Slats there is a big difference between the requirement to carry alternate fuel and the decision to carry alternate fuel. Given point II of your core issues, that decision rests squarely with one person. So the issue of AWK v CHTR is an interesting technical discussion but not really the core issue IMHO. The core issue is how PeLAir supervised and risk managed these flights given the sector lengths. The crew were given limited guidance and assistance to complete the task. The Regulator knew all this and did very little about it, that I think are the two core issues. The performance of the crew after ToD was all their responsibility.
