Airplane basics

Question 1

What change the Wing’s Configuration?

Answer 1

**Flaps:** Change the Wing’s Configuration
 Affects Lift (and Drag) for Takeoff / Landing

Question 2

What are the aircrafts basic parts?

Answer 2

• Empennage
• wings
• fuselage
• powerplant
• landing gear

Question 2

What components make up the empennage?

Answer 2

• Vertical stabilizer
• Rudder
• Horizontal stabilizer
• Elevator

Question 3

Where are disc brakes located?

Answer 3

Disc brakes are located on main wheels, not on the nosewheel.

Question 3

If you push on the right rudder which way does the rudder deflect? What happens to the tail and what happens to the nose?

Answer 3

The rudder deflects right which pushes the tail to the left and the nose to the right

Question 4

How are brakes activated?

Answer 4

Hydraulically actuated by pressing the tops of the rudder pedals.

Question 4

Pulling back on the control column deflects the elevator which way. An what does it do to the nose and tail? Think of what the relative wind is doing. to the control surface

Answer 4

Pulling back on the control column deflects the elevator up which pushes the tail down and the nose up

Question 5

What is differential braking?

Answer 5

This means that the left or right brake can be applied individually, which enables the aircraft to turn about on its axis

Differential braking may be used to help steer the airplane while taxiing, but only when absolutely necessary.

Question 5

If you turn the control column to the left, the left aileron is …

Answer 5

If you turn the control column to the left, the left aileron is deflected up and the right Flaps extend from wing root to the midpoint.Lift altering devices used for takeoff and landing.aileron is deflected down

Question 6

What is the difference between braking steering and no brake steering

Answer 6

Most commercially manufactered airplanes, including the 172 have a non-castoring nosewheel. These airplanes are steered with the rudder pedals.

Bill thinks the reason why you wouldn’t want to steer a non-castoring with the brakes is because of excessive stress in the nosewheel

Lancair has a castoring nosewheel and is steered with the brakes

Question 6

Where are the flaps?

Answer 6

Flaps extend from wing root to the midpoint.Lift altering devices used for takeoff and landing.Flaps extend from wing root to the midpoint.Lift altering devices used for takeoff and landing.

Question 7

Differential braking may be used to help steer the airplane while taxiing, but only when absolutely necessary.

Why only when absolutely necessary?

Answer 7

Not sure of the answer. Hoping Bill can help.

Question 7

What are the flaps?

Answer 7

Lift altering devices used for takeoff and landing

Question 8

What are the four phases happening in a turbine engine?

Answer 8

• intake
• compression
• combustion
• exhaust

Question 8

Where are ailerons and what do they control?

Answer 8

Ailerons: on Outer End of the Wing , Directional Control via Roll / Bank

Question 9

With Tri-cycle landing gear were is the third wheel?

Answer 9

Tri-cycle Gear: The third gear is under the nose of the airplane

Question 10

Conventional landing gear is referred to as a

Answer 10

Conventional landing gear is referred to as a tailwheel configuration

Question 11

Wheels are usually attached to the fuselage by ? And What do they do?

Answer 11

Wheels are usually attached to the fuselage by struts that absorb shock of landing, and the load of taxi and takeoff

Question 12

What are the axis of flight? And what motion do they control?

Answer 12

Lateral Axis = Pitch Vertical Axis =Yaw, Longitudinal Axis = Roll

Question 13

Air density ?? as altitude increases

Answer 13

Air density decreases as altitude increasesAir density decreases as altitude increasesAir density decreases as altitude increasesAir density decreases as altitude increasesAir density decreases as altitude increases

Question 14

As a balloon rises what happens to the density and pressure of the air around it? What happens to the buoyant force ?

Answer 14

But as it rises, the density and pressure of the air around it decrease so the buoyant force decreases too

Question 15

When the balloon reaches a height where the buoyant force equals the balloon’s weight what happens?

Answer 15

When the balloon reaches a height where the buoyant force equals the balloon’s weight, it stops rising.

Question 16

For buoyancy to push something up in the air, the thing has to be ?? than the air around it.

Answer 16

For buoyancy to push something up in the air, the thing has to be lighter than the air around it.

Question 17

What is Archimedes Principle?

Answer 17

Any object, wholly or partially immersed in a fluid , is buoyed up by a force equal to the weight of the fluid displaced by the object

Question 18

What is Bernoulli’s Principle?

Answer 18

• When airflow area is constricted, velocity increases and static pressure decreases

Restated, the air has to speed up to get the same amount of air through a smaller area.

Question 19

What are the forces of flight?
