Double Bogey & others
Re. the S92 event, yes it is standard practice not to go up with a warning light on, but unless it was something the crew did during pre-flight checks that created/provoked the warning, then it's slightly semantic to say that this was not risk. If the warning light was due to a time-related event, which equally could have happened after take-off, then it definitely was risk in my book. It was only luck that the warning came before take off.
Fully agree about the inflammatory wording "grounded", but then it's what we expect from our Press
