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 )
