Description

The 4000HR air-driven directional gyro offers some of the best features of our other popular models.  It inherited all of the functionality and reliability of the industry standard 4000B upon which it’s based, and it picked up a heading reference bug from the 4000C autopilot model.

Many pilots find the heading reminder a valuable feature whenever the cockpit is busy, such as during an approach with heavy ATC traffic. Setting a new heading during a long, cross-country flight eliminates the tedious math associated with frequent navigational crosschecks. A quick glance at the instrument instantly reminds the pilot of his heading. The heading bug can be positioned anywhere around the heading card by turning the right knob.

 

4000HR Heading Reference Options

This configuration includes a “heading reminder” bug previously found only on Auto-Pilot gyros. It reduces pilot workload and is a very valuable upgrade.
