Graduation Project Fatigue

[hanyaviation]

Dear pilots,

I'm currently doing my graduation project at the University of Amsterdam with the subject fatigue.
I want to obtain some experience of it from pilots, I made a little survey which takes 2 minutes to fill in.
The survey link: https://www.survio.com/survey/d/H3U5F0X9E7N6E1L6S
It will help me a lot.
Thanks in advance!!
