Movie mistakes

add 100mph extra speed when diving...

Assuming arrow weights 10kg. 100mph from diving, 40 mph from bow = 70m/s
this equals in kinetic energy to 100g bullet at 700m/s (a typical 20mm auto-cannon round at point blank range), but arrow is sharper than a shell. Not surprised that it did go through...

The pandorapedia in the video game (and since they get their infos from the same sources I guess the Activists Guide, too) states that the Na'vi are roughly 3-4 times as strong as humans.
Adding personal experience in archery (and a family-owned business with an amount of plexiglass and other polycarbonate sheets), some simple ballistics/physics (things get faster when they travel downwards) I really would NOT want to be in one of the helicopters being at the wrong end of arrows being shot from a diving ikran... (And shooting at an angle -to proof expected results- was damn difficult! You have a VERY hard time when trying to pierce pc-sheets at an angle.)

The cockpits of all aircrafts on Pandora are designed to keep an overpressure when sealed (the same as-good-as-canon-sources for this info), but the cargo bays are mostly not (the Samson is mainly flying with open or even detached doors and when the shuttle landed we can see the pandoran atmosphere rush into the hold).

Global warming on Pandora... Hmm, interesting but definitely no matter in the movie.

Trudy being charged for disobeying orders:
We see that not all tawtute on Hells Gate are straight on the line with Quaritch -heck, even Parker seems to be thinking about ordering everything off- so it might well be that Trudy created some "engine problems".
With an atmosphere enriched with hydrogen sulfide I wouldn't be too conspicious if maintenance tells me "yeah, 't was much better she return'd, might've cost us another perfect plane oth'rwise". So she get's some "go help them techies fix your plane for the next job" and it's done...
After all: they're mercs hired by a megacorp! And "there's just one thing shareholders hate more than dead indigens: bad numbers!"

When Jake is kneeling at the Tree of Souls "praying' to Eywa his queue is in the wrong place! Before he connects to the tree his queue is going down his back. When he goes to connect it is "magically" going over his shoulder and is in front of him.

I could've sworn in this part you see him grab it and put it near the tree, but I could be wrong. Gotta go see it again...

[Na'rìng]

I noticed a number of mistakes, but thee is one the got me: the air in the helicopter
is the air in Pandora. The same goes true with the air in the cockpit. For humans, that air is deadly. So why do the human pilots not wear masks and not die??? And I've scrutinized what we can see inside the heli and there is no plate of any kind between the cockpit and passenger area, so...

Maybe the filters in the helicopters make breathable oxygen fast enough so the doors can stay open when needed.

The cockpit is segregated from the back cabin, but can be opened to communicate or interact with the people in the back.  The back cabin can be sealed up with side panel doors. There were no transition scenes in the released edit of AVATAR.  But, in the out takes I have seen online, there are some variations on opened or closed cockpits and back compartments being used.

My mom said that she noticed one of the ikran clip through a mountain in the beginning of the battle, can anyone resolve this?

Ikran flew behind the mountain? Just throwing it out there :p

[tute nuereime]

i think he means that the ikran flew into the mountain like a glitch. they had that in the original star wars movies but then again those were a while back and the tech has improved since then.

Maybe mom just saw it wrong?

Perhaps, just wondering if anyone could confirm it.

There were a ton of Ikran in that fight... 
Which Ikran? 
Time signature?   
Physical location on the screen?

LOL!
I haven't taken the time to watch every single ikran and at the moment I can't remember any of them doing such a bad thing as glitching (you get banned from server for that,you know?!)... err... well, poor me will have to go see the movie another time to make sure...
Even if: it would be the first mistake we find and can confirm.

[Tìng Eywatikìte'e]

I'm going again tomorrow! I'll be on the look out!

[Txontaw]

Cool, thanks. It would probably be more in the background.

[kintìomum]

Now, after fighting back the initial "Whoooho! Go for it!" I looked for the glitching ikran and...
found none. Might well be I just didn't see it, there are so many.

But I think I found at least a logical mistake:
OK, bit more of a wide swing of story and background necessary:
Avatars are damn expensive (I remember hearing about 5 million per piece).
The Avatars are "set up" on Earth in the High-Tech-Labs of the RDA.
An Avatar has to have DNA of his future operator spliced into it to enable the link.
- So far this is deduction off the movie or questionable resources (the video game), or off the ASG
During the flight to Pandora they grow to full size/functionality.
- Max and Norm talk about this when Jake first enters the Biolab and the ASG states this, too
Sooo, when Norm and Jake enter the LinkLab the next morning Grace asks how much linktime they both had. And here's the point: Norm states he's got "about 520 hours".
How? Is the Avatar he's going to use on Pandora his second? Did he link to the "baby avatar" while it was floating in the tank?
If the Avatars are only growing to functionality during the flight and Norm was in cryo during that flight I don't see a way how he could get that much experience...

[Txura Tirea]

Hm, maybe they created human bodies on Earth to pratice with. Wow, that sounds so wrong. 

[Na'rìghawnu]

Norm states he's got "about 520 hours".
How? Is the Avatar he's going to use on Pandora his second?

Could very well be the fact. Or he had his practice with a computersimulation or so.
When they connect the first time on Pandora and awake their avatars, Norm is doing this "thumb to finger" exercise. And as he does so, one of the assistants says something like "Very well, you do remember, don't you". (Don't know the exact phrase, because I saw the german synchro.) But this also suggests, that Norm was in an avatar-body (maybe a simulated one) before.

[MaTe]

Hm, maybe they created human bodies on Earth to pratice with. Wow, that sounds so wrong. 

seems perfectly reasonable. IIRC Earth can't transplant personality as Eywa did, but that's the default way to get around aging in mainstream sci-fi.

[Le'tutean]

at the start of the movie, when Jake and Norm first meet, he said he was on avatar training with Tommy, and later Grace reveals it took 3 (or was it 5??) years. Who knows what kind of training it was, but i guess they didn't just read on how wonderful tech is behind all this. So some sort of simulation with use of Links is quite possible.

And one thing about the cost of each avatar.
I don't remember hearing anything about it, other then it's very expensive. But keep in mind that everything on Pandora is ridiculously expensive, since most of the stuff is shipped from earth, and shipping one pound of freight costs around 1.000.000 $ (so shipping one person, one way, would take around 200mil or so). And if a person is a driver, then i pretty much doubles (driver + his avatar). And im not even counting in any food/water or other supplies. Geezzz, one hell of an expensive ride
