Regional operations with the Turboprop, prop-jet or Jet
- We examined the future of turboprop airliners Jan. 5, 2015, analyzing the backlogs of Bombardier and ATR–and the ATR overwhelming dominance of the current turboprop sector. This is the second of a series looking at this sector.

Introduction
08 Feb 2015: Passenger traffic is growing the world over on a regional, domestic and international level. For domestic and international airlines the choice of mainline transport aircraft is clear today: there are only two vendors, Boeing and Airbus, and they produce similar products.
For regional transportation there is more choice. First of all, one can chose type
of aircraft, turboprop or jet. Within jet, there are several OEMs that are active. The choice in turboprop is more restricted. In practice, the choice stands between the classical turboprop with ATR and a faster type from Bombardier, the Q400 “Prop-Jet” as it is called, as its speed lands between the classical turboprop and regional jet.
The question is, what are the real differences between them in terms of design, passenger comfort and economics and what is the right choice for a market segment? We will take a deeper look into this by analyzing the ATR72 as the classical turboprop, the Bombardier Q400 as the Prop-Jet and CRJ700 as the regional jet.
Summary:
- The ATR72-600, Bombardier Q400 and CRJ700 are all about the same size, around 70-80 seats single class or 60-70 seats dual class.
- They offer different comfort levels, and it is not all about speed.
- In developing the economics in two steps we seek the crossover points between the different types.

Introduction
25 Jan 2015: Japan has not produced a commercial aircraft since 1973, when the last YS-11 twin engined turboprop rolled off the assembly line. The YS-11 was developed by a consortium of Japanese “heavies,” where two are also active in the creation of the MRJ, Mitsubishi Heavy Industries and Fuji Heavy Industries. This time Mitsubishi Heavy Industries is very much in command as they own 64% of the company set up to develop, assemble and market the aircraft, Mitsubishi Aircraft Corporation, Fuji Heavy Industries are working as design consultants this time.

The first MRJ prototype has run its engines 10 days ago and is preparing for first flight later in the spring. It is therefore time to take a closer look at the first model, MRJ90, and compare it to its direct competitor, Embraer 175 E2.
Summary:
- The MRJ90 and E-Jet 175 E2 are the same size, around 90 seats single class or 80 seats dual class;
- Both aim for scope clause acceptance at 76 seats despite being to heavy; and
- They are different in their fuselage packaging but surprisingly similar in their capabilities.
