Class: APNavDirector

Defined in: src/sdk/autopilot/directors/APNavDirector.ts:340

An autopilot director that provides lateral guidance by tracking a signal from a VOR or localizer radio navigation aid.

Requires that the navigation radio topics defined in NavComEvents be published to the event bus in order to function properly.
