Task G - Operation of System Flashcards
What are the three primary flight controls of the Archer?
Ailerons, Rudder and Stabilator
What type of ailerons does the Archer have?
Differential Ailerons: one aileron is raised a greater distance than the lower aileron which helps with adverse yaw but doesn’t eliminate it!
How do the ailerons work on the Archer?
The upward deflection on the right aileron decreases the camber which decreases lift & the downward deflection of the left aileron increases the camber resulting in increased lift on the left wing.
What axis does the aileron control?
Longitudinal axis
What axis does the rudder control?
Vertical axis
What is the movement called about the vertical axis?
Yaw
True or False: The Archer has an elevator?
False
What is the small tab on the stabilator called?
Anti-servo tab
What is adverse yaw?
The downward deflecting aileron (the one up in the air) produces more lift, and also creates more drag. (thats why we add rudder in the direction we turn) This drag causes the wing to slow down slightly. From the pilot’s perspective the aircraft yaws in the opposite direction of the turn.
What are the secondary control surfaces on the Archer?
Flaps and Trim Tabs
What are the 4 degrees of flap settings?
0, 10, 25 and 40 degrees
What type of flaps does the Archer have?
Slotted Flaps
What is the purpose of slotted flaps?
Produces much greater increases in the maximum coefficient of lift, because of the air pocket in between the flap & the wing.
What is the purpose of the anti-servo tab trim?
It helps decrease the sensitivity of the stabilator which in return helps the pilot from overcontrolling. It relieves control pressure and maintains the stabilator in the desired position.
What does the acronym LHAND stand for?
Lycoming- 180 HP @ 2700, 4 cylinders, 2 spark plugs per cylinder
Horizontally opposed- pistons oppose each other
Air-cooled- not liquid-cooled
Naturally aspirated- no turbo or supercharge
Direct driven- propeller is connected directly to the crankshaft
How is ignition provided to the Archer?
Ignition is provided through each engine-driven magneto, which is separate from the electrical system.
What are the four strokes of the engine?
- Intake: fuel/air mixture is drawn into cylinders (piston starts moving down)
- Compression: used to obtain a much greater power output from the fuel/air mixture once its ignited (piston starts move back upward)
- Power: begins when the fuel/air mixture is ignited, which creates the power that turns the crankshaft (piston goes back down)
- Exhaust: purges the burned gas out of the cylinders (pistons move back up)
What is an easy way to remember what the four strokes of the engine are?
Suck, squeeze, bang, blow
What is the diameter of the propeller?
76 inches
Who is the manufacturer of the propeller?
Sensenich (think of Cessna)
Is the propeller on the Archer a “cruise” or “climb” propeller?
Crusie, fixed pitch
What type of landing gear does the Archer have?
Tricycle Type, fixed
What kind of struts does the Archer have?
Oleo Struts (air/oil)
Which wheel has a “shimmy damper” on it? And what does it do?
Nose wheel. Reduces vibration on the ground & nose wheel straight in flight.
What is the degree of turn on the nose wheel?
20 degrees
Does the Archer use hydraulic fluid or brake fluid for the brakes?
Hydraulic fluid
How many gallons are usable with the tanks full?
48 Gallons
How many fuel pumps does the Archer have?
Two. One electric, one engine driven
What is the fuel flow of the Archer?
- Tanks
- Fuel selector
- Fuel stainer
- Electric fuel pump
- Engine fuel pump
- Carburetor
What is the maximum oil capacity?
8 qts
What is the minimum oil capacity?
2 qts
Where is the hydraulic fluid kept in the Archer?
The left side of the firewall
Describe the electrical system of the Archer
- 28 volt DC system
- 24-volt lead acid battery
- 70 amp alternator
- Constant 28-volt output from the alternator
What are the steps you must take when using the alternate static source?
- you have to shut your window & vents
- Turn on the heat and defrost
- Airspeed will read faster than normal
- Altimeter will read slightly higher
- VSI will show momentarily climb
What does the pitot mast use to relay airspeed?
Ram air
What three instruments are tied to the static port?
Altimeter, VSI, airspeed
Where is the pitot mast located?
Under the left wing
Do the Archer’s backup instruments rely on a vacuum pump or an electrically powered system?
Electrically powered
How does the heat work in the Archer cabin?
Air runs by the exhaust pipes and heats the air
going inside the cabin
Does the Archer have “anti-icing” or “deicing” equipment?
Anti icing
What are the three forms of anti-icing systems?
Defrost, Pitot Heat, Carb Heat
