Hello,

As an aircraft maintenance engineer so many works to do. Like they have to study aeronautical engineering or mechanical engineering department. Also go for training. There clear the medical fitness test. The medical fitness test occur because in aircraft so many situations comes like physically mentally technically etc. So this is time how they are handling the situation. Like if someone have minor diabetes but select all test may be they are in under observation. Because the glucose levels in body increase or decrease it's daily check. So if it's normal then may they should take them. But most of the cases Diabetic patients sudden fall in sugar level and sudden increase in sugar level they are not selected in this post. Infact so many job sectors like pharmaceutical industries some department also.

All the best.
