Which version of the Super Puma is the EC725 made by Helibras based on?
The 225.
Old numbering system was:
1=Civil, 6=Mil
Tonnage category
0 = single engine
5 = twin.
But, had to only be three digits so EC120 no problem but can't have a 6125 or 1125, so:
1+
125
----
225
and
6+
125
----
725
All changed now.....
