The TARSYN-H provides roll, pitch and compass data in one self-contained gyro package. The gyro package consists of a directional gyro synchronizer, an attitude reference (VG-401H), and a base. The gyro synchronizer provides compass information. The VG-401H provides vertical reference information while the base provides resilient mounting for the gyro synchronizer and attitude reference, common and external electrical connections, erection control and monitor functions. The erection and monitor circuits are contained on circuit card assemblies within the base. Electrical connections, external to the base, are made through a 32-pin and a 55-pin connector. The TARSYN-H has a length (including connectors and handle) of 16.08 inches, width of 6.53 inches, height of 7.63-7.70 inches and a weight of 15 pounds. The mounting tray has a length of 16.96 inches, width of 6.76 inches, height of 0.63 inches and weighs 1.1 pounds.
The TARSYN-H features an automatic initial fast synchronization which provides fully operational gyro synchronizer within 3 minutes. The TARSYN-H also has automatic fast erection which provides a fully operational Vertical Gyro within 3 minutes. The TARSYN-H's automatic roll erection and compass slaving cut-off during turns in excess of ± 6 degree bank. The TARSYN-H contains independent manual fast erection backup switches for the gyro synchronizer and Vertical Gyro. All roll, pitch and heading outputs are in accordance with ARINC standard requirements. The starting power requirement for the TARSYN-H is 115 V, 400 Hz, 120 VA while the operational power requirement is 115 V, 400 Hz, 70 VA.Part Number Differences:
