219 - ATPL Question Bank in English - What can happen when a pilot repeatedly obtains less sleep than needed over several days?

Question 219 - Human Performance and Limitations - ATPL - Airline Transport Pilot Licence

Repeated exposure to the same duty schedule necessarily removes all impairment without recovery sleep.

Only the final night’s sleep matters; earlier sleep restriction cannot affect performance.

Sleep debt and associated performance impairment can accumulate, even when the pilot underestimates the effects.

A brief stimulating activity permanently cancels the accumulated need for sleep.
