I was forced to have a hiatus in my flying about 15 years ago due to ill health and it was a bloody nightmare.
No uni's would recognize my ATPL or had even heard of it for that matter. So I had to do my A levels first. Unfortunately my local A level college wouldn't recognize it either although they did let me do A levels on the strength of my 5 O levels.
Basically you will be dealing with academics who have never heard of the qualification and have no idea of the standard, effort and application that is required to obtain one.
Even know I look back and think that my chemistry teacher and Uni personal tutor never believed that I used to fly for a living.
Good luck.
