On the Bombardier website about the Q400, the following information about field performance can be found:
FAR takeoff field length
(SL, ISA, MTOW, HGW) 4,600 ft 1,402 m
Takeoff field length for 500nm sector
(ISA, 70 Pax, IGW) 3,720 ft 1,134 m
Now here comes my question: Could the the Q400 fly a 342nm/633km trip, with a full payload, from an airport with the following data:
RWY length: 3114ft/949m
Field Elevation: 31ft/9m
Temperature: ISA+15°C (which is 30°C)
Maybe this hint helps: a Q300 can do that trip.
Thanks in advance.
