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.
at my knowlegde second answer is correct? is it?
An individual suffering from stress when confronted with a task within his capability is likely to think the task is
- well within his normal ability.
- beyond his level of competence.
- someone else's responsibility.
If stress is defined as the difference between an individuals perception of the demands placed upon him and his actual ability to meet those demands, then if you are stressed, even though the task is within your capability, your perception is that it isn't.
The maximum allowable noise dose is
- a sustained noise level of exactly 85 dB for eight hours.
- any combination of noise and time which exceeds 90 dB TWA.
- a continuous noise exposure level of 70 dB for eight hours.
Maximum allowable cannot be OVER 90db twa? Surely 90db twa IS the max, not something OVER this level?

- Clinical research.
- Health and Safety.
- Error assessments.
Is it just me that I believe it is ergonomics? All this module is about the health of the LAE and the safetybat work. While there is no chapter for ergonomics.
