Refer to Chart "E LO 2" from Jeppesen GSPRM 2017.
Determine the true track and distance from WTD to KER, given:

WATERFORD (WTD) 368 kHz: 52°11'N 007°05'W
KERRY (KER) 334 kHz: 52°11'N 009°32'W
  • A
    266º/94 NM
  • B
    270°/90 NM
  • C
    270°/94 NM
  • D
    273°/90 NM

Refer to figure.
(1) Plot a line connecting WATERFORD to KERRY ;

(2) You can see straight away that WATERFORD and KERRY lie on the same latitude, therefore the True Track from WTD to KER equals 270º;

(3) Determine the distance:

Remember that degrees of latitude are 60 NM apart. Using a ruler, measure the distance corresponding to 1º of latitude on the chart (60NM) and compare that distance to the plotted line length: approx. 90 NM

Note: if you are asked to find the magnetic track, you simply have to subtract or add the variation.
