100LL (blue)
100 (gree)
What temperature Range are we looking for with CHT?

What in.Hg range are we looking for with Manifold Pressure?
Green Arc
15.0” - 36.5’”
What range PSI are we looking for with Oil Pressure?
Green Arc
30 - 60psi
Oil TEMPERATURE should never exceed:
240 deg F
What oil temp/psi indicated the engine has been properly warmed?
100 deg F (38 deg C)
PSI does not exceed 70 when running up at 2500rpm
What Range are we looking for with the Turbocharger Inlet Temperature? (TIT)
Green Arc
1000 - 1750 deg F
What Volts range do we want with:
- Essential BUS
- Main BUS 1
- Main BUS 2
24.5 - 32V
BATT 1 Current may be discharging up to __ and still be in Normal Range
- 4 Volts
Because of the aircraft’s turbocharged system, ___” Hg manifold pressure are maintained for ALL takeoffs
36.0” Hg
What effect will utilizing the Alternate Static Air have on the instrument indications?!
They will read HIGHER than what is true
Which electronic trim systems operate on 28 VDC, supplied through a 2-amp (unique) TRIM circuit breaker, on the ESS BUS 2?
The Elevator (Pitch) Trim, and the Aileron (Roll) Trim!
Which electronic trim system(s) operate on 28V DC, supplied through a 2-amp (unique) TRIM circuit breaker, on the ESS BUS 2?
The Elevator (Pitch) Trim, and the Aileron (Roll) Trim!
How do the flaps work in the SR22?
Powered by a 28V DC through 10-amp FLAPS circuit breaker on NON ESS BUSS
Electrically controlled through a motorized linear actuator that is mechanically connected to both flaps by a torque tube (:
When will the key fob NOT actuate the door locks?
When BAT 1 switch is ON
The ___ gage is used as the primary source to lean fuel mixture in the SR22
TIT (turbine inlet temperature)
- a sensor in each turbocharger
How are the majority of the Engine Indicating System displays received?
From a SENSOR that is mounted in the respective area, which MEASURES
Starter/Ignition system components and characteristics
- 28V DC supplied through 2-amp STARTER circuit breaker on NON-ESS BUS
- 2 engine-driven mags
- 2 spark plugs in each cylinder
- OFF positions = starter electrically isolated
- Turning BAT MASTER switch ON will allow mags to energize when ignition is turned to START
What happens to Engine Exhaust after it leaves the cylinders in the SR22?
- Exhaust gases flow through the Exhaust Collector to the turbocharger Turbine Inlet, providing turbine wheel rotation!
- Then it exits through the turbine housing discharge port/tailpipes of lower cowling
From the mixture control, fuel is routed to the _________ on the air-induction system throttle body.
fuel-metering valve
The Engine Fuel Injection system does what?
Meters fuel flow in proportion to engine RPM, mixture setting, and throttle angle.
Tell me about the Turbochargers in the SR22!
Twin turbos
- Use exhaust gas flow to boost induction air pressure for increased power
- Turbos compress and raise temp of incoming air BEFORE going to the intercoolers
- There is 1 wastegate that controls the amount of exhaust gas is used by the turbochargers
Tell me about the propeller on the SR22?
- Composite, 3 blade, constant speed, governor regulated prop
- Prop governor automatically adjust prop pitch to regulate RPM by sending engine oil to the governing pump, to/from a piston in the prop hub, and then centrifugal force and a spring twist the blades
Increased Oil Pressure acting on the piston in the prop hub will twist the blades towards ____ pitch, ____ RPM.
High Pitch
Low RPM
During climb and cruise, the governor automatically adjusts prop pitch to maintain a ____ RPM setting
2500
