Boeing aircraft sales slump to historic lows after 737 Max annus horribilis

Re: Accountability

thanks, yes. it just adjusted the stab trim.

Re: Accountability

Have any angle of attack to pitching moment graphs from the 737-MAX been released?

Does it have a sudden change in pitching moment?

robin48gx

Re: Accountability

MCAS. Did it drive the trim, or just load the column? I was under the impression it moved the stabilizer trim; but reading other stuff, it seems it was altering the control loading. I guess hitting the stabilizer would have the effect of loading the column anyway, but I'd like to know the full/real story.

Have they re-classified the simulators? What level is FAA Phase 3 from say 1990?

Re: ...

CFM56 ?

robin48gx

Just a guess really. I did see some flight simulation code that had a bug like that. If you flew directly over the north pole (and were unlucky) you miraculously appeared at the south pole and visa versa. Grown-ups should really use quaternions...

robin48gx

not if they only checked for 90 degrees and forgot 270

270 degrees ?

hmmmm

Prob not faa certified

When I worked on SIMS years ago we used to play disaster landings as a game after work on an faa phase 3 757 in Miami airport. Put the plane 5 miles out heavy mist. Then as they are lining up on descent path put an engine on fire, then give them micro burst (massive downward wind) then maybe a tough crosswind for final landing. We never even thought of automatically making the elevator tri m keep slamming the nose down with the pilot straining at full strength to pull up! That would have just been too silly to believe!

Re: Good news or bad news?

Read the book "Preventing the unthinkable" by James Martin.

Its not some namby pamby pacifist script.

Its full of physics and strategy; probably written for senior civil servants and intended

military staff of rank colonel and above.

A large scale nuclear war is quite complicated. One major physics factor in nuclear war is

most of the initial energy from a nuclear explosion is X-rays. In air these form a large fireball in the sky. In space they fly unimpeded.

Ballistic missiles (those flying in space) are very vulnerable to x-rays from space detonated

atomic weapons i.e. if you keep dropping H bombs above the country you are attacking all the missiles they launch are destroyed in flight. This has a technical term called "X-ray" lock down.

But it does not take care of cruise missiles effectively hiding from the x-rays by being in earths atmosphere.

So thats why anti ballistic missile shields (ABM) can be viewed as first strike weapons. They kind of enable a first strike as well as protecting from the odd stray north Korean missile.

Also Putin, because of ABMs, has simply increased the number of cruise and stealth nuclear delivery systems. my pennies worth. But anyone really interested should read the James Martin book

If you first used vi and are annoyed that vim does not go back into command mode

when you hit a cursor key put this in your .vimrc file.

For poeple who started using vi in the 1980's this makes vim usable.

I used to use a PDP-11/73, and it was multi-user unix, there were about ten people using it most of the time, working on C or with a Z80 cross compiler. vi was in use, a fantastic leap ahead from ed.

It was a gross overreaction though, threatening prison for what really was a university prank involving computers. Anyone with a uni account can download papers, and its common practise to email them to people who you want to read them after that.

It was the criminal justice systems weapons designed for hardened criminals aimed at someone intelectual and sensitive. A criminal criminal justice system IMHO.

Re: This is it!

I am a cyclist and have a resting HB of 45. This means that for the 2 hours or so of cycling to work, I may output a little more CO2, but the obese person is worse, They produce more than me when they are at rest. Nd I bet they use a car too. Tax the unfit!

Re: 3.2 Million reasons to love speed cameras

I have seen someone die trapped in a car in front of my eyes in a road accident.

It was a very upsetting experience.

Not silly talk. 3000 deaths a year on our roads is pretty amazingly high.

Any other `industry' would be shut down. Back to the incident I saw...

The police got there first, I was putting out the fire on the dripping exhaust pipe on the upside down car.

The ambulance and free service were probably lost (I hear they are pretty bad at navigation generally

I guess Rabiit80 if your are really an ambulance driver, you mostly arrive too late)

But I do think, on a lateral tangent here, that technology may well be the only thing to

reduce road deaths. Automatic braking systems to aid the awful human reaction times, and

monitoring via GPS to prevent people speeding (and doing a runner).

All things just around the corner so to speak.

Re: 3.2 Million reasons to love speed cameras

Its mostly third parties that get harmed by speeding car drivers---speed cameras in theUK are placed where someone has died. often a child. Imagine, the child in shock half under the car mangled crying for mummy... but you would rather get from A to B 3 mins quicker....

The driving test should have subtle questions in it to determine if the candidates fully understand

the equation

E = 0.5 * m * v**2.

If they cannot grasp this simple bit of physics they should not be allowed a driving license.
