Garmin 430

Forget the 430, get a 480. The 480 is WAAS certified out of the box. Garmin has been promising WAAS for the 430 since they started selling them. Garmin will, in time, provide the WAAS upgrade for the 400/500 series. The upgrade will also provide additional computational horsepower for stuff like radius-to-fix (RF) legs. |

In order to be approved as an IFR installation the 430 has to drive an external CDI or HSI where the G/S will be displayed.
What is the reasoning behind this requirement? (especially in light of glass panels cockpits) Jose -- You can choose whom to befriend, but you cannot choose whom to love. for Email, make the obvious change in the address. |

Jose,
What is the reasoning behind this requirement? (especially in light of glass panels cockpits) Well, PFDs have that indication. I guess the primary reason is a requirement to have the indication in the direct field of view of the pilot. -- Thomas Borchert (EDDH) |

(especially in light of glass panels cockpits) Jose A glass panel cockpit is different than a non-glass cockpit with a GPS box that is typically mounted off to the side. The external CDI or HSI is in the pilots primary field of view. Plus, some approved GPS devices have marginal displays at best. The Garmin 500/530 has a very good display but there is no requiement that you select that map page. Also, if that map page became your primary display you would then be unable to select a different page during the approach, such as the flight plan page. A full-press glass cockpit, however, separates functions where appropriate and integrates them when appropriate. Thus, the primary GPS box in this case is like an FMS screen in a transport aircraft and the display array in front of the pilot is the "super HSI, moving map, ADI" that more than satisfies the separation requirement from the primary database box and the tactical display. |

It's a great box. IMHO, anyway. I don't care so much for the SL30 nav/com but the 430 is very well thought out. I have 2 questions though.... to use the glideslope / VOR / LOC functions of the 430, do I have to have a glide slope indicator and VOR indicator or are these bits of information displayed on hte 430 unit? Contrary to a previous response, the G430 does have a glide slope function as part of the VLOC function. At least the one that I fly with does. The 430 does not indicate either the localizer or the glide slope on its screen however. You need to buy the separate indicator (CDI). Garmin has a free simulator and free downloads of the manuals from their web site. Get the sim and the manuals and you can learn the box in maybe 5 hours. Enough to get started flying with it and certainly enough to evaluate it thoroughly. You should have someone who knows the 430 in the right seat for the first few flights IMHO. Is this one piece of equipment enough to enable my 172 to be instrument certified? No. Required flight instruments are specified in Part 91. In terms of required navigation devices and a reasonable platform for instrument training the 430 would be sufficient along with a transponder. Hmmm, maybe a marker beacon receiver, too, to placate a picky examiner? Yes, but the OP asked about required equipment in general. The 430 certainly does not cover it all. You still need a Generator/alternator, sensitive altimeter, inclinometer, etc. ... from 91.205 It is possible his VFR-certified airplane has all these things already, but he didn't say that it did. I presumed that he was speaking only in terms of avionics. No doubt he has to have a sensitive altimeter, attitude indicator, DG (or better) and so forth. He heeds wings and a engine, too. ;-) |
