Given: True Track 245° Drift 5° right Variation 3° E Compass Hdg 242° Calculate the Magnetic Heading.

 

Ans= 237deg.

 

draw a table C D M V T

 

I started on the right with True track 245 then apply variation 3 E (going to the left we take it off)

 

This give us a mag hdg. 242

 

there is no dev given so mag hdg is 242

 

we are drifting 5 deg to the right so we must be hdg into the wind by this amount. ( Ie we are pointed to

the left by this amount )

 

So hdg 242 is reduced to 237 ( The magic answer )
