If you take safety seriously there is a heads up. Your carbon monoxide detector. Anyone following the rules and taking matters seriously would have one.
So so here are my questions. If the pilot had already demonstrated a lack of recency and a willingness to break the rules, would they have a detector onboard? If they did have a detector would they know what to do when developing a problem at night while IMC and in an area with icing conditions?
Swiss cheese again? One event on its own is a problem. All added together makes for an accident.
