Airplane basics Flashcards
What change the Wing’s Configuration?
**Flaps:** Change the Wing’s Configuration Affects Lift (and Drag) for Takeoff / Landing
What are the aircrafts basic parts?
- Empennage
- wings
- fuselage
- powerplant
- landing gear
What components make up the empennage?
- Vertical stabilizer
- Rudder
- Horizontal stabilizer
- Elevator
Where are disc brakes located?
Disc brakes are located on main wheels, not on the nosewheel.
If you push on the right rudder which way does the rudder deflect? What happens to the tail and what happens to the nose?
The rudder deflects right which pushes the tail to the left and the nose to the right
How are brakes activated?
Hydraulically actuated by pressing the tops of the rudder pedals.
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
Pulling back on the control column deflects the elevator up which pushes the tail down and the nose up
What is differential braking?
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.
If you turn the control column to the left, the left aileron is …
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
What is the difference between braking steering and no brake steering
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
Where are the flaps?
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.
Differential braking may be used to help steer the airplane while taxiing, but only when absolutely necessary.
Why only when absolutely necessary?
Not sure of the answer. Hoping Bill can help.
What are the flaps?
Lift altering devices used for takeoff and landing
What are the four phases happening in a turbine engine?
- intake
- compression
- combustion
- exhaust
Where are ailerons and what do they control?
Ailerons: on Outer End of the Wing , Directional Control via Roll / Bank
With Tri-cycle landing gear were is the third wheel?
Tri-cycle Gear: The third gear is under the nose of the airplane
Conventional landing gear is referred to as a
Conventional landing gear is referred to as a tailwheel configuration
Wheels are usually attached to the fuselage by ? And What do they do?
Wheels are usually attached to the fuselage by struts that absorb shock of landing, and the load of taxi and takeoff
What are the axis of flight? And what motion do they control?
Lateral Axis = Pitch Vertical Axis =Yaw, Longitudinal Axis = Roll
Air density ?? as altitude increases
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
As a balloon rises what happens to the density and pressure of the air around it? What happens to the buoyant force ?
But as it rises, the density and pressure of the air around it decrease so the buoyant force decreases too
When the balloon reaches a height where the buoyant force equals the balloon’s weight what happens?
When the balloon reaches a height where the buoyant force equals the balloon’s weight, it stops rising.
For buoyancy to push something up in the air, the thing has to be ?? than the air around it.
For buoyancy to push something up in the air, the thing has to be lighter than the air around it.
