Could we please keep the PPL/General Aviation stuff in another forum where it belongs?
I posted a set of comments, not long ago, on what I believe I’m seeing more regularly in this industry … that being the development of, and the subsequent dependence on, a “set of numbers” that are presumed to be the “answer” to the problem or the situation under scrutiny.
It's been like this for 50 years or more, when flying high performance jet aircrafts. You ever heard about
:
Flying by the numbers.
You don't go around guessing in a aircraft that e.g. has a TOW varying between 45000 and 77000 kg weight, depending on the task of the day. For a very good reason, we rely on either calculated values or set number to accomplish certain tasks. Your rant was appropriate in the previous thread about sidestep. But here it has absolutely no value, and unfortunately devaluates your position, as your post show lack of knowledge in airliner operation.
