Human Performance

You can do a lot yourself to avoid flight-related stress and, as a result, acute

stress:

- Plan the trip in detail

- Make sure you have alternative options

- Ensure good working conditions – both before and during the flight
- Enjoy the trip – be positive

The limits for overload are highly individual. Some can constantly drive in high

gear, others have to downshift.

It is also important to know - and recognize - your limits.

2.6.4 Alcohol

We all know the effects of alcohol. Performance is reduced by even a small

amount of alcohol, and one of the first things you lose is your judgment when

you drink too much. The legal requirements state that no one with a blood

alcohol content of 0.20 or more may work as a crew member on an aircraft.

One thing is the alcohol content, another is a hangover after a night in the town.

It can easily take 24 hours before you are 100% “fit for flight” again after
drinking alcohol.

Normally, it is estimated that it takes about 1 hour and 15 minutes to burn off

one object, so you can roughly calculate how long a break you should take until

the alcohol you have consumed is burned off. There are no ways to burn it off
quickly.

In English, there is a good expression: At least 8 hours from bottle to throttle.
