In this Design Deep Dive we go flying on the National Flying Laboratory Centre's (NFLC) Saab 340B+ (GNFLB) and we explore some of the interesting design features of this nice little turboprop, from its geometry, payloadrange space, competitors, its CT79B engines, through its OEI (one engine inoperative) design, to its stall warning and stall prevention system, handling, and much else.
