What is an airspeed?
An airspeed is the speed at which an aircraft is travelling relative to the air through which it is flying.
How do aircraft measure their speed?
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.
What is groundspeed of the aircraft?
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.
How is the speed of an aircraft measured?
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.
How an airplane floats in the air?
The lift generated by speed of the wing supports an aircraft in the air.
How do you mease speed for helicopters?
You measure forward air speed in the same way you do in any aircraft.
How aircraft speed and altitude can alter air pressure and how it complies with bernoulii's principle?
Aircraft speed and altitude cannot alter air pressure and how it complies with Bernoulli's principle. Aircraft speed decreases the pressure on the wings of the aircraft but this does not alter air pressure.
What is the maximum speed of the air India flight?
It depends on which aircraft is being used.
What is air resistance to the forward motion of an airplane called?
Air resistance to the forward motion of an airplane is commonly known as drag. This force acts in the opposite direction to the motion of the aircraft and must be overcome by the engines to maintain speed and altitude. Streamlining the aircraft's design helps reduce drag and improve fuel efficiency.
What is the difference between true airspeed and groundspeed?
Airspeed is speed with respect to the air, i.e. speed through the air. Groundspeed is speed with respect to the ground, i.e. speed over the ground. It's the vector sum of airspeed and windspeed.
Indicated airspeed compared to ground speed?
Indicated airspeed (IAS) is the speed of an aircraft as shown on its airspeed indicator, which measures the dynamic pressure created by the aircraft moving through the air. Ground speed is the actual speed at which the aircraft is moving over the ground and is affected by wind. The ground speed can be faster or slower than the indicated airspeed depending on the direction and strength of the wind.
How in fighter aircraft is instant pressure difference created for lift?
Flaps are used on aircraft to increase the wing area of the plane and therefore increase lift and reduce speed.
