Route Manager internals: Difference between revisions

Since most real navigation systems deal in ''legs'', not waypoints, the active leg is defined as that between <tt>waypoints[currentWpt - 1]</tt> and <tt>waypoints[currentWpt]</tt>. This is why current waypoint property is initialised to '1' on activating a route, and why activating a route adds the current location (usually the departure runway) as waypoint 0 - taken together, the user and GPS see the expected first leg from the runway to the first waypoint they entered.
