If the Operator instills the mindset that it is far better, safer, and fully expected for the aircraft to be landed upon reaching the Minimum In-Flight Fuel Level....with no adverse action being taken if that is carried out....then we have a situation where Safety is foremost.
The Debrief following such a precautionary landing should be a two way discussion about the circumstances and reasons that led to the Precautionary Landing with a view towards ensuring future events might be avoided by the involved Pilot(s) understanding what mistakes they made and ways to prevent that from happening again.
One should not have need for many of these debriefs....as if you do then there is some serious problems in "Judgement" by the Pilot(s) running out of fuel.
Fuel Management is a critical skill that deserves very little leeway in performance.
Either you are on top of the situation and are able to effectively manage your fuel and arrive at a proper fueling point....even if a diversion is required....or you fail in your duties as Pilot in Command.
We all make mistakes....but some are "Mortal Sins" that get no forgiveness...running out of fuel while in flight is unforgivable. That is why we have the concept of "Minimum In-Flight Fuel" or "Land Right Now Fuel" as I call it.
