We'll i'm new here but this topic was to good to pass up. I fly for an airline and while some of the things said are true, some weren't.
1st. Flight attentdants, well many are very intelligent and nice but then some aren't, nuff' said.
2nd. Usage, each airline is different, so defintely check and if all else fails do what some of you already do, ask the pilots.
3rd. Interference with the a/c, while i've never had a problem with any electronic inteference, i still stress the no electroinc devices below 10,000 feet, (normal for most). but if all else fails ask the pilots.
4th. Altitude with Gps, in my experience with differnt handhelds the altitude will vary greatly sometimes, used to use a G195 in small a/c and was sometimes close but rarely.
5th. Come chat with us, on several occasions i've spoken to people about handhelds vs. the onboard. (which is pretty accurate,great when in the mts. of mexico)
note. The spelling and grammar errors in no way reflect flying abilities.
