99.99% is 1::10,000. Multiply that by 643 million passengers per year (http://www.transtats.bts.gov/ http://www.transtats.bts.gov/), and you get a lot of interference (64,300 passengers whose devices interfere...).
I believe that the chance of any typical passenger device interfering with critical plane systems is much less that 0.01%, but we need to be careful with seemingly unlikely events multiplied by large numbers.
- enraged_camel 13y ago30% of all airplane passengers never turn off their devices during flights. Now THAT is a large number of devices. How many of them interfered with critical plane systems, and what percentage of that interference caused an accident? This is a situation where we need to move beyond platitudes and run some actual experiments, preferably random controlled trials. Load a couple of planes with several hundred smartphones and tablets each. Have the devices on one plane turned off and the devices on the other turned on. Fly a third plane completely empty as a control group. Measure the interference on all three planes and then compare the numbers.
