About the the size of the cabins in SP familiy
I don't see the logic in reducing the number of seats in the EC225 or the L2 what is the point.
First of all the Operators/ Oil companies would not enterain it would be too expensive to operate a helicopter certified to fly with 19 seats but only fly with 14 it the operating cost's would be suicidle.
Then it would just as easy to operate a fleet of AW139's instead and the cabin size in these sardine cans is even smaller,
With regards to the difference with the S92 and SP familiy I would rather much in an emergency escape from a SP because of the emergency exits you have a large jettison door either side larger escape windows
What do you have in a 92?
The argument is we as human beings are larger then how can you escape from the windows from the 92?
