737-800 service ceiling?
This is comical, the guy asked a fair dinkum question. Were they really at FL420 or is there another reason for the alt indicated on the IFE and GPS, yet that Q&A gets lost after about 5 replies and now its a pure bitching contest, Go and start a new thread somewhere else and bitch about who has the bigger d!ck and use of GPS down in the cabin
Seems like a pretty good service to me!

For what its worth, this is the latest (and I don't think it has changed recently) policy on GPS's on QANTAS flights. This is from the QF Flight Administration Manual (under Cabin Management):
The use of essential personal medical equipment, electronic watches, cameras,
Global Positioning System (GPS) receivers, pocket calculators and electric
shavers are unrestricted. These devices may be used at any time.
This is further expanded on in a table, classifying these devices as Group 1 PEDs (personal electronic devices) - which classify phase of flight/boarding etc when these devices and the other categories can be used.
It is very clear that Group 1 devices can be used at all stages in the table too.

GPS and camera are in the Group 1 devices, aren't they?
Does it mean that i can use them during take off and landing??
What does Group 2 devices say?

You dont have to worry about that, at about $4M per seat (and there's 10 of them) you could not afford it anyway!

Group 1: Yes at all stages (Boarding, taxi,takeoff, descent, landing, on ground)
Group 2:
Devices permitted for use inflight once the Seat Belt sign is extinguished after takeoff, until top of descent:
PEDs including:
• Personal computers, PDAs, electronic games,
music devices such as AM/FM receivers, Compact
Disk, Mini Disk and MP3 players, and one-way
pagers.
Wireless Local Area Network (WLAN) devices with
in-built WiFi access including:
• Personal computers, PDAs, and computer
peripherals.
Wireless Personal Area Network (WPAN) with
in-built Bluetooth access devices including:
• Personal computers, PDAs, computer peripherals,
headsets, GPS receivers, and cameras
(My underlining in last paragraph - so if the GPS transmits via bluetooth or wireless network then there are some restrictions)
Group 3 and 4 have more restrictions
There is one caveat I have not mentioned: Operational restrictions may be applied by the Captain!

My only question is how on earth you got away with operating GPS inside the aircraft?
In my previous mob, the ladies behind the door would have had your drawn & quartered if they had of caught you, followed by being meet at the gate by your friendly police man.....

Also had them out a couple of times on the friendly jumpseat up the pointy end at Virgin - not a single issue there either.

GPS v's Altimiter
Been interested to read some of the explanations in this thread.
Flying regularly at FL450 the GPS altitude display is normally around 47100 feet, this is on two G530's, both with 50' of each other and also an old Pilot III (just to see what it said)
Is the gap between each pressure level still 30' feet at altitude? Or is it larger as the pressure decreases? If you were at FL450 and had some one exactly below at FL430 would the RAD ALT read 2000 (as an example of measuring the distance between the aircraft using something other than the altimeters) or slightly more?
I've found that the GPS altitude is quite accurate below about FL150 but always over reads the higher you get.

For me, tracking the flight with my humble Garmin 96C GPS is a good way to pass the time. I don't know about others, but I do find it interesting to know where I am, and what towns I'm passing over, even when I'm pax. Some people prefer to read a book, some prefer to sleep, some (geeks, propeller heads) prefer to GPS; we're all different.

FL420 Unpressurised
Am I the only one who noted the post (#4) of Psycho Joe in which he suggests the aircraft was flying unpressurised to get up into a good tailwind? Mate, you have to be joking, surely. Just how many of you are professional aviators, or even aviators?

To Psycho Joe & ZappBrannigan, I trust you were each commenting "tongue in cheek", as VH-XXX obviously was.
You just reminded me of the DJ "for your comfort the cabin will be pressurised" line, which always made me chuckle a little.

As I posted earlier, I find it interesting that the QF website seems to contradict both the crew manual & the airports manual... I guess an email to the manual revisions and/or website department is in order!
I've had people using GPS on board, if in doubt then I just ask that they not use during t/o & landing... I'll have to check but I'm pretty sure on the back of the safety card it says GPS are ok...? Just no Furbys, apparently!

737-800 service ceiling?
I think you are all on the wrong track. If it is a Quaintass 737 it's service tops out at crappy and is usually somewhere between nonexistant to rude. At least it has been in the last 15 years or so.

I doubt you would get a clearance to FL420, anyway. Non-standard non-RVSM level. That's something they suck in trainee controllers with in the sim
Edit: on reflection this seems weird/incorrect since (correct me if I'm wrong) the 320 can't cruise at FL400 anyway - anyway, it's beside the point, it was bumpy at FL400 and they gave us FL410.

I should have written de-pressurised.
