The RCA22 Series of vacuum horizon 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 (14 or 28 volts). This is our “Standard” display.
All RC Allen vacuum gyros run off of 4.5 in. Hg, erect time is 3 min. Instruments equipped with a warning flag will let you know when vacuum has dropped below 3.8 in. Hg. Flag retracts from view at 4.3 in. Hg. The 3 ⅜” X 3 ⅜” x 6” instrument fits in a standard 3 1/8 panel cutout. Weight of unit is 2.75 lbs. A ¼ -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 gage installation.
