When an approach is loaded, it is appended to the flight plan after the
destination airport. As stated earlier, the waypoints in the original
flight plan will sequence normally until the destination airport is
reached, at which time the 430 will navigate direct to the IAF waypoint
and automatically "activate" the approach sequence.


To cut to the chase, those of us familiar with using FMSes know to clear
the destination airport from the flight plan once the approach is
loaded. In a full-press FMS, this is known as a route-discontinuity.
And, clearing that discontinuity in a full-press FMS or a Garmin panel
mount will get it all to work as a flight plan with continuity.


On a GNS430, activating the loaded approach is simpler. PROC, ENTER.


I took another look at it and disagree. Once the IAP is selected removing
the airport can be done prior to a critical phase of flight, then
everything sequences without pilot intervention.


FPL, push small knob to get cursor, scroll down to airport, CLR, ENTER to
confirm, FPL to get back to NAV page.

vs

PROC, ENTER.

And if you have to change approaches, which sometimes happens, you can't
select a new one without a destination airport.
