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.
A number that makes an equation true is its solution.
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
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.
They equal 180 degrees.
true
No. The difference of +7 and -1 is 8 .
True.
Yes, that's true.
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
TRUE
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
It's not true. 500 could round to 1000. 1499 could as well. Their difference is greater than 499.
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".
Yes. The rational numbers are a closed set with respect to subtraction.
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
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.
