Delayed Reporting Time

If you're told of a delay before you leave your accommodation, your maximum FDP is figured from whichever of the original or delayed report time gives the shorter FDP — with fixed rules for delays under 4 h, 4–10 h, and 10 h or more.

Applies to 703704705 · in force since December 12, 2020

When the operator tells you of a delay before you leave your suitable accommodation to report, your maximum FDP is worked out from whichever of the original or the delayed reporting time gives the shorter FDP (700.52(1)). A delay can’t be used to extend your maximum FDP (AC 700-047 § 4.56).

Worked (AC 700-047 § 4.57): initial report 06:00, delayed to 09:00 (3 h delay) → FDP begins 09:00. Initial report 06:00, delayed to 12:00 (6 h delay) → FDP begins 10:00 (06:00 + 4 h).

Delay of 10 hours or more

The delay counts as a rest period if (700.52(3)):

  • you’re told before you leave the suitable accommodation, and
  • the operator doesn’t disturb your rest before a time you’ve agreed.

If there’s no agreed time, the operator may only contact you (700.52(4)):

  • in the 30 minutes before you were originally scheduled to leave the accommodation, or
  • in the 60 minutes before the original reporting time.
Regulation text — CARs 700.52

Reproduced from the consolidated Canadian Aviation Regulations ( SOR/96-433) on the Justice Laws website. CARs 700.52 verified Jan 15, 2026

700.52 (1) If an air operator advises a flight crew member of a delay in the member’s reporting time before the member leaves their suitable accommodation to report for duty, the duration of the flight duty period shall, for the purposes of determining the maximum flight duty period in accordance with section 700.28, be calculated starting from either the initial reporting time or the delayed reporting time, whichever results in the shorter period.

(2) Despite subsection (1), the flight duty period shall begin, if the delay in the reporting time

  • (a) is less than four hours, at the delayed reporting time; or
  • (b) is four hours or more but less than 10 hours, four hours after the initial reporting time.

(3) If the delay in the reporting time is 10 hours or more, the duration of the delay is considered to be a rest period if the air operator advises the flight crew member of the delay before they leave the suitable accommodation, and does not disturb their rest period before an agreed time.

(4) Unless the air operator and flight crew member agree on a time when the air operator may disturb the member’s rest period referred to in subsection (3), the air operator shall not interrupt the member’s rest period other than

  • (a) during the 30-minute period before the time the member was initially scheduled to leave the suitable accommodation; or
  • (b) during the 60-minute period before the initial reporting time.
What changed in 2018

In plain language

New with the 2018 rules: a structured way to handle a delayed reporting time without letting the delay be used to extend the maximum flight duty period.
