SIGMA-TEK BOOTSTRAP DIRECTIONAL GYRO 4000H-3

Sigma-Tek Directional Gyro 4000H-3. Sigma Tek's Directional Gyro 1U262-034-4 with heading synchro output provides a cost effective link to "bootstrap" other instruments requiring heading information for: display orientation to aircraft heading, heading stabilization functions, and other navigational calculations and/or solutions. The heading output efficiently tracks the aircraft heading as depicted under the index pointer on the Directional Gyro. The synchro index and rotation reference is set to ARINC characteristics.
