GLS Coming Soon

[braunpilot]

Thought some people would like to see what the new GLS approach plates look like. Was surfing the NACO website and here is the procedure graphic listed.

It due to go into service in Feb 2010 at KMEM.

Attached is GLS 36R MEM

I'm going to claim ignorance... what is a GLS approach? I'm not seeing anything odd on the plate other than it says it requires special aircrew authorization.

GPS based ILS. It's beginning in Memphis. Don't know what "Special Crew Authorization" is required. Thought you only needed WAAS and you were golden but I guess that I was wrong.

I wonder why you need the ILS frequency on the chart...hmm.

Did a little searching on the FAA's website and came up with this. It is a LAAS based system. So that is where the special aircraft comes in. I have the website that takes about it a little and a pdf I found.

I was starting to wonder what happened to LAAS. People seemed to stop talking about it.

Cool, I suppose in time they will take the mins down a little, but as of now, you might as well shoot the WAAS LPV approach.

If I had a WAAS GPS (let alone a GPS period) I would.

The chart has DME from the localizer in the profile view. Perhaps it is for some redundancy.

If you build it, they will come.

Just wait. As soon as the MLS is good to go, you'll probably never hear about LAAS, GPS, WAAS, ADS-B or any of the rest of that stuff again!

MLS??? uh, Multi landing system?

What ever you got in the plane...it will get you down to the mins. It even works well with the standard six pack.

Is it some kind of giant laser beam one can see even through heavy layers? What's next? Follow the skyway to the left! Put on these special glasses and you'll see it! What, you broke the glasses? Great, get the approach plate out and let's see if I can remember this stuff.

MLS (Microwave Landing System) was supposed to be the Wave of the Future back in the early to mid 90's. The FAA poured untold Billion$$$ into developing it and it was nearly on the verge of being viable when GPS became practical, affordable, and commonplace.

...but only turned out to be a micro wave of the future!

Thank You!
I'll be here all night.

I'm guessing that enough FAA people got promotions over the project that there'll be some proposed mention of the MLS in NextGen
