Flight Controls and Axes of Rotation Flashcards
(21 cards)
What are the primary flight controls of an aircraft?
E.
A.
R.
Ailerons, elevator (or stabilator), and rudder
These controls are essential for safe aircraft operation during flight.
What are secondary flight controls and their purpose?
- F
- L
- i
- S
- T
- Flaps – Increase lift and reduce stall speed.
- Leading edge devices – Enhance airflow for better control.
-i
- Spoilers – Reduce lift to help descend or slow down.
- Trim systems – Adjust pitch for stable flight.
Picture a pilot “FLiST-ing” through their pre-flight checklist—it’s quick, efficient, and keeps control smooth in the air! Hope this helps it stick. 🚀
They improve performance characteristics and relieve pilot control forces.
What is the aerodynamic characteristic of turbojet aircraft?
Very clean aerodynamically and land at very high speeds
This affects their flight dynamics and control requirements.
What is the role of spoilers in roll control for turbojet aircraft?
To eliminate adverse yaw
This enhances the aircraft’s maneuverability.
What do spoilers deployed on the top of the wing do?
Disrupt airflow and destroy lift
This can be done automatically or at the command of the pilot in command (PIC).
When are spoilers most effective after landing?
When deployed just after landing
They help destroy lift and improve brake effectiveness.
What is the effectiveness of ground spoilers used just after landing?
More effective at high speed
This is important for managing landing dynamics.
What causes movement about the three axes of rotation in an aircraft?
Control surface inputs
These inputs are critical for maneuvering the aircraft.
What types of stability relate to an aircraft’s axes of rotation?
Longitudinal, lateral, and directional stability
Each type relates to specific axes of rotation.
