The speedometer of an aircraft measures air speed - that is, is measures the speed of the air going past the aircraft.
Airspeed is measure in KIAS - Knots-Indicated Airspeed.
There is a method of converting KIAS to true airspeed and ground speed, but, on the subject of ground speed, this is usually done simply by using GPS and LORAN equipment on board, or readings from ground radar units.
The size of tires can effect that accuracy of a speedometer. Larger tires will cause the speedometer to read less than you are actually going.
instantaneous speed. =)
The speed you read from your speedometer is called your "indicated speed." This value represents the speed at which your vehicle's wheels are rotating, not necessarily your true ground speed due to potential inaccuracies in the speedometer reading.
On the speedometer, no. It will indicate a speed but it will not be accurate.
At 60 mph the speedometer will read 58.1 mph.
check if it has a speedometer cable if not the speed sensor needs to be replaced
instantaneous speed
instantanous speed
The speed should read fine with a GM speedometer, as the 110 and 150 are calibrated to go into the same cars with the same transmissions.

If you stay with a 15" wheel these will work pretty well.205/50-15 Speedometer will read 61 at a true 60 mph175/60-15 Speedometer will read 61.6 at a true 60 mph
Any speedometer, on a bicycle, car, boat, or airplane, will read in either kilometers per houror else in miles per hour .
