True
Q3.
[TRUE/FALSE]
Fill in the blanks:
(10)
i.
QUJ is the bearing of DF station from the aircraft, and is measured in a clockwise direction
from True north.
ii.
Heading vector is represented by a straight line with ONE arrow (s).
iii.

iv.
Increase in TAS will Increase the distance to PNR.
v.
Increase in TAS will move the CP to the still air mid-point.
vi.
A Large scale map covers comparatively less ground distance and therefore, more
ground features can be inserted.
