Ok,

Suppose the plane has just been hi-jacked. You are onboard flight X and it s
going to crash into some building. Would it be possible to take back control
of the flight computer ?

Where is the flight computer located ? AHHHHHHHHHHH

Just curious... in what language would it be programmed... does it have
software or hardware only ?

What about boing 747, 757, 767, 777 ? AHHHHHHHHHHHHHH

I would want as much as information as possible AHHHHHHH.

INPUT PLS, INFORMATION NOWWWWWWWWWWW =D !

Bye,
Skybuck.

We are on to you...Which plane are you planning to skyjack, so that i

may avoid that flight?

Between the pilots' seats typically. On the centre 'console'.

You're a fuckwit.

On the 777 there are two ZX-81s just behind the last overhead compartment.

All modern flight control computers are programmed in INTERCAL. For EMI
resistance, ICs all use Fogal transistor technology.

There is a popular misconception that the Boeing 777 is an airplane.

It's not. It's 1000000 lines of ADA code flying in tight formation.

I'll venture that the flight control computer is in a rack in the
equipment bay under the flight deck, and the display unit is on the
center console. I bet its a VME ARINC power PC, and its all Ada.

Safe, high-integrity subset of Ada, like Spark.

I believe there was some discussion about four years ago on
allowing air traffic controllers to override the onboard computers.

I don't know that anything was ever done, though.

No, it's true. They've been upgraded to 2K and recieve in flight data about
hazards and play 'Pong' between themselves with it.

Every minute the game gets reset with new data.

If one of them wins before the minute is up it activates the voice thing in
the cockpit which says,

Bing and Bong
Bing and Bong
Bing and Bong
Saviours of the universe

Then the pilot and co-pilot get to cuddle themselves a bit more before being
ripped to bits.

Sounds like the ATC guys would want to override the Navigation computer
that flies to a waypoint, not the flight control computer(s) that
update control surfaces to maintain flight.

Here's something that was floating around Boeing a few years ago:

INERTIAL GUIDANCE SYSTEM SIMPLIFIED

The aircraft knows where it is at all times. It knows this
because it knows where it isn't. By subtracting where it is from
where it isn't, or where it isn't from where it is (whichever is
the greater), it obtains a difference, or deviation.

The Inertial Guidance System uses derivations to generate error
signal commands which instruct the aircraft to move from a
position where it is to a position where it isn't, arriving at a
position where it wasn't, or now is. Consequently, the position
where it is, is now the position where it wasn't; thus, it
follows logically that the position where it was is now the position
where it isn't.

In the event that the position where the aircraft now is, is not
the position where it wasn't, the Inertial Guidance System has
acquired a variation. Variations are caused by external factors,
the discussions of which are beyond the scope of this report.

A variation is the difference between where the aircraft is and
where the aircraft wasn't. If the variation is considered to be a
factor of significant magnitude, a correction may be applied by
the use of the autopilot system. However, use of this correction
requires that the aircraft now knows where it was because the
variation has modified some of the information which the aircraft
has, so it is sure where it isn't.

Nevertheless, the aircraft is sure where it isn't (within reason)
and it knows where it was. It now subtracts where it should be from
where it isn't, where it ought to be from where it wasn't
(or vice versa) and integrates the difference with the product
of where in shouldn't be and where it was; thus obtaining the
difference between its deviation and its variation, which is
a variable constant called "error".

Yeah, that's what I thought too. Don't know where it exactly is or if it's
true though.

But let's move on.

Suppose the flight computer is found, is there anything that can be done ?

Maybe cutting some lines to the cockpit... hoping that flight computer will
fall back on auto pilot ???

Bye,
Skybuck.
