A good point Rotorspeed. Sadly, in some ways, the OEMs are like the operators. always thinking that more is better because that's the conventional thinking.
But, the helicopter travelling workforce has had enough and the message is getting through to the oil companies very quickly. The travelling workforce want more room and less clutter. Improved comfort will be a welcome by product. Those companies which don't listen will find themselves without a willing workforce.
Even EC / Airbus is now beginning to realise (probably trying to avoid future liability claims) by pushing a better seating plan to the oil companies and operators. The operators are not selling it to the oil companies because they have no leadership, they still think more is better.
Cramming 19 passengers into the woeful cabin of the EC225 will soon be a thing of the past. You can agree or disagree but lower passenger numbers are coming to EC225s and S-92s soon. The 175 and 189 may also be re configured, both Airbus H and AW are talking to those who pay the bills.
