JTL :
Your responsibilities as a professional crew member deny you the 'right' to micro sleep on final approach.
Are you for real my friend?
No matter how hard you think you are, if you are tired there is a chance you will micro sleep. This had been confidentially reported within the company I used to work for. A crew had reason to think that they had both gone to sleep on final approach!!!
It's all very well being a brave soul but you are responsible for a large number of people. Your above comment does not suggest a very responsible view on this subject.
Check out the latest issue of Flight International, a Fed Ex jet descended below the glide leaving the crew seriously injured. The cause of the accident was largely attributed to crew fatigue.
