Sigma Tek 4000B Directional Gyro, Air

 

The 4000B is a standard air-driven, non autopilot, directional gyro.
 
This standard configuration gyro can replace most air-driven gyros with the major difference being in the layout and colors of the display.
It is a 3” instrument, constructed upon a rigid, cast-aluminum frame that houses a precisely machined brass rotor, which is suspended on high-quality, long-lasting bearings.
 
Operation: As the aircraft turns left or right, gears on the sensing unit and dial shaft translate this rotation into rotation of the instrument’s vertical dial. Left turns produce clockwise dial rotation and right turns produce counter-clockwise rotation. The gyro is controlled by a heading selector knob located on the lower left of the instrument. Pressing and turning the knob first disengages the dial shaft and then resets the dial to a new heading, which results in a new course indication. Releasing the selector knob re-engages the dial shaft. The on-course position of the pointer is always at the top of the azimuth circle (0° on the dial with the aircraft headed north).
 
Basic Specifications:
  • Height: 3.25"
  • Width: 3.38"
