Twin Otter Series 400 vs P-750 XSTOL: the key differences
- The P-750 XSTOL delivers 23% more range (Twin Otter Series 400: 920 nm; P-750 XSTOL: 1,130 nm).
- The Twin Otter Series 400 delivers 30% more cruise speed (Twin Otter Series 400: 182 kt; P-750 XSTOL: 140 kt).
- The Twin Otter Series 400 delivers 90% more passenger capacity (Twin Otter Series 400: 19 seats; P-750 XSTOL: 10 seats).
- The Twin Otter Series 400 is the newer design (introduced 2010 versus 2001 for the P-750 XSTOL), a gap of 9 years that usually shows up in avionics, cabin systems and fuel burn.
- The Twin Otter Series 400 is the larger aircraft by maximum takeoff weight (12,500 lbs versus 7,500 lbs), which typically buys more cabin and payload at the cost of higher trip economics.
- The two differ in powerplant layout: the Twin Otter Series 400 runs 2 engines against 1 on the P-750 XSTOL — a factor in redundancy, maintenance scope and operating cost.
Which mission suits which aircraft
The P-750 XSTOL is the stronger fit for regional and short-to-medium legs — its 1,130 nm of range removes fuel stops on those legs. The Twin Otter Series 400, at 920 nm, is better matched to short-haul and regional hops, where lower trip cost counts for more than outright reach. If most of your flying sits inside the Twin Otter Series 400's range, the P-750 XSTOL's extra capability is range you pay to carry but rarely use.
Which should you choose?
Choose the P-750 XSTOL when nonstop range is the deciding factor, and the Twin Otter Series 400 when cabin capacity and payload matter more; the Twin Otter Series 400 holds the cruise-speed edge. The right answer ultimately depends on acquisition cost, maintenance-program status, and what is actually available on the market — talk to our acquisition advisory team to pressure-test the choice against your missions and budget.
