Q

What is Lift?

A

The force that acts in an upward direction to support the aircraft in the air.

Liftmust be greater or equal to weight if flight is to be susutained

Q

Ailerons control what axis? Which controls what?

A

Longitudinal axis

Roll

24
Q

Elevators control what axis? Which controls what?

A

Lateral axis

Pitch

25
Rudders control what axis? Which controls what?
Vertical axis Yaw
26
What does the cyclic stick in the Helo control?
Roll / Pitch
27
What dose the Tail Rotor in the helo control?
Yaw
28
What do the Flaps do?
(Leading / Trailing Edges) Creates extra lift
29
What do the Spoilers do?
"Air brakes" slows aircraft to acceptable speed to land
30
What do Speed Brakes do?
Creates more drag for aircraft
31
What do Slats do?
Movable control surfaces that assist with lateral control of aircraft
32
Define an Airfoil
Curved surface that assists with creating lift
33
Define Collective
When all blades of a Helo move together to change Angle of Attack or pitch
34
Define Angle of Attack (AoA)
Angle at which the airfoil or fuselage meets a flow of air
35
Define autorotation
Method of landing a Helo without using power
36
What 5 components make up the hydraulic system?
- Reservoir - Pump - Tubing - Selector Valve - Actuating Unit
37
What 4 components make up the landing gear?
- Shock strut assembly - Wheel brake assembly - Retracting and extendiing assembly - Side struts and supports
38
State the safety precautions used when servicing aircraft tires
- Always approach tires from fore and aft - When inflating, stand off to the side - Deflate when removing from aircraft
39
Describe Turbojet
Projects a column of air to the rear of the aircraft to create thrust
40
Describe Turboshaft
Delivers power to drive something other than a propeller
41
Describe Turboprop
Conversion of gas-energy into mechanical power
42
Describe Turbofan
Same as a Turboprop, except the propeller is replaced by a duct-enclosed axial flow fan
43
What are the 3 types of fuel the Navy uses?
- JP-4 - JP-5 - JP-8
44
Characteristics of JP-4 fuel
Flame Spread Rate: 700- 800 ft/min Flashpoint: -10 degrees F or -23 C - Not used on ships - Lower RPM - Slower acceleration
45
Characteristics of JP-5 fuel
Flame Spread Rate: 100 ft/min Flashpoint: 140 F of 60 C - Used on ships - Primary jet fuel
46
Characteristics of JP-8 fuel
Flame Spread Rate: 100 ft/min Flashpoint: 100 F or 40 C
47
Describe the three hazards associated with jet fuel
- Fuel flames - Vapor inhalation - Toxic contact
48
What are the safety precautions and procedures associated with applying and removing external power
- Circuit breakers & switches must be in proper position in required MIMS - Inspect power cables and cable assembly pins - Ensure power sources is secured prior to application & removal - When using mobile power unit, ensure it is chocked
49
Discuss icing's effects on aircraft and its performance
Restricts aircraft's ability to move - Loss of engine power - Loss of radio - False indication on instruments - Loss of brakes
50
State the purpose of Pitot-static
Includes unstruments that opeerate on the principle of the barometer
51
State the purpose of the Airspeed indicator
Displays speed of the aircraft in relation to the air it's flying in
52
State the purpose of Altimeters
Shows the height of the aircraft above sea level
53
State the purpose of Rate-of-climb
Shows the rate at which the aircraft is climbing or descending
54
State the purpose of Attitude indicator
Shows the pilot the relative position of the aircraft compared to the earth's horizon
55
State the purpose of turn and bank indicator
Shows the correct execution of a turn and bank
56
State the purpose of Navigation systems
Direct, plot, and control the course or position of the aircraft
