Refer to figure or to chart E(LO) 2 from the GSPRM 2017.
An aircraft position is (53º40'N, 1º15'W). Determine the aircraft's radials from Manchester (MCT) VOR and Trent (TNT) VOR.

  • A
    MCT: 061, TNT: 020
  • B
    MCT: 065, TNT: 024
  • C
    MCT: 244, TNT: 204
  • D
    MCT: 025, TNT: 063

Refer to figure.
Note: This question would be more expected in General Navigation, however, we believe the following learning objective may be able to cover it and the feedback indicates that it is from FPM. Please let us know if you see it in the exam, and which subject you see it in also, thank you!

Learning Objectives 033.02.01.02: Courses and distances from en-route charts

  • 033.02.01.02.02: Determine bearings and distances of waypoints from radio-navigation aids.

Using the chart, identify the aircraft's position using the coordinate grid. A good method for accuracy is to draw a horizontal and vertical line along the exact latitude and longitude: the location is where they cross.

Then draw lines from MCT and TNT VORs. The radials from these VORs need to be magnetic, so you can either measure the true radial with a protractor lined up against North (then apply the local variation), or you can line the protractor up with the directions of the airways outbound from the VORs.

The true radials outbound from the VORs are MCT: 063º(T), TNT: 022º(T)

Applying the local magnetic variation of 2ºW to both of these (Variation West, Magnetic Best) gives magnetic radials of:

MCT: 065º(M), radial 065.
TNT: 024º(M), radial 024.
