Crew Alertness monitor

MTBUR;

Reset the alarm with one of the Master WARNING/CAUTION Reset Switches on the glareshield.
Using any button or switch gets the time for the alertness monitor reset to zero.

Good feature for a long haul aircraft. I assume Hairbrush has a similar alarmclock.

But I doubt if this was the real problem here, could be just a blown up story. Hard to believe you can fly across Europe for that long without getting someone on the line.
