THE RMI (Radio Magnetic Indicator)
gives the magnetic bearing from the aircraft to the station.
It can display both VOR and ADF
bearings; for VOR bearings use variation at the station for ADF bearings use
variation at the aircraft.
In this question the bearing to the
station is 178ºM, variation at Lajes is 15ºW (taken
from the chart), giving a true bearing of 163ºT and a bearing to plot from Lajes of 343ºT.
To plot this bearing line up your
protractor with the nearest meridian through Lajes.
Having plotted the bearing, arc off
135nm (using the latitude scale: 1'lat. = 1nm, 135nm = 2¼º lat.).
This should give you something very
close to 40º55'N 027º55'W.
