Can I use my Digital Camera on an aircraft?Are there any security regulations?

NO problem whatsoever! really I did on a dehli-frakfurt flight 2 months ago!!!!!!!!

On an Air Jamaica flight from Miami to Jamaica, passengers were instructed not to take photos when we flew over Cuba.

Having flown from Long Beach to Boston, I used my digital camera and took some wonderful photos of the Grand Canyon at 30,000 feet without any problems. You might just want to wait until the aircraft is airborne before using as it might cause interference with the craft's electronics.

Yes you can use it, the cameras doesn't affect the navigation systems of the aircraft's. You can use digital cameras, and video cameras
