Hello,
When I took my first ever lesson in a light aircraft at Manchester back in 2008 (the day MSF closed their doors), I noticed one of the small disposable carbon monoxide detectors stuck to the instrument panel.
Carbon Monoxide Detector - Pack of 5 - Detailed item view - Leading Flight Equipment, Pilot Supplies, Aircraft Equipment, Aviation Headsets
Every lesson I've had since has been with another school, and none of our airplanes have these (or any other) detectors. I've also noticed, from looking around at different schools/FTOs/clubs etc for my future flying, that the use of these detectors is actually quite rare.
I'm just wondering, why is their usage so irregular? How come the use of these is not mandatory in light aircraft if there exists a significant possibility of CO entering the cockpit?
Thanks
Odai.
