Does airspeed increase with headwind?
A headwind will cause groundspeed to decrease. A tailwind will cause it to increase. Neither of these, however, has any effect on airspeed. The speed sensed by the airplane — the air moving over the wings — has no bearing on how fast it is moving relative to the ground.
What is the difference between GS and TAS?
3 Answers. TAS = True Airspeed = speed that you get on radar gun as airplane flies by, when radar gun is held by someone in gondola of balloon in same airmass (wind motion) as airplane. GS =Groundspeed = speed that you get on radar gun as airplane flies by, when radar gun is held by someone on ground.
How do you calculate true airspeed?
Read your altitude above Mean Sea Level (MSL) on your altimeter, based on the proper altimeter setting. Mathematically increase your indicated airspeed (IAS) by 2% per thousand feet of altitude to obtain the true airspeed (TAS). For example, the indicated airspeed (IAS) of my Comanche at 8,500 ft. MSL is 170 knots.
What is vertical speed in aviation?
Vertical airspeed is the rate at which an airplane ascends or descends. It is different from ground speed. More specifically, the rate of climb tracks the airplane’s vertical airspeed, and the rate of descent, or sink rate, is how quickly the airplane is descending.

What is QNH?
Regional or airfield pressure setting (QNH) is set when flying by reference to altitude above mean sea level below the transition level; Height. Altimeter pressure setting indicating height above airfield or touchdown (QFE) is set when approaching to land at airfield where this procedure is in use.
What is calibrated altitude?
Calibrated altitude is corrected for nonstandard atmospheric conditions. It is the actual height above mean sea level, as if measured with a tape measure. Elevations of airports, mountaintops, towers and other obstructions are given in true altitude.
How accurate are altimeters?
The general rule of the thumb is that vertical error is three times the horizontal error. If a decent signal reception is available, a modern GPS receiver should be able to give elevation data accurate to a range of 10 to 20 meters (35 to 70 feet) post correction.
