VF: Maybe it's just a question of nomenclature. The old Jetranger has "chin" bubbles at the nose and feet of the pilot. The "new" Jetranger does not, as you mentioned.
However, the AS-350 doesn't have proper chin bubbles either. It does have "cheek" bubbles, which afford visibility downward and to the side. Similarly, the new Jetranger has a wide, floor level windscreen which should afford similar visibility as the AS-350.
Just curious as to why the new Jetranger couldn't provide the same level of utility ops visibility as the venerable Squirrel.
