How many regional pilots can REALLY meet this requirement?

I guess I never really thought about a lack of a solid state AHRS until this thread. What make/models? Just curious now. :)

Citation V (sim)
Citation Ultra (sim)
Dash 8-200/300

It's amazing how much quieter the solid state AHRS planes are up front without all the gyros spinning. I've flown the KA200/350 with the Pro Line 21 and a G1000 172 and all you hear is the whirrrrrr of the avionics cooling fans.

No wait, a Starbucks, because they aren't all 21...

So a large group of JC regulars walks into a coffee bar.
Does anyone even notice?

How could one not notice, what with all of the epaulets and ,"Why, hello there, cutie... I'm a pilot!" talk going on...

yes...because one is soaking wet, and probably on the floor, one has several very hot girls draped on him and the rest are talking and having a great time...and they probably don't even notice if someone else is looking because they are having such a great time.
But I guess you'd have to have been there.
 
I do have to say that looking back at this year's NJC, we've certainly cracked the code on women.

Even Cptnchia mentioned that a lot of attendees were "over girled" or something like that.

"Over chicked." And also demonstrated a higher IQ as well. Must be serving cold mint julips in Hell.

Women JC members/pilots, or woman attendees in general?

When say you've flown glass with mechanical gyro's are you saying there was a box with a gyro in it some where and used some sort of analog-digital interface to translate the mechanics of the gyro to some thing digital to be displayed on a glass panel? All the stuff I've flown has been either straight steam gauges or glass with an AHRS(though some of the glass had round dials for backup). That seems like soooo much extra work just for a fancy glass attitude indicator.

Learn some thing new every day. When I think of IRS I think INS, so I guess that's where I get that from. Makes since if you're going to have a laser ring gyro, you mine as well drive an attitude indicator.

Yes.


INS back in the day was spinning mechanical gyros.
 
I'm trying to think back to a class on long range navigation that I took. We had an IMU from, I THINK, a 767. It was a mechanical gyro with accelerometers.

I've done 25kts. Based on that, I don't think I'd try 30 except in an emergency.

Yeah, I did a crosswind in the 20s once and it was a tippy, squirrely bastard. If it weren't for the 150 foot wide runway and landing on one side and drifting to the other side, I'm not sure it would have ended well. So long as the mechanical turbulence isn't bad, I'm convinced a 210 with a full load could do a 100 knot crosswind! :D

What's an IMU?

No mechanical gyros in the 767 that I know of, except for the standby attitude! It's all triple-redundant laser-ring gyros. Solid state stuff. Here's a good schematic for how they work:

Inertial measurement unit. At least that's what it was called in the survey equipment I used. IMU, INU, INS, IRS, all the same right? :) This one was an electronic and a demilitarized unit from a Tomahawk cruise missile though.

ANYWAYS, I doubt they would still be using something so medieval today. I dunno though. How familiar are you with the navigation units on the 76 you're flying now? Supposedly the mechanical one was accurate enough on a trans-atlantic flight to get you within a couple miles. Good enough right? Obviously, you would have started to pick up the ground based stations a hundred or so miles out.
 
Oh, and LOOOLOLOLOL at that Onion schematic! I hate systems questions. I like systems, but the way some questions are asked are just stupid. I was asked to explain the PT-6 once. Uh, which part? What kind of vague ass question is that??? I told the check airman that the PT-6 converts fuel into noise and the noise spins the prop. :D

The IRUs on the 757/767 are generally fine. Non-GPS aircraft commonly map shift a half mile or so on coast-in after a crossing without a position fix, but that's reasonable. I once had a 767 actually go into a 4-5 mile map shift over Bulgaria (the system got a bad position fix), which was actually pretty aggressive while flying in LNAV. We just went into heading hold and tossed that VOR out of the system.
 
Man, you're bringing back a lot of stuff I thought I had forgotten. Except it's in bits and pieces.

How much do I not want to have dinner with the guy that thought up all this stuff! :)
