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.
