P.1.An aircraft heading 130° (M) has an ADF reading of 190° Relative. The heading to steer to intercept the 170° track outbound from the NDB at 30º is:
Heading = 130 M
Rel Bearing = 190
QDM = Heading + Rel Bearing = 130 + 190 = 320
QDR = reciprocal of QDM = 320 -180 = 140. i.e a/c is on the 140 radial/outbound track and heading 130.
If a/c turns 10 degree right it's heading and outbound track will be equal(140 M), if it again turns 30 degree right(170 M) it will fly parallel to 170 outbound track and another 30 degree right (as it has to intercept at 30) it will intercept the 170 track at 30 degree. So it has to turn a total of 10+30+30 =70 degrees to right
Hence heading to steer = 130 M + 70 = 200 M
