Can a GPS approach be used as an alternate?

The point of the special rules using GPS as an alternate has to do with the fact that non-WAAS GPS is supplementary navigation. So you can file with the destination or the alternate having only a GPS approach, but not both. WAAS-equipped aircraft can file for destinations and alternates having only GPS approaches.

Is the Garmin 430 IFR certified?

So if your non-WAAS GPS is certified for IFR to the approach level—and a Garmin 430 is—you can use it for IFR and for training. That’s presuming it’s installed correctly and up-to-date. However, you will miss out on some of the best features GPS has to offer.

Can you fly GPS approach without WAAS?

LNAV, or lateral navigation, is a less sensitive type of GPS approach that typically allows descents to about 400 feet above the runway with the right equipment—and you don’t need WAAS to legally fly an LNAV approach. Any IFR-approved GPS receiver will do.

What are the standard alternate minimums of the alternate has one RNAV approach?

Standard alternate minimums for non-precision approaches and approaches with vertical guidance [NDB, VOR, LOC, TACAN, LDA, SDF, VOR/DME, ASR, RNAV (GPS) or RNAV (RNP)] are 800-2. Standard alternate minimums for precision approaches (ILS, PAR, or GLS) are 600-2.

What are standard IFR alternate minimums?

So, what are alternate minimums when flying IFR? Standard alternate minimums require the forecasted conditions at the time of arrival be at least 2 miles visibility and at or above 600 foot ceilings for precision approaches, or 800 foot ceilings for non-precision approaches.

How much does it cost to upgrade a Garmin 430 to WAAS?

You could have the unit upgraded to WAAS. Budget over $2000 for the upgrade.

Does Garmin 430 have DME?

Alternatively, you could put the GPS direct to the navaid, and select the Nav 1 page on the 430 and read the distance there. Garmin 430s etc are loaded with percision approach data and it all works out. The Garmin provides the DME data with the freq loaded and VLOC for localizer guidance.

Is RNAV GPS a precision approach?

LNAV approaches are non-precision approaches that provide lateral guidance.

How do I listen to VOR on my Garmin 430?

Here we discuss how to tune in a VOR frequency on the GARMIN 430….

Can you use GPS without RAIM?

IFR GPS units must automatically perform a RAIM check before beginning an approach. However, performing a RAIM check prior to leaving the ground will better enable pilots to plan ahead and is recommended specifically for pilots without baro-aiding (see below).
