3. Effects of Controls and Stability Flashcards
What is Pitch?
Pitches around the lateral axis (up and down)
What is Roll?
Rolls around the longitudinal axis (bank left and right)
What is Yaw?
Yaws around the vertical axis (rudder left to right)
What do ailerons do?
Control Roll
What does the Horizontal stabiliser do?
It prevents up and down, or pitching motion of the aircraft nose.
Gives Longitudinal Stability
What do the elevators do?
Control pitch
What does the vertical stabiliser do?
Prevents Yaw
Gives directional stability
What does the rudder do?
Controls yaw
What is a Stabilator?
An all moving tailplane that combines the function of a Stabiliser and Elevator
What are the 3 Axis of Flight?
Roll - Ailerons - Longitudinal
Pitch - Elevators - Lateral
Yaw - Rudder - Vertical
What do all 3 axis’s act through?
The Centre of Gravity
What has replaced pulleys and cable in aircraft controls?
(Large Aircarft)
Fly by Wire
Hydraulics before this
How can aircraft be trimmed?
ELEVATORS - PITCH
RUDDER - YAW
AILERONS - ROLL
What are the 3 types of stability?
A STABLE aircraft tends to return to its original condition.
A NEUTRALLY STABLE aircraft will assume a new position.
An UNSTABLE aircraft will continue to diverge from its original position.
What are Dihedral wings?
Dihedral wings are angled upwards from the fuselage.
They reduce the loss of resultant lift when the aircraft is banking and increase lateral stability.
