Aviation is much more than being a pilot. Being a pilot is just a very small part of the entire crew that gets the plane in the air and keeps it there. the pilot may be the most visible part of the crew, but there are many people along with the pilot, each with a specific job and each equally important. It may only take from 1 to 10 people in the air to fly the plane, but they depend on a team that numbers in the hundreds on the ground.

Now the main issue is how can this all relate to your De'en and help you with preparing for the Akhira. Remember aviation is for many purposes. You could possibly become part of a crew that is in the process of bringing reknowned scholars to parts of the world that still need to be touched by Islam, you could be part of an effort that works to bring relief to suffering brothers and sister. You may not become a scholar, but you could be instrumental in getting scholars to where they are needed. You might not become a doctor, but you can be part of the means to bring doctors to where there are needed. You may not be an Imam, but you could be the means of bringing the Qur'an to those who are begging for it.
What a person does with job skills is their choice, you can use job skills for self indulgence or you can use them to prepare for the Akhira.
