There ARE problems with some devices, but the ipad may not be a problem.
USMC aviators have been using ipads in helicopters for almost two years
(that I know). In same squadrons' aircraft, there have been reports of
interference from other external-use cockpit devices. Marine combat
aviation is a
All,
I happened to have my iPad at work today and ran a scan to 1GHz with a video
playing (didn't bring my charger though). There's a minimum of 20dB margin.
However, the processor runs at 1GHz so I think data above 1GHz would be more
interesting, but my chamber is tied up at the moment.
An interesting situation I ran into; a 10's of kilohertz system with lots of
harmonics that faded fast, got into a 915 MHz radio which then amplified a wide
range of the kHz harmonics to levels notably above the FCC limits.

Are you saying that the problem, for this incident, is with the immunity
part of the standard?

Yes and no. Both devices continued to function correctly. And both passed
emissions. But when near each other, the immune nature one amplified the
emissions of the other. A bit of a surprise for the hf radio guys, they said
something about way out of band... I figure the kHz is modulating the
A couple of years use, of multiple units of a similar model, in multiple
aircraft, by multiple users, in actual operating conditions, makes for a
strong argument of compatibility. Not conclusive, and it doesn't establish
any safety margins, but still a strong argument. Apple owes somebody a
Jar aviators are a sub-species of Naval Aviation - and once off FOB or off
the ship are left to their own devices where the NATOPS is 'optional'. Many
marine aviators have technical degrees, so it is not uncommon for decent
ideas to emanate from the field. It was a jarhead who used his personal
