@egid I didn't go spelunking through the NTSB database, but the only references to accidents I found WRT own-ship position display during my googling were people talking about how having own-ship position on Class 1/2 EFBs could PREVENT accidents (especially when you take into account stuff like Foreflight's hazard advisor)

wazzaaaaaap?
I ate entirely too much at my friend's birthday lunch today
 
@voretaq7 yeah, that's the problem i've run into
 
("lunch" from like 1300 - 1730)
 
you can find plenty of FAA claims that it is unsafe, but no real reasons for why they think that
 
2:48 AM
@egid I honestly don't think there are any accidents caused by pilots staring at an EFB with own-ship position (yet).
@egid per my answer - "an overabundance of caution" :-)
 
and there's conjecture, but I can do my own ;)
yeah
 
same reason the other F-agency I deal with all-too-often (FDA) requires me to fill out literally 25 forms if I correct a spelling error in our software
Me: "We changed an `s` to a `d`, because the word is `and`, not `ans`..."
FDA: "BUT WHAT IMPACT MIGHT THAT HAVE ON SAFETY AND EFFECTIVENESS?" <clutch pearls>
Me: . . . o O ( Don't say "BITE ME!".... Don't say "BITE ME!".... )

Q: Short approach vs Normal

StanleyAll things equal, from a standard traffic pattern at a towered airport, is it safer to do a short approach when approved by tower, or a normal one? Assume a Cherokee, Cessna 172, or similar small trainer. My gut is a short approach should be safer, because I stay closer to the airport in case so...

i'm wondering if i actually answered this guy's question
now that i think about it
 
@egid I suspect if you TSO'd the GPS source and iWidget and permanently mounted it in the panel the FAA wouldn't care if it had a little airplane on it :P
 
@voretaq7 you and your $1.5m have fun doing that ;)

@voretaq7 just came back from the movies
 
@egid Hey then I can sell a $7000 aviation iPad :-)
Pilots are stupid, they'll buy ANYTHING if you slap a TSO sticker on the back :-D
 
<orders 1000 iPads with "TSO-C161a" engraved on the back>
@egid <Steve Jobs>TOO. MANY. BUTTONS.</Steve Jobs>
all the folks I know who've flown with the new GTN stuff say they're not happy with it in anything but smooth air - have you used any of it yet? :)
@egid I think you answered it pretty well. I kinda get his point about how big traffic patterns (like the Republic "Extend your downwind to Florida" patterns for runway 1 on busy days) can have safety implications
 
@voretaq7 I haven't, but that was the first thing I thought of when they announced it (actually, when they announced the G3000 (?) for light jets
I have a hard enough time working a 155XL or a 430 in turbulence
 
but I'm also the guy who flies tight patterns close to the field, because I'm in a Cherokee and if my engine dies my glide ratio is around that of a very aerodynamic rock.
@egid Like I said, I keep eyeing the IFD 440 - but I wanna touch it before I buy it.
 
2:58 AM
@voretaq7 I tend to fly very tight patterns too, for similar reasons, but I also taught students that way because it is the right thing to do
proximity to the runway means a lot of things for safety
not least is that other pilots have a better chance of spotting you since you're a predictable distance from the runway
and a side benefit is that you can get double the number of landings done in an hour, making you more proficient ;)
 
@egid a side benefit is I usually hear "31W Republic tower, are you able short approach?" and get to cut the line :-)
 
yeah, i get that once in a while too
my 1000-1500fpm climb rate helps with the "early crosswind when able" as well
 
if you're a mile out from the runway in your downwind you're not getting that offer - we don't have time for you to fly back to the airport :P
@egid my 1500FPM climb in winter fucks me over more than it helps me - all my avionics shit I do when it's cold, and the shop is at ISP (home of the "at or below 1400" restriction for VFR traffic)
it's nice at Republic though - climb....climb...climb.... OK let's just stop here until we've flown out from under Kennedy's airspace...

Courchevel Airport is a French airport serving Courchevel, located in a ski area in the French Alps mountains. The airport has a very short runway of only 525 m (1,722 ft) with a gradient of 18.5%. There is no go-around procedure for this airport. De Havilland Canada DHC-6 Twin Otters and DHC-7 Dash 7 turboprops served the airport in the past; however, the airfield primarily sees smaller fixed wing aircraft such as Cessnas as well as helicopters at present. The runway has no instrument approach procedures, thus making landing in fog and low clouds almost impossible. The airport is consid...

7:42 PM
@lnafziger I think that the 'air-tight' question requires an explanation of the outflow valve :)
which I just provided ;)
i think that's the answer he's looking for - cabins cannot be airtight because air is constantly being added to them, and that would make it pop
also, we need an additional 'close' option
we have too broad... but it looks like we now need 'too specific'
 
@egid yes, that question seems to be looking for very specific item / shop. I don't think we need to turn the site into a shopping guide.

Q: Possible need for a 'Too Specific' option when voting to close?

egidIn a couple of cases, we've had questions like this one that are asking very specific questions. Currently, the options people seem to use are either "off topic" or "too broad". Adding a "too specific" option, like "this is a very localized question" or "this only refers to one single model of a...

 
@egid I purposely avoided talking about how a pressurization system works, instead focusing on the end result and why they aren't made air-tight (since that is what he asked).
@egid A "Too Localized" like on SO would be good.
@egid We do need to get something written for the scope of the questions so that we can refer people to it though.
 
7:58 PM
yeah, that's true, i somehow missed the 'popping' explanation
it doesn't need a detailed description of pressurization, but i do think it helps explain why they aren't airtight
maybe we replace 'too broad' with 'outside the scope of this site'?
 
I really like the "Too Localized" on SO... It lets them know that if it won't be helpful to other people that we don't want it here.
Also, on the pressurization question, he didn't even know whether or not they were pressurized (which was the first part of his question) and if not, then why not make them air tight. I figured a nice simple explanation was in order, lol.
Actually, they got rid of Too Localized... grr...
meta.stackoverflow.com/questions/184154/… says that it has been replaced with more specific close reasons... I'm thinking that it may be more appropriate here though.

8:13 PM
@egid I can add "Off-topic because..." reasons. We just need to formulate one that works. I don't particularly like "too localized" or "too specific" since I think specific questions are good. But the question you linked to is clearly not the type of question we want.
 
8:30 PM
@egid @lnafziger see what you think about my answer meta.aviation.stackexchange.com/a/180/6
 
8:41 PM
@BretCopeland I saw that question when it first came up and would like some way to help people with those types of questions because it can be really hard to find a place to repair parts for some airplane types... Unfortunately, it really is too specific in a lot of cases (like this one) and think that we should not allow them....
 
@lnafziger I just don't think too specific is the reason that question should be closed.
It's more a matter of we don't want questions that are asking for recommendations. SO got rid of "too localized" for very good reasons.
 
Well, they got rid of it because people weren't using it right, and it wasn't as appropriate for the types of questions there. I think that it may actually fit for many of these types of questions here.
That being said, I'm sure that we can think of a different way of saying it.
@BretCopeland @egid Wouldn't this case be covered by "primarily opinion-based" though? I don't think that it really needs a new close reason when someone is asking for a recommendation like this.
 
@lnafziger I should have worded it as "opinion based or too geographically specific" because his question might not be so opinion based if he's specifically asking where can I get this repaired around here, and there are only one or two places which will do it. But I'm open to narrowing in on a better definition which better defines what too specific would mean.
 
@BretCopeland I think you are right with stating that we don't want questions that are asking for recommendations. This is certainly true for shops, but also for specific flight schools. In general those questions can be marked as "opinion-based", but this one is not clearly opinion based.
@BretCopeland "too geographically specific" does not really hold either, he just added a comment that he can ship his transducers to any place in the world.
 
The difficulty I find with too specific is that it seems incredibly subjective and might people who get their questions closed for that reason might find it even more frustrating than closing normally is.
@DeltaLima then it's opinion based.
(or at the very least, it's soliciting a list answer)
Again, if we can better define too specific I'm happy to use that.
@lnafziger btw, Stack Overflow has a specific "off-topic because" dealing with opinion based recommendations.
 
8:54 PM
Also the question seems to be looking for an answer that is like a commercial advertisement or at least a commercial recommendation
 
We already have the opinion based one, but it isn't in the list of off-topic's.. It's a top level reason.
 
> Questions asking us to recommend or find a tool, library or favorite off-site resource are off-topic for Stack Overflow as they tend to attract opinionated answers and spam. Instead, describe the problem and what has been done so far to solve it.
 
I took the question as having a real need... We get questions like that a lot on the NBAA mailing list, and they are professionals trying to get an airplane up and running.
 
@lnafziger a mailing list seems appropriate for that. So does chat.
 
Well, the mailing list is specifically for aviation questions, but yeah... I don't like it here because it won't help very many people.
Okay, I'll be back later to chat. Headed out for a bit now though!

Meh... @egid shouldn't use the same window for the chat and browsing the site.. ;)
 
@roe haha hi
anyway yes that's a good question
(re: what do submarines using electrolysis to create breathable oxygen do with the hydrogen)
 
roe
Yeah, I was just thinking, it seems like it's hard to remain stealthy if you're constantly bubbling weird gases out your back side... :)
 
yeah. if you're a nuke, you could presumably inject it into the reactor or something :)
(i have no real idea how that works)
BAE Systems says:
> These consist of Carbon Dioxide Scrubbers to remove the dangerous CO2 gas from the air and pump it overboard and machines called Electrolysers that produce oxygen with hydrogen from seawater. The oxygen is kept and the unwanted hydrogen is pumped overboard.
 
roe
cool
yeah, there's not a whole lot else you could do
 
 
roe
9:08 PM
burning it would just consume the oxygen again and produce water, so that'd be kinda dumb :)
 
haha
 
9:20 PM
@BretCopeland one of the things that makes me nervous about providing specific vendors as answers is... what if they suck?
I don't want to suggest a shop, even if I can google for them (like I did with the fuel sender question: airpartsoflockhaven.com/policies.html appears to overhaul fuel senders), because I have no first or second-hand knowledge of the services they provide
 
@egid right, which is why they shouldn't be out there for google to find.
 
the question/answer here, you mean
 
so, aside from sending him to LMGTFY, it oughta be closed
 
Yeah, but closed as what? That's been the point of the discussion.
^ it's very obvious people are currently undecided about what the close reason should be.
 
roe
9:31 PM
@BretCopeland They all feel like valid reasons to me, doesn't make it undecided. If you asked each person who voted to close, if they'd also vote for one of the other options, they'd probably say yes.. :)
 
@roe I disagree. The question is clearly about aviation and not off-topic for that reason. It seems relatively clear what he's asking, so it's not really that. It is sort of opinion based, but he wasn't really asking for opinions, he was asking for more of a simple list of places he could actually get what he wants. The fact that people are all over the place indicates there isn't an obvious reason the question is off-topic.
 
roe
@BretCopeland Yeah, you're right
So you're looking for a close-option like "Would require a specific endorsement"? Now that I've considered the question a couple of times, I'm not sure it's all bad. Just hard to answer, as I'd guess not a lot of people have experience with reconditioned fuel senders.

@Falk In reference to your Friday post, 747.terryliittschwager.com/designparameters.html explains a little of why the program looks as it does. Do you have an airplane. If so, send me the weight and balance info and I'll put it on it for you to play with if you like.

@Terry Nice; it looks very interesting indeed! No doubt hundreds of hours of work
 
@Danny I've never kept track, but I originally thought I'd be able to do it in a year. That was a little over 3 years ago. Not full time on it, of course, but just as the spirit moves me so to speak. It's become a bit of an obsession with me.

Q: Is it possible to "pimp up your aircraft" with an audio system?

Pato SáinzSorry for this sort of noobish question but, can aircraft be riced/pimped/tuned to have an enormous audio system, like the ones in cars? Has the FAA got any regulations on this (or maybe on in-cabin maximum noise volume?), would power be a limitation for the audio system?
