Hi,
Could someone confirm the interpretation I did of this exercise:
(see annexes 071-2084A below)
The inertial navigation system (INS) indicates:
Position: 71° 55.1'N 094°55.3'W
Drift: 6°L (left)
The route followed in order to return to the VOR station is the meridian of the VOR station used:
RESOLUTE BAY (74°43.6'N 094°55.3W), this VOR has North set on the local geographic meridian.
The gyro compass has just been reset to Grid North (chart used: polar stereographic chart, grid parallel to zero meridian, Grid North in the direction of geographic North Pole).
The correct representation of the RMI VOR/DME is at this moment:
(the distance DME is in the box)
---> my interpretation is that I am flying on a True North Track with wind coming from the right. I apply a drift correction angle to the right of 6°. So the arrow of my VOR RMI is pointing towards the VOR station with an angle of 6° to the left of the nose of my aircraft. My True heading is 006° and my Grid heading is 90,27 + 6 = 96,27°
Is that right ? Do you agree ?
The Answer given by "Fly Around" is picture 2 (well,... the pictures don't have numbers) (

Thank you very much for your help and explanation.
