Hello All, What does the following NOTAM mean: GPS 02/001 GPS PRN 26 OTS WEF 0502082100-0502090900 I know it says "GPS Pseudo Random Noise 26 Out of Service" but what are its implications? Does it mean that RAIM is not available during the outage? Thanks,

I thought I understood this, but maybe not. GPS systems were certified for approaches after I got my instrument ticket, so my knowledge is more anecdotal than from actual training. Can an approach-certified GPS be used to substitute for NDB and DME during an approach (or even en route)? What if...

The single threaded fallacy GPS Sole Source Civil Aviation Navigation? Ask Wong Lee in Beijing what he thinks about that? http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2006/09/26/wchina226.xml

Someone in another forum said that it's okay to substitute certified GPS for DME or ADF on an approach plate that depicts FAFs or intersecting points using DME or ADF. I asked that person to back it up with a reference from an official document like the FARs, AIM or something that the FAA puts...

Flyers, I am parting with my the new Sporty's Air Facts DVD - GPS Techniques on eBay. Here is the link: http://tinyurl.com/3c6rpv It up for $5.00. I just bought it and enjoyed watching it and it indeed had some useful info. It discusses the 530, 430 and talks about the 396. It has two Air...

Just found out that the 2MB card we've all been using to update our GX 55, 60's etc will *not* work for the next data update. Jepp (to its credit) will *give* you a new 4mb card in return for your old one, but *act fast* since they are overwhelmed with requests and the deadline is fast approaching.

Can IFR-certified GPS be used to substitute for NDBs in Canada when navigating an airway? I'm a US-certificated pilot flying a US-registered plane. I'd like to take advantage of lower MEAs in western Canada provided by airways. Many of the airways appear to be between NDBs. If my ADF is known...

I actually posted this in another aviation newsgroup in which I actively post all the time but didn't get a reply... I assume because of the crash in Manhattan got everybody's attention. That being said, I'm still hoping for some insight from the more recently trained. ==== cut begins...

Flew my 172M today and experienced some truly bizarre GPS behavior. On preflight my portable GPS (Garmin 296), with external antenna and aircraft power securely attached, initialized just fine, acquired several satellites and went right into NAV mode. After runup and right before takeoff, it...

Does there exist a handheld GPS that talks? A very nice lady here at work wants to give her hubby a gift for his retirement, and she knows he likes GPSs, and she knows he likes the voice feature. So far I have not found one for her that talks. The only GPSs I know of that talk are permanently...

KIWS (West Houston) has a GPS (RNAV) Y RWY 33 as well as a GPS(RNAV) Z RWY 33. My KLN-94 only shows one of them. Is there a way to tell which one it is, without just a "mechanical" inspection of all the waypoints, bearings, etc? Is this a limitation of the KLN-94, or a limitation of the...

The Garmin 480 now supports LPV approaches which are ILS like approaches using WAAS-GPS for both LNAV and VNAV. My question. I'm assuming the LPV approach would target 1000ft down the runway as the TDZ (just like an ILS). Does this mean that LPV approaches will not be added to the airports with...

About to take a trip down to Gulfport MS (GPT) tomorrow morning. Ceilings are forecasted to be 300 broken, so I really doubt that I will be mucking around with full procedure approaches in the clag, but while I was studying the approaches into GPT, I am kinda figuring on expecting vectors for the...

Ok, it's coming up to that season, and was vividly demonstrated when I got hit by hail driving through Watertown last night. I drive a lot between Rochester NY and Ottawa Ontario, and Rochester NY and Whitby Ontario, and frequently those drives are in good VFR conditions except for that band...

For those who managed to escape all notice that the paper FAA certificates were being turned over to plastic cards, as publicized for the last two years: your paper flying license is now kindling, as from midnight last night! Regards Brian Whatcott with a brand new license to fly....

According to press statements, LAX has had a "guidance system" problem for the last several days. Is that general public speak for ILS?

We had a debate a couple of weeks ago about instrument failure recognition and partial panel. Here's another data point: http://www.dft.gov.uk/stellent/groups/dft_avsafety/documents/page/dft_avsafety_023258.hcsp It's the long-awaited report into the loss of a KAL cargo 747 shortly...
