Breda Ba65 with Fiat A.80RC41 engine handling notes
***************************************************
The 1000hp Fiat A.80 RC41 engine drives a licence built Hamilton Standard constant speed airscrew. This engine has automatic mixture control and manually applied carb heat controls. The supercharger maximises rated power at 4100 metres. Design cruising altitude of the engine is 5500 metres, but Ba 65 design cruise altitude is only 4500 metres.
MAXIMUM RPM may be employed ONLY for TOGA and WEP........DO NOT EXCEED 2000 RPM in normal flight.
SUBJECT TO THIS RESTRICTION full throttle may be employed continuously at any altitude. The manifold pressure gauges of this aircraft are calibrated in Kg/Cm^2 abbreviated C. The A.80 engine is auto boost limited to 1.0 C which is less than 1.0 Ata = zero PSI boost.
Maximum and default fuel load is 460Kg (1,014lbs) of low lead 87 Octane AVGAS.
Use parallax compliance to achieve IP
Cross IP = 220 KmIAS
Turn = 45 degrees to attack vector
Height = 1000M QFE throughout
After 30 seconds
THROTTLE = CLOSED
>>>>>>>>>>>>>>>>>>>>>>>>>>
DIVE = PITCH BAR TO ROLL CUE (-35 pitch)
HUD = achieve target parallax compliance
SLIP BALL = CENTRE
ROLL CUE = CENTRE
KmIAS > 400
*DO NOT EXCEED 450 KmIAS*

BOMBS = RELEASE (P key)
WHILE paused review fire control compliance
Unpause (P key) then (/ key) to remove bomb drag

Before Joining Circuit - Arrival phase:
@ Vref = 160 KmIAS
C < 0.5 allowed (but high sink rate)
LAND on MAINWHEELS
*********************
After landing phase:
CORRECT DRIFT
PLACE TAILWHEEL ON RUNWAY
STICK FULL AFT
RPM > 1000 (for 'adequate' steering)
PARKING BRAKE = (cadence as required
FLAP = UP (causes slats to close)
COWL = 100% OPEN

PARKING BRAKE = ON
RPM LEVER = MAX
RPM = 1500 (tight static turn)
BRAKE = OFF
RPM = 1800
Once Rolling
RPM <> 1300 for steering on grass
PARKING BRAKE as required
