Superior performance to the contemporary C90
With 750 SHP PT6A-135 engines (vs. 550 SHP on the E90), the F90 delivers a rate of climb of 2,380 fpm (vs. 1,870 fpm for the E90), cruise speed of 272kt (vs. 248kt) and service ceiling of 31,000ft (vs. 28,100ft). On hot-and-high missions or climbs above 25,000ft to avoid weather, the F90 is clearly superior to the C90/E90, even though both share the same cabin and similar MTOW.
