************************************************************************************** Pilot's Handling Notes for a Savoia Marchetti S.M.81 with Gnome et Rhone GR14K engines ************************************************************************************** The three 650hp Gnome et Rhone (Isotta Fraschini) GR14K engines have automated mixture controls, and manually applied carb heat controls. Superchargers give war emergency power up to 3500 metres and rated power to much higher altitude. This aircraft has two pitch screws operated by the flight engineer whose role is automated within FS9. After climb the screws are locked in course pitch. Each engine can briefly deliver 740hp for TOGA and war emergency use below 3500 metres. WAR EMERGENCY POWER - After take off never exceed 1.0 C2 except in war emergency. NEVER EXCEED 2390 RPM AUTOMIXTURE - This engine has Automixture in real life. Turn automixture ON in the FS9 realism screen before flight. Design cruise altitude is 5000 metres. *************************************************************** Take Off: AUTOMIXTURE = ON (in FS9 realism options) FLAP = STAGE 1 CARB HEAT = COLD TRIM = 10% positive LINE UP BRAKES = ON THROTTLES = FULL BRAKES = OFF YOKE = FULL FORWARD to raise tail TAIL UP - ROTATE FIRMLY RESTRICT CLIMB <= 3 m/s VSI ACCELERATE = 150 KmIAS FLAP = UP ACCELERATE = 190 KmIAS WAIT FOR > 3 m/s VSI Call for Rated power *************************** Rated and Climb power: Plan 1070 PPH C2 = 1.0 190 KmIAS On reaching 5000 metres Call for cruise power *************************** Design Cruise: C2 = 0.9 Plan 860 PPH Note: Yields 174 KTAS at FL164 (5Km) **************************** Econ Cruise: C2 = 0.8 Plan 690 PPH Note: Yields 156 KTAS at FL164 (5Km) **************************** Descent: MAX 310 KmIAS RPM <=2390 OAT <= 5C CARB HEAT = HOT Plan 530 PPH **************************** Approach Circuit and Landing: Before Downwind leg OAT <= 5C CARB HEAT = HOT REDUCE < 200 KmIAS FLAP = STAGE 1 Downwind REDUCE < 175 KmIAS FLAP = STAGE 2 In time to achieve Vref REDUCE < 150 KmIAS FLAP = STAGE 3 CARB HEAT = COLD Vref = Cross airfield boundary @ 110 KmIAS THROTTLES = RETARD (IF REQUIRED) (FLARE) ALWAYS LAND ON MAINWHEELS only WHEN TAIL SETTLES - YOKE FULL AFT FLAP = UP BRAKES - as required ****************************
