sticks, but it's fly by wire, they're basically computer mice, if they're moved simultaneously in the same direction the input demand will be algebraically added to a certain limit, if moved with equal input in the opposite direction the input demand will be cancelled, either side can lock out the other

To the layman, that sounds pretty dangerous.

Yes. And they still suck. It was a contributor to the Air Asia crash a couple years ago.

that was a problem with the rudder travel limiter, and no, they didn't replace the sticks

tremendous amount of redundant backup flight computers with protection laws for speed, pitch, and bank, you can disable almost all of the flight computers and still have controllability to allow you try and reboot them, restoring just about any one of them gives you back a flyable jet

no one killed, only a minor injury or two during the evac, heck yeah, you can always get another airplane, there's been quite a bit of data collected that indicates he may have had a better chance of making it back to the(an) airport that it appeared to be, but put in that position, with what was at stake, I think he made the best choice to give everyone on that plane the best chance for survival


This right here. Could he have made it to an airport, maybe, but if you don't, everyone dies, including folks on the ground. The Hudson provided him a place to set it down as gently as possible without a runway.

The United Express crash in Buffalo a few years back due to icing on the wings was terrible to listen/read. Both panicked and likely could have performed some controlled landing that would have been less devastating.
You mean the Continental Connection crash (Colgan #3407 on 02-12-2009)?

Flight Crew:
Captain Marvin Renslow, 47, was the pilot in command and Rebecca Lynne Shaw, 24, served as the first officer.

Captain Renslow was hired in September 2005 and had accumulated 3,379 total flight hours, with 111 hours as captain on the Q400.

First officer Shaw was hired in January 2008, and had 2,244 hours, 774 of them in turbine aircraft including the Q400.

I've read a ton about this incident.
Without knowing how much damage he had really taken and how much thrust he was going to have, it was an imbalanced risk to try to head back to LGA vs putting her down in the Hudson.

The immediate decision to hover the Hudson while trying to buy time to recover thrust and maybe get to TEB was excellent. When he never was able to recover, he had already established an acceptable solution.

I know this is one of the most interesting simulations for pilots to run, but without hindsight and having to deal with the immediate pressure of the situation... I wonder how many pilots would actually choose the airport option.

Wow. We flew to NYC this summer and seeing the skyscrapers and then the Hudson all I could think of were 9/11 and Capt Sully.

A Letter to Mr. Clint Eastwood

Dear Mr. Eastwood,

I just wanted to thank you for using your talents to direct the movie “Sully,” which just opened in theaters in the United States. However, I wanted to highlight that although I am not co-starring alongside Tom Hanks and my “face” is not in any advertisements, I played a key part in helping Capt. Chesley Sullenberger save the day on that cold New York city Thursday back in January 2009.

Allow me to introduce myself. My name is 131-9A Auxiliary Power Unit (APU), U9A for short, and I live in an obscure area in the tail section of the A320 airplane, and many other models. My family, Honeywell, is known for being the market leader when it comes to APUs, so they’re very proud of the role I played in that scary, but miraculous event.

After the plane flew into that flock of geese, both engines were badly damaged, so the generators couldn’t provide sufficient power. That’s when I stepped in and provided the power needed to keep the flight controls, displays and envelope protections temporarily in place. If it wasn’t for me and the captain’s smart instinct to turn me on, “Sully” wouldn’t have been able to land that Airbus A320 in the Hudson River at the lowest possible airspeed and save all those lives.

Just talk to my friend, Flight Recorder, she recorded the whole thing, or take a look at page 88 of the NTSB report. It clearly gives me credit:

“Starting the APU early in the accident sequence proved to be critical because it improved the outcome of the ditching by ensuring that electrical power was available to the airplane. Further, if the captain had not started the APU, the airplane would not have remained in normal law mode.”

Now I’m not saying I deserve all the credit, because “Sully” is a very talented pilot, Tom Hanks is a heck of an actor, and it is very obvious that I could not have done this without a pilot. However, I do think the world needs to hear more about my part in the story. So, I’d appreciate it if you could make a sequel. Perhaps, we could call it “131-9A” and I could be voiced by Anthony Daniels? I just love him as C-3PO in the Star Wars series! (And if you don’t mind I’d really like Tom Hanks’ autograph).

Sincerely,
Honeywell’s 131-9A APU

131-9A APU



Just sayin'

You're an attention whore.
