I think you will find that the cost of salaries is one of the most expensive part of any business. In Aviation the biggest expense is fuel and next lies the cost of Pilot wages.
If you remember the 737 had performance problems in its early days. They were eventually sorted out. There is no reason the 195 can't have better lifting devices fitted or engines uprated. Airline requirements can be met if needed.
The guys at Flybe will know very shortly what Aircraft they are getting. In the meantime keep speculating and let the free-moles fly!!
