FYI - IFR GPS users

roundout

VNAV monitor
As disseminated through the news this morning:

Many previously IFR-certified GPS receivers might now be unapproved for flying many instrument procedures due to recent FAA policy changes, according to AOPA. On Thursday, the association said the FAA's Advisory Circular 90-100A, issued in March, indicates that only three GPS models -- the Garmin 400, 500 and G1000 series -- are now legal. Other models made by Garmin, including the new GNS 480 WAAS receiver, as well as receivers manufactured by Chelton, Honeywell, Northstar, and Trimble are listed as "noncompliant," AOPA said. The action means up to 26,000 GPS users no longer comply with a 1996 FAA policy that allows GPS to be used in lieu of ADF or DME. "This doesn't make any sense. In most cases, this is not a safety of flight issue," said Randy Kenagy, AOPA senior director of strategic planning. "Pilots affected will lose access to approaches and published routes unnecessarily." AOPA has brought the matter to the FAA's attention, telling the FAA that all IFR-certified systems should still be approved for use in lieu of ADF and DME and for flying T routes and certain departure procedures where pilots manually enter the waypoints.

Wow!! Does this seem fishy to anyone else? Why only Garmins? Conspiracy?

BTW, this does only apply to GA right? I mean all the airliners out there with GPS recievers on the FMS can still fly IFR right? I'd hate to think that going into the CRJ with a Collins 4200 is a step down from the G430 I was using in the Seminole.
 
so is the 89B still legal for random RNAV routes, i.e. airport to airport? every airplane i fly has an 89B (but they also have ADF and DME)

oh, and BTW, i have lost RAIM with the 89B 3 times in the last few months when inside the FAF with 8 satellites in view......
 
Well glad I got my DME arcs out of the way for my instrument rating a few months ago.

Yes, heaven forbid you have to learn how to do them without a GPS. I mean it'll never be necessary, right? You won't have to correct a Captain because he lost SA during a non-radar DME arc in the carribean, right?:sarcasm::sarcasm::sarcasm:

Sorry, just bustin your chops...

Stone- calm down. There is no difference between a DME arc with GPS and without it. There is no guidance offered by the GPS whatsoever- just distance information!

And yes, I did ALL my training without GPS.

I've never flown a GA aircraft that had an actual DME installed. And that's from 4 different schools in 4 different states.

No I just mean that because I wouldn't be able to practice them in our aircraft because we don't have DME. The KLN 90B only has an overlay for GPS and RNAV approaches so it really doesn't help much unless you can not picture how to do the arc.

Okay, nevermind...it sounded like your GPS showed you the arc and all you did was follow the line. Sorry!!:o
 
Thats ok you don't know me and how anti technology I am!

We have glass warriors here that I fly from time to time since they are cheaper. Out of 18 flights with it 14 have had either nav failure or a complete AHRS failure. The school won't let us fly into any IMC with it because it is so bad. No wonder Piper now switched to Garmin.

really? never heard of problems with the Avidynes. they dont' list Garmin Glass on the equipement options, just the 430

It's only an option for a few right now but one of the letters suggested that in a few years they should all be on Garmin glass.
