What is the nominal accuracy of radar altimeters below 100ft?(a) 5 ft(b) 10 ft(c) 20 ft(d) 1.5 ft |
|
Answer» Correct answer is (d) 1.5 ft For explanation I would say: Low range radar altimeters have a nominal accuracy of 1.5 ft below 100ft altitude and 2% of full scale at higher altitude. They have a low noise output that allows the derivation of vertical rate information. |
