@ymb1 open the csv in notepad++ and then operate a search & replace? :P

ymb1

11:21

@Federico I tested a screenshot from excel, looks cleaner (subjectively)

a blatant copy & paste from Wikipedia for the tag info is acceptable, right?

falstro

11:59

@ymb1 I've also heard it called QFE (although that is a misnomer, since QFE is technically the altimeter setting to get it to show height above field elevation)

Federico

@ymb1 if you give me the data & link to the relevant post I can give it a try (screenshots are not really search-friendly)

ymb1

12:13

@Federico - DL kindly already had done it, it was his table to begin with (relevant revision)

it won't affect the indexing

subjectively, I like the bottom one, the screenshot one

ratchet freak

@ymb1 definitely more readable

never mind sorry, thought I caught a pattern @TomMcW nonetheless, how's it going?

long time no see

@ymb1 I'm good. You?

Where is the setting to get notifications sooner? I know I've seen that somewhere

@TomMcW all good

Q: How to get chat notifications quicker?

How to get the chat notifications quicker and without the 15-minute delay after tagging?

support

@TomMcW i initially sent you about this comment, thought I caught a pattern, I didn't

TomMcW

I could never quite figure that out. They will always add up to 360, so somehow that makes them also add up to the same number

ymb1

15:21

02/20 03/21 04/22 05/23 06/24 07/25

you're right, it is interesting

maybe there'll be a numberphile video on it :D

TomMcW

I can't find that prefs tab for anything. Maybe I have to be on a computer

ymb1

whether you're on mobile or tablet, open SE in browser, no app, scroll down and switch to full (desktop) mode to get the full functionality

Dan Hulme

@TomMcW but they don't always add up to 360

TomMcW

Well, 36

Dan Hulme

nope

TomMcW

15:25

I guess they don't.

@ymb1 I found it. Already had it checked. Why does it take so long. Seems like it takes 10-15 minutes

ymb1

@TomMcW updated the meta post for chat notifications, easier to follow though now

it's usually fast here, maybe 1 or 2 minutes, today SE were having maintenance, maybe that's it

Dan Hulme

I think the only pattern is that you started by thinking of examples that are all multiples of 30 degrees. Multiples of three always add to three.

ymb1

@DanHulme I was adding up the digits as the linked comment

for example 02/20 is 0+2=2+0

works for all but 01/19

TomMcW

@DanHulme If you take any two opposite runways and add the digits they are always the same

Dan Hulme

doesn't work for 10/28 either

ymb1

15:33

@TomMcW there it goes :( lol

TomMcW

@ymb1 Somehow the 10 throws it off

Dan Hulme

I mean, it works sometimes because they always have the same difference between them: adding 1 to one runway direction also adds 1 to the other. That's the same for any sequence like that. Any sequence of pairs with that property will work the same way.

TomMcW

@DanHulme I think you've solved it

ymb1

doesn't work for 11/29

TomMcW

If you add the digits and the result is two digits then you have to add those two digits for it to work

01/19 1+9=10 1+0=1

ratchet freak

15:39

isn't this mostly modular math shenanigans

TomMcW

@ratchetfreak Since I don't know what modular math is, you're probably right

ratchet freak

if you add all digits recursively until you have 1 digit you just got the number mod 9

a+b mod 9 = (a mod 9)+(a mod 9) mod 9

TomMcW

@ratchetfreak Ah... you are correct. I think you and Dan have solved the riddle

ratchet freak

and 18 mod 9 = 0 which has a few interesting properties

TomMcW

@ratchetfreak Maths be over my heddd!!!!

ymb1

15:53

@TomMcW just noticed this message, now it is interesting :D

ps little arrow :D

in case it was missed: a blatant copy & paste from Wikipedia for the tag info is acceptable, right?

Dan Hulme

no

there's a specific edit rejection reason for that

ymb1

good to know, only got 2 tag infos under my belt

I'll go and fix :)

does that read well for the CRM tag: CRM (crew resource management), is a set of procedures that ensure the crew are working together without any barriers, as opposed to an authoritative pilot-in-command.

anyway fixed both

@ymb1 I believe a link to the article where you copied from is enough

ymb1

16:08

cool

TomMcW

Have they confirmed that what the plane struck at EGLL was actually a drone?

If so it's the first one. Eventually had to happen.

ymb1

@TomMcW no updates here avherald.com/h?article=4970605b

no recent hits from google news

TomMcW

Only other reported drone strike turned out to be a bird.

Dan Hulme

only if by "drone" you mean "multirotor"

there have been collisions between manned airplanes and remote-controlled aircraft before

TomMcW

@DanHulme Is there another one? Hadn't heard

@DanHulme Recently?

Dan Hulme

16:14

I read an accident report last year about a collision between a GA aircraft and a (powered) model glider

the GA pilot thought it was a bird strike at first

(I can't remember whether he found out himself or if the model operator came forward)

ymb1

can they jam the drone radio freq range around airports? if it gets serious I mean

TomMcW

Doing some "droning" myself this afternoon. Technically, if I fly a model helicopter in my back yard I have to get ATC clearance first. My house is about 100 yards inside the class E for KMKC

Dan Hulme

@ymb1 Probably not without disrupting other communications.

e.g. anything that operates on 2.4 GHz can't be jammed without also taking out everyone's Wi-Fi

TomMcW

@ymb1 While studying for my drone license I've done a bunch of reading and have come to the conclusion that all the drone furor is mostly the media blowing it out of proportion.

@ymb1 The drone I fly has geofencing built in

ymb1

if I'm raising homing pigeons, do I need a license?

:'D

it's a common hobby around here, they sell for a lot of cash

TomMcW

16:19

@ymb1 If you can raise passenger pigeons I'll be impressed :P

ymb1

@TomMcW didn't this prince dude have passenger falcons :P

I saw it here in chat

TomMcW

@ymb1 Passenger pigeons are extinct.

ymb1

@TomMcW was just googling it to get your reference :D

I want to raise a FL400 goose

TomMcW

The wiki page on them is interesting. They went from being possibly the most numerous warm-blooded animal on earth to being extinct in like 20 years

@ymb1 BTW, you ruined my joke by changing it to homing pigeons :P

ymb1

@TomMcW didn't mean to :( but they're also called messenger right?

TomMcW

16:23

@ymb1 Yeah. Same difference

ymb1

collectively, humans tend to have no regard to anything else but the very near future / needs

TomMcW

@ymb1 Very true

ymb1

TIL DC-8 had slots instead of slats, like this aviation.stackexchange.com/q/32552/14897 but nearer the LE

I was like: heeey, wait a second, I came up with that hehe

airliners.net/photo/United-Airlines/McDonnell-Douglas-DC-8-71/…

can be seen opened here ^

TomMcW

@ymb1 Interesting.

ymb1

a .net thread about it airliners.net/forum/viewtopic.php?t=735021

TomMcW

16:28

Not very big, are they?

ymb1

no, they were an afterthought to improve the slow speed perf

weren't originally planned

TomMcW

@ymb1 Wonder why they aren't used any more

ymb1

@TomMcW my guess they weaken the wing if there were to be implemented spanwise

slats do the same thing but smarter

and of course they would reduce fuel carrying capacity

TomMcW

@ymb1 As long as you don't deploy them during cruise

ymb1

:/

Investigators believed that 727 pilots (in general, and this flight specifically) were setting the trailing edge flaps to two degrees during high altitude cruise, while at the same time pulling the circuit breaker for the slats so that they would not activate. This configuration was rumored to result in increased lift with no increase in drag, thus allowing more speed, higher elevation, or decreased fuel consumption

Dan Hulme

16:36

gah

TomMcW

Of course he denied that's what he did

ymb1

Hey Jim / yes captain? / let's circle for 30-minutes / why captain? / the CVR has me asking you to pull the CB / -.-

TomMcW

@ymb1 Try this one

it's spam

Pondlife

16:59

@ymb1 That's what I guessed too, but it wasn't blatant: there's no price, link to a website, "for sale!" stuff etc. So I decided to give him the benefit of the doubt and a polite hint in my comment

Dan Hulme

@ymb1 I agree with you. It's a spam seed or a bot that doesn't know how to do links.

ymb1

flagged as such and VTD

18:27

the distance between MLG wheels is called track, right?

the track is very narrow on this bird, reminds me of the Wildcat

(source)

looks nice though

TomMcW

18:49

@ymb1 Reminds me of F-16

ymb1

19:34

@TomMcW agreed

Runway torn up as plane takes off

one comment though, I wouldn't call that a take off :D more like an albatross trying to fly

TomMcW

19:51

@ymb1 The good old gooney bird. I guess that's why they stay aloft so long. Took so much effort to get up there they don't want to land.

@ymb1 They cut off the video. Did that jet clear those trees? Looks like it was going to be pretty close

TomMcW

20:08

@ymb1 The picture you put in this answer might explain why I felt the rudder pedals were backwards while taxiing. Gave me a bit of trouble and gave the instructor a very brief scare

ymb1

20:27

@TomMcW makes sense, as if the axis of rotation corresponds to the direction

some acft have the throttle/thr lever 'backwards' too, fwd is idle, aft is full pwr

I think they were Italian planes, can't recall the era

TomMcW

@ymb1 In the air it felt completely normal. I'm not sure why my brain interpreted it differently on the ground. I guess because it was nosewheel steering. If I just kept the rudder in mind I would be ok. I did scare the CFI for a brief moment on a take-off roll where I was drifting left and corrected further left.

ymb1

20:49

not sure if this is a dumb question, from this answer:

5

A: Does taxiing time gets considered in a pilot's flying hours?

Yes, taxi time is considered as pilot hours because even though the airplane is not flying actions by the pilot are required. Basically, the US rule is in FAR 61.51 (e) Logging pilot-in-command flight time. (1) A sport, recreational, private, commercial, or airline transport pilot may ...

it reads When the pilot is the sole manipulator of the controls of an aircraft for which the pilot is rated

1) what about PF and PM/PNF? 2) what about A/P 3) 1 & 2 relate to jetliner flying for my curiosity

does the PNF not log time? do both not log when A/P is in control? of course not

but the wording is weird, for me at least

scratch that... title is Logging pilot-in-command flight time

ma bad

ymb1

21:54

this was a nightmare to edit aviation.stackexchange.com/q/37656/14897

it sucks when you have to fish the question to put it in the title

hunt for*

ymb1

22:14

correct me if I'm wrong, that question I linked, the illustration (which is very good), aren't the bottom two examples identical? regardless if one set is co-axial and the other set is separated?

either way they're counter-rotating

what's the difference?

Shalvenay

@ymb1 re: the drone thing -- I think it does get blown out of proportion as well. it'd merely be an expensive quad totaled for the quadcopter operator and an expensive unscheduled engine maintenance for the airline, most likely

ymb1

@Shalvenay hey there

it was @TomMcW who said that

Shalvenay

yeah, I just wanted to toss my point in, sorry about that :)

ymb1

@Shalvenay no I meant to grab @TomMcW 's attention in case you tagged me by accident

sorry

@Shalvenay and agreed yes, like birds

TomMcW

22:34

@Shalvenay Yeah. They're creating a problem where there isn't one. The rules that have been in place for years - no flying above 400ft and within 5 miles of an airport - are plenty of margin. The problem is people who don't know or don't follow the rules. Making people register a 3 lb toy quad is just silly. Are they going to make every bird larger than a wren register? If you're flying something that would really do some damage I can see it, but 8 ounces?

ymb1

@TomMcW don't tell anyone about the goose I'm training to break that other goose's FL400 record

TomMcW

@ymb1 If you fly that goose over here you have to register it. Oh, and if it's a Canada goose it must go through a TSA background check

ymb1

lol

TomMcW

FAA came out with a terribly misleading report with a sensational headline. A couple of people have gone through that report and it appears the only drones on it that actually caused a serious encounter were military.

@ymb1 I think geese are VFR-only

There was a story in flying magazine (I think) about that. Birds avoid IMC whenever possible

ymb1

@TomMcW looks like a job-creation thing (FAA—Drone thing)

@TomMcW re IMC, makes sense

at FL400 they are flying well above the wxr though

TomMcW

22:45

@ymb1 There's always towing CU. Those can hit FL600

ymb1

?

TomMcW

@ymb1 Not sure if it's job creation. But the upside of the FAA regulations is that it preempts local bans, etc

ymb1

last two messages not clear sorry

TomMcW

@ymb1 Sorry. Towering cumulus or cumulonimbus clouds can hit 60,000 feet

ymb1

are those's CB?

got it

one Cu, the other Cb

what do you mean by "upside of the FAA regulations is that it preempts local bans"?

TomMcW

22:52

@ymb1 And the FAA regulations will prohibit local ordinances about where drones can fly, etc. They can pass laws against things like harassment, etc. But they can't do things like banning drones within city limits.

ymb1

@TomMcW you mean since on the federal level drones are okay but not near airports and require licenses, then by extension to that drones are okay in cities?

TomMcW

@ymb1 Here's the FAA opinion on the matter: faa.gov/uas/resources/uas_regulations_policy/media/…

ymb1

no TLDR version? :D

TomMcW

@ymb1 It basically says, "we'll handle this."

ymb1

what's this? :D (don't hate me)

it's 1 AM

TomMcW

23:03

@ymb1 They're saying drone regulation is federal territory. Local and state can butt out! LOL Go to bed! I've got to go fly a drone. (not near an airport)

ymb1

@TomMcW so the upside is it will be a uniform law all around right?

downside is? over regulation?

TomMcW

@ymb1 Exactly. Sorry to drone on about it :D

ymb1

Alitalia filing for bankruptcy, is the deregulation really hurting the big airlines (those that are not low-cost focused)?

@TomMcW :D
