What is the difference between ground distance and air distance?
Because of the difference in the way the two are measured, an air mile is established as a distance of 6,080 feet while a land mile distance is 5,280 feet.
What does air distance mean?
air distance (AD) A distance measured relative to the mass of air through which an aircraft passes. The no-wind distance flown in a given time. Also, it considers the distance increase caused by the altitude above the earth’s surface.
How do you convert air distance to ground distance?
There was a strong linear correlation between ground miles and air miles at virtually all distances studied (R = 0.932, R(2) = 0.869). Regression analysis revealed the following relationship: Ground miles = 0.94 + 1.25 (air miles). This was simplified to an approximation of: Ground miles = 1.3 (air miles).
What is a ground distance?
[′grau̇nd ‚dis·təns] (navigation) The great-circle distance between two ground positions, as contrasted with slant distance or slant range, the straight-line distance between two points. Also known as ground range.
What is the difference between nautical mile and air mile?
A nautical mile measures the same as an air mile, 6,076 feet, or 2,025.3 yards. Though they are the same measurement, nautical miles are used for aquatic travel, and air miles are used only for air travel.
Is air miles the same as road miles?
Guidance: The term “air mile” is internationally defined as a “nautical mile” which is equivalent to 6,076 feet or 1,852 meters. Thus, the 100 air miles are equivalent to 115.08 statute miles or 185.2 kilometers.
How is air distance calculated?
Air distance is the bird fly distance between two locations which is calculated with the great circle formula. nmi: is the symbol of nautical miles in distance calculation.
How many ground miles is 100 air miles?
115.08 statute miles
Guidance: The term “air mile” is internationally defined as a “nautical mile” which is equivalent to 6,076 feet or 1,852 meters. Thus, the 100 air miles are equivalent to 115.08 statute miles or 185.2 kilometers.
What is the difference between air miles and nautical miles?
How do you measure distance on the ground?
If the scale is a verbal statement (i.e. “1 inch equals 1 mile”), determine the distance by simply measuring it with a ruler. For example, if the scale says 1 inch = 1 mile, then for every inch between the two points on the map, the real distance on the ground is that number in miles.
What does the fractional scale 1 10000 map mean?
A map scale might be given in a drawing (a graphic scale), but it usually is given as a fraction or a ratio-1/10,000 or 1:10,000. These “representative fraction” scales mean that one unit of measurement on the map 1 inch or 1 centimeter represents 10,000 of the same units on the ground.
What is an air mile radius?
What is the difference between Air Miles and ground miles?
For an hour flight, your air miles will be 100 nm (TAS) and your ground miles will be 120 (GS). Headwinds or tailwinds affect the groundspeed because the airmass is pushing the plane.
How do you convert AIR MILES to land miles?
You can use standard formulas to compare air miles to land miles. Convert air miles to land miles. The formula is one air mile equals approximately 1.15 land miles. To illustrate, the air mile flying distance between Anchorage, Alaska, and Moscow, Russia, is 3,793 nautical miles.
What is the difference between airspeed and ground distance?
Airspeed would be the speed at which the aircraft is moving through, towards or away from particular parcels of air relative to those parcels. Airspeed is also the speed at which parcels of air are moving towards or away from a particular relative point or object. Ground distance can be measured directly. So can time.
What is an air mile?
The term air mile, also known as a nautical mile, refers to the distance between two locations measured by traveling from one to the other over water or in the air.
