Electric Attitude Gyros LUN 1241 3-inch Electric Attitude Gyros Description: The rugged 3-inch Electric Attitude Gyro (indicator) is a direct reading instrument indicating pitch and roll (bank) attitude. Its operational range is through 360° both in pitch and roll. There is a field of controlled precision at pitch attitudes exceeding ±70°. The primary display component is a spherical surface with a scale providing for pitch attitude indication within ±20°. On reaching this limit a window in the display surface opens and a digital pitch angle presentation is displayed up to a value of ±70°. The roll attitude is indicated on a roll attitude scale up to ±90°. The display corresponds with viewing the earth's surface from an aircraft. The attitude gyro is provided with a caging gear, with an aircraft symbol (with position adjustable between +10° and 7° of pitch attitude) and with visual malfunction indication. Attitude Gyro is offered to comply with customer's specification and is mounted for easy servicing.
