AZIMUTH RESOLUTION

The ability of the radar to resolve
adjacent targets in azimuth is a
function of the beam width of the
antenna and the range to the
target. As can be seen in the
adjacent table, the diameter of this
radiated beam increases as it gets
further away from the aircraft.

Targets separated by a distance less
than the beam diameter (at the target
distance) will merge and appear on
the indicator as “one.”

PATH PLANNING

Remember to plan a deviation path early. Simply skirting the red or
magenta portion of a cell is not enough. Plan an avoidance path for all
weather echoes which appear beyond 100 nautical miles since this indi-
cates they are quite intense.

The most intense echoes are severe thunderstorms. Remember that
hail may fall several miles from the cloud, and hazardous turbulence may
extend as much as 20 nautical miles; therefore, echoes should be sepa-
rated by at least 40 nautical miles before you fly between them. As
echoes diminish in intensity, you can reduce the distance by which you
avoid them.
