred for accuracy, especially over long distances.
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.
Is it true or false that when a number is written in word form the decimal point is indicated by the word point?
true
How air speed indicator is modified as mach meter?
An airspeed indicator can be modified into a Mach meter by integrating a pressure sensor that measures static pressure and dynamic pressure to calculate the aircraft's true airspeed. The Mach meter then converts this airspeed into a Mach number, which is the ratio of the aircraft's speed to the speed of sound at the current altitude and temperature. This conversion requires adjustments for variations in air density and temperature, ensuring accurate readings across different flight conditions. Typically, Mach meters have a dial or digital display that shows the Mach number instead of airspeed in knots or miles per hour.
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
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.
What is low speed mach buffet?
There is no such thing as "low speed Mach buffet". It is sometimes confused with stall buffet. Mach buffet is caused by the local airspeed (such as air going around a nacelle or over a wing which is locally faster than the surounding air relative to the aircraft airspeed.) going above the speed of sound and hitting part of the airframe or another area of high speed air from the airframe or nacelle. It occurs usually above .75 Mach or so. Stall buffet is caused by the wing losing lift due to travelling too slowly and requiring an angle of attack that is too high. Stall buffet can be higher airspeed if the aircraft is heavy or under "G" loads greater than 1, in effect requiring a higher angle of attack to maintain altitude. At very high altitudes, it is possible for stall speed and Mach buffet speed to be the same. This is often referred to as the "coffin corner". This is generally at an altitude higher than most aircraft can climb to, so is only a factor in high performance fighters or reconaissance aircraft such as the U-2. This is because Stall Speed is a factor of Calibrated Airspeed, which does not change much with altitude. As altitude is increased, the air density is lower so the aircraft must go faster to maintain a given Calibrated Altitude. True Airspeed ismuch faster at high altitude for a given Calibrated Altitude. Mach number is relatively constant with altitude andvaries with temperature, so the Stall Speed canhave a high True Airspeed at high altitude - and if one goes high enough the Stall Speed and the critical Mach number, where Mach buffet occurs, will be the same True Airspeed. There is no such thing as "low speed mach buffet".
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.
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
