Question 14

What are the 2 sub-types of braced type wings? Describe each.

Answer 14

1. Strut braced (Semi-cantilever): Has one or more stiff struts to support the wings.
2. Wire braced: Commonly used in biplanes.

Question 15

Define the empennage.

Answer 15

It consists of the vertical stabilizer (fin) and the horizontal stabilizer.

Question 17

What is a rudder?

Answer 17

It can be used for moving the nose of an aircraft up and down.

Question 18

What is an elevator?

Answer 18

Responsible for the pitching movement of an aircraft.

Question 19

What is a trim tabs?

Answer 19

It aerodynamically minimizes the workload.

Question 20

The principal support of an aircraft when parking, taxiing, taking off, and landing.

Answer 20

Landing gear

Question 21

State the 4 types of landing gear.

Answer 21

1. Tricycle landing gear
2. Conventional landing gear
3. Tandem landing gear
