You're fixin' to get jacked up breaking red like that. :v:

Actually, funny story about breaking red...so during Northern Edge last summer we had a shitload of Navy guys up here, even more than usual since the carrier dropped out so the bulk of their Air Wing came up here and operated from Elmo. Anyway, these guys don't exactly play by AF rules, and were breaking red all over the place. We mentioned it to them once or twice, and they kind of looked at us and mumbled okay...and kept on doing it. We didn't give a poo poo, but the Wing Commander hisself said later that day that NO ONE would break red...and the Navy folks kept right on doing it.

We used to fly up to McChord from San Diego, to ultimately meet the carrier at Puget Sound for workup cycles and whatnot. I can't even begin to tell you how many of my former shipmates (gently caress I hate that word) probably still have bootprints on their backs and/or necks from running amok on the line and pissing of the SPs. Some people just can't be taught.

I always used to ask people if they'd ever watched "WKRP in Cincinnati", and if they were familiar with Les Nesman's office. It's the best analogy I could come up with to describe the AF's method of cordoning. :)

NASA still flies a couple as test/research birds, and I think VX-30 might still be operating a few at Point Mugu. I worked on those old girls for a long time, still have a bit of a soft spot for them.

Imagine my surprise this morning when I rolled in to work (BGR) and that behemoth of an airplane is down at the other end of the runway! They apparently landed at around 9 last night, I wasn't able to get a flight plan to see when they're leaving again. I also didn't have a camera with me. :( Good to see that big bastard again though, first time it's been through here in several years. We have AN-124s here all the time, so the novelty of those has kind of worn off.

One of the guys who had never seen it before kept muttering "That's just stupid big. Stupid big. drat."

Maybe it's different on the 340 then...

My job is almost exclusively Saab 340 maintenance. They're a bit loud on the ground but quiet down nicely once you get in the air. The real trick is to not sit in the first 3 rows if at all possible. A lot of the later B-models also have a noise-cancelling system installed in the cabin that (when calibrated properly, which few facilities seem to be able get right) attenuates the noise by about 6dB.

The last ATR I flew on had a couple of loose interior sidewall panels, hooked in at the top but not completely seated on the bottom. *rattlerattlerattlerattle* for 2.5 hours. Ugh.

That's the right engine of a Saab 340B. I climb into those with no keys and drive them around the field on an almost daily basis! Without clearance from ground! (we have our own ramp and taxiway that's not used by the airport proper, but is also about 100 yards from and directly connected to the south end of the runway.)

That plane was just up here a couple of weeks ago for an engine swap. Rest in pieces, 340B-316. :(


They broke another one a few years ago when the chief pilot forgot to check the position of his gear handle before he started up.



Oops. That was a loving great airframe too, very well maintained before SB took possession of it.

Not with any kind of safety interlock, astoundingly. If the handle is up and the pins are out, the gear *will* fold when hydraulics come on. One of many design decisions that still causes me, even after six years of working on them, to say "Why would anyone do that?!?" at least once a day.

I fully expected the culprit to be a Cobham ELT97. I've never seen one catch fire, but they do love to spontaneously activate themselves. Sometimes with the switch in the "off" position. The Cospas-Sarsat folks really, really do not find any humor in that.

I worked on a project a few years ago, the intent of which was to turn one of these into an optionally-piloted vehicle. I was handed a whole pile of off-the-shelf stuff (with a Cloud Cap Piccolo II as the brain for autonomous flight) and told, "See if you can make this work."

I got as far as actually getting all of the flight control surfaces to respond to radio control, but then the client ran out of money and took his airplane back. :(

This is really high on my list of "things I don't want to see on my ramp in the morning." Oddly, it's also really high on my list of "things I'm going to take pictures of anyway."


TERRAIN. TERRAIN. PULL UP!





Ice storm last weekend, 10 more inches of snow last night, plus a cargo compartment full of records boxes and an unknown (but probably minimal right now) amount of fuel on board. Lots of extra weight behind the landing gear, and probably a stiff gust of wind or two was enough to overbalance it. No damage though, nice soft rotation into the snow behind it and an equally soft touchdown once some of the snow and ice was removed. I loving love winter.

Are those the old Mesaba Airplanes? I thought they went back to Sweden. Are they stilling flying around Europe in Delta colors?

I work for C&L Aviation Services in Bangor. We handle a lot of Saab's leasing and lease return maintenance, as well as their aircraft storage. We used to have a whole shitload of Mesaba planes in the old red NWA livery, and do indeed still have some wearing Delta garb. The one on its rear end in the picture was last flown by a South American airline whose name I forget, and I'm honestly not even sure who owns it anymore. We're just keeping it alive until someone else decides to buy it.

When one leaves our hangar after a heavy check, it's usually to go for a new paint job for the new owner/lessee. We'll have our own paint facility up and running within the next year though, so we'll be a one-stop shop for the customers. Christ, I sound like an advertisement. Can I interest anyone in a low-cycle 340B?

The S-3 seemed to be okay despite never having a well-fitting role.

As someone who spent nine years of their life working on S-3s, I sometimes still have an overwhelming urge to find the engineer who thought putting 54 lovely proximity switches (13 of which were in the lovely wing fold system) throughout the airframe was a good idea, and then kick him in the balls repeatedly until he vomits them up.

The emergency locator won't work if it's underwater, however. I'm not familiar with the ones used on aircrafts, but I assume they'd float, assuming they broke free of the fuselage.

The ones used on ships are designed to float free of the ship when it sinks (There's a pressure-activated release) but even then they don't always float away for a number of reasons... And they're usually strapped to a railing outside the bridge, not inside the hull.

Aircraft ELT units are (hopefully) automatically activated by a G-sensing switch, and they will also float if they happen to find their way out of the fuselage. They also have a manual switch, so if you go down somewhat safely in the middle of nowhere, you can just grab the box and turn it on.

If you have a Cobham ELT96/ELT97 from the early production runs, you can also count on them spontaneously activating themselves for no real good reason. The SARSAT guys and I have spent a lot of quality time on the phone together.

I've installed a few Flightcell systems recently, and I cringe every time I have to do the op checks. Not because I'm afraid it won't work, but because the satellite delay and shittastic audio quality make it very difficult to, oh, communicate.

Iridium is something like 2 to 10 kilobits depending on the equipment, but I think trying to talk in clicks and whistles at 4800 baud might actually make both parties more understandable.

A TCAS unit with Radio Altitude as the sole input wouldn't be compatible with the current system would it? I was under the impression that the barometric info was the primary factor, and the RA was more for the inhibit functions.

RAs based solely on Radio Alt would be horribly inaccurate in certain areas of varying terrain when you take a look at the lateral distances that can initiate an RA advisory.

You're correct. Transponder/pressure altimeter correlation checks are part of the FAR 91.411 certification process, and that same altitude data is also what TCAS uses for reporting.

I was a Viking mechanic for 9 years and also spent a little bit of time on H-60s, and I can't think of a single time where anyone was vying for power over the condition of an aircraft.
