Flashcards in PTS Operation of Systems Deck (13)
Primary Flight Controls & Trim
What are the flight controls?
What do they control?
What kind are the ailerons?
How are they operated?
What type of trim
-consists of aileron, rudder, and elevator control surfaces.
-control wheel for ailerons and elevator, rudder/brake pedals for the rudders
- Conventional Ailerons
-operated through cables and mechanical linkage
-Manually operated trim on a vertically mounted trim wheel
Flaps. leading edge devices, and spoilers.
What kind of flaps does C172 have?
What motions do they have?
What positions can they go to?
What is the wing flap circuit protected by?
-extended or retracted
-10,20,FULL (30) positions
-wing flap circuit is protected by a 10-amp circuit breaker labeled FLAP
No leading edge devices on a C172.
Power plant and propeller
What kind of power plant and what does it all mean?
What kind of propeller is it?
What is it made of?
How big is it?
means Lycoming Fuel injected, horizontally opposed 360 cubic inches.
LA 2 is model.
Normally aspirated ( not super/turbocharged)
Direct Drive gearing.
-two bladed, fixed pitch propeller
-one piece aluminum alloy
-76 inches in diameter
Landing Gear & Brakes
-Tubular spring steel main gear shock support
-Single disk, hydraulically actuated braking system. Connected to master cylinder via braking pedals.
Fuel, oil, and hydraulic
Hydraulic fluid is red.
-5 quart minimum
-Max quarts 9
(8 in sump 1 in system)
Components of Electrical System: (9)
Components of Electrical System:
-Standby Battery Switch

ON A BUS SYSTEM
Essential Bus 1 & 2
Avionics Bus 1&2
AHRS is part of this. Accelerometers.
Avionics Bus 1 & 2
Part of the bus system
Pitot-static, vacuum/pressure, and associated instruments
ADC is part of this.
Pitot-static system used a heated total pressure pitot head mounted on the left wing lower surface.
Static pressure ALT source than the outside uses static pressure from the cabin air.
-cabin heat and cabin air control knobs control airflow in cabin.
-air comes from ram air through the air outlets on wings
-heat takes ram air through the air warms from air intake through the motorand through the floor. adjustable defroster outlets also
Deicing & Anti-icing
C172 technically has two of these, the pitot heat and the defrosters.
Fuel Injection System:
Comprised of engine driven fuel pump, fuel/air control unit, fuel manifold, fuel flow indicator, and air-bled type injector nozzles.
Ignition is provided by two magnetos and two spark pulgs in each cylinder.
Total of 2 magnetos and 8 spark plugs in C172.
Ignition is controlled by rotary type magento switch in cock pit with Off L R Both and Start.
