Secondary Flight Controls Flashcards
What are secondary flight controls used for?
To assist or to modify the effect of the primary flight controls.
Name the components included in secondary flight controls.
- Flaps
- Spoilers
- Slats
- Tabs
What is the primary function of flaps?
To modify lift.
Where are most flaps located on the wing?
On the trailing edge of the wing inboard of the ailerons.
What is the purpose of deploying flaps?
To make the wing more versatile.
Fill in the blank: Flaps Up - Camber; Flaps Down - _______.
[Camber]
List the types of flaps.
- Plain Flaps
- Split Flaps
- Slotted Flaps
- Fowler Flaps
- Triple-Slotted Flaps
- Leading Edge Flaps
- Kruger Flap
What are spoilers used for?
To assist in roll control.
Where are spoilers located in relation to flaps?
Ahead of the flaps.
What are slats and their function?
Aerodynamic surfaces on the leading edge that allow the wing to operate at a higher angle of attack.
How do slats affect an aircraft’s performance?
They allow the aircraft to fly at slower speeds and take off and land in shorter distances.
What are tabs and their purpose?
Small auxiliary devices on primary control surfaces used to produce aerodynamic forces to trim the aircraft.
True or False: Slats increase drag when deployed.
True
What effect do slats have on the coefficient of lift?
They produce a higher coefficient of lift.
What is the function of the Vertical Stabilizer?
Control Yaw
The vertical stabilizer is crucial for maintaining directional stability in flight.
What does the Horizontal Stabilizer control?
Control Pitch
The horizontal stabilizer helps maintain the aircraft’s nose position during flight.
What is the purpose of the Rudder?
Control Yaw
The rudder is used to steer the aircraft left or right.
What is the main function of Wings?
Generate Lift
Wings are essential for keeping the aircraft in the air.
What is the role of the Elevator?
Control Pitch
Elevators allow the pilot to raise or lower the aircraft’s nose.
What do Flaps do?
Change Lift and Drag
Flaps are used during takeoff and landing to enhance lift.
What is the function of a Jet Engine?
Generate Thrust
Jet engines propel the aircraft forward.
What is the purpose of Ailerons?
Rotate Body
Ailerons are used for rolling the aircraft to turn.
What do Spoilers do?
Change Lift and Drag
Spoilers help reduce lift and increase drag for descent.
What is the function of the Cockpit?
Command and Control
The cockpit is where pilots control the aircraft.
What does the Fuselage do?
Carry Payload - Fuel
The fuselage is the main body of the aircraft.
What is the function of Slats?
Change Lift
Slats improve airflow over the wings at high angles of attack.
