Mark,

I did not know that Airliners didn't have WAAS. What signals do they use? In backup then you would use your standard altimeters that should be certified to Whatever the pitotstatic error margins are.

I started reading this thread 3 days ago. Very informative, from Dave's original post to Mark's videos.....So I have reached the end of all 77 pages in this thread. Very interesting. One question that I don't understand is this.....
RVSM costs a pretty penny. Almost all aircraft now have GPS and RAIM to check for errors. With WAAS you get within 4 feet accuracy vertically, so why don't aircraft and ATC use the aircraft's GPS derived altitude? Even with RVSM equipped aircraft, the altimeters must have some error in them so what am I missing?

Remy

Couple thoughts. Airlines don't have WAAS and neither do most legacy jets. More importantly, what would happen if the GPS system went down? You would have a massive problem on your hands. All it takes is watching a commercial jet pass over or under you at 1,000 feet at a closure rate of 1000kts and you will get religion about having the most accurate reliable system possible. Hence RVSM.

Is WAAS available everywhere? Over the ocean? Do other countries use the same system or have it at all?

WAAS is US only.

EGNOS in Europe.

Some other systems in other areas of the world. Many geographic areas have no WAAS equivalent.

Airlines use Inertial Navigation Systems (INS) and not GPS.

Explain to me what RVSM certification does anyway differently vs what my G1000 does at FL280?

Hey Mark, I've been enjoying your epic thread - Beechtalk classic!

(Do we have a hall of fame archive? Here's my nomination)

Love the perspective, the info and lessons learned. Maybe I'll be in your shoes someday, if not I've got a good look at the view, thank you.

Hope you keep it rolling, I've got it bookmarked.

I assumed he felt bad because he didn't have any co pilots' to share pics of lately or maybe he is not flying. Oh my that would be like Mike B not spinning an amazing tail... Tail do you see the rhyme to my reason? All flying related...

Come on Mark we need some good approaches to learn from...

Oh I have been flying. Went to mammoth Mtn yesterday to ski. Got diverted from Scottsdale to Deer Valley due to a disabled AC on runway on return flight. . Flying the rocker to Spokane this weekend. Looking for a copilot. All my BTers talk a good SIC game but never deliver.

I will come up with some video soon.

As promised. Nothing remarkable. Just two landings and a takeoff at night. Well I did move the camera so Michael P will stop whining.

Last I checked you normally have to be cleared to land if there is a tower. I heard something like an approach clearance then "report YAFDY" which I heard "airport in sight". You guys must know each other.... or I missed something

Correct! On both counts. I did not report YAFDY as requested. I actually reported (er mumbled) "field in sight" and he did not respond. I did ask for a wind check (which was a really subtle way of reminding him I was about to land) he gave me the winds and I landed.

I went back and listened to the tape and discovered he did not clear me to land.

We know each other but have never met in person.

There is a standing joke that they ask me to report leaving the class Delta when in the seaplane and many times I forget because I am down low scoping out a lake. I suspect he thought "same old iceman....forgetting to report."

Why didn't I report YAFDY???? This is an important component to this story. (Hint...I didn't forget)
