Which one of the following displays areas of precipitation?
Refer to figures.
Airborne weather radar is designed for avoiding severe weather, not for penetrating it. It detects drops of precipitation (such as rain/snow/hail).
Weather detection is based on the reflectivity of water droplets. The weather echo appears on the Navigation Display (ND) with a color scale that goes from red (high reflectivity) to green (low reflectivity). The weather radar echo returns vary in intensity as a function of the droplet size, composition and quantity.
