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.
