I may be wrong but I cannot find a way to upload user (preferably protected) waypoints each time a new aircraft arrives, or unit is replaced ..... tiresomely boring
Could manufacturers not think of such a simple requirement?
Some have done so. The Chelton Flight Logic system (which is STC'd for Bell, EC, Enstrom, and MD light turbines in the U.S.) provides for transferring both user waypoints and flight plans from one acft to another.
