Talk:Ground speed

From Wikipedia, the free encyclopedia

I Changed "over the ground" to "relative to the ground". This makes it obvious that it is the speed of the airplane that is measured against the ground, as opposed to it possibly meaning that the airplane itself is over the ground at the time you measure its speed. 212.138.64.171 16:45, 13 December 2005 (UTC)

[edit] merger proposal

Ground speed is not an airspeed; it is a vehicle's speed over the ground rather than through the air (a medium which can itself be moving). They're totally different concepts, and it wouldn't make any sense at all to merge them. ericg ✈ 04:05, 23 October 2006 (UTC)
