In "percent of maximum." A turbine engine's compressor shaft rotates at a very high speed - 20,000 to 30,000 rpm. Let's say your engines run at 25,000 rpm. Pilots don't want to have to do math if they want to slow the engine from 100 percent to 75 percent, they just want to slow the plane down...so the tach is marked in percentage of maximum rotation speed.
The speed of an aircraft is measured using an airspeed indicator, which measures the speed at which the aircraft is moving through the air. Groundspeed, on the other hand, is the speed at which the aircraft is moving over the ground and is measured using GPS technology.
Aircraft measure two kinds of speed, air speed and speed over ground. Air speed is measured by the flow of air one way or another. Speed over ground can nowadays easily be measured by GPS. Or the Old fashioned way of checking the time it takes to pass from one land mark to another.
It works the same way a car tach works. It measures engine revolutions electrically from the coil/distributor or from a crankshaft sensor that is usually magnetic. On jet engines it is measured from the constant speed drive and is measured in percent of total power available rather than rpms.
The speed is messured in knotsAirspeed in measured in Knots. It is generally measured by a small intake on the aircraft that measures the speed that air enters at. This measurement is know as indicated airspeed. The thing to remember is that indicated airspeed differs from ground speed as it takes into account wind speed. For example, an aircraft is flying at 110knots ground speed into a 10knot wind so it's indicated airspeed would be 120knots (110+10)
In aviation, 'V2' speed refers to the takeoff safety speed. It is the minimum speed at which an aircraft can safely continue a takeoff in the event of an engine failure. Pilots use V2 speed as a reference point during the takeoff phase to ensure the aircraft has enough performance to safely climb and maneuver.

This controls the engine speed

There is no speed limit, aircraft have differant take-off speeds called V1 - is the critical engine failure recognition speed or takeoff decision speed. It is the decision speed nominated by the pilot which satisfies all safety rules, and above which the takeoff will continue even if an engine fails. The speed will vary between aircraft types and also due to aircraft weight, runway length, wing flap setting, engine thrust used, runway surface contamination and other factors V 2 - Takeoff safety speed. The speed at which the aircraft may safely become airborne with one engine inoperative. -Wikipedia
By adding thrust to the engine or pitching downwards
To increase the speed of the engine, which is measured in 'revolutions per minute' - shortened to RPM or 'revs'.

Jaguar XKR 2002 has a V8 4.0 litre engine with double compressors which produces 370 BHP. Its limited to 250 kph.
It's the takeoff safety speed. The speed at which the aircraft may safely become airborne with one engine inoperative.
As fast as it can. There are no speed limits in place for aircraft. However airlines limits speed for economic reasons. Also the way the engine is designed affects speed. The faster the engine is going, the hotter the engine will be. The turbines get the worst of this heat and if it gets to hot the turbine will fail. And the economic reason being the faster the aircraft, the more fuel you need. The Concorde was a supersonic aircraft. How ever it burned way to much fuel and that proved way to costly to operate the craft.
