Avionics Mcqs


Q.  Which of the following techniques reduces the diurnal variation but does little effect on the phase behaviour of signal of equal path length over different environments?

a. Composite Omega
b. Propagation corrections
c. PPC
d. Subtracting the signal phases at two of the frequencies


ANSWER: See Answer
 
The composite Omega technique reduces the diurnal variation but does little to reduce the wide variation in phase behaviour exhibited by paths of equal length over substantially electromagnetic/geophysical environments.
