Question

The guidance sensitivity decreases as the range decreases

(a) True

(b) False

This question was posed to me by my college professor while I was bunking the class.

My question is from ILS/MLS Coupled Landing System and Automatic Landing in division Autopilots and Flight Management Systems of Avionics

Answer 1

Correct choice is (b) False

The best I can explain: The beam error of a localizer or glide path transmitter is given by γ =d/R, Where R is the slant range of the aircraft. It is evident that the beam error is inversely proportional to the slant range. As range increases, beam error decreases and hence the guidance sensitivity is more.
