Embraer Unveils Regional Turboprop Concept Something new has been cooking at Embraer for a while and it is a design for a new turboprop that they believe will serve as a replacement in the 50 seat segment. The new aircraft is actually aimed at the 70 to 90 seat segment. A few days ago the Brazilian airframer gave more details on the upcoming new turboprop. One of the most notable aspects to the aircraft that stand out other than the intricate paint work is the aft-mounted engines. Of course while the idea is not new to have engines rear mounted as business jets use this arrangement, it is an odd sighting in use with propellers.
