Question

How is air speed in a glider measured? ?

Answer 1

measured by pitot tube/differential pressure sensor

Answer 2

you know those litle spinny things you see on yachts, the ones that cathch the wind to spin, well thats pretty much how... not the exact same but yeah

Answer 3

Measured by a probe outside the aircraft.

Answer 4

I'm not trying to be smart here, but it's the same as an airplane.  It uses a Pitot tube, which air comes into creating pressure.  That pressure is then sent to an instrument in the cockpit called and airspeed indicator, which translates the electric current into something a pilot reads as airspeed.

Answer 5

the airspeed indicator which measures the difference between static pressure and stagnation pressure due to "ram air", captured through a pitot tube.

Answer 6

A glider has an airspeed indicator just like a powered airplane.  For more information, including pictures and diagrams, do an internet search on "airspeed indicator."
