Refer to chart E(LO)2 from Jeppesen GSPRM 2017.
Given the following bearing and range information obtained from POLE HILL (POL) VOR/DME (53°45'N, 002°06'W), what is the aircraft's position?

Radial: 017°
Range: 85 NM
Slant range corrections should be ignored.

  • A
    53°42'N, 001°38'W
  • B
    55°06'N, 001°27'W
  • C
    55°07'N, 001°40'W
  • D
    53°42'N, 001°18'W

Refer to figures.

Radial:17˚
Variation: 2˚ W
True track: 15˚

Cos 15 = Z / 85
Z = 85 x cos 15
Z = 82.1 NM

Difference in latitude = 82.1 / 60 = 1˚22’
New latitude = 53˚45’N + 1˚22’ = 55˚07’

Sin 15 = Y / 85
Y = Sin 15 x 85
Y = 22 NM

One degree latitude at 55˚07’ equal

Cos 55˚07’ x 60 = 34.3 NM

New longitude =002˚06’ — (22/34.1) = 1˚27’

Aircraft position: 55˚07’N, 001˚27W
Closest Answer: 55˚06’N, 001˚27’W
