The station is installed on aircraft and provides information to the aircrew:
about on air, ground, surface, stationary and moving objects;
about the earth's surface, atmosphere, water areas, forests;
about weather event.

RL plays an important role in flight safety and facilitates flight in instrument flight.

The radar is installed in the nose section of the helicopter and closed fairing made of material and it radio waves passing through. Depending on the radar type, the nose cone can be designed as a "Dolphin nose" or “Beard".

reflected radio signal) the antenna can be rotated at a certain angle.

Indicating device.





The basic principle of radar operation is based on the effect of radio signal reflection from the object.
Depending on the density of the object observed by the radar indicator devices display them in different colors on the monitor.
The denser the object, the darker the color on the monitor. Radar can also determine the speed of moving objects, which also differ in color.

weather radar receiver is set up to depict heavy returns as red, medium return as yellow and light returns as green on a display in the flight deck. Clouds do not create a return. Magenta is reserved to depict intense or extreme precipitation or turbulence. Some aircraft have a dedicated weather radar screen. Most modern aircraft integrate weather radar display into the navigation display.
In order for the reflected radio signal from the object to be received, a powerful transmitter is required. Radio waves used in weather radar systems are in the SHF (Super High Frequency) range such as 5.44 GHz or 9.375 GHz. The radius of the radar is up to 550 kilometers.

Radar radio waves are very dangerous for their powerful radiation, so it is in the area of the radar beam is very dangerous to human health. Therefore, the type of these devices is turned on during take-off and off during landing.
