Pakistan airline admits taking extra passengers in aisle

She told me it's a calculated risk to put passengers in the aisles.
But, the captain of the flight knew exactly what was going on and made the decision to proceed. It sounds like this PIA flight crew concealed their overloading from the captain. THAT is a very serious infraction indeed.
The pilots use weight/balance to calculate things like range, takeoff speed, altitude ceiling, stall characteristics, and so forth. If the plane is heavier than they think, that's not good.
Filling the aisles with people would be a more significant concern, but as another commenter noted, it's a calculated risk - better a long takeoff and rollout than leaving probably one or two hundred people to the tender mercies of the revolutionary and explicitly anti-Western new regime.
In either case, severe turbulence is a much more critical problem. If it happens, some people are certainly going to be badly, maybe lethally, injured.
The PIA stunt was especially dangerous due to it being a normal flight
"Billy Mays here!!..."
(granted that was a freak accident but if you're in a vehicle with a seatbelt you should wear it)
This comment sent me on a journey to find obesity data on Ethiopia and I found this ranked list that tied back to the CIA factbook as source and places them next to last (currently): http://www.indexmundi.com/g/r.aspx?c=et&v=2228
Keeping the cargo secure and the wrench that extra passengers throws into emergency procedures is the real issue here.
Still, it's a bad idea to prang an airplane with a few hundred people in the aisles, so pilot skill is important.
When I was in India it was common to have people sitting in the aisles on long distance buses, trains, and theatre halls where fire evacuation plans were clearly not being followed. Agreed, planes are not theatre halls, but how severe of a breach in public safety is this? I think planes are a special case because they are such fragile systems, but it does seem like in the West we worship health and safety a little too much.
Speaking of theatres and other venues, overcrowding them is way worse. For once, they actually do catch on fire much more often then planes fall from the sky. I consider overcrowding a theatre criminal negligence, while I couldn't care less about (minimally!!) overcrowding a plane.
Such an over-crowded flight would have caused
problems in an emergency evacuation, aviation
experts said, and passengers would not have
had access to oxygen if it was suddenly required.
Additionally, you don't wear a seatbelt on a plane to save you from a crash, you wear it to stop yourself being injured during turbulence, or from injuring someone else by being thrown onto them. Obviously these people did not have seatbelts.> And the seat belts that flight attendants urge you to wear during most of the flight also helped to keep head and neck injuries to a minimum, says Dr. David King, a trauma surgeon at Massachusetts General Hospital and an assistant professor of surgery at Harvard Medical School. “Clearly for the vertical deceleration [typical] of an airplane crash, the lap belt seems to be the most important restraint,” he says.

> "between 1983 and 2000, more than 95 percent of people involved in U.S. plane crashes survived."
Similarly, I take off my shoes during long flights, but make sure to have them on for take-off and landing, in case of evacuation.
An Air Canada flight in 2015 had 21 people injured, including a broken pelvis.

Again, we don't have standing room planes for very good reasons. And breakdowns in safety protocols should be worrying. But as a one-off event, the incremental danger is actually pretty slight.

Otherwise, totally agree: compared to total number of flights (there's maybe 1000 B737 and A320 in the air at any moment), rare (though potential consequences could be grave.)
And, as you say, it's the negligence of basic safety protocol that's worrying.
First, as we started to descend I instinctively went back to my seat and buckled up. But I noticed a lot of the other "frequent flyers" were still up and walking around. So I asked one of them, "When are we supposed to sit down?" They just kind of laughed at my "noob question" and said something to the effect of-- "You don't really have to sit down at all just watch how the pilot lands this thing." So people were still up and walking around as the plane landed. For someone who had only flown commercial it was a fascinating to me for some reason. Sure enough- the pilot put her down like a feather and came to a gentle stop.

(Under part 91.107 [1], where part 91 are general rules for general aviation, and that rule does not hold for operations under part 121 (air carriers/airliners), 125 (planes with more than 20 pax), 135 (commuter and on-demand flights), but they all re-introduce it separately [2][3][4], so yeah.)
Either they're all criminals, or the rules on military flights are different.
At any rate, I'd think it's rather prudent to sit down and put a seatbelt on - the rule's not just for fun, but because accidents can occur. The notion that the Airforce One pilots are somehow special with special landing skills strikes me as fanciful.

1. AF1 is a 747. If you've never been on a 747 (or A380), then you might not appreciate how smooth landings are in general. It's a lot of airplane with a lot of momentum (not to mention a lot of electronic assistance for the pilots).
2. You say "The notion that the Airforce One pilots are somehow special with special landing skills strikes me as fanciful." I don't consider that notion fanciful at all! In fact, I'd expect they have special landing skills. The AF1 pilots are not just some random commercial or charter pilots, they are Air Force officers, hand-picked from the best of the best. In addition, not only do they have to take-off and land the president's airplane, they also must be able to take evasive action IN A FREAKIN' 747 in the event of a hostile encounter. So "special landing skills"...I'd buy it.
EDIT: Also, reading the original Quora answer, the particular landing mentioned was on the Shuttle Landing Facility, one of the longest runways in the world! I'd wager the pilot could've practically let AF1 roll out the landing and had room to spare.
But are you advocating that pax in an A380 approaching big airports with nice weather just walk around as they please? And why not? Because the risk during takeoff and landing is elevated, compared to cruise flight, isn't it?
It's a tricky question, granted, but I'd still say, "principiis obsta", nip things in the bud, don't let safety standards slide, buckle up.

Imagine people trying not to fling around the cabin when hitting a rough patch. This isn't something that happens on a bus, but it is routine in aircraft.
I mean, this can happen on a bus: http://stream1.gifsoup.com/view3/2175405/bus-bounce-o.gif If you experienced proper turbulence in flight, you can imagine how it can go wrong on a plane. So around 8 and I will call the staff if you sit next to me and think you're too cool for the seatbelts.

Google tells me that the average person weighs 80.7kg, let's conservatively round up to 100kg to take into account clothes, and luggage (It's probably higher). From this we can estimate that the PIA flight had an extra 700kg (It's probably closer to 1 tonne) of weight on board, and extra 700kg that wasn't properly secured or distributed.
Depending on the plane, the effects could range from using up more fuel (planes carry extra fuel for emergencies and so they can circle their destination while they wait to land, it would eat into this reserve making flight incidents more deadly), to failing to take off the runway; The pilot wasn't informed until he was in the air.
While the plane in question is certainly larger and more powerful than the majority of the links I provided, the fact of the matter is an overloaded bus or train may refuse to move if overloaded, a plane can fall from the sky killing people both on-board and on the ground. Planes fail deadly.
You now have 7 extra, fragile humans standing in the aisle who have nowhere to belt down in case of emergency. If the plane crashes, needs to make an emergency landing, or even encounters incredibly rough turbulence they could be thrown around the cabin hurting both themselves and others.
As for a 1 to 10 scale of transgression, it's hard to place because of the nature of such a simplistic scale. Assuming your scale is confined to aeronautics (lest we invoke Godwin's Law) what counts as a 1, and what counts as a 10? If your 1 to 10 scale is truly inclusive of every possible aeronautical incident then 1 has to be a passenger with a typo on their ticket, and 10 has to be 911. I don't know about you, but I have no idea where to place this overloading incident on such a scale.
While the plane in question is certainly larger and more powerful than the majority of the links I provided
At least an order of magnitude more.
https://en.wikipedia.org/wiki/List_of_airliners_by_maximum_t...
The smallest 777 can take off weighing over 200t. An extra 0.7t is basically nothing, considering even the smallest variant holds nearly 100t of fuel and consumes over 6t/h of it. In other words, 0.7t is the weight of the fuel consumed in less than 7 minutes of flight.

As anecdotal as it gets but still eye opening.
I hate that. Of course, most likely nothing is going to happen, but it could, and then their stupid suitcase could also fall on my head.
When the plane arrives at the gate, there's still plenty of time to get your stuff... :-/
IMHO the weight difference will be negligible, and in an emergency evacuation those in the aisle would be the first to leave. The biggest risks are probably turbulence and availability of oxygen.
The moment arm ("virtual" fulcrum) is an imaginary point where the balance of the plane is and it moves depending on the shape of the aircraft and where the weight is located.
Imagine a long lever with the fulcrum in the middle now imagine that lever is flying in three dimensions. Any weight near or far from the fulcrum makes it difficult to control the lever (aircraft) if the weight is moving or in the wrong spot.
My flying lessons were 25 years ago and I didn't continue but that's the gist of it.
My instructor even made me secure my pen when I was flying nothing loose in the cabin.
For the pen, there might be other reasons - a dropped pen might slide under the rudder pedal and block it, or interfere with other things in the cabin.
Turbulences injure people all the time, see [1].
Also, commercial aviation is as incredibly safe as it is because everyone follows the rules. If you start neglecting them because everything is happy and dandy nearly always, you are contributing to the next accident.
It is this creeping "normalisation of deviance" that has to be fought.
Note that generally I agree with the notion that we might exaggerate with safety - I'm all for letting children play, for example. But here we are dealing with potentially deadly consequences, and not only for yourself, but for others.
Let me conclude with a great quote:
> "Aviation in itself is not inherently dangerous. But to an even greater degree than the sea, it is terribly unforgiving of any carelessness, incapacity or neglect."

heh...Aeroflot
1. They are labors. and they can't miss the working day, they beg to fly in aisle
2. 99.9% is above, other than some religious pilgrims, who have tight schedule ...
3. PIA is dirt cheap for Karachi to Medina compared to ahem Emirates
And it wasn't as uncommon than one could think, until recent times, few decades ago, it was pretty regular thing for Karachi to Lahore (local flight ... 1 hr approx) ... as people have to meet certain time to perform a job .... and back then there were no local carrier compared to dozen of them now, and about 20+ KHI to LHE daily flights.
It's terrible, but chalking it up entirely to PIA is bit unfair...
There is very high chance that it makes no difference to anyone at all. That's why it's seen as a "no big deal". I when something is VERY unlikely making it even ten times more likely doesn't matter to people's perception of risk.
And as I was saying, I understand this attitude from the passengers. For them the risk of a crash may be severe but highly unlikely and in comparison to the risk of loosing their job acceptable. But I would have expected the average HN commenter to recognize the just like the risk is different for different types of drivers (and their cars due to maintenance) , the same applies to planes. So those less rare events may be more likely than the average.
So making some events (and their consequences), that may already be more likely than the average for them, a number of times more likely is bad.
Than again the average is just as uninformative a statistical indicator for HN commenters as it is for drivers and planes.
This makes me think, when someone talks about something they perceive as the average of something do they perceive the median, the mode or actually indeed the mean(average)? There is a case to made that we actually perceive the mode (value that appears most often) instead of the mean.
Being sloppy with crew rest, sobriety, maintenance schedules, would make me much more nervous - and the people in the aisle might indicate a bad attitude.
I don't think you understand that "risk" doesn't mean "damage"?
It is actually irrelevant in this case how risk is actually calculated from these two because almost no one actually calculates it before a plane ride. (Though it is probably calculated for heads of state/royalty/CEOs/etc..)
Maximum certificated escape capacity for a 777-300ER is 550.
"As many as seven passengers aboard the Pakistan International Airlines flight PK-743 (Karachi-Madina) on Jan 20 were forced to stand throughout the over three-hour flight after the airline boarded excess passengers in a serious breach of air safety regulations."

Doesn't sound believable...
Don't put spaces before commas or question marks.
Single question mark is enough. "??" looks sloppy.
Actually, I do this all the time, when what precedes the punctuation mark is a URL. It just doesn't seem right to have the URL seamlessly run into a punctuation mark that isn't actually part of it.
Another possibility is to put <> around the URL; but that didn't work correctly on HN last time I tried.
You can identify texts written by French people by the extra spaces (if they're careful or have a good word processor, it'll even be a non-breaking space).
PS: Spaces before smileys also permissible :-)
Not sure how's that relevant to this article, though...
