이 책을 만들게 된 이유는 현재 수많은 항공학도 여러분들이 자격증 취득을 위해 비싼 시험 응시료와 개인시간을 투자해가며 고군분투하는 모습을 보고 저 또한 힘든 수험생활을 겪어봤기에 조금이라도 여러분들에게 어려움을 해소시키고 실전 대비를 효율적으로 할 수 있도록 하고자 만들게 되었다. 또한 일부 잘못된 정보들로 문제에 대한 오류, 부정확한 정답들이 오고가는 모습을 보며 이를 바로 잡아야 할 필요가 있다는 것을 느꼈다. 실제 기출문제와 유사한 문제들을 비슷하게나마 복원 및 수록하여 실전 대비에 맞출 수 있도록 제작하였으며, 해당 문제에 맞게끔 해설도 모두 삽입하였다. 문답식으로 외우는 것이 아닌 해설도 한번 꼼꼼히 읽어서 혹시 모를 문제 변형에도 대비하였으면 한다.
