I read somewhere that increased flatulence can cause interference with
airplane equipment. Is it possible that one of your passengers emitted
Flatulence during that period of uncommanded roll?

I think the authors of GASIL do a generally good job in producing
something that is bound to be didactic. But this is one of a few
examples of really awful science. So the autopilot makes an
uncommanded roll and one of the passengers happens to find a mobile
phone on. So the mobile phone must be responsible for the autopilot
issue. Yeah right...

My KAP 140 AP made an uncommanded roll to the right after I invoked it
at cruise a few months ago. No cell phones were on.

An investigation by avionics later discovered that one of the servos
was defective and needed to be replaced.
