@ymb1 That article is from 2015. Has there been any more news on it?
03:20
@TomMcW does not seem to be so. heck, the KEWR GLS approaches don't seem to be capable of being used coupled below DA at all
@Shalvenay The article says 2018, so maybe it's close

@TomMcW not sure but i can look into it later today, if I had to guess, there is probably some push back, but I'll expand on that once I look into it :) (hint: similar to what I said about the early 90's and the ATN coupla weeks back)

@ymb1 could you please help in this question.aviation.stackexchange.com/questions/48120/…
@ymb1 I didn't understand the answer posted mainly the point which says sideways force. I requested the the answerer to clarify it but nothing yet.
06:54
@Jai - I saw it when you posted it, for me the paragraph doesn't make sense. the loss of rudder authority is unobjectionable, although it is much more pronounced on a plane like the MD-80. for the sideways force, I tried a theory but it doesn't hold up: asymmetric side-thrust from the reverses, the theory I had wouldn't cause asymmetric thrust, and even if it did, this force close to the CG (again, unlike an MD-80) wouldn't be that big
@Jai I highly recommend you discuss it with the instructor and you can even request a demonstration next time you're in the sim
that being said, if you don't get a reply, offer a bounty to get more attention
07:27
@TomMcW - so, the FAQ page says 2018, but this pdf (aug 2016) says mid-2019 for the "design approval", for Europe, full operational capability is 2025, with a couple of the enablers still in the works, so it's not there yet

I'm getting really tired of this guy. Sometimes I wish we weren't so welcoming of everyone: aviation.stackexchange.com/questions/48193/…
15:55
@abelenky Let him have fun. He is a nervous flyer but still flies a lot. I'm sure that the pilots and flight attendants on flights he is on, are more frustrated than you are.

I think the only way to interpret that question as on-topic for the site is "If you're an airline pilot and a nervous passenger accosts you before the flight, how do you get rid of them?"
@mins aviation.stackexchange.com/a/48196/14897 accidental wiki, or am I free to edit it substantially? or wiki just because it is low effort (not judging, question is low effort)
asking because first answer should be no, not yes, but it will take lots of lines to edit to explain
Hi @ymb1, intentional, go on.
@mins 👍 this is gonna be fun!! :D
Well the question could be interesting, but there is nothing to put in perspective, e.g. adding engines is adding drag and weight, and fuel. Without a whole picture and no cost limit, we can do anything I imagine.
@mins done :)
18:26
@mins it is interesting somewhat, but the issue is I failed to find an example where extra engines were added to shorten the takeoff distance, discounting rocket assisted C-130's. Any additional thrust comes with increased carrying capability and/or bigger airframe. The apparent examples (e.g. 747 variants), didn't add extra engines and they ended up having the same takeoff distance more or less. Anyway, thanks for the wiki gesture :)
I think the engine/wing interaction was an overlooked item by OP, which was worth noting
19:01
@mins I am aware you wrote possibly, but is there a naval manual that confirms it? reason I'm asking is this article, which says:
> Charlie, Charlie, Charlie - Security threat
19:47
@ymb1 : "is there a naval manual that confirms it?", if by "it" you mean the friendly hello to a fellow (wo)man, then no. But you probably mean something else, or I may have been unclear. This suggestion is based on usual practices, like a ham would add "73" to the greetings to another ham, emphasizing they are fellows.
19:59
@mins I see what you mean now, thanks. the new answer agrees and give context to it too, FWIW, the double actual PTT click is used in the civilian world, when the pilot can't be bothered to reply or the reply will take too much time that needed, for example:
expect late landing clearance when it is apparent, or for example delivery clearance is busy and asked you to stand-by, a double PTT click does it then
20:16
The last answer needs so explanation... I don't see how the PTT trick would translate into Charlie-Charlie rather than nto Click-Click. It could to be an unknown use of the C flag actually. I looked online, and didn't find any supporting element. Let see if some comes.

@mins the most I could find in books was charlie charlie for C&C (command and control helicopter) during Vietnam War. I also found it in the context you mention in two ATC transcripts, one of unknown origin, the other was an accident report (?), lastly I checked Flying Magazine, they didn't mention it--I thought they would even for an informal phraseology
nonetheless its origin remains interesting
@mins if you can confirm the pdf source, feel free to add it as an example
by origin I mean whether click click or naval flags, it's got to be one of those
late answer aviation.stackexchange.com/a/48036/14897 but really good, about the B-52 nacelle shape, nice historical Boeing v Convair aspect to it
I know it's been on meta.se for ages, but really a 'new answers' tab would be really good, not that 'active' nonsense
22:48
I think that answers the solo fighter pilots sleep question aviation.stackexchange.com/q/8885/14897 but I'm not sure
I recalled it from a PBS war documentary, and then found it on site :D
23:04
@Jai - see this article: Reverse thrust: Stopping with style, they have that image:
@TomMcW - i need your help with that one (above), brain fart moment, why is the picture on the right, showing a left-ward component for the reverse thrust (!)
@ymb1 Exhaust vector is forward and to the right so thrust vector is back and to the left
@TomMcW but reverse thrust force is forward (to slow things down)
the phenomena might well be there, but I think it's one of those pretty-pictures with no context (like Bernoulli when left on his own) -- but again, I'm having a brain fart moment
@TomMcW yeah, i take it back, it's backward indeed
backward and to the left, so ... yep!
@ymb1 Thrust is the reaction force
👍
they should not talk about forces and draw wrong arrows, it's late for that stuff! :D thanks for the help
@ymb1 :D
23:12
but...... here's the cool bit
upon touchdown, in the example above, the plane yaws right, which calls for left rudder to correct, soooo, the reverse in that case should help
@ymb1 Now I keep seeing that scene from the JFK movie: "Back and to the left. Back and to the left."
don't know the reference but I laughed nonetheless :D
correction: upon touchdown ... the plane will be pushed to the left, which the side will make worse
so yeah, it makes sense now
@ymb1 Oh, the movie makes a big deal about the fact that Kennedy fell back and to the left, insinuating he was shot from the front right. Kevin Costner kept showing the Zapruder film and repeating, "Back and to the left."
@TomMcW oh, don't know why I imagined an instruction for a dance move
@ymb1 You said that you thought wing mounted engines wouldn't affect the rudder as much as rear-mounted ones. It seems the other way around to me
23:21
@TomMcW how so?
@ymb1 You're prob right. Looked at some photos. I was thinking the clamshells came further back, but they are right in front of the rudder on an MD-81
OK, I think I might have just found a record for "scariest fume event ever": avherald.com/h?article=4b4623d6&opt=0
@TomMcW above always confuses me, wind is drawn arrow, source: youtube.com/watch?v=roS6oFjCDhc
and when I ask pilots about it, they give me an answer, and shorty thereafter, poof
moments later:
rudder opposite direction
but when I fly it in a sim, the reaction comes natural without thinking
@Shalvenay didn't mean to drown your post, scary indeed, new (neo) engine related perhaps?
@ymb1 Is it gusty wind?
@ymb1 : Ah thanks ymb, this is a good start for documentation. I'll add it.
23:32
@Shalvenay You hear about the E/A-18 Growler that crashed at Nellis AFB?
@ymb1 yeah, quite -- it does seem particularly severe as far as fume events go, so perhaps some design features on the NEO's engines impacted that? hopefully the NTSB can follow up more thoroughly
@TomMcW don't know, I can ask it on the site, might do so when I can present what confuses me in a good manner
@TomMcW I vaguely recall there was a crash at Nellis a while back
@Shalvenay spirit got the PW1000G one? maybe gear housing oil issue?
@mins 👌 I'll try to get the link to the first transcript I mentioned
@mins VERY long page, but it's there: cockpitseeker.com/search/altimeter I don't know the transcript's source, and parts of the page are in French
23:35
thanks
@Shalvenay This was just a couple days ago. It was an Australian AF plane
too soon to tell anyway
@TomMcW ah, during Red Flag
what was that chat room @Federico (?) keeps telling me about for the spam-handlers?
or maybe it was @DanHulme
23:48
@ymb1 : Good, thanks for this other one. Both included --> aviation.stackexchange.com/a/48185/3201
at least the crew's OK re: the Growler. wonder if they had some sort of weird malfunction on takeoff?
@mins looks good (Y)
@ymb1 spam flag planted :D
