ATRs would require a bit more runway, wouldn't they, so I can't see them completely migrating.
Or maybe I have the wrong impression of a lot of the airports they'd be flying into out west. Happy to be corrected, as it would save me the cost of an airfare to see for myself
Not much difference, the SAABs are not great performers when it comes to runway length, they require 25% more balanced field length compared to most medium size turboprops which puts them closer to the bigger ATRs
SAAB 340b at MTOW in ISA needs 1285m TORA
ATR72-600 at max PAX and a 300nm leg needs 1175m TORA under ISA conditions
