4 A strong bond between two or more people refers to interpersonal 1+1+1=3
relationship.

Attraction between individuals brings them close and eventually results in a
strong interpersonal relationship. Communication is said to be the basis of
every interpersonal relationship. Infact, effective communication is the key to a
healthy and long lasting relationship and if individuals do not, problems are
bound to come. Communication plays a pivotal role in strengthening the bonds
of friendship among individuals. A relationship loses its charm if individuals do
not express and reciprocate their feelings through various modes of
communication. A healthy interaction is essential for a healthy relationship.

It is not always that an individual needs to talk to express his /her feelings.
Feelings can be expressed through non-verbal modes of communication as well.
Lack of communication breeds problems in relationships. We tend to assume
that others know what we want or how we feel.

12 TYPES OF COMPASS 2+1= 3

The navigational compass is an instrument that gives the necessary datum line
from which courses and bearings can be measured. Compass helps us to find
the direction of the ship at sea.

Types of Compass. Magnetic compass and Gyrocompass.

(a) Magnetic compass. It is a magnet freely suspended in a horizontal plane
which settles with one end pointing approximately to the true north. The
reading obtained does not give us the true north due to various external factors
such as earth’s magnetism and ships magnetic property. The north direction
obtained is called the Compass North.

(b) Gyro Compass. This instrument is a rapidly spinning wheel or gyroscope, the
axis of which is made to point along the meridian towards true north. Courses
and bearings, which are measured using a gyrocompass, are true provided
there is no error in the compass. It is measured clockwise from 000 to360.

13 Semaphore. Semaphore is a method of communication when within visual 1+1+1= 3
range and where radio or vocal communication is inappropriate. It is carried out
with the help of two flags and arms outstretched. Semaphore symbols are as
given below.

OR

Phonetic Alphabets. When the letters of the alphabet are read out it will be
observed that some of them sound very similar especially on radio telephone.
This can cause confusion when important messages are being passed. In order
to eliminate the ambiguity phonetic alphabets are used so as to ensure clarity
and exactness of messages.

3. The Phonetic alphabets are given below.

A– Alfa J -Juliet S - Sierra

B– Bravo K – Kilo T - Tango

C– Charlie L –Lima U -Uniform

D - Delta M – Mike V - Victor

10 The types of Aero-models are : (any two) 1+1=2
(a) Static models
(b) Control line models
(c) Radio Control (RC) models
(d) Gliders
OR

The following are the general safety code to be followed:- (any two)
(a) Not to fly model aircraft in competition or the presence of spectators
until it has been proven to be airworthy by having been previously
successfully flight-tested. 1+1= 2
(b) Not to fly model aircraft higher than approximately 400 feet within 3
miles of an airport without notifying the airport operator.
(c) Give right of way to, and avoid flying in the proximity of full-scale
aircraft. Where necessary an observer shall be utilized to supervise flying
to avoid having models fly in the proximity of full-scale aircraft.
(d) Where established, abide by the safety rules for the flying site and
willfully and deliberately not to fly my models in a careless, reckless,
and/or dangerous manner.
11 Radar is an object detection system that uses radio waves to determine 1+1= 2
the range, altitude, direction, or speed of objects. It can be used to detect
aircraft, ships, spacecraft, guided missiles, motor vehicles, weather
formations, and terrain.
In aviation, aircraft are equipped with radar devices that warn of
obstacles in or approaching their path and give accurate altitude
readings.
12 a) Operation Safed Sagar was the codename assigned to the Indian Air 1+1+1= 3

Force's strike to support the Ground troops during Operation Vijay that was
aimed to flush out Regular and Irregular troops of the Pakistani Army from
vacated Indian Positions in the Kargil sector along the Line of Control.

b) The East Pakistan Rifles and East Bengal Regiment became the Mukti
Fauj.

c) The angle between the chord line and the longitudinal axis of the aircraft is
called angle of Incidence
13 The following are the forces acting on an aircraft in flight: - (any three) 1+1+1= 3
(a) Lift is a positive force caused by the difference in air pressure under and
above a wing. The higher air pressure beneath a wing creates lift and is affected
by the shape of the wing. Changing a wing's angle of attack affects the speed of
the air flowing over the wing and the amount of lift that the wing creates.
(b) Thrust is the force that propels an object forward. An engine spinning a
propeller or a jet engine expelling hot air out the tailpipe are examples of
thrust. In bats, thrust is created by muscles making the wings flap.
(c) Drag is the resistance of the air to anything moving through it. Different wing
shapes greatly affect drag. Air divides smoothly around a wing's rounded
leading edge, and flows neatly off its tapered trailing edge this is called
streamlining.
(d) Weight is the force that causes objects to fall downwards. In-flight, the force
of the weight is countered by the forces of lift and thrust.
OR
a) Total reaction: It is one single force representing all the pressures (force per 1+1+1= 3
unit area) over the surface of the Aerofoil. It acts through the center of
pressure which is situated on the chord line.
b) Angle of Attack: It is the angle between the chord line and the relative
airflow undisturbed by the presence of Aerofoil.
c) Aerofoil: It is a body designed to produce more lift than drag. A typical
Aerofoil section is cambered on a top surface and is more or less straight at the
bottom.
