Basically if you aren't doing anything to affect the environment around you, you can do what you like with the comp on there. Of course this excludes doing anything like trying to connect to the internet or wirelessly to another device, but you can use the basic programs on the computer.

A sign I saw when travelling said that if you have a laptop with you, airport staff may require you to turn it on, and remove and replace the battery if it's designed to be quickly and easily swapped. Using it on the plane is fine.

PS why not jump inside a plane while its travelling 500mph?
