**************************************************************************************
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
