Fundamentals Of Flight

Question 0

What is acceleration?

Answer 0

The rate of change of the speed and/or velocity of matter with time.

Question 1

What are The three types of motion pertaining to flight?

Answer 1

Acceleration, speed and velocity

Question 2

What is speed?

Answer 2

The rate of movement in terms of distance measured in an allotted amount of time.

Question 3

What is velocity?

Answer 3

The quickness or speed of an object in a given time and direction.

Question 4

What is Newton’s first law of motion?

Answer 4

Inertia - an object at rest, or an object in motion will continue in motion at the same speed and in the same direction until acted upon by an outside force.

Question 5

What is Newton’s second law of motion?

Answer 5

Force - change in motion or acceleration, is directly proportional to the amount of force and inversely proportional to the mass of the object being moved.

Question 6

What is Newton’s third law of motion?

Answer 6

Action and reaction - for every action there is an equal and opposite reaction.

Question 7

What is bernoulli’s principle?

Answer 7

When a fluid flowing through a tube reaches a constriction or a narrowing of the tube, the speed of the fluid passing through is increased and its pressure decreased.

Question 8

How is lift accomplished?

Answer 8

By the difference in airflow across the airfoil.

Question 9

What is lift?

Answer 9

The force that acts in an upward direction.

Question 10

What is weight?

Answer 10

The force of gravity acting downward.

Question 11

What is drag?

Answer 11

The force that tends to hold an aircraft back. Caused by disruption of air.

Question 12

What is thrust?

Answer 12

The force developed by the aircraft’s engine. It acts in the forward direction.

Question 13

What is the longitudinal axis and it’s associated autopilot axis and flight control?

Answer 13

Imaginary line down center (nose to tail,) roll, ailerons.

Question 14

What is the lateral axis and it’s associated autopilot axis and flight control?

Answer 14

Imaginary line running parallel to wings, pitch, elevators

Question 15

What is the vertical axis and it’s associated autopilot axis and flight control?

Answer 15

Imaginary line running from top to bottom of aircraft, yaw, rudder

Question 16

What is a flap and its function?

Answer 16

Leading or trailing edge flight surface. Creates extra lift for takeoff and landing by lengthening the top section of the wing.

Question 17

What is the function of a spoiler?

Answer 17

Decreases wing lift by destroying smooth air flow over wing surfaces.

Question 18

What are speed brakes used for?

Answer 18

Used for reducing the speed of the aircraft.

Question 19

Where are slats and what are they used for?

Answer 19

Attached to the leading edge of the wing. When open at low air speeds, they improve lateral control handling characteristics. (Boundary layer control.)

Question 20

What is collective?

Answer 20

When the blades of a helicopter increase the angle of attack or pitch to generate lift.

Question 21

What is angle of attack and how is it measured?

Answer 21

The angle at which the airfoil or fuselage meets the flow of air. Measured in units instead of degrees.

Question 22

What is autorotation?

Answer 22

A method that allows a helicopter to land without using engine power.

Question 23

What are the components of a hydraulic system?

Answer 23

Pump
Actuating unit
Resevoir
Tubing
Selector valve

Question 24

What are some of the main components of landing gear?

Answer 24

Shock strut assembly
Tires
Wheel brake assembly
Retracting and extending mechanisms
Side struts and supports

Question 25

What is the purpose of the shock strut assembly?

Answer 25

It absorbs the shock that would otherwise be sustained by the aircraft.

Question 26

What is the purpose of tires?

Answer 26

Allow the aircraft to roll easily and provide traction during takeoff and landing.

Question 27

What is the purpose of brakes?

Answer 27

To slow and stop. And to prevent rolling while parked.

Question 28

What is the purpose of side struts and supports?

Answer 28

Provide lateral strength/support for landing gear.
