TQ.
You seem to have misread my post because I did not mention suction mounts untill I said about mounting cameras outside. I also did not mention carry-on cameras. I described camera mounting that, in my opinion as the company QM, was a hazard to crew.
FYI I was an A&C Turbine Helis in 1986 followed by piston light aircraft and large turbines and pressurised aircraft before converting to EASA 66 B1.1, B1.2 and B1.4. I have type ratings on B737 and EC145. Your opinions don't really concern me unless you are in my company, in which case I would ask you to visit me for a chat. I was simply giving my experiences and how I dealt with them.
