RC Allen 22-Series Lighted Vacuum Horizon Gyro, TSO
The RCA22 Series of vacuum attitude indicators are controlled by an air driven precision gyro to present the pilot with pitch and roll information. The attractive color scheme of blue sky and brown ground presents a realistic spherical display of flight. Unless otherwise indicated all instruments have a blue/brown display, fixed pointer and are lighted or unlighted.
All R.C. Allen vacuum gyros run off of 4.5 inch Hg, erect time is 3 min. Instruments equipped with a warning flag will let you know when vacuum has dropped below 3.8 inch Hg. Flag retracts from view at 4.3 inch Hg. The instrument fits in a standard 3 1/8 panel cutout. Weight of unit is 2.75 lbs. A 1/4-18 NPTF nylon tube slip fitting is recommended for vacuum hose installation. A 1/8-27 NPTF nylon tube slip fitting is recommended for vacuum gauge installation.
