Flashcards in Block XIV- Fundamentals Of Flight Deck (30)
1
Q

What is acceleration

A

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

2
Q

What is speed

A

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

3
Q

What is velocity

A

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

4
Q

What is Newton’s first law

A

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

5
Q

What’s Newton’s second law

A

(Force) the change of motion is directly proportional to the amount of force and inversely proportional to the mass of the object being moved

6
Q

What is Newton’s third law

A

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

7
Q

What is Bernoulli’s principle

A

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

8
Q

How is lift accomplished

A

By the difference in the airflow across the air foil

9
Q

What is lift

A

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

10
Q

What is weight

A

Force of gravity acting downward on the aircraft

11
Q

What is drag

A

The force that hold the aircraft back. Drag resists motion

12
Q

What is thrust

A

The force developed by the engine acts in the forward direction

13
Q

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

A

Longitudinal axis

14
Q

What is the lateral axis

A

And imaginary reference line running parallel to the wings

15
Q

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

A

Vertical axis

16
Q

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

A
```Ailerons (fixed wing)
Cyclic stick (rotary wing)```
17
Q

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

A
```Elevators (fixed wing)
Cyclic stick (rotary wing)```
18
Q

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

A
```Rudder (fixed wing)
Tail rotor (rotary wing)```
19
Q

What does a flap do

A

Creates extra lift

20
Q

What does a spoiler do

A

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

21
Q

What do speed brakes do

A

Movable control surfaces that reduce the speed of the aircraft

22
Q

What does the tail rotor do

A

Counteracts the torque of the main rotor with horizontal thrust

23
Q

What do slats do

A

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

24
Q

What does AOA stand for

A

Angle of attack

25
Q

What is the angle of attack

A

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

26
Q

What is auto rotation

A

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

27
Q

What are the five basic parts of the hydraulic system

A
```Remember PARTS
Pump
Actuator
Reservoir
Tubing
Selector valve```
28
Q

5 Main components of the landing gear

A
```Shock strut
Tired
Wheel brake assembly
Retracting and extending mechanism
Side struts and supports```
29
Q

What does a shock strut assembly do

A

Absorb the shock when landing

30
Q

What is motion

A

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