said by Skippy25:It has been shown through many test that no electronic device will interfere with the safe flight of a plane even if used within 3 feet of said equipment. None of us are allowed within 4 to 6 feet any of this equipment while the plane is in flight.
That's not entirely true.
MythBusters did an episode about cell phones and plane instruments. They found phones do not interfere with the newer plane instrumentation, but they included an older VOR receiver in the test and certain phones cause interference in that receiver.
They ended up marking the myth as "plausible" because some aircraft may contain the old equipment.
