What is the local time window for a split duty rest opportunity?

• A. Between 2200 and 0500 local time
• B. Between 0600 and 1800 local time
• C. Any 6-hour window you choose
• D. Only at midnight local time

Answer: (A)

Split duty rest opportunities are scheduled within a fixed local-time window to protect sleep and support fatigue management. For this policy, the rest opportunity falls between 2200 and 0500 local time, a span that covers late evening into the early morning. This timing aligns with when most people can obtain a solid block of rest with less interference from daytime operations, helping crew recover between duties and maintain alertness on subsequent legs.

The daytime window (0600–1800) would disrupt circadian rhythms and busy daytime operations, so it’s not the designated rest period. Allowing any six-hour window independently would fail to ensure rest occurs within the specific, approved local-time window. Requiring rest only at midnight is too narrow and wouldn’t consistently cover the entire allowed window that crosses midnight.
