Attitude Indicator AGB-3K ser. 2
The Attitude Indicator AGB-3K provides the pilot with visual information about the position of the object relative to the plane of the true horizon along the roll within the angles of ± 360 ° and the pitch within the angles of ± 80 °, and also issues electrical signals proportional to the angles of roll and pitch to external consumers.
The Attitude Indicator AGB-3 is produced in the following versions: AGB-3 ser. 2, AGB-3K ser. 2. AGB-3B ser. 2.
The Attitude Indicator AGB-3K series 2 and AGB-3B series 2 differ from AGB-3 series. 2 by the presence of light fixtures for the front parts of 9 indication elements): built-in red light for AGB-3K ser. 2 and built-in white light for AGB-3B ser. 2, as well as coloring of the indicator elements of the airhorizon.
Attitude Indicator AGB-3 series 2. AGB-3K series 2, AGB-3B series 2 are interchangeable with previously produced Attitude Indicator AGB-3, AGB-3K, AGB-3B, respectively, and differ in the type of gyromotor used.
The Attitude Indicator AGB-3K series 2 is used on Mi-8 and Mi-10 helicopters, on Yak-40, An-24, An-26, An-30, IL-76 and other aircraft.
