General Awareness: This section of the paper will ask you questions related to latest happenings, current affairs of India and Aeronautic Industry, Major International and Nation Issues related questions, Social and Cultural GK, Economy and General Science etc.

Reasoning and English Section: This part of paper as the section name says will be all about English related MCQs and Reasoning questions, basically this part is focused upon Grammar, Sentence Improvement, substitution (one word), Analogy, words recognition and matching, Antonym, synonyms, comprehensive English, Idiom and Phrases, Error recognition and solving etc. Apart from this Paper will include some part of reasoning related questions that basically comes in competitive exams.

Syllabus for HAL MT Engineering Trades:
Part III syllabus for HAL MT Engineering Discipline: This section will have questions related to your specialization, as the Paper is MCQ based so the candidates appearing for the HAL MT exam are advised to study the basics of your specialization books. The standard of paper is made on graduate level so it is delimited with your recent study book syllabus. Below we have share some best objective guide books for HAL MT Engineering Discipline.

Part III Syllabus for HAL MT Human Resource: As said for the Engineering part the same rule applied here in this section, the paper will reflect questions from you’re the specialization subject that is HR, as the profile basically focused on the legal and Industrial relation so it is advised that to study Labour Law and Industrial relations. Consider buying the Objective Human Resource book that we have recommended for the HAL MT Exam preparation.

Hi Friends

First of all a very good luck to you. Although I didnt much take the exam seriously I would suggest you to work for it because its worth it!

I just gave the exam for Electronics branch n found it quite okay.. not at all impossible..

As you must be knowing, 40 questions comprising of English (grammar, synonyms etc), general knowledge (I dunno where they get those questions from!), general quantitative aptitude questions (series... quite easy ie. solvable if thought over). And rest 120 technical questions from:

- Control system engg (bode plot, nyquist, root locus etc...) * * *
- Mathematics (equation solvin, laplace etc) * * *
- Pulse n switchin circuits (schmitt trigger, etc..) and so on…

4 options given for each question n hell no negative markin!!! :-D

The ones I remember:

Hi Friends

I appeared for the HAL written test on 19th November 2008, Wednesday at All Saints College of Technology, Bhopal. It was a online test of 2.30 hrs.

As you know the paper pattern, 20 questions from Arithemetic and 20 questions from GK & Mental Ability and then 110 questinons hardcore technical from your stream, all having complextiy level "AVERAGE". FRIENDS, IT is not possible to remember all questions, thats why, I m just giving you some of the questions that I remember

1) first debut film of Hemamalini was _ a) dil ashina he b) sholay c) lal patthar d)xyz

2) which place is commonly known for "spice garden" ? a) sikkim b) tamil nadu c) kerala d) xyz

3) name of harry potter's 5th book is -- a) goblet of fire b) orfer of phoenix c) prisonners of azkban d) xyz

4) In India, before how much time, elections campaign are stopped before election day ?? a) 24 hrs before b) 48 hrs before ) 72 hrs before d) same day

5) It ......... rain later this afternoon. a) would b) shall c) will c) could

1 question was on blood relations and one was on sitting arrangements. Few arithmetical questions were there. Just go through RS agrawal's aptitude book and logical resoning book, also some questions were on series completion and some were like that find odd man out ???? *all were bit easy*

Now main thing is about technical !!!! I must say that one who is well prepared for exam like GATE, then there will be just a game to crack the HAL test becoz questions are bit easy. just you need to go through all the subjects of GATE, once you are well prepared, world is yours.

From digital electronics, hardly 2 or 3 ques were there. one was -- a diagram of half adder was given and two inputs A=1 and B=1 then find the value of sum & carry ?? very very easy*
2) questoins from BJT like find collector current Ic if Vbe is given and Rc is given also diagram was given in common emitter configuratil.*

So there are some easy questions but many of the questions are difficult ones. You will have to prepare, you can not learn from galgotia book directly. first make the concept clear and then practise to solve numerical questions. You will not get sample papers anywhere but questions are really easy, if you are well prepared. GATE level questions are very tough but don't worry.. such questions not came,, just think that if you are preparing for GATE, then you can do such questions very easily. There is not weigtage to any particular subject. sometimes mainly questions come from digital, sometimes from network, sometimes from electronics, so not sure abut pattern. You will have to make your command over all d subjects of GATE,, such as microprocessor even,, signals and systems,, friends,,easy questions will be done by everyone,, so don't overreact if you have done some of the easy questions, becoz only those are selected who have done tough questions correctly,, wild guesses will not going to work prepare n just prepare, all d best

Hi Friends

I m from ECE stream AND given this paper today. The first and last thing to clear this paper is that you have to be well prepare your technical knowledge not only concept but formulae also. One thing was gud that there was no negative marking.

The pattern was same as all person has told you. There was 120 technical questions, 20 aptitude and 20 from English cum General knowledge.

Some of them I remember:-

1.Which one is the oldest Ved.
a)Rig ved * *b)Arth ved * c)Sam ved
ans is a

2.Who is the Man behind Super man ????

3.Aryabhatt was lauched from?
a)usa * * b)R.s.s.a.
ans is a)

4.Flying any plane is prohibited on which building in India?
a)loksabha bahwan * b)India Gate * * * c)Taj Mahal
ans is c)

5.TODA tribals were found in?
a) manipur * b) jharkhand * c) sikkim
i think it shud manipur bt not confirmed

6.some questions on prepostions.

7.some on correct sentenses

8.one on conclusion of para.

In Aptitude just easy series, hcf, multiplictaions quite easy ones.

The most toughest part is Technical. I dont remember all the questions but still giving a idea how to prepare.

1. All equations of transistors actions (with numericals)

2. Diode equations, junction capacitance.

3. Op-amp in different modes like in negative feed back(with formulae).

4. FET Operation, Threshold *Voltage,and equation.

5. Control systems, Nyquist *criterion, Root locaii, Nicholas, Bode plot, Routh *Hurwitz Criterion.

6. Characterization of Control system based on transfer function and characterization

7. Effect of adding poles and zeros on the system stability.

8. Effect of lead and lag phase networks

9. Some questions about networks numericals for rms values avg values

10. Some questions on magnetism of a material,wire,magnetic field (numericals).

11. Some questions form EMFT on transmission lines,wave guides.

12. Trans conductance of transistor,hybrid model.

13. Questions on Tree, Graph in Networks.

14. Types of amplifiers like Class A,B,c.

15. Cascaded filters.

16. Convolution.

17. Numerical on sampling theorem.

18. Fourier series and long sinusoidal function and then tell the avg value of that signal.

19. RLC circuits with wattage *n calculate the currents n ...

20. AM, FM, Envelope Detectors n many more.

21. PI, PD, PID and the effect of derivative and integral cotroller action.

I Think Thats All You Have to be sound in all the above said.
