What makes a good regional jet?

[chornedsnorkack]

In October 2001, Embraer 170 was rolled out. Eventually it flew, entered service, and lots of 170, 175, 190 and 195 planes are in service now.
In March 2002, Dornier 728 was rolled out.
Embraer 170 and Dornier 728 are similar in having a low wing in the span range of 26...29 m, twin underwing engines, target take-off weights of 35...40 tons, versions for 70...80 and 90...100 passengers.
One difference is fuselage width - cabin width 274 cm for 170 and 325 cm for 728.
Dornier 728 had 125 firm orders, including customers like Lufthansa.
And Dornier 728 has not flown to date.
Why did 170 succeed and 728 fail?

Could be down to many many issues

Initial Buying Price
Cost of running it
Experience with either Embraer or Dornier

To name a few

Why did 170 succeed and 728 fail?

Probably something to do with Dornier does not exist. Dornier went bust in 2002 and was bought by Fairchild. Fairchild then sold Dornier to an American investment company who then spilt it in two to cover the Airbus parts production that Dornier had and another to cover parts and maintenance of Dornier aircraft.

Price, customer support, competitors.

Embraer has always been cheaper compared to the rest.

Dornier had the problem of trying to get into the Fokkr dominated European RJ market... in the 2000s that was near impossible
Probable reasons:
[*]Fokker airframe life expectancy is way more than that of the competition
[*]Fokker is the widest RJ around (built before the real RJ craze, its more like a small airliner)

In the 2000s, there has been no Fokker. Nor has Rekkof produced any Fokkers.

From what I remember, Fokker is the narrowest classical 5 abreast twin. Cabin width is said to be 313 cm for DC-9/MD-80/MD-90/B-717/ARJ-21 family, 316 cm for BAC/Rombac 1-11 and 310 cm for F-28/100/70 family. Dornier 728 is definitely slightly wider, with 325 cm cabin width.

but still wider than a junglejet (E134/140/145) or crj
