10. What made you choose aircraft maintenance engineering/aerospace engineer line as your career?
In aircraft maintenance/aerospace engineering there are lots of interesting topics which include rocketry, aeroplanes, Lego’s. As a school student I started sketching for future aircraft and space craft,military aircraft. I analyzed the importance of space travel, aviation history, and aerospace industry and hence decided to get into this field.

11. Explain the day to day responsibilities of Aerospace engineering?
Each job profile even in aerospace industry differs from others. To mainly speak about aerospace there are two branches or field. One is aeronautical and other is astronautics engineering.

12. Explain the differences between Aeronautical Engineering and Astronautical Engineering?
Aeronautical engineering deals with vehicles which operates in the atmosphere
Aeronautical engineering deals with vehicles operating in space.
Aeronautical engineering works on tunnel tests, analyzing flight test data, manned space flights, planning future space missions, spacecraft operations, designing and testing robotic systems, developing new propulsion system, computing optimum flight trajectories,developing communication systems for distance space probes and designing new rockets.
Astronautical engineer includes designing power systems for spacecraft structure, developing communications systems for distant space probes, developing hardware skills for operations in spacecraft, designing and testing robotic systems, developing new propulsion systems and computing optimum flight.

13. Does the knowledge of mathematics of Science is required to get into maintenance engineering?

  • The basic understanding of Math is important as it is not used at all the time during the course of aerospace engineering. One should have a basic understanding of mathematical definitions and knowledge on computers is very important as the computer programs will help in doing simple calculations and verify the results are reasonable.
  • But on the science front it is very important to have a very good understanding on various subjects like dynamics and mechanics in physics, strong emphasis on chemistry,electromagnetism. For a good engineer one should know how law of forces makes things happen.
  • Also if you are good at physical sciences when opposed to life sciences like biology you will be a fit candidate for aerospace engineering.

14. Reasons for why patch work are in round in shape?
How would you handle if your co-worker is not co-operating with you?
Talk to your co-worker directly and explain him that you are having a problem working with him and make him understand the situation, if he is not willing to listen or not co-operating, then direct the issue to chief pilot.

15. What would you do if your Captain is not following the instructions properly?
Refer to your plane manual and discuss the same with your client and ensure you make him understand the procedures and rules. If he does not respond, you will call your concerned aircraft officer at the airport and escalate and make sure your voice frequency is recorded.

16. Without Air Traffic Control, what is the minimum descent rate of the plane?
A Pilot can descend up to 500” bare minimum, without informing the ATC (Air Traffic Controller) and this is only during an exceptional cases. However, it’s always better to be in regular touch with the Air Traffic Controller and to keep him informed about the descent rate. This will not have any traffic problems during landing in the runway.

17. What is Hard Landing? and Emergency Landing?
How would you handle the extreme pressure during emergency situation if you know that plane is not safe and it might crash anytime?
Few professions demand you to be selfless, and our respective clients would be the most important thing, that is why customer service differs completely in such fields compared to other streams. For example, Doctors, Lawyers, Pilots…these are the professions where employee saving your customer is the up most important thing.

So, as a engineer I fully understand my duties and responsibilities and will ensure that whatever panic situation I could be in, I will continue to deliver my duties till the end and ensure passengers are safe all times. Simultaneously I will own the full responsibility of maintenance of Air Craft safe and in the airworthy condition.

18. How many types of emergency landings are there and explain?
There are three types of emergency landings like:

  1. Forced landing: This is a situation where Air Craft engine fails and Pilot is forced to land the plane in the nearest airport.
  2. Precautionary landing: This is used when Pilot faces a problem due to severe weather conditions, or being lost in the air space traffic or due to lack of fuel or expecting an engine trouble.
  3. Ditching: This is when where Pilot cannot avoid this situation but to just land on water, which is safer than air bound.

19. You are a Flight Engineer? How important is to get the passengers switch off the mobile phones and laptops during land off? What could be the consequences?
It is very important to check if laptop and mobile phones are switched off or not, as the consequences can be bad….because interference of air crafts communication devices and electronic devices interfere with each other and there could be chances of not proper landing.
So, it’s highly recommended that all electronic and communication devices should be switched off during take off and landing.

20. What interests and abilities would help me as an Aircraft Maintenance Engineering/Aerospace engineer?
Successful aerospace engineers need lots of curiosity, problem solving skills,organizational skills, written and oral communication skills, people skills (as in leading and participating in teams) and computer skills. There are no physical requirements; in fact, we have many engineers with disabilities and it is not an issue for their job performance

21. What are the fringe benefits of aircraft engineer/aerospace engineering?
Good pay, good promotion potential, travel, respect from the community at large, and you get to say that you are a man with rocket science!

22. What are the disadvantages of being in aerospace industry?
The biggest disadvantage is that it is a relatively small field, and the number of companies in the field is getting smaller (lots of mergers between big companies in the news lately).
but now foreign companies are catching up; this means that American companies are streamlining their organizations in order to be competitive.

23. What Is The Difference Between An Aircraft Maintenance Engineering (ame) And Aerospace Engineering?
AMEs deal with maintaining the airworthiness of an aircraft and also certifying that it is fit for flight. Aerospace Engineering is concerned with designing and building an aircraft or spacecraft.

24. What Is The Body Which Issues The Licences?
The European Aviation Safety Agency (EASA) is an agency of the European Union (EU) with regulatory and executive tasks in the field of civilian aviation safety. EASA will issue the licence upon completion of training at an approved EASA part-147 training centre and with sufficient work experience in the aviation industry.

25. Which Parts Of An Aircraft Would I Be Maintaining As An Ame?
Your role as an AME depends on the licence you obtain when you complete the course. AME consists of 2 areas of study B1: Mechanical, B2: Avionics. A B1 licenced engineer would work on jet engines and aircraft systems such as electrical, flight controls, hydraulics and pressurization. On the other hand, a B2 licenced engineer would be responsible for the aircraft’s electrical, instrument, communication and navigation systems. When enrolling for your training, you may choose to enroll for either a B1 or B2 licence, or pursue a dual licence which is a combination of B1 and B2.
