I would like to know what the Ryanair pilots are ordered to do by their higher ups. Been on a few of them in Europe and they all hit the runway pretty hard coming back down.

Navy pilot vs Air Force pilot.

Ryanair is not exactly recruiting from USNavy

Isn’t there some sort of reset settings button when you start a new flight? Like is there any setting set by the previous crew that should be left as is by the new crew?

Most of the switches are physical selectors and dials that aren't motorized so it would be impossible to reset those. And a partial reset would probably be even more confusing.

The flight computer isn't controlled by physical dials, and that's where you do pre-flight calculations (including the V1 and V2 speeds for given takeoff mass)

I've heard Royal Air Maroc is pretty good when it comes to African carriers but I'm not sure. I know they have (or at least used to have) experienced crews and good airframes, but I don't know anything about their maintenance standards

Royal Air Maroc had a senior captain bounce an ATR-72 off the surface of the ocean through pure bad flying in 2018. Literally the belly of the plane scraped the ocean. Basically avoided killing 50 people by a few inches. Wasn’t gonna report it, but the damage gave him away. Look up air Maroc flight 439

> - Has lower-level officials that accept bribes How many countries does that leave? And why only low level, why not also high level? Doesn't that rule out the US as well? > - Has had airlines and planes for fewer than 5 decades Also sounds arbitrary.

I am expat in south east asia and his comment is correct low level officials taking bribes means you can do stuff like never wear a seatbelt, just pay the cop $20 USD if you get pulled over. get pulled up for smoking indoors? $20 USD. run over an illegal immigrant and kill them? USD 1000 to have their records completely erased. Sim card? $5 USD cash. rape? what? the police here hung up on my friend on a 911 call beca…

It's unbelievable that the pilot's didn't realize they were doing 215 knots while still ON THE GROUND and only decided to pull back on the yoke once they were nearing the end of the runway. They should have at least seen the end of the runway coming up and wondered why they weren't airborne yet. The ends are colored in amber and red as it gets closer to the end, it should be pretty obvious something is wrong. Pull ba…

I thought all takeoffs were manual. Is auto-takeoff out of testing already?

They are, but there's a system that almost shouts "VEE ONE!" and "VEE TWO!" over a loudspeaker in the cockpit, at least if the flight director is configured properly.

I'm grossly simplifying but V1 is the point where you go "okay, are we SURE we're ready to go flying, y/n?" Around V1, if there are problems with the plane not conducive to flying (engine failure, fire, control surface malfunction especially), you reject the takeoff. On a loaded/fueled commercial jet you run a chance of tire/brake damage because the braking system will be at nearly its limit, and the heat might cause some of the thermal/pressure fuses in the tires to blow.

At V2, that's where you are going flying whether you damn well like it or not, with the only exception being (I believe?) a loss of control surface authority, because in that case, you're not flying, period. Plane on fire? You're going into the air, because if you don't, you're crashing because the plane won't stop before the end of the runway.

Then there's Vr, the point at which you go flying (rotate.)

Just about the only thing on the pilot/copilot's mind around V1/V2 is "does everything feel / sound / look OK?" and then getting as much altitude as quickly as possible once Vr is hit, because altitude is potential energy. Until you have enough altitude such that your glide distance is enough to circle back to the airport and land, you are completely boned if you lose both engines.

The runway is long enough to handle the plane rolling out from V1 to a stop. That means at Vr you aren't anywhere even remotely close to the end of the runway.

Going into the runoff area, but then also failing to climb at a normal rate even after you've finally taken off, is mind-blowingly incompetent. I would think it would almost be a career-ending mistake for both officers. If the first officer was flying the plane but the captain was PIC, the captain should have taken control a second or two after the first officer failed to rotate at V2.

My guess is that the captain was flying and the first officer didn't speak up; especially on the least desirable route people are looking to get promoted out of that hell, and arguing with the captain often isn't conducive to that. Lot of the captains know each other, and even if you get promoted, you stand a good chance of running into one of his buddies.

Edit: forgot to mention, the plane was likely screaming at them for overspeed on the gear and/or flaps, as well.

I'll play devil's advocate and suggest that it is a systems error that the 777 accepted an altitude of 0 without sounding an alarm or at least requiring prior confirmation. It shouldn't be that easy to almost total the airplane.

Bear in mind there are airports in the world at less than 0ft sea level. Very complicated to validate what a valid input actually is

do they not have GPS and the ability to look up airport elevations on a map?

It goes way beyond checklist stuff. Imagine having an intermediate system in your Tesla, one between fully manual and the autopilot. This system uses the navigation capabilities of the autopilot to draw in the big screen some squares that guide you to your destination without the need to look outside. Something you may find in a videogame. This system is helpfull and easy to use, and allows you to pay attention to mo…

When you say an airline like Emirates, what do you mean? Are they in a certain category of airline? I’m wondering how to avoid flying on airlines who have bad practices but at present I’m not sure how to tell.

Gulf carriers in general share that reputation for bad working conditions for crews and bad safety practices.

Your safest choice is a US or EU legacy carrier. But for example in Asia you will not have that choice for local routes. Then there aren't that many things you can see on the outside. But one thing that can help is going with a large airline that also operates long haul flights into the US and Europe. There is a list for example of airlines banned from operating into Europe. You get on that list by having questionable safety or maintenance practices. So being allowed to operate flights to Europe is a small positive signal.

This! While the maintainer of the site is a "strong character", I would trust him for timeliness of updates and correctness of the information provided.

How is he a strong character? The only strong characters I've ever seen were other people in the comments, and I'm surprised he hasn't disabled them years ago.

> The article said--it's the smallest plane Emirates flies. What does that have to do with anything? The 777 is a huge aircraft. It has a maximum passenger capacity of 550 people. If you can have 550 people lives in your hands and are making mistakes like this, it doesn't matter if it's the smallest aircraft in their fleet. And before anyone bothers to point it out, I know this particular airframe was not configured…

It's the smallest airplane and a very long route which means it gets the least promoted pilots; it's the shittiest route. The article discusses this.

I thought based on how pilots were paid, longer routes were more desirable? And shorter routes would be in lower demand, since airlines don't typically pay for time spent on the ground?
