GATE Aerospace 2019 : Everything in brief

More than 12,00,000 students every year appear for GATE to get admission to M.Tech., MS, ME programs of IITs/NITs. Exam is conducted in 24 fields of Engg./Science and Aerospace is one of them (identified by code 'AE'). Around 5000 students appear for Aerospace paper to try their chances for roughly 150 seats.

Key Facts of GATE 2019 Aerospace Exam

  • GATE Aerospace exam will be conducted Online tentatively on 2nd February, 2019. Keep checking for exact date on GATE official website or here.
  • An online virtual calculator will be made available to students at the time of examination. No physical calculator will be allowed. The calculator can be opened by clicking this link. It has all the necessary functions like power (root, square, nth power, nth root etc.), trigonometric (direct & inverse), logarithmic etc.
  • Syllabus for Aerospace Engg. Exam (AE) is changed from last few years. It now has some Core Topics and Special Topics, with the weightage 90% & 10%.
  • Only the Final year students of B.Tech./BE/M.Sc. (or who have already completed the degree) are eligible to apply.
  • GATE Score will be valid for 3 years.

Who can appear in GATE Aerospace Exam?

B.Tech. in Aerospace Engg. is not a pre-requisite for appearing in GATE aerospace exam.  For example; to take admission at Aersopace Dept, IIT, Bombay you may be a B.Tech. in Aerospace/ Mechanical/ Civil/ Electrical/ Electronics/ Instrumentation Engg. Also, after clearing AE exam you can take admission in Aerospace, Mechanical, Automobile engineering, Industrial design, Biotechnology, Physics, Mathematics etc. (Details in our Admission section)

Students enrolled for M.Tech/MS in IISc or IITs are eligible for a scholarship from Ministry of Human Resource Development (MHRD). Student is expected to carry out the assigned duties for Teaching and Research Assistantship (TA and RA).

The M.Tech./MS (Research) student currently carries a monthly stipend of Rs.12,400/- for 8 hours of work per week. For Ph.D. students the corresponding financial assistance (for Engg./Sciences/Social Sciences) is Rs.25,000/- for the first two years and there after it is raised to Rs.28,000/- respectively for another three years. 

What is the Syllabus?

It comprises of 6 major topics from undergraduate (BE/B.Tech.) syllabus

  1. Aerodynamics
  2. Flight Mechanics
  3. Structures
  4. Propulsion
  5. Space Dynamics
  6. Engineering Mathematics

There are 55 multiple choice questions from this syllabus totaling to 85 marks. 10  multiple choice questions are from General Aptitude and carry 15 marks. (Check Full syllabus and Paper pattern)

How much marks are required out of 100?

From the past year results, a score around 30-32  is enough to clear the exam. You will be called 'GATE qualified'. But to get a seat in premier institutions, you require something like 55+.


This was just the basic information to get you started. Look for more information in other posts.

GATE_AE_Pattern

Type of Questions

GATE Aerospace contains questions of two different types :

  1. Multiple Choice Questions (MCQ) carrying 1 or 2 marks each; Each of these questions will contain four answers, of which one correct answer is to be marked;
  2. Numerical Answer questions, where the answer is a number, to be entered by the candidate using the mouse and a virtual keypad that will be provided on the screen.

Marking Scheme

  1. For 1 mark MCQs, 1/3 mark is deducted for a wrong answer. For 2 marks MCQs, 2/3 mark is deducted for a wrong answer;
  2. There is no negative marking for numerical answer type questions.

Design of Questions

  • Recall: These are based on facts, principles, formulae or laws. The candidate is expected to be able to obtain the answer either from his memory of the subject or at most from a one-line computation.
  • Comprehension: These questions test the candidate’s understanding of the basics of the field, by requiring him to draw simple conclusions from fundamental ideas.
  • Application: In these questions, the candidate is expected to apply his knowledge either through computation or by logical reasoning.
  • Analysis and Synthesis: These can be linked answer questions, where the answer to the first question of the pair is required in order to answer its successor. Or these can be common data questions, in which two questions share the same data but can be solved independently of each other.

Seats in Aerospace Dept. at IITs/IISc

Admissions at Postgraduate level in Aerospace field are available at following institutes in India

  1. Indian Institute of Science (IISc), Bangalore
  2. Indian Institute of Technology Bombay (IITB), Mumbai
  3. Indian Institute of Technology Kanpur (IITK), Kanpur
  4. Indian Institute of Technology Kharagpur (IITKgp), Kharagpur
  5. Indian Institute of Technology Madras (IITM), Chennai
  6. Defence Institute of Advanced Technology (DIAT), Pune
  7. Madras Institute of Technology (MIT), Chennai

The student intake in Aerospace Dept. by these institutes vary every year; there are 44-48 seats in each institute but on an average 15-20 students are selected on the basis of GATE Aerospace Exam. Rest may go to Sponsored candidates or candidates qualified in other GATE papers. IISc offers only 15-20 seats in total for ME.

You can get the details in our Admissions section.

Virtual Calculators in GATE

"Your personal calculators are not allowed in GATE" - but a VIRTUAL ON-SCREEN scientific CALCULATOR will be there on your computer screen.

GATE organizing office has released details of this calculator and it will look like this

The calculator can be opened by clicking this link. It has all the necessary functions like power (root, square, nth power, nth root etc.), trigonometric (direct & inverse), logarithmic etc.

Working on a physical calculator is very comfortable but it could be little wacky using this on-screen calculator since most of us are not habitual of using mouse to do calculations. No need to worry though - "PRACTICE" is the word. Start from today, save this calculator page as a bookmark and use it for daily calculations. sadly it is not possible to save it in offline mode, so you'd always need an internet connection to use this.

Calculator is very intuitive to use, once you start practicing you'd get the knack of it. More information regarding the usage of calculator is available from GATE website. Hide your physical calculators and start practising on virtual calculator.

Wish you good luck for GATE Aerospace. Happy Gateing!!
