PAXBoy,
I guess that your smokehood is one of those in a cannister which inflates? Can I ask how do you get it through airport security?
I had a big discussion with Manchester Airport security years ago because I tried to carry a life jacket (with CO2 cannister) on-board an Aer Lingus flight. They tried to reassure me that EI actually had their own!!
They just couldnt understand that I needed it in the C150 which I had just flown to England.
Luckily the EI Captain did appreciate that it was needed for single engine overwater flights.
Mutt.
