I would never suggest that the scenario that you present is safe or unsafe.
OK, if I drink two Schlitz Malt Liquors while welcoming the passengers on board my airplane and maybe a third while taxiing to the runway, would that be safe, or unsafe? How about if I pased out for about 10 minutes on approach and final?
Just in case your AA's are run down in the breathalyzer - please allow me to refer you to the March 2003 Air Line Pilot magazine article reviewing the work of Dr. Rosekind and NASA Ames Center. Studies show that it takes two days to pay back a debt of fatigue and that the effects of fatigue are similar to the effects of excessive alcohol intake. First of all, the drunk usually is the last to realize their deficiency. There are measurable losses in decision making ability, judgement, memory, and efficiency of motor skills after 12 hours of duty which are the equivalent of 2 to 3 beers.
( in my best Barry White voice -
What's the Action - Satisfaction! ) Put a guy on 15:15 of duty, released to 9 hours of rest in domicile for another 16 hour day and you are looking at a pilot who takes "microsleeps" on approach.
You know that Crew Scheduling views these limitations as goals. They schedule without regard for sensibility, or fatigue considerations. It may be a lack of appreciation, or ignorance, of the problem - but you and I both know Crew Scheduling will push and extend, especially if the weather is bad.
Ah - I finally found the statistics in Aviation Week 16 July 2001 - Pilots getting 6 hours of sleep, rather than 8, performed as follows:
- Cognitive Errors - degradation of decision making ability - up 50%
- Memory reduced by 20%
- Ability to process communications - degraded by 30%
- Attention - reduced by 75%
So what do you suggest? Want to split a 6 pack with me in ops? Studies say there is no difference in performance.
Schedule with Safety! It isn't something I'm going to negotiate for.
