- Page 3 CASTLEBERRY Instruments & Avionics General Information This attitude indicator is a precision gyroscopic instrument that provides the pilot with a visual reference of the aircraft pitch and roll attitude with respect to earth. To achieve this desired attitude indication, the gyro establishes and maintains a stabilized datum reference perpendicular to the earth.

- Page 5 CASTLEBERRY Instruments & Avionics 1. The Parallax Adjustment Knob is an optional item. Some models may have a cover over this adjustment where it has been preset by maintenance personnel. This adjustment is used to set the Parallax Indicator (item 2) reference on the actual gyro horizon after settling as viewed by the pilot. Aircraft engines should be on during this process to apply nominal operating voltage to gyro and to generate the required vibration to overcome static friction to simulate a real operating environment.
- Page 6 CASTLEBERRY Instruments & Avionics This knob is used for quick erect. Operation of the “Pull For Quick Erect” or also labeled “CAGE’ or “CAGING” knob is done by a steady pulling outward on the knob with a couple pounds of force until the gyro presentation has stopped moving and in a level indication of both pitch and roll attitude and then gently releasing the knob to return to its spring loaded position.
