It's not a mix of the Airbus design (assuming you're referring to the A330/340 winglet), but rather it's a winglet that's blended both upwards and downwards. Aviation Partners showed almost the same thing about 6 months ago.

You can make a blended winglet more efficient by making it taller. This design gives a similar effect.

I think it was in reference to the A380 winglet.

A pilot becoming overwhelmed by workload during a critical phase of flight is an extremely hazardous condition that requires immediate corrective action to prevent an accident. That corrective action didn't happen here, which is a big deal, but it's also worth exploring the factors that increased the pilots workload and may have caused the pilot to become overwhelmed (if that is indeed what happened).

Yeah, this is pretty much the approach you take in any industrial accident investigation.

Outright blaming someone, aka, "they should have known/done better" and stopping there misses a significant opportunity for the development of safer and more reliable practices. Sometimes there are unknown factors that contribute to the accident after all. Additionally, approaching the investigation from the perspective of "who do I need to blame" tends to make folks very reluctant to give complete information. Negligence or malice may still play a role, but you figure that out once the situation is understood and changes (if any) are made.

Even in cases where someone is just a complete gently caress up, it's still useful to know how or why they hosed up.

Random question for the thread: Why does the P-8A use raked wingtips rather than the customary blended winglets from the 737 it's based on? Or should I be asking why raked wingtips aren't on the current/NG/MAX 737s?

NTSB STATEMENT ON ERRONEOUS CONFIRMATION OF CREW NAMES
July 12, 2013

WASHINGTON – The National Transportation Safety Board apologizes for inaccurate and offensive names that were mistakenly confirmed as those of the pilots of Asiana flight 214, which crashed at San Francisco International Airport on July 6.

Earlier today, in response to an inquiry from a media outlet, a summer intern acted outside the scope of his authority when he erroneously confirmed the names of the flight crew on the aircraft.

The NTSB does not release or confirm the names of crewmembers or people involved in transportation accidents to the media. We work hard to ensure that only appropriate factual information regarding an investigation is released and deeply regret today's incident.

Appropriate actions will be taken to ensure that such a serious error is not repeated.

A group of citizens is suing the Navy over its use of an OLF that is very close to NAS Whidbey Island. This field has been in use for a very long time. The OLF is about 10 miles from the NAS proper.

Reminds me of the assholes complaining about the idea of some airlines adding a handful of commercial flights to Paine Field each week. We already have wide body jets taking off and landing there on a daily basis, for christ's sake.

So did anyone have a chance to read the request Amazon.com sent to the FAA requesting exemption from the experimental airworthiness regulations?

This stood out to me:

pre:
We also intend to use one or more of the six FAA‐selected test sites and seek a special 
airworthiness certificate (experimental category) for our sUAS.  However, it would be impractical 
for Amazon to pursue either one of these avenues as our sole or even primary method of R&D 
testing at this time, and doing so would unnecessarily tax scarce FAA resources.  For example, it 
would be an unreasonable burden on both the FAA and Amazon if we were required to apply for 
a special airworthiness certificate for every sUAS design or testing configuration while we are in 
R&D and conducting rapid prototyping.   
I've only had experience on larger commercial aircraft, but there's nothing the FAA loves to investigate more than tons of part changes and manufacturers who are new. Is this letter as unreasonable as it sounds or am I missing something?

They want to build, test, and iterate on their 55lb robot helicopter on some property they (will) own out in the boonies instead of having to go through the FAA every time they try something new. Low speed, low altitude, and with several automatic and manual fail-safe systems. It seems reasonable to me.

The whole testing in the boonies is fine by me (except the "special invitees" thing, keep it to essential personnel only), but the fact that they're asking to rapidly iterate materials, parts and software with no history of drone manufacture or certification is what set my alarms off. At least certify that all those fail safes actually work first. I just don't see why the inspections are such a huge deal when you're talking about something as relatively simple as a drone.

I guess what's really crawling up my rear end about this is the attitude of the company. Amazon is a tech firm and like all other tech firms they're used to obsessing over the bleeding edge of technology regardless of how well it works - hen their products crash no one dies. I used to work in food safety and now obviously in aerospace, and the stakes are much, much higher. Sure, we aren't talking about jumbo jets here, but I think it's way too early to be granting a company with no prior experience exemptions in the licensing/certification requirements.

Is there something I'm missing here?

PS: And we have poo poo like this happening already. When you start talking about transporting packages (mostly from airports) things are going to become very complicated. Maybe we just need a new set of regs to deal with drones, I don't know.

Snowdens Secret posted:

I edited out a too snarky part about how the government hands out exemptions to certain politically connected companies, often at obviously greater public expense, all the time. The Amazon case seems more the exception than the rule.

Your second paragraph would be relevant to a final product but make little to no sense on an R&D platform built specifically to be iterated. What good does it do the FAA to know Amazon once tried a different chemistry battery and it didn't help performance while flying over their private ranch so they went back to their old one? That this particular chord of blade was the sixth one they tried, and not the seventh? What public good does it serve to justify the interference? Is this just cranking up the cost of R&D specifically so your Boeing, Cessna, Robinson have less to fear from plucky new entrants into the market (like, possibly, Amazon?)

You're getting ahead of yourself here, and this lies in the root of my concerns. I'm certainly not an expert here, but I spent the last year working FAA Conformities.

Amazon has no history (please correct me if I'm wrong) of being assigned any sort of airworthiness certification what-so-ever. No prototypes, no destructive testing, no wear and tear testing, no nothing. We don't know how these drones operate under various conditions, the materials they're made from, the stresses they'll be under and so on. We don't even know that these drones are under a safe condition of operation. Who built them, and to what standards? Who approved the designs?

These are questions that can be easily answered, and that's part of the certification process. Once that's taken care of - that is, once there is documented evidence of basic airworthiness - then you can do your R&D, iterative designs and the like. Slight changes don't take all that long to add to the certificate, in fact if it's not that big of a change, it's trivial. Previous approved changes can be used so long as their certification is still valid. Once you have your baseline you get your Experimental Airworthiness Cert and you can do more intense testing and you're good to go.

Why is it that Amazon can't have their prototypes certified? Once you have that history of proving the airworthiness of your parts, materials and processes, certification becomes much, much easier to do. The reason you want Amazon to prove themselves (plucky new entrant my rear end, they have 60% greater market cap than Boeing) is because they've never done this before. They or any other new entrant should be the last people allowed to cut corners.

The whole concept of a paperless office is so out-there that people don't even stop to joke about it. It's an environment where absolutely everything needs to be stamped, signed, copied, stored, faxed, couriered (company mail) and emailed. All of that on every document of work. Those all-in-one document centres help, but it's still waaaay easier to treat them as a fax machine, press one speed dial button and whoosh, your job is done (even if the documents never made it out of the machine).

We certainly use a digital system for signing/tracking assembly and repairs here in Everett, is this not the case elsewhere? I think I remember even conformity paperwork being digitally signed, but that was two years ago.
