Module 4 Stability and Control Flashcards
Roll movement which axis?
Longitudinal Axis
Pitch movement which axis?
Lateral Axis
Yaw movement which axis ?
Vertical Axis
Lateral stability is stable in ?
Roll (longitudinal axis)
Longitudinal stability is stable in?
pitch ( lateral axis )
Directional stability is stable in?
yaw (vertical axis)
Movement around the longitudinal Axis is called ?
Roll
Movement around the vertical axis is called?
Yaw
Movement around the lateral axis is called?
Pitch
Primary Flight control for longitudinal axis movements is called ?
Ailerons
Primary flight control for lateral axis movements is called?
Elevators
Primary flight control for vertical axis Movement is called?
Rudder
Longitudinal movement the stability is provide by ?
Wings
Lateral movements the stability is provide by ?
Horizontal stabilizer
Vertical movements the stability is provide by ?
Vertical stabilizer
The stability about the Longitudinal axis is called
Lateral
The stability about Lateral axis is called
Longitudinal
the stability about the vertical axis is called
Directional
What are the two types of stability
Static stability
Dynamic stability
What is static stability?
Is the initial tendency that the A/C displays after its equilibrium is disrupted
Types of static stability?
Positive, neutral and negative
What is Adverse yaw ?
created during a roll induced turn, increase drag on the outside wing
Ways to control the yaw?
–Aileron/rudder interconnect
–Frise ailerons
–Differential ailerons
–Roll spoiler
What is dutch roll?
Aircraft tends to wander about the roll and the yaw axes at the same time
Types of Canards
Control and Lifting
What is Dynamic stability
Describes the tendency of oscillate after its equilibrium is disrupted
Tail design helps with?
Directional stability = vertical stabilizer and rudder
Stability does not refer to the axis of the aircraft but rather the ?
Behaviour
