Avionics Mcqs


Q.  What does Omega and Decca have in common?

a. Both measure the phase difference
b. Both measure the time difference
c. Both measure the power difference
d. Both operate in the same frequency range


ANSWER: See Answer
 
Omega and Decca measure the phase differences between the signals transmitted from pairs of stations while the Loran-C and Chayka measure the time difference between the signal from two or more transmitting stations.
