First draw the route on the chart .... Aberdeen to Benbecular. TOC is at 3W, TOD is at 6W - so now measure the distance of your cruise leg (TOC - TOD).

 

Anyway ..... E(HI)1 ....

 

TOC 3W, TOD 6W .... measure distance = 98nm

Time TOC to TOD (still wind) = 98/210 x 60 = 28mins

Time ADN to BEN 11 + 28 + 15 = 54mins

Time taken = Climb(11mins) + Cruise (dist/speed) + Descent(15mins)
