A

The Elevator (Pitch) Trim, and the Aileron (Roll) Trim!

17
Q

How do the flaps work in the SR22?

A

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 (:

18
Q

When will the key fob NOT actuate the door locks?

A

When BAT 1 switch is ON

19
Q

The ___ gage is used as the primary source to lean fuel mixture in the SR22

A

TIT (turbine inlet temperature)

  • a sensor in each turbocharger
20
Q

How are the majority of the Engine Indicating System displays received?

A

From a SENSOR that is mounted in the respective area, which MEASURES

21
Q

Starter/Ignition system components and characteristics

A
  • 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
22
Q

What happens to Engine Exhaust after it leaves the cylinders in the SR22?

A
  • 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
23
Q

From the mixture control, fuel is routed to the _________ on the air-induction system throttle body.

A

fuel-metering valve

24
Q

The Engine Fuel Injection system does what?

A

Meters fuel flow in proportion to engine RPM, mixture setting, and throttle angle.

25
Q

Tell me about the Turbochargers in the SR22!

A

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
26
Q

Tell me about the propeller on the SR22?

A
  • 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
27
Q

Increased Oil Pressure acting on the piston in the prop hub will twist the blades towards ____ pitch, ____ RPM.

A

High Pitch

Low RPM

28
Q

During climb and cruise, the governor automatically adjusts prop pitch to maintain a ____ RPM setting

A

2500
