Help please
Hi everybody,
here is a question i struggle to answer even if i'm sure it's really easy to answer.
here it is :
The Average magnetic course from A (64°N 006°E) to C (62°N 020°W) is :
a) 271
b) 259
c) 247
d) 279
answer a is correct
Could someone remind me (if i ever forgot) how do we calculate this? I'd be tempted to look on a chart to get the answer but i'm sure there's a way to calculate it and that the question expects us to do so (rather than simply plotting a track on a chart).
Sorry if my english is not perfect
many thanks

plotting
Is this from Flight Planning on the NAP chart? Sounds vaguely familiar,
You'll need to plot it. Mark your two points, draw line joining them and then use your plotter at a point in the middle of your line as you're asked for the average track. Then correct for your magnetic variation at that half way point as well.
If I remember correctly in the Flight Planning exam theres only about 3 points you have to mark on the NAP chart and all the questions centre around them with combinations of distance, average track, initial track, true and magnetic. Dont try and take shortcuts with it as it's so easy to mess up.
Hope that helps.
