Draw a line to represent the track from WTD to FOY.
Locate the mid-point of the line.
Centre the protractor on the mid-point and align the protractor with True

Measure the track against the edge of the protractor = 286šT.
Measure the distance between the two points with dividers or compasses using
the chart scale or the nearest meridian = 81 NM.
