Okay so from my (limited) knowledge of aeronautics, at high AoA turbulence is generated behind the wing which eventually results in a stall, would this turbulence have any effect on the engine performance due to how close the intakes are to the backs of the wing?

You've got it mostly backwards. Turbulance is "one thing". Turbulant air is "another thing". Stalls can be predicted by turbulent air flow, but are not defined by it. A stall is what happens when the airflow over a surface separates from that surface. The air "under" the separation is going to be turbulent.

I assure you the designers considered wing and fuselage effects on engine placement on that plane. However, it's not uncommon for jet aircraft, in general, to have engine issues when airflow is coming at weird directions. "weird" can be defined as anything more than a few degrees off the axis of the intake.

Cross-quoting from the OSHA thread:

Sanctum posted:

Well this is not supposed to happen.



When a plane pushes out it's being backed out by a tug and guided by wingmen to make sure the wings stay clear of anything. The wings are always supposed to be treated like they have a zero height clearance. You don't make judgement calls about height clearances; everything must be fully clear of the wings. Each gate has an 'envelope' that the wingmen are supposed to make sure the wing tips stay inside of when going in/out.

This particular wing is going outside of the envelope, extending over a slip, then ACROSS A SERVICE ROAD, ACROSS ANOTHER SLIP WITH VEHICLES PARKED IN IT, INTO ANOTHER GATE'S ENVELOPE, AND OVER THE WING OF ANOTHER PLANE. What the picture doesn't show is that the 787 pushing out is still moving. That's right, dude didn't even stop. Wonder what that pilot had to say about that. :gonk:

"Fine" is a bit of an overstatement. CRJ-705s and the like are better, certainly, but I'd still rather fly pretty much anything else. It really depends on how long the flight is; I'm fine for an hour or two, but gently caress Air Canada for running CRJs on YYC-IAH. That's far too long (nearly 4 hours) to be on such an aircraft. I would take E170s or E190s every time over that.

I haven't been on one, but I'd imagine not. Still, their maximum capacity is well below that of the "long" CRJs, which are more comparable to the E170 in terms of capacity.

To jump back on boarding pass on phone chat, I do recall one issue that my fiance ran into. I have TSA Pre-Check, and she does not. When she did the online check-in, her boarding pass showed TSA Pre-Check. When we got to the front of the line (DEN), the lady told her that she did not actually have Pre-Check and would have to go back to the normal line. Thankfully the lady up there let her use the Premier line. All around a confusing experience; not sure if a paper ticket would have made that any better.

My guess is that the TSA pre-check status was getting stored in the database as a property of the reservation, not a property of the individual boarding pass, because a software developer or database administrator did a stupid thing at some point.

EDIT: ^^^^ That works, too.


How do they tag hand baggage with "cabin baggage allowed" tags prior to the flight? It would be exactly like that, except these are ones that you pay for at check-in instead. How would this be even slightly difficult? It's easier than everyone trying to bring a "slightly" oversized roller-bag and dealing with the resulting Tetris. People would spend less time standing in the aisle, boarding times could easily be cut in half I imagine.

Most of the time they don't waste time with the "cabin baggage allowed" tags unless you fly lovely cheapskate airlines who will rear end rape your face for a nickel but okay, let's say they are now 100% used everywhere in your fantasy land. How do they now enforce that you aren't putting an unauthorized bag overhead? Have the cabin crew examine everything as it goes up? Examine every bag before they close the bin, including pulling down every bag without a visible tag to inspect it? How do you handle bags within bags? How about coats? How do you combat tag reuse by the same person? How do you prevent tag theft? Keep in mind that you can't add much extra time to boarding and that you have to make money from this whole thing.

Like, uh, British Airways on a Club World ticket? They do it so that the tagged item is guaranteed in the cabin, with the provision that it must be placed under the seat in front of you.

There's already a flight attendant welcoming people on board, they can visually check that all hand-baggage is properly tagged at the same time as they look at your boarding card and direct you to your seat.

Also, if there's some level of fraud, that's still better than the system that exists now, where boarding takes forever and there's never space for anything in the overhead bins. It doesn't have to work 100% of the time to represent a really, really big improvement over the current system, and a massive new source of funds for airlines.

No...the thing is that apart from a few cases NAV Canada is spending huge amounts of money rolling out RNAV and RNP approaches at as many airports as they can...ILS is slowly starting to go the way of the NDB and (increasingly) VOR. It will be used in a few select applications still, but RNAV and RNP is the way of the future.

Not that any of that would have made a difference for that A320, as it was one of the few A320s at Air Canada that did not have GPS installed (if what I read is true, that is...)

They aren't going to deny boarding to someone who hasn't got a tagged bag though, or go through the even more complicated and time consuming step of gate checking it on the jetbrige either. Not to mention passengers connecting from other airlines who might not have a tagged bag.
In addition to this, you're looking at it from a passenger convenience angle, which is fair enough, but turn times are generally not limited by the time it takes to board the self loading freight.
It doesn't matter if it takes 20 minutes or 40 minutes to get everyone on board, the aircraft isn't leaving any earlier. This is especially true in places like Heathrow where the departure slots are so strictly controlled. As long as it takes less than 45 minutes or so to board a widebody or 20 minutes on a narrow, it all works out fine. When there's delays on a minimum turn, it's usually not because of passenger boarding, unless there's some no-shows and they need to pull their bags.

If you don't have a tagged bag because you're connecting from another airline, they can let you pay on the plane during the flight, just like they do if you'd like something to eat. And, like I said, if it doesn't work 100%, we're still better off than if we just let people jam all of creation in the overhead bins, as appears to be the current system.

It's clear you just don't like this idea, probably because you don't want to pay for overhead bin space. That's fine, but don't pretend that charging for overhead bin space represents some insurmountable logistical issue.

If a narrowbody could be turned in 20 minutes, it wouldn't be necessary, but most recently, my flight began boarding 40 minutes prior to the stated departure time and it left the gate after schedule. If we could get it down to 20, I'd agree no changes should be made. Mainly because people loving with the goddamn overhead bins gently caress everything and everyone else up.

Uhhhh except they can be? Just because it happens to you once doesn't mean that it is anything near approaching the norm.

When I worked on the ramp for a major airline going through college, our average turnaround time on their 120-150 seat narrowbodies was under 30 minutes. It can be done in less than that easily too depending on the type of passengers too...turns flying oilfield workers on a similar type can be as short as 15-20 minutes.

Well yeah, they can be, but they aren't, and at the moment the limiting factor is passenger boarding time (and likely de-planing time too), which is why it's possible to go so fast when you have passengers who know what they're doing. That's why it would be beneficial to limit things that result in long boarding times, like passengers with large quantities of hand baggage.

It isn't though. Even if you could get everyone on board instantaneously, the limiting factors are maintenance, servicing, catering, cargo, fueling, crewing, and pilot prep, much of which happens during boarding. Whether your boarding begins at 40 minutes prior to departure or 20 minutes prior to departure makes no difference to the departure time, which took all the above factors, including boarding, into account. The difference to you is how long you're waiting at the gate before they commence boarding proceedings, which is entirely arbitrary because you're waiting at the gate anyway. That's why I said it amounts to a convenience issue. You're perceiving it as "oh God, I had to queue for 15 minutes before I got on board, and when I did, there were all these people trying to stuff the overhead compartments full of their poo poo". The airline sees it as aircraft arrived on time, turned on time, and pushed back on time, job done.

Consider, on an industry-wide scale, is it really the root cause? I'd say there's plenty of evidence it's not: Linedance's post is an excellent example, and the fact that airlines like fast turnarounds and can change whatever policy they want to screw you because they've got what amounts to an essential service.

There was room in the bins, it's just that the tag meant there was no possibility on either the Club World segment or the connecting Club Europe segment, that I'd have to gate check the bag.

There's plenty of airlines in Europe that restrict hand baggage to increase turnaround speed. Fine; perhaps there's no feasible way to charge for overhead bin space, but the general principle is sound in terms of reducing boarding times. Maybe Air Canada is especially useless, but I watched them take 40 minutes from the time the first person stepped on board until the door was closed, twice in a row. I've seen BA board the same type in 20, boarding from both sides and with a more sensible hand baggage limit. Therefore I have deduced that, in this case, passenger boarding is the bottleneck in turnaround speed.
