Module 9. Human factors

The blood/alcohol limit is

  • 40 milligrams of alcohol per 100 millilitres of blood as the single universal limit applying equally to commercial aircrew, air traffic controllers and all maintenance engineers.
  • 20 milligrams of alcohol per 100 millilitres of blood as the single uniform limit for commercial aircrew, air traffic controllers and licensed aircraft maintenance engineers alike.
  • 20 milligrams of alcohol per 100 millilitres of blood for commercial aircrew, air traffic controllers and 80 milligrams of alcohol per 100 millilitres of blood for maintenance engineers.

Explanation

The blood-alcohol limits differ by role: a stricter 20 mg per 100 ml applies to commercial aircrew and air traffic controllers, while the 80 mg per 100 ml limit applies to licensed maintenance engineers. The options applying a single uniform figure to all groups are therefore incorrect.
