Weather radar can occasionally detect other aircraft, but it is not
designed for this purpose and should never be considered a
collision–avoidance device. Nor is weather radar specifically designed
as a navigational aid, but it can be used for ground mapping by tilting
the antenna downward. Selecting the GMAP mode enhances returns
from ground targets.
