I was watching a presentation from a software developers' conference in which the presenter went through the steps leading to the crash of United Airlines Flight 232 to make a point about Crew Resource Management and how it relates to software development.
This prompted me to read the above linked Wikipedia article and see mentions of the flight hours the captain and first officer had accumulated. Now the Wikipedia article on flight hours doesn't explain it, so I was wondering: how are these flight hours logged (and I don't mean on which medium)?
- Are fractions of an hour taken into account or only ever full hours? I.e. if some pilot flew 1:27 h on one flight and 1:33 h on another how does that count towards the logged flight hours?
- Given many regulations surrounding aviation seem to be global, is the way flight hours are logged uniform around the world?
- Any differences between commercial, private and military aviation?
NB: I'm a layperson.
Originally my question also asked for this detail:
- Is the time from the gate to the runway counted?
- In regard to US regulations it's been answered here
