All that is a paperwork exercise conducted before even getting into a helicopter-and therefor useless when actually flying...
The question was about a check when flying......
And the deal is:
Will I have enough power available with the fuel/load, temperature, altitude and space available I have NOW, and will I be able to take-off again?
There is no chart for that (unless in the military, flying with a crew of 3, 4 or more, where one has enough time and staff on hand to read through all that crap while doing your recce).
The majority of us Utility pilots fly single pilot, and have to fly in rough terrain.
That's where our "rules of thumb" come in handy...
