Benefits

Radio altimeter, doppler system and air data system is configured in a single design solution in a single body, installed on the lower hemisphere of the helicopter and provides:

measurement of radio and barometric altitude
automatic measurement of the speed vector, velocity modulus, helicopter drift angle and coordinates, independently or in combination with the BUO-45 unit
air flow direction and speed
environment temperature
helicopter vertical speed measurement

RA, Doppler and ADS suite supplies data in a digital form to the BUO-45 unit on the frequency of Doppler shift along three axes, speed vector, helicopter velocity modulus and drift angle with the following accuracy characteristics:

speed measurement in longitudinal and transverse planes with an accuracy of at least +/- 1.5 km/h
speed measurement in the vertical plane with an accuracy of at least 0.4 m/s
determining the altitude in landing mode at the height of: up to 5 m +/- 100 mm; - from 5 m and above, not more than 7 % of the measured value
pressure altitude of at least 0.1 m
speed relative to the air flow of at least +/- 1.5 km/h
air flow direction of at least +/- 5° +/- 5°

The RA, Doppler and ADS suite meets the requirements for the design group 3.1.2 (helicopter zone B) under the State Standard GOST Mil Reg 20.39.304 and the KT-160D requirements.
