Operation of Systems Flashcards
1
Q
Primary flight controls
A
- ailerons (differential)
- rudder
- stabilator
2
Q
Secondary Flight Controls
A
- flaps (slotted)
- Trim (anti-servo trim tab)
3
Q
Powerplant
A
- Lycoming IO-360-C1C6
- 200 hp @ 2700 RPM
- 4 cylinder
- direct drive
- horizontally opposed
- air cooled
4
Q
Arrow ignition
A
- provided by 2 engine driven magnetos and 2 spark plugs per cylinder, the battery furnishes electrical power to the starter which rotates the crankshaft actuating the magnetos and provides a spark for ignition
5
Q
What are magnetos?
A
- self-contained sources of electrical power that operate independently of the electrical system
6
Q
Propeller
A
- constant speed made by Hartzell
7
Q
What are the advantages of a constant speed propeller?
A
- allows the pilot to choose the most efficient blade angle for different phases of flight
8
Q
What does the propeller fail to?
A
Low pitch, high rpm
9
Q
How does the constant speed propeller work?
A
- Fly wait inside the governor Since changes in RPM by sensing the change in centrifugal force which then raises or lowers the pilot valve which lets oil in or out of the propeller hub and changes the page of the blade and also changing the RPM
- on speed = flyweight remain in fixed position and no oil is leaving or entering the propeller hub
- over speed (RPM increase) = out, up, in, increases pitch
- under speed (RPM decrease) = in, down, out, decrease pitch
10
Q
How is the landing gear operated?
A
- hydraulically actuated and electrically powered
11
Q
How is the landing gear held up?
A
- held up by hydraulic pressure
- hydraulic pump continues to run until the pressure switch senses 1800 PSI at which point the pump turns off
- if the pressure switch reads below 1500 PSI, the pump is reactivated
12
Q
How is the landing gear held down?
A
- spring assisted down locks and an over entering device
- when the gear selector is moved to the down position, the hydraulic pump reverses the flow of hydraulic fluid allowing the gear to come down
13
Q
Gear warning horn
A
- Gear up with MP below 14”
- Gear selector up with 2 or 3 notches of flaps
- Gear selector up while on the ground
14
Q
What prevents the gear from coming up on the ground?
A
- squat switch over left main landing gear prevents gear retraction while on the ground by disconnecting the circuit and preventing electrical power from reaching the pump
- after liftoff when the strut is fully extended, the circuit closes and allow electrical power to reach the pump
15
Q
Manual extension
A
- Check master on
- Check circuit breakers
- Panel lights off
- NAV light off
- Below 87 knots
- Gear selector down
- Pull emergency gear extension knob
