Radial - i have - i want - i set ( heading)
Now QDR ( out bound ) same versus , you Are on RAD 210 want 240 ( so right) set 270 ( right).
You Are on 210 ,want 180 ( left) set hd. 150 ( left) always same versus.
QDM is the opposite es 040 want 070 ( right) so hd.LEFT 010
040 (RAD) want 010 (left) so hd. RIGHT 070 .
Hope this is clear.
