I didn't knw so much about the aircraft before and here i am reading about it in so much detail for the first time. I think it's a great knowledge and it's also very much beneficial. we can find the information about many other different categories of topics on the Google.

This would be a good question guide for those who are studying in the field of aviation. at first, I was really flustered will reading these question because I have few knowledge when it comes to aircraft, this list would be a good help for gathering more information and a good review for those who are going to take a test relating to the topic.

I guess this is an overview of the entire list of questions before an aircraft is set to take off. There a lot of considerations that needs to be taken care of. An aircraft carries hundreds of lives so it is a must that it is really ready to go. We have witnessed horrible crashing of aircraft in the course of history. So it must be a lesson for all, especially for the airlines and the pilots to take the necessary precautions before taking off.
