Stability & Effects of Control Flashcards
What is the longitudinal axis of the aircraft?
The axis from nose to tail.
What is the lateral axis of the aircraft?
The axis from wing to wing.
What is the Vertical axis?
The axis from top to bottom.
How does the aircraft move around the longitudinal axis?
The aircraft uses ailerons to roll around the longitudinal axis
How does the aircraft move around the lateral axis?
The aircraft uses elevators to pitch around the lateral axis.
How does the aircraft move around the Vertical axis?
The aircraft uses rudder to yaws around the vertical axis.
What is the secondary effect of roll?
Yaw
What is the secondary effect of yaw?
Roll
When subject to a deviation, what will a stable aircraft do?
A stable aircraft tends to return to its original position.
When subject to a deviation, what will a neutrally stable aircraft do?
A neutrally stable aircraft will assume a new position.
When subject to a deviation, which will an unstable aircraft do?
An unstable aircraft will continue to diverge from its original position.
What is lateral stability?
Stability in Roll
What is longitudinal stability?
Stability in Pitch
What is directional stability?
Stability in Yaw.
Describe Dihedral
When wings are angled upwards from the fuselage.
