It is this lapse in time from something not showing right and the brain working out what and acting correctly in that!
It's ok if you have plenty of air below the aircraft but critical if you are IMC close to the ground!
I don't know about others but on early morning flights we can roll out of bed and be up at the airport 30 minutes later entering a cold aircraft often in the dark!
I hate that transition from being in sleep mode to wham everything is happening at once and the brain being expected to be in supercharge mode! When it's still probably stuck in the in bed mode 30 minutes earlier ))
It would be interesting to know whether that gap in something going wrong and the brain working out what extends on first flight of the day early morning ?
