Or, if you are flying multiple approaches and receive a clearance direct to another airport
and are awaiting the first approach clearance, then:
Method B
1.
Select the Direct-To page and select the DB soft key at the bottom of the
display. This allows you to select any airport from the Jeppesen database. Or
you can use the NRST function and select the airport of choice if it happens to
be in the neighborhood.
2.
After highlighting the new Destination airport via a method above, press the
Dest key. The DESTination key does a couple of things:
a.
It throws out your existing flight plan and replaces it with a one leg
flight plan consisting of a Direct-to the new Destination airport.
b.
It replaces the old Destination airport with the new Destination airport,
allowing you to select the next approach or arrival at that airport.
3.
Once the Destination airport has been changed you may select any approach
you wish and load it into the flight plan. This action DOES NOT
automatically give you a Direct-To the IAF by design, unlike older generation
GPS products. This is done specifically so that the active waypoint cannot be
changed automatically unless you, as PIC, change it.
4.
At any time you may select the Direct-To page and choose the IAF or other
waypoint in the approach and fly direct to it, using the Direct key.
5.
If you are given the full procedure, make SURE you select a transition that
requires a procedure turn. The CNX80 will then build the PT and fly it for
you with roll steering if you are so equipped. Do this if the IAF and FAF are
the same waypoint, and then do a Direct-To the IAF. This bypasses the
transition waypoint, but we don’t care, we just want to get a PT out of the
deal.
Vectors To Final:
You are given vectors at the last minute by a controller who suddenly decided to change
your full approach clearance. Simply accomplish the following:
1.
Select the PROC page by pressing the Function Key and,
2.
Select VTF mode in the lower right hand soft key.
3.
Confirm VTF mode by pressing ENTER.
This extends the inbound course to the FAF and makes that leg active for guidance. If
you wish to fly the same approach more than once, and you’re vectored around the pea
patch, then simply activate VTF again downwind and you’re all set.
