A co-located VOR/DME is at 66 42'N 043 15'W where magnetic variation is 45W and the transmitter aerial is 500ft amsl. A aircraft flying at FL330 is on the 225 radial and has a DME range of 10nm. its position is:
A. 66 50'N 043 15'W
B. 66 42'N 043 25'W
C. 66 34'N 043 15'W
D. 66 42'N 043 05W
2.
An aircraft is at position 80 N 060W heading 330 (T), groundspeed 500kts; determine the position of the aircraft after 3 hours flying. ( assume a great circle track on a polar stereo chart)
A. 73 00'N 166 30'E
B 72 00N 166 30'W
C. 73 00N 133 30'E
D. 63 00'N 166 30'E
3.
At 1100 UTC an aircraft is estimating arrival at waypoint B at 1400 UTC. The aircraft is at FL310, OAT -50, Mach No 0.82 and wind component -50. it is required to delay the arrival by 10 minutes by reducing speed to Mach. No. 0.75. What is teh latest time for the aircraft to slow down
A. 1212
B. 1225
C. 1250
D. 1300
I am struggling with the 'how to' for the relative velocity questions so explanations and most importantly 'how to' would be greatly appreciated for that question.
Im not sure what im missing with Q.1... the 225 radial bit is confusing me, and the same with Q2 with the 330 (T) part.
Many thanks in advance
