The mask moves to indicate climb, dive, and bank. Bank and pitch attitudes are displayed so that the pilot’s sensing of the gyro indication is the same as the interpretation of the relation between the wings of the aircraft and the natural horizon during visual flight.The instrument is provided with a caging system which is functional through 360° of roll and 90° of pitch. When caging is engaged, pitch and roll indices are aligned within two degrees.This instrument is FAA certified, and can be used to replace the aircraft’s turn coordinator when equipped with an inclinometer.The caging feature is very useful for quick erection and display alignment; a high priority for occasional aerobatic maneuvers and operations with short stops.NOTE:Lighted instruments do not include lamp trays, please see accessories to purchase separately.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eManufacturer Part #:\u003c\/strong\u003e 1U149-024-4\u003c\/p\u003e","brand":"Sigma-Tek","offers":[{"title":"Default Title","offer_id":54255483289942,"sku":"10-02333","price":4909.8,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1037\/0164\/3606\/files\/10-02326_afaf0361-1c84-4b75-a5fb-fd927c7622c7.jpg?v=1781871706"},{"product_id":"10-02823","title":"Castleberry 300-14El 10-32V","description":"\u003cp\u003e300-14 SERIES ELECTRIC BACK UP ATTITUDE HORIZONCastleberry Instruments \u0026amp; Avionics introduces a new FAA certified back-up attitude indicator.
