Other mistake: While flying the helicopters, notice that the human pilots are not wearing protective masks in an open cockpit with the cargo doors wide open as the Avatars are either hanging out of, or staining to see past the pilots.
Suggested correction: This has been submitted and corrected three separate times. The cockpit is sealed off from the outside.
Baloney. The movie made several egregious errors involving the use of masks. In several scenes you see them not wearing masks in human form including going into the lab at the floating mountains. Everyone including Trudy should have been dead within minutes.
Other mistake: In the scene after Jake first links to his Avatar body and they are getting ready to put the Avatar's to rest, Grace gets the human scientists to 'scat' and shuts two large gates behind them. There is a CGI error with Grace's left hand. Her hand is not holding the gate handle but is pulling it shut anyway.
Other mistake: When Michelle Rodriguez is flying the copter she doesn't have a mask on when they are at the tree of life to shoot down the tree. The machine gunner has his mask on. It's an open cockpit.
Other mistake: During the battle between the marines and the Navi, colonel Quaritch shoots down Trudy's ship. Despite her cockpit having bullet holes in it, somehow she is still able to breathe. Unlike Quaritch when Jake sticks the knife into his AMP.
