Block XIV- Fundamentals Of Flight

Question 1

What is acceleration

Answer 1

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

Question 2

What is speed

Answer 2

The rate of movement in terms of distance measures in an allotted amount of time

Question 3

What is velocity

Answer 3

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

Question 4

What is Newton’s first law

Answer 4

(Inertia) an object at rest will stay at rest or an object in motion will stay in motion at the same speed.

Question 5

What’s Newton’s second law

Answer 5

(Force) the change of motion 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

Answer 6

(Action and reaction) every action there is an equal and opposite reaction

Question 7

What is Bernoulli’s principle

Answer 7

When fluid flowing through a tube reaches a constriction the speed of the fluid passing through is increased as pressure is decreased.

Question 8

How is lift accomplished

Answer 8

By the difference in the airflow across the air foil

Question 9

What is lift

Answer 9

The upwards force that supports the aircraft in the air. Counteracts weight

Question 10

What is weight

Answer 10

Force of gravity acting downward on the aircraft

Question 11

What is drag

Answer 11

The force that hold the aircraft back. Drag resists motion

Question 12

What is thrust

Answer 12

The force developed by the engine acts in the forward direction

Question 13

What is the imaginary reference line running down the center of the aircraft between the nose and tail

Answer 13

Longitudinal axis

Question 14

What is the lateral axis

Answer 14

And imaginary reference line running parallel to the wings

Question 15

What is the imaginary reference line that runs from the top to the bottom of the aircraft

Answer 15

Vertical axis

Question 16

What flight control controls roll on fixed wing and rotary wing aircraft

Answer 16

Ailerons (fixed wing) 
Cyclic stick (rotary wing)

Question 17

What flight control controls pitch on fixed wing and rotary wing aircraft

Answer 17

Elevators (fixed wing)
Cyclic stick (rotary wing)

Question 18

What flight control controls yaw on fixed wing and rotary wing aircraft

Answer 18

Rudder (fixed wing) 
Tail rotor (rotary wing)

Question 19

What does a flap do

Answer 19

Creates extra lift

Question 20

What does a spoiler do

Answer 20

Decreases or spoils wing lift by destroying smooth flow of air over the wing

Question 21

What do speed brakes do

Answer 21

Movable control surfaces that reduce the speed of the aircraft

Question 22

What does the tail rotor do

Answer 22

Counteracts the torque of the main rotor with horizontal thrust

Question 23

What do slats do

Answer 23

Allows the aircraft to be controlled at airspeed below normal landing speed

Question 24

What does AOA stand for

Answer 24

Angle of attack

Question 25

What is the angle of attack

Answer 25

The angle of the airfoil or fuselage meets a flow of air. Aids with landing

Question 26

What is auto rotation

Answer 26

A method of allowing a helicopter to land safely from altitude without using engine power

Question 27

What are the five basic parts of the hydraulic system

Answer 27

Remember PARTS 
Pump 
Actuator
Reservoir
Tubing 
Selector valve

Question 28

5 Main components of the landing gear

Answer 28

Shock strut
Tired
Wheel brake assembly 
Retracting and extending mechanism 
Side struts and supports

Question 29

What does a shock strut assembly do

Answer 29

Absorb the shock when landing

Question 30

What is motion

Answer 30

The act or process of changing place or position Motion is movement
