The GX50 is something of an oddity in some ways. I actually make a
fair amount of money just showing people how to set the OBS in that box. It doesnt work like the others--wont read it from the external display, you have to set it on the keyboard, and they hid it real good, both on the box and in the manual. For any GPS to be IFR approach approved, it has to drive an external CDI indicator. In most installations, it shares the NAV1 indicator with the #1 VOR receiver, and there is a switching unit on the panel (somewhere), external to either the GPS or the indicator that controls which box gets to talk to the display. Some of the GX50 boxes came with their own, third display which is dedicated to the GPS, so in these installations there is no NAV/GPS switch. The Garmin 430/530 boxes incorporate the #1 VOR rx and the GPS into the same chassis, so on these boxes the NAV/GPS switch is a pushbutton on the front of the box, rather than on an external panel. They also renamed it: the button is labelled CDI, and the annunciator it controls toggles between VLOC and GPS. It helps to sit down with your avionics tech and make a block diagram for your installation so you know how all this is hooked up--in *your* airplane. Think you got problems, consider the installation in a high-performance single or twin, typically equipped with GPS, autopilot and DME: NAV/GPS switch determines which box (VOR#1 or GPS) drives #1 CDI. NAV1/NAV2 switch determines which CDI the autopilot follows. Another NAV1/NAV2 switch determines which VOR rx is used by the DME for remote automatic channeling. These three switches are similar enough in appearance and function that a lot of pilots get really screwed up. Add to this some faded out labelling and you have a real opportunity to make a complete mess of things. (Why is that guy in the F15 flying so close to me and waving?) Gene |

Stan,
The point was not about the model airplane that would conduct the intercept--but why. It is a little known 'stat' about GPS that since we got them in little airplane cockpits the frequency of airspace violations have *increased.* People seem to be getting 'head down and locked' trying to wade through the many options and pages and modes on the black box while not noticing what is happening outside, i.e. penetrating airspace they do not have permission for. In general you must be correct; ie all of the intercepts I have been made aware of in recent years involved F16s--including one during Pres. Regan's funeral that had the F16 driver doing wingovers around our aircraft as we tooled down the ILS--he was intercepting some poor gentleman off to our left in a little Ercoupe that had apparently 'not gotten the word' as the saying goes. I do know of one gentleman (who, due to his incident became my customer under the remedial instruction program) who penetrated the restricted area over Groom Lake, NV and was intercepted by an F15. I suppose it has something to do with which types are based where. In either case, it is not something you like to see--military jets pulling up alongside your flight. I understand it is especially unnerving if they happen to have other than US markings. Regards, Gene |

Stan,
I was only kidding about the frightening part... little exaggeration. My closest encounter with a military type was when I came around the west end of Catalina island at low level, and as I rounded the corner there was an F16 coming the other way doing the same thing in the other direction. It wasn't *that* close (nobody had to maneuver)... and he *did* wave. Regards, Gene |

You didn't see them until they passed just off to the side, waving and grinning. I still hate to see an F101. -- Regards, Stan Not the F-101 I'm thinking about. Wingspan is 39 feet 8 inches. http://www.wpafb.af.mil/museum/resea...hter/f101b.htm Maybe you were thinking the F-104 which has a wingspan just under 22 feet. http://www.wpafb.af.mil/museum/resea...hter/f104g.htm J.

@news-1.nethere.net: http://www.wpafb.af.mil/museum/resea...hter/f104g.htm Yes, you're right, I meant F104. The numbers sometimes blur after 25+ years. ;-) -- Regards, Stan |
