As a pax on a stop over in Karachi one night, we were told that all cameras etc were prohibited to be used.
Ive also been told to turn off a hand held GPS once
, I questioned her call, but turned it off in front of her. About 5mins later she returned and told me she had asked the captain and he said it was OK for me to leave it on. I had already turned it back on anyway, knowing its purely a Rx device and can not transmit anything.
