Assuming steady inputs, the antenna would eventually stabilize at the center. Dipping this antenna into the ocean would create a ground plane and allow for communications with dormant submarines through the earth quote:Their resolution will provide the necessary survivable strategic command link to the submarine-launched leg of the strategic nuclear triad well into the future http://www.globalsecurity.org/wmd/systems/e-6.htm

This is all wild speculation, but I'd guess that weight*position plays a role with the weapons loadout (put the heavier weapons close to center line). Also the side mounted rails likely exclude non-propelled weapon releases (bombs), but I'll let someone with experience chime in. Are sidewinders effective against helicopters? I imagine those are common in our current wars.

Phanatic posted:The whims of Congress. ITAR is loving retarded. For a few years strong encryption was on the list as a munition, so you couldn't even send a floppy disc containing a copy of PGP overseas without risking prosecution. It's one of those things where the law's so labyrinthine and arbitrary that is is for all intents and purposes impossible to comply with it, everybody's probably in violation to some extent, and everyone occasionally gets charged with violating it. What a frustrating ordeal; I imagine their contracts include that clause now. It's surprising they'd overlook the requirement for delivery to include any material for certification, although my perspective is from the commercial world which I imagine is more boiler plate... Even at the daily paperwork level ITAR has impacts. Everything needs an ITAR stamp spaced at a specified interval. Anything labelled ITAR must be controlled. It's serious stuff... When you're looking at a spec for a zip tie it sounds ridiculous, but then you hear stories about espionage and the measures begin to sound rational. Apparently Chinese visitors were touring our factory with special shoes to collect metal chips for material analysis. With enough bits and pieces of info you can begin to assemble something of value. edit: 767-300F! The UPS freighters are roughly half the 767F fleet.

StandardVC10 posted:Interesting that they mention Asiana. As far as I know they still have only the one 767-300F. I've always wondered about single-plane subfleets in larger airlines (another example: Icelandair's TF-FIX, their only 757-300 amidst 757-200s.) It seems like it would be a hard thing to schedule around. But I'm really unfamiliar with how airlines schedule their fleets. The name or definition of an airframe model is pretty subjective to what you're interested in. Some people just care that it's a 767, others only care what engines are on it. The uniqueness can be specific down to the customer or even tail. Looking further into it, the uniqueness of the UPS 767 appears to be mostly internal; just a really large order. I only hear 3rd hand info about airline operations, but you can imagine commonality is a huge priority. The infrastructure required to operate an airframe is significant; maintenance personal/training, documentation, spares, etc. To justify another set of that would require a huge offset in cost (fuel, reliability, range/payload). I'm sure every airline has an army of accountants running the numbers on these trade offs.

I think USB outlets+WIFI is the ideal model for IFE. Consumer electronics cycle so fast, any integrated IFE will be stale by the time it's in the air. Provision for the unknown rather than lock yourself down. Bring your own ipad or rent one from the drink cart.

PatrickBateman posted:UAL isn't happy with their ife on the 787. The first few airplanes will have an older system since the config was frozen quite some time ago, later airplanes will have a better system installed. Plus it's all post merger stuff. That always throws existing aircraft orders into chaos. Generally I've seen the airlines order specific features for IFE equipment. Was UAL's order less descriptive? If a config was locked, shouldn't it be locked with the customer's option?

smackfu posted:Honestly I would put most IFE issues on crappy software rather than the hardware. Is the software sourced by the carriers or do Boeing / Airbus do it to order? I believe both can happen, depending on the order. "Buyer furnished equipment" or installed by Boeing. I know little about the software, but I believe IFE stuff is treated like an LRU... If an airline wanted to redo their IFE software, that would require some level of re-certification, correct?

Phanatic posted:Second, these things absolutely cause interference. The dirty secret is that so does everything else on an airplane. The microwave oven causes interference, the radios cause interference, every single piece of electronic hardware on the airplane interferes with all the rest (slight exaggeration but not a big one), all the time. So where it's important, that equipment is designed to tell the difference between interference and actual meaningful input. That's the reality that isn't addressed by policy or public perception. EMI can be calculated and countered through shielding and digital signals. I've heard an anecdote of Russian contractors being given a simple drawing update for a plane that's out of production but still flying. Inevitably one of the contractors would have a PHD in EMI and would run the analysis, find a potential EMI issue and report it. Unfortunately that configuration had been flying for 30 years with no issues, but since the issue is known, it must be acted on. Go go fleet update!

So the FAA and Boeing are going to review the 787. The media is playing up a conflict, but the word from Boeing's mouth is more along the lines of "sure"...quote:Boeing spokesman John Dern said it was inaccurate that Boeing opposed the review. He said Boeing's discussions with officials were about "the scope and structure of the review" and to "ensure that an accurate picture of the 787's performance" would be reflected in Friday's news conference. "Our engagement with the FAA was cooperative and constructive from the outset," he said.

SCOTLAND posted:Here is a pretty good writeup on it http://www.aspireaviation.com/2013/02/14/boeing-777x-787-10-unfazed-by-787-battery-woes/. quote:Unlike the folding wingtip being studied for the original 777-200 in 1995 that included the aircraft’s slats and ailerons, the 777X’s folding wingtip is only going to include the outermost 11ft (3.35m) of the wings with no moveable parts. In order to quell concerns about the complexity of the folding mechanism and the implications on maintenance costs, Boeing has adopted a folding wing which is a “major scaled-up” version of the carbon fibre reinforced polymer (CFRP) replacement wings for the Northrop Grumman A-6E Intruder fighter jet in the 1980s. That sounds like a movable part to me... Still cool, especially the weight savings aspect. And I wouldn't dismiss the gate space savings; it's all about the business case, and apparently Boeing feels there is one.

Outside diameter is 12'4"... And the engine shroud probably adds ~2' to the OD. But like you said, close enough. http://www.b737.org.uk/techspecsoriginals.htm I incorrectly thought the Originals/Classics had a smaller diameter than the NGs...

Anyone looking to start an airline? Boeing's website has an interactive tool to help visualize capacity of their planes, new and old. http://active.boeing.com/commercial/Startup/index.cfm Obviously this is an approximation of range, but it's interesting to compare performance through the generations. The startup section of their site has lots of interesting information about starting an airline. It's surreal to see how billion dollar business ventures being marketed to like it's Amazon.

So the jobs in SAT and CMES were both closed out, but nobody wrote a Removal order for the bolts so there was no corresponding job to restore the bolts. Officially, the door was never opened, even though opening the door was a physical requirement to replace the damaged seal. If only the Digital Thread was finished, it would have caught those bolts!
