Imagine that you are a balloon floating around in the air.

Lets say the wind is blowing at 100 miles per hour and you are floating along with the wind.

In this case you will not be travelling any air miles but you will be covering plenty of ground miles.

Because you are not moving through the air.

On the other hand if you are sitting in an airplane that is traveling 100 miles per hour and the wind is blowing at 100 miles per hour. And you are traveling straigh against the wind. Then you will be not be moving from your location and will basically be hovering in place above the spot that you are flying. However you are covering 100 miles of air per hour because you are moving through the air. {1} If TAS + Wd <> 0, AD = (GD x TAS) / (TAS + Wd) {2} If TAS + Wd = 0, AD = infinite AD = Air distance GD = Ground Distance TAS = True Air Speed Wd = Headwind/Tailwind component velocity. >0 if tail wind, <0 if headwind Ground Speed (GS) is equal to TAS+Wd Given a GD to travel: In case (2), GS=0, AD is infinite and you will never get to your destination. If TAS + Wd <0, GS <0 (you go backwards) and you will never get to your destination. In these two cases there is no point in computing air distance.

Yes. An air mile is 6,076.115 feet. A 'land' mile is 5,280 feet.

One Ground Mile = 5280 ft , One Air or Nautical Mile = 6076.115 ft

Cars = ground transportation Airplanes = air transportation

the difference is that one of them is on the ground and one in the air. and one has wings and one doesn't
