CAA Pakistan. paper pattern

Material for Guidance of Assistant Director (ATC ) Test in CAA Pakistan

NTS Paper experience for AATCO May 09, 2015

Part one: English portion: 30 marks

a) Comprehension:

six questions related to importance of packaging in marketing i-e attracts customers, helps to 

recognize brand name, makes specification easily accessible and finally makes consumers to 

identify their brand easily among other present products.

Question were like:

i) what is main idea of paragraph,

ii) which statement does not fulfills the arguments made in the paragraph

iii) in paragraph, “THEY” refers to

etc

b) Fill in the blanks related to tense, preposition and vocabulary; almost 7-8 Q.

c) Analogies 5-6 Q

d) Antonym like propel, unmerited

e) Synonym like pleasant=lovely

Part two: Physics portion 20 marks

Some questions that I remember along with their answers are as follows:

1) A body moves in circle with constant speed; Then which of the following is true:

a) Work done is zero (correct confirmed)

b) Velocity is constant

etc

2) a satellite moving around the earth in orbit. which one represents its orbital speed i-e (formulai 

were given in mcqs) and correct one was ( sqrtGM/R) which was option B

3) a rope of length (value was given) has tension 8oN and mass was given and frequency of waves 

was asked (this was related to “stationary waves in stretched string” and related formula that was 

being used in numerical was “f=(1/2l)( sqrt(F/M) )”

4) four particles move in a constant magnetic field with same speed; which will has highest deflection

a) a copper ion

b) helium nucleus

c) electron (correct confirmed)

d) proton

(the reson is that particles will deflects on the basis of their m/e value

electron has lowest m-e value so will deflect most)

5) superposition and constructive interference related numerical

6) organ pipe closed at one end having length (value was given) and speed of sound was given. 

Fundamental frequency of note was asked: (the formula for this numerical is “f=v/4l”)

7) numerical related to a projectile launched with speed (value was given) at an angle of 30 degree: 

what time will it require to reach the peak of trajectory

(for this question I am unable to find any formula or solution anyone having its solution method will 

be appreciated )

8) a train(or any object was given) at a distance (value was given) produces a sound whose speed is 

(value was given).what time will sound require to reach the listener?

(very easy question related to formula “t=s/v”)

9) a stone is thrown horizontally with speed 30 m/s. what will be its speed when it hits water surface 

after 4 seconds

a) 30

b) 40

c) 50

d) 60

10) A person in an elevator is moving with constant speed (value I think 20 m/s was given) leaves a 

stone at the height of (I think 4.9 m was given or some other value may be).what time will stone take 

to reach the surface?

(I solved it like that but does not know that it is right or not:

Vi=0, g=9.8 or 10, height or s=let 4.9 m: the ny 2nd equation of motion

S=Vit_.5gtsqr) If anyone has confirm solution then please share.

11) Numerical related to velocity at the base point of simple pendulum.

I have obtained 12/20 marks in the portion.

Part three: quick math 30 marks

1) If (x+y)/(x-y)= ½ then (xy+xsqr)/(xy-xsqr)=? I took x=3/2 , y= -1/2 and solved it

2) Which of the followinh is sum of three consecutive integres:

a) 17

b) 23

c) 30(correct as 9+10+11=30)

d) 40

3) X:y,y:z was given the x:y:z?

Part four: GK, airplane and aviation related questions; marks 20

a) 6 (not correct as I filled it but answer key made it wrong)

8,9 were given does not know exactly

2) Capital of china=Beijing

2) term empennage mean

a) I think nose/tail like something was given and this “a”option is right according to answer key;

3) gwadar is on -----side of makran valley

a)east

b) west(confirm correct by answer key since this was question# 91 or 92)

c) south

d) north

4) Arabian sea is located in which ocean=indian ocean

5) ATU stands for=antenna tuning unit

6) CVR stands for= cockpit voice recorder

7)ASCB stand for= avionics stansdard communication

9)HF is (single band (correct confirm by answer key) double, triple band)

10)ILS stands for=instrument landing system

(I marked internal landing system that was wrong)

11)aerodynamically stall means

12)K-2 in in(Pakistan (correct), india, Nepal,)

13)old name of KPK=NWFP

14) border between azad Kashmir and indian occupied Kashmir is=line of control

Take off affect by? Hot and humid, cold and humid etc etc.

Largest PIA destinations is in which province?

what happens when aircraft stall?

Largest pia dest. Province is punjab

cold and humid could effect the takeoff

ILS stands for?

Change of booking but not sure

ILS instrument landing system

COB= change of booking

ILS = instrument landing system
