roulishollandais,
When you wake up in bed, you usually wake up gradually and find yourself in a (somewhat) familiar location, and have time to orient yourself to the day's tasks. Microsleep is nothing like regular sleep.
When you are driving and approaching a T intersection, you have to make a choice which way to go. If I microsleep just before the intersection and become aware again I must choose which way to go with no background information in memory except that the intersection might look "familiar."
In that case, my probability of choosing the correct direction is 50% based upon actual experience. It takes me several seconds after the turn to rebuild my navigation plan. As I said, I have lots of experience with microsleep
Proper use of coffee has now enabled me to avoid microsleeping, but you have to develop a plan how to mitigate the risk.
The guy who raised the gear on short final just made the wrong choice on reawakening from microsleep. Darn easy to do.
