What Is WAAS And How Does It Work In Your Airplane?

A radar altimeter measures altitude more directly, using the time taken for a radio signal to reflect from the surface back to the aircraft. Alternatively, Frequency Modulated Continuous-wave radar can be used. The greater the frequency shift the further the distance travelled. This method can achieve much better accuracy than the pulsed radar for the same outlay and radar altimeters that u… WebWhen near the ground, a special radar unit senses the airplane’s height above ground and indicates it to the pilot. Radar altimeters generally only work below 2,500 feet above ground level. Radar altimeters are expensive and big, so they are usually only found on airliners or big transport-category airplanes. pop sands of time game
