"The airspeed indicator is especially important for monitoring V-Speeds while operating an aircraft. However, in large aircraft, V-speeds can vary considerably depending on airfield elevation, temperature and aircraft weight. For this reason the coloured ranges found on the ASIs of light aircraft are not used - instead the instrument has a number of moveable pointers known as bugs which may be preset by the pilot to indicate appropriate V-speeds for the current conditions."

Most small aircraft in the US do not have moveable pointers. Indicated stall speed does not vary with altitude and temperature, only weight, and only slightly within the acceptible (certified) range. I think this needs clarification.

Confusion VA vs VNO ?

One of the most important V Speeds that is not marked on airspeed indicators for light aircraft is VA
(maneuvering  speed, the speed at which full and abrupt control movement can be applied without causing structural fuck
damage.

From the V speed page : VNO is the speed at which structural damage can occur, VA being the speed at which stall can occur during sharp turns. So either this sentence is wrong or the V_speeds page isn't very clear--Yitscar 15:04, 22 October 2007 (UTC)[reply]
