the speed is measured by using primary flight instrument...this instrument have air speed indicator by which v cn measure d speed of airplane..
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.
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)
They are called Supersonic aircraft. Some aircraft can only do that. Some planes have reached even Hypersonic speeds.
No, clock speed is not measured in bytes. Clock speed is a measure of how many cycles a computer's CPU can perform in a second, typically measured in Hertz (Hz) or gigahertz (GHz). Bytes, on the other hand, measure data size or storage capacity.
Generally speaking, a conical shock wave indicates a disturbance(in this case an aircraft) in the air travelling at a speed greater than that of the sound. But this only happens under ideal conditions. Real aircraft have very complex shapes and some part of the aircraft may experience shock wave earlier than the rest (over the bubble canopy or over the wing), so you usually don't get to find a perfect conical shock wave forming around an aircraft in real life.

during flight aircraft reduce speed by spoiler
I think the question is badly phrased, I think it should read:-What kind of Vehicle Speed is measured in Knot's. If Aircraft & the larger water vessels (Ships etc) are defined as Vehicles i.e. that they are capable of carrying goods or passengers then my answer is Aircraft & Ships are defined as travelling in Knot's; in which 1 knot is the equivalent of One Nautical or Aircraft mile of travel.
Its is measured by speed,power,andwind speed
the speed of the engines
The mach number is the speed of an aircraft, expressed as a fraction of the speed of sound in the atmospheric conditions in which the aircraft is flying. An aircraft flying at mach 1 is flying at the speed of sound.
This depends on whether you are looking for aircraft speed limits or motor vehicle speed limits.
its measured in Knots
The cruise speed of the Airbus A320 aircraft is approximately 560 mph.

Ground speed is the speed the aircraft has compared to the ground. This is usually different from air speed, which is the aircraft's speed compared to the surrounding air. Thus an aircraft with 400 kph air speed and 50 kph headwind has a ground speed of 350 kph. For fun: with light aircraft with very low stall speeds it's possible to fly backwards (compared to the ground) if they fly into a headwind that's stronger than their lowest stall speed. I.e. their ground speed is negative.
