AER4: Practical Application

Question 1

Which control uses longitudinal axis?

Answer 1

Aileron - roll

Question 2

Which control uses lateral axis?

Answer 2

Elevator - Pitch

Question 3

Which control uses normal/vertical axis?

Answer 3

Rudder - Yaw

Question 4

What is stability?

Answer 4

Where such a body is so disturbed, stability is
concerned with the motion of the body after the external force
has been removed.

Question 5

What is static stability?

Answer 5

the immediate

reaction of the body after disturbance

Question 6

What is dynamic stability?

Answer 6

Dynamic

Stability describes the subsequent reaction after a disturbance

Question 7

Positive, neutral, negative?

Answer 7

Positive stability
indicates a return towards the position prior to disturbance,
neutral stability the taking up of a new position of a constant
relationship to the original, whereas negative stability indicates
a continuous divergence from the original state.

Question 8

What aircraft features help aircraft stability?

Answer 8

Control Surfaces - aileron, rudder, elevator
Wing design - dihedral vs anhedral
Wing position - high/low/swept
Centre of gravity position
