Chapter 5.4 - Exam Review

Question 1

What is the greatest limiting factor in the design of Aircrafts?

Answer 1

Weight of the structure.

Question 2

Define the term Load Factor?

Answer 2

The ratio of Lift (apparent weight) to the Aircraft’s original weight.

Question 3

Explain the difference between positive and negative Load Factors?

Answer 3

• Positive = Straight and Level Flight and Pull-up Manoeuvres.
• Negative = Lift force acts in the same direction as Weight.

Question 4

What are the three main structural limitations imposed on the operation of a particular Aircraft? How or where do you find what these limitations are for the Aircraft (4)?

Answer 4

• Limiting Structural Weights.
• Limiting Airspeeds.
• Limited Manoeuvres.
• Flight Manual.

Question 5

What does the abbreviation Vne stand for and how do you define it (2)?

Answer 5

• Never Exceed Speed.

- Absolute Maximum Speed for the Aircraft.

Question 6

Define manoeuvre speed and what abbreviation is used for this term (2)?

Answer 6

• Va.

- Lowest speed which limit load can be developed aerodynamically.

Question 7

When should you use the Turbulence Penetration Speed?

Answer 7

When flying into Turbulence with a moderate or greater intensity.

Question 8

Maximum Compartment Load is a structural weight limitation imposed on Aircrafts. Why?

Answer 8

To ensure the Centre of Gravity limits are not exceeded.
