Yeah Slezy you are correct, dragging it around a fix @ A050 with the boards out converting fuel to noise will work.
HOWEVER
When you read the contract and you are paid by the hour "Air Time" I'm sure the boss/board/shareholders would much prefer you get an extra 3hr of airtime.
Many things that pilots think are "the right thing to do" are sometimes significantly different to the company line. I worked for a wet lease operator at one stage that had a power by the hour contract, we regularly operated a 757 at M0.68, min cost (fuel) cruise.
Pilots are really good at perpetuating the myth that because they are at the pointy end with the big windows they know what the big picture is. The reality is usually somewhat different.
