Aircraft

Question 1

Where is the nationality mark of an aircraft selected from?

Answer 1

The nationality mark shall be selected from the series of symbols included in the radio call signs allocated to the state of registry by the ITU. The nationality mark shall be notified to the ICAO.

Question 2

How is the registration mark constructed?

Answer 2

The registration mark shall be letters, numbers or a combination of letters and numbers, and shall be that assigned by the state of registry or common mark registering authority.

Question 3

Which combinations shall not be used in registration marks?

Answer 3

When letters are used for the registration mark, combinations shall not be used which might be confused with the five letter combinations used in the international code of signals, three letter combinations beginning with Q used in the Q code, and with the distress signal SOS or other similar urgent signals, for example XXX, PAN and TTT.

Question 4

how shall nationality or registration marks be applied to an aicraft?

Answer 4

The nationality or common mar and registration mark shall be painted on the aircraft or shall be affixed by any other means ensuring a similar degree of permanence. The marks shall be kept clean and visible at all times.

Question 5

What are the four forces affecting an airplane in flight?

Answer 5

Weight, drag, thrust and lift

Question 6

Explain thrust as a force acting on an aircraft in flight.

Answer 6

A manmade force that counteracts the drag. It is supplied by the power plant (engine)

Question 7

Explain drag as a force acting on an aircraft in flight.

Answer 7

A natural force that resists objects moving throught the air. It is not present in a vacuum and is determined by size, shape, speed, density of air and amount of friction.

Question 8

Explain weight as a force acting on an aircraft in flight.

Answer 8

A natural force acting downward and affects all objects in the air or on the ground. It is the force of gravity acting on an object

Question 9

Explain lift as a force acting on an aircraft in flight.

Answer 9

A man made force that counteracts weight. It is supplied by the wings and otherlift devices.

Question 10

What are the parts of an aircraft?

Answer 10

Landing gear, propeller, horizontal tail wing, vertical tail wing, main wing, flaps, airplane sensors,

Question 11

Who assigns registration marks to an aircraft ?

Answer 11

The state of registry or a common mark registration authority.

Question 12

Who assigns registration marks to an aircraft ?

Answer 12

The state of registry or a common mark registration authority.

Question 13

What are the wings of the plane and their function?

Answer 13

The wings are the most important lift producing part of the aircraft.

Question 14

What is the empennage of a plane and what is its function?

Answer 14

The empennage or tail assembly provides stability and control for the aircraft.

Question 15

What are the two main parts of the empennage?

Answer 15

The vertical stabalizer (fin) to which the rudder is attached;
The horizontal stabalizer to which the elevators are attached.

Question 16

What is the landing gear and its function?

Answer 16

The undercarriage or landing gear consists of struts wheels and brakes

Question 17

What are the nine recognition features of an aircraft?

Answer 17

1) Size
2) Number of engines
3) Wing Configuration
4) Wing Configuration
5) Tail Configuration
6) Position of Engines
7) Wing Placement
8) Fuselage Design/Shape
9) Landing Gear Configuration

Question 18

What are the ailerons and their function?

Answer 18

The ailerons are flap like structures on the trailing edge of the wings - one on each side responsible for making the airplane roll.

Question 19

Name all of the control surfaces of an airplane.

Answer 19

The control surfaces of an airplane are Ailerons, Elevators and a Rudder

Question 20

List the four wing types.

Answer 20

Straight Wings, Sweep Wings, Delta Wings, Swing-wing

Question 21

What are parameters for subsonic, transonic, supersonic, hypersonic?

Question 22

What does the amount of lift wings will get depend on?

Answer 22

1) Their Shape
2) Their Area
3) The density of air through which they fly
4) The speed at which air passes over them
5) The angle of attack

Question 23

How can lift be increased?

Answer 23

Lift can be increased in two ways:
1) By increasing the forward speed of the airplane
2) By increasing the angle of attack

Question 24

What is stability?

Answer 24

Stability is the ability of an airplane to return, of its own accord, to its original attitude in flight after it has been disturbed by some outside force, like wind gusts.

Question 25

What direction does the vertical finmaintain stability in? the horizontal stabalizer?

Answer 25

The vertical fin helps to maintain stability in the direction of yaw. The horizontal stabalizer helps to maintain stability in the directions of pitch and roll.

Question 26

In what form shall the letters and numbers of nationality, common and registration marks be?

Answer 26

The letters shall be capital letters in Roman characters without ornamentation. Numbers shall be Arabic numbers without ornamentation.

Question 27

What is rule pertaining to identification plate?

Answer 27

An aircraft shall carry an identification plate inscribed with at least its nationality or common mark and registration mark. The plate shall be made of fireproof metal or other fireproof material of suitable physical properties.

Question 28

What is rule pertaining to the position of an identification plate?

Answer 28

The identification plate shall be secured to the aircraft in a prominent position near the main entrance or:
a) in the case of an unmanned free balloon, affixed conspicuously to the exterior of the payload; and
b) in the case of a remotely piloted aircraft, secured in a prominent position near the main entrance or compartment or affixed conspicuously to the exterior of the aircraft if there is no main entrance or compartment.

Question 29

How shall marks appear on the wings of heavier than air aircraft?

Answer 29

On heavier-than-air aircraft, the marks shall appear once on the lower surface of the wing structure. They shall be located on the left half of the lower surface of the wing structure unless they extend across the whole of the lower surface of the wing structure. So far as is possible, the marks shall be equidistance from the leading and trailing edges of the wings. The tops of the letters and numbers shall be toward the leading edge of the wing.

Question 30

How shall marks appear on the fuselage on heavier than air aircraft?

Answer 30

On heavier than air aircraft, the marks shall appear either on each side of the fuselage(or equivalent structure) between the wings and the tail surface or on the upper halves of the vertical tail surfaces. When located on a single vertical tail surface, they shall appear on both sides. When located on multivertical tail surfaces, they shall appear on the outboard sides of the outer surfaces.

Question 31

What is rule pertaining to height of markings on a wing?

Answer 31

The height of the marks on the wings of heavier than air aircraft shall be atleast 50 centimeters.

Question 32

What is rule pertaining to marks on the fuselage?

Answer 32

The height of the marks on the fuselage (or equivalent structure) and on the vertical tail surfaces of heavier-than-air aircraft shall be at least 30 centimeters.

Question 33

What are slats?

Answer 33

Slats perform the same function of flats( they temporarily alter the shape of the wing to increase lift), but they are attached to the front of the wing instead of the rear. They are also deployed on takeoff and landing.

Question 34

Four types of slats?

Answer 34

Ventilated,Sealed, Droop nose, kruger

Question 35

What shape is a propellor blade?

Answer 35

A blade has an airfoil shape which generates lift as the blade slices through the air. Because the propeller is pointed forward the force generated is in a forward direction - that is it thrusts the plane forward.
