So let's get started.

Wendon

WJ-PR: This plane is the smallest one Wendon makes. Built for the reigonal turboprop market, it is the most agile in it's class. Might want to an eye on the fuel gauge, though

WJ-4 MDZ: This is the most popular plane made by Wendon. It boasts a pair fuel efficient Blasto XF-160 R engines and a unique streamiled design.

WJ-12 MDZ: Originally meant to be a replacement to the failed WJ-6, it was deemed too small so it sits in between the WJ-4 MDZ and a bigger plane

WJ-8: This is the actual successor to the WJ-6. It boasts a pair of state of the art Blasto EF-180 engines, a ultramodern cockpit and in flight entertainment.

BLK

170 NWA: It's the smallest plane BLK makes and it's closest competitor is the WJ-PR. It has advanced specially made engines and flight systems.

570 NWA: In a highly crowded segment, this plane is on top. The special T-tail allows more cabin space and more passengers, which equals more profit.

670: Despite the 570 NWA being the most popular plane in it's class, it can't compete with the popularity of the 670.

770 NWA: It's the biggest plane in it's class and currently, the only new plane in it's class.

Duroranc

SBF-2: it competes with the Wendon WJ-12 MDZ, the Wendon WJ-8 and the BLK 670. How? Model range of course! Duroranc market the SBF-2 mainly on it's range versitility.

TBP-4 N3W: It sells well because it's the only plane in the short haul turboprop segment.

Proxima

PXR: It's a hit among airlines and competes with the most popular airliners from Wendon, BLK and Duroranc. It's also more efficient, too.
