Is this true? The last Airbus I was in had a LINUX based entertainment

Why should they mix operating systems?


Why not? The cabin enviornmental controls are designed for Airbus,
the entertainment systems are purchased by the airlines.

The other day as I was boarding a new A320 I noticed the first officer
was typing on a laptop that was mounted in front of him (of course the
Airbus has no yoke so there is more room).

I hate to say it but Windows controls the cabin functions (heat/ac,

Here's the scenerio I see already.

My niece (The little spyware magnet) is surfing the net on the 777's
In Flight Entertainment system. She downloads a trojan that requires
the Captain to "Punch the Monkey" every 60 seconds so he can see the
ILS approach display.


Oh, the horror.....

Windows CE is old. I run Windows SE in my cockpit.

Windows NT made it onboard a Navy guided missile cruiser with these
results:

The US Navy's so-call "Smart Ship technology" left the Aegis missile
cruiser USS Yorktown dead in the water off the coast of Cape Charles,
Va. for several hours. The shutdown of the ship's propulsion was
credited to a database overflow in a Windows NT system. The crash was
caused by the inability of the OS to properly handle division by
zero. Said Anthony DiGiorgio, a civilian engineer with the Atlantic
Fleet Technical Support Center, "Using Windows NT, which is known to
have some failure modes, on a warship is similar to hoping that luck
will be in our favor." The Navy is still expected to spend $138
million expanding the "Smart Ship" program to the entire Aegis class,
and to other ships in the fleet. (Government Computer News, 13 July
1998)

Hi,

I was flying (on American) from LAX to SJC today on an EMR 140 RJ.
We get pushed back. After about 5 minutes, the captain says: "We
need to reboot the computer. The emergency lights will come on for
about a minute. This happens all the time. It's perfectly normal."
He rebooted, fired up the engines, and off we went.

I had no idea that a pre-taxi step was "Computer: REBOOT".

Many airliners use FMS (Flight Management System) and no movement is allowed
while the system is "initializing". They might not have noticed that
wasn't complete before starting their pushback. It would be necessary to
"reboot". Perhaps his "stable table" for IRS use is an AHARS unit. On that
type system there are no switches to "reboot" it if it has a problem. You
have to remove normal aircraft electrical power and bring the power back on
line one side at a time within a specific time period. This starts a new
"initialization" of the gyro system. On the MD80 aircraft the captain could
have used the Ground Service power system to keep the cabin lighted with
normal power while he turned the generators off and then back on. Either
the EMR 140 RJ doesn't have that capability or the captain forgot.

Thanks! Very interesting.

I thought it was the IRU or INS that required no movement? If the
position is fed to the FMS from a GPS receiver there's no problem with
movement per-se, it just takes a little longer to finish acquisition.

And it usually would be difficult not to notice the system hadn't
finished aligning - are these things part-glass? I don't know of a
glass system that doesn't X or blank out at least the AI and nav
display whenever the system doesn't have alignment. Don't they also
have a caution "IRU x ALIGN" message on the EICAS?

I was on an CRJ-700 and experienced the same thing a few weeks ago,
also at LAX. Kinda disconcerting.

Regarding the poster that begged that Windows CE never make it into the
cockpit... too late! I believe some Horizon/Alaska flights use an
iPaq of some sort to do weight & balance, and maybe others do too.
