How to back out FPL changes on GNX-480?
It never ceases to amaze me how I keep finding something I don't know how
to do on the GNX-480 after all this time. Had a flight plan going when I got a pretty significant re-route in flight. I went into FPL, hit EDIT, and started deleting waypoints with the CLR button. After a while, I realized I had deleted more than I wanted to, and that's where I got stuck. I know the newly edited flight plan isn't activated until you hit EXEC. But is there any way to just throw away what you've got in the edit buffer and revert back to the last executed flight plan to start editing again from there? The best I could come up with was to re-enter the waypoints I had accidentally deleted, then enter the new ones, then hit EXEC. |

Lots of useful information there. When you go the the intial FPL screen (you may have to push BACK on the view screen), It will at th the top show: Active Modified (in green) ----------------------- (list of flight plans in the library) You can two things at this point. You can press CLR at this point and it will ditch the Modified plan (ENTER for yes, CLR for no will pop up). You can also go back to looking at the Active plan by turning the BIG knob to select Active and then press view. |

Hey Roy, I suggest you might want to join the YAHOO GNS480 owners group. Lots of useful information there. I didn't know it existed; thanks for the pointer! When you go the the intial FPL screen (you may have to push BACK on the view screen), It will at th the top show: Active Modified (in green) ----------------------- (list of flight plans in the library) Yeah, I got this far, but it never occurred to me to hit CLR at that point. Why don't they just have a "Cancel" or "Revert" button at the same page where they have "Save" and "Exec". That would be a lot more logical to me. |

That would be a lot more logical to me. CLR is the general delete key on the 480. Another cute feature on the CLR key is that you can highlight the "discontinuity" in your flight plan and just "CLR" it. The box then replaces the discontinuity with a direct routing between the two discontinuous legs. |

I was starting to wonder if you'd ever get around to it :-) |

I have a 480 as well, and am very happy with it. I got the IR a few years ago, and I've often wondered whether it would be easier or harder with the GPS. At the time I did the rating I just had two Nav/com's and ADF, so was limited to the traditional approach types. GPS approaches are definitely easier than non-precision NDB approaches, and checking cross radials with a VOR is definitely a lot more work. OTOH, with the GPS you can get fixated on the button pushing and get tangled up in getting the box set up the way you want it. Another handy function on that main flight plan page is the ability to Reverse your flight plan. For simple point to point VFR flying, that turns out to be quite convenient. Mike |

I have a 480 as well, and am very happy with it. I got the IR a few years ago, and I've often wondered whether it would be easier or harder with the GPS. I've had the 480 in the plane for a bit over a year now along with an MX20 and CHARTVIEW. My instructor was pretty adept at teaching the 480 "button mashing" and we practiced on the 480 emulator on my lap top while flying the desktop simulator he brought. Between his instruction and my previous experience it wasn't hard. The moving map makes the rating almost too easy :-). It certainly makes the partial panel approach a trivial issue, just zoom up the 480 screen and watch the pseudo-HSI and bearing to station. The only caveat I can say is be sure to follow the purple line on the MX20 AND NOT the lines on the approach plate. There's sometimes a lag in the plate realigning with the course and we had a bit of confusion because the KSHD GPS23 has a "not to scale" piece on the chart which led me to inadvertantly enter the hold early (oops... crosscheck, crosscheck). I did almost all my training before I realized the volume on the alerts was turned down. I didn't have the little lady going "bong missed approach" until the last day. The thing also saved my butt on the checkride. I dutifully loaded up all my radios with com and nav freqs on the ground prior to taking off. When I selected the ILS, it goes "Boing" and tells me it's put the ILS freq into the flip flop for me. Ooops...the one I've dialed in is a megahertz off. I would have caught that when I ID'd the thing, but I appreciate the explicit heads up. The only thing we couldn't figure out an easy thing for is how to back it up to the holding pattern if you let it sequence out of it while circling an additional time. You can turn the FPL back to the holding entry (but not the hold) where it thinks you want to go direct to the fix and hold again. We just ignore the GPS proposed nav instead and fly around one more time and let it catch up with us when we finally go inbound. The only other fun thing is my 480 goes to the HSI. During partial panel GPS approaches the stickies cover up the CDI on the HSI. The CDI on the 480 goes away during GPS approaches as well. Again, I just zoom up the display and drive the purple line. |

We just ignore the GPS proposed nav instead and fly around one more time and let it catch up with us when we finally go inbound. Hit -D-, scroll up or down to the holding fix, then select Hold from the menu (might have to hit More once or twice to get to the right page). Watch out for how it describes holds: the GPS *always* uses "course to" to describe the inbound leg. If the fix is a VOR, ATC will have probably said "on the XXX radial", which is essentially "course from". My experience is that most people never really learn most of the -D- functions. They get "Direct" and "Dest", but rarely explore the OBS, CRS To, CRS From, Hold, etc. I once actually found a use for the Parallel Track stuff. Coming back to HPN, ATC gave me "Direct Tappan Zee Bridge". The bridge isn't in the database, but I was heading south and I know the bridge is about 5 miles west of the airport, so I just put in "direct HPN" and selected a parallel track offset 5 miles to the right :-) |

If the fix is a VOR, ATC will have probably said "on the XXX radial", which is essentially "course from". That does the same thing really as just sequencing back to the holding fix on the expanded approach. It assumes you are want to go to immediately to the holding fix and perform the pattern entry.

OK, I'm confused. Isn't that what you wanted to do? |
