Ever thought about a BK 117?
Yes we have, but I will consider it more seriously reading your positive feedback
When comparing 109 E & S you will be surprised to see that S burns less fuel for same speed!
Very glad to hear that. Will take it into account. The S takes 175Kg more than the Power but..... will its empty weight be higher as to maintain the same pay load?
This is a VERY simplistic look at the numbers
Good enough for a start. We all know that it will always be more than we think. When we begin to weight "all stuff on board" the numbers will never go below expected so 499Kg will be more likely 300+ with the "forgot to mention things" and that takes me to the same place our client wants us out of.
How much fuel would really be needed for your calculations to satisfy the authorities?
That is the key most of the times. A helicopter is not an airplane, we can not use the whole tank for the reserve, plus extra, plus 10%, plus, plus, etc
. It would not be possible then to make an IFR leg
