Figure 20.6(b) Typical weather radar control panel

allows each pilot to select the range of weather

radar in increments of 10, 20, 40, 80, 160 and 320


The electronic display is overlaid onto the map

mode allowing the pilot to relate the aircraft’s

heading with the weather images. These images

are colour coded to allow the pilot to assess the

severity of weather conditions. Colours (ranging

from black, green, yellow, red and magenta) are

used to indicate rainfall rates that can be

interpreted as a level of turbulence.
