  • Page 18: Normal Operating Procedures

    S–TEC 3.1 Normal Operating Procedures 3.1.1 Heading (HDG) Mode Set the Heading Bug to the desired heading on the compass card (HSI or DG). Engage the GPSS Converter's HDG mode. Engage the autopilot's HDG mode. The autopilot will turn the aircraft onto the selected heading and hold it. The turn rate will be limited to 90% of a standard rate turn, although for some higher performance (turboprop) aircraft this is 75%.
