In this issue of our series “Know your CWA” we take a closer look at “Standby (SBY)” and “Reserve (RES)”. The CWA distinguishes between:

• Home Base Airport Standby
• Standby other than airport standby and
• Reserve

B1-36.7 Standby
B1-36.7.1 Home Base Airport standby
The following applies to Pilots on airport standby:

  • Airport standby shall be in the roster and the start and end time of airport standby shall be defined and notified in advance to the Pilots concerned to provide them with the opportunity to plan adequate rest.
  • The maximum duration of airport standby is 8 hours.
  • A crew member is considered on airport standby from reporting at the reporting point until the end of the notified airport standby period.
  • Airport standby shall count in full as duty period.
  • Accommodation is provided to the crew member on airport standby.
  • The response time between call and FDP start is 30 minutes to account for physiological needs.
  • If not leading to the assignment of an FDP, airport standby is followed by a rest period.
  • If an assigned FDP starts during airport standby, the following applies:
  • The FDP counts from the start of the FDP. The maximum FDP is reduced by any time spent on airport standby in excess of 4 hours.
  • The maximum combined duration of airport standby and assigned FDP is 16 hours unless the FDP has been extended due in-flight rest or split-duty.
  • The Pilot has to be reachable by phone during Standby.

Limitation for airport standby in addition to any other standby will be 3 times per year and no more than 2 consecutive days.

B1-36.7.2 Standby other than airport standby
The following applies to Pilots on standby other than airport standby:

  • The maximum duration of standby other than airport standby is 8 hours.
  • The combination of standby other than airport standby and FDP does not lead to more than 18 hours awake time. Full standby time will be considered in the evaluation of the pilot’s alertness level under FRMS.
  • 25% of time spent on standby other than airport standby counts as duty time for the purpose of Flight Times and Duty Periods limitations.
  • Standby is followed by a rest period.
  • Standby ceases when the Pilot reports at the designated reporting point.
  • If standby ceases within the first 6 hours, the maximum FDP counts from reporting.
  • If standby ceases after the first 6 hours, the maximum FDP is reduced by the amount of standby time exceeding 6 hours.
  • If the FDP is extended due to in-flight rest or to split duty, the 6 hours above are extended to 8 hours.
  • The Pilot has to be reachable by phone during Standby.
  • The response time between call and reporting time is minimum 2 hours.
  • Notifications of assigned duties should avoid interference with sleeping patterns if possible.
  • Suitable accommodation shall be provided if a Pilot is required to be on standby away from home base.
  • Pilots are expected to manage rest and nap opportunities while on standby. Therefore the beginning of the awake time correlates with the call out time.
  • The exact hours that the Pilot is required to be on Standby duty will appear on his Roster.
  • During Standby duty, a minimum of 8 hours per day is counted towards the Pilot credit time limit.

Pilots may be scheduled for standby duties as per B1-36.7.2 above for minimum 1 day and maximum 4 days consecutively for no more than 5 times per calendar year. A Pilot cannot be scheduled for more than 7 standby days in a roster period.


Let’s have a look at the definitions first:

Standby is defined in Part III of the CWA as “Means a pre-notified and defined period of time during which a Pilot is required by the Company to be available to receive an assignment for a flight, positioning or other duty without an intervening rest period, as follows:
(a) “Airport Standby” means a standby performed at the airport or any other location defined by the Company with the exception of Standby away from Home Base
(b) “Other Standby” means a standby either at home or in a suitable accommodation.”

Reserve is defined as “Means a period of time during which a Pilot is required by the operator to be available to receive an assignment for an FDP, positioning or other duty notified at least 18 hours in advance.”

Accommodation is defined as “Means, for the purpose of standby and split duty, a quiet and comfortable place not open to the public with the ability to control light and temperature, equipped with adequate furniture that provides a Pilot with the possibility to sleep, with enough capacity to accommodate all Pilots present at the same time and with access to food and drink.”

Suitable Accommodation is defined as “Means, for the purpose of standby, split duty, and rest, a separate Hotel room for each Pilot located in a quiet environment and equipped with a bed, which is sufficiently ventilated, has a device for regulating temperature and light intensity, and access to food and drink.“


It can be summarized, that in case of Home Base Airport standby:

  • A maximum of 3 times per year a pilot can be scheduled for airport standby, which is limited to not more than 2 consecutive days
  • Airport standby must be clearly indicated in the roster
  • The maximum duration is 8 hours and shall count full as Duty Period
  • The pilot must be reachable during these times
  • Accommodation must be provided
  • If no FDP is assigned, airport standby is followed by a Rest Period
  • Notification time (from the phone call until reporting time) is minimum 30 minutes
  • If a FDP starts during airport standby, the maximum FDP is reduced by any time spent on airport standby in excess of 4 hours
  • The maximum combined duration of airport standby and a FDP is 16 hours, except if the flight crew is augmented or in case of split duty.

Standby other than airport standby can be summarized as follows:

  • Maximum of 5 times a year, between 1 and 4 consecutive days with not more than 7 standby days in one roster
  • Standby duty must be clearly indicated in the roster
  • Maximum duration is 8 hours and 25% of the time will be counted for the purpose of Flight Times and Duty Periods limitations (B1-36.1.2)
  • A minimum of 8 hours per day is counted towards the pilot credit time limit (B1-39.5.1)
  • Standby is followed by a Rest Period
  • The pilot must be reachable during these times
  • Notification time (from the phone call until reporting time) is minimum 2 hours
  • If standby away from Home Base, suitable accommodation must be provided
  • The maximum combined duration of standby and a FDP is 18 hours
  • Standby ceases when reporting at the designated reporting point
  • If standby ceases within the first 6 hours, the maximum FDP counts from reporting
  • If standby ceases after the first 6 hours, the maximum FDP is reduced by the amount of standby time exceeding 6 hours
  • If the flight crew is augmented or in case of split duty, the 6 hours above are extended to 8 hours.

B1-36.8 Reserve
B1-36.8.1 The following provisions apply to Pilots assigned to reserve duties:

  • Reserve is the period of time during which the Pilot is required to be available and contactable to receive an assignment for an FDP, positioning or other duty. Reserve periods are indicated on the roster.
  • The maximum number of consecutive reserve days is 7.
  • The maximum duration of any single reserve period is 8 hours per reserve day.
  • Before each period of reserve a minimum of an 8-hours uninterrupted rest is scheduled.
  • An assigned FDP counts from the reporting time.
  • Reserve times do not count as duty period for the purpose of rest requirements or flight times and duty periods limitations, but shall be

Pilots may be scheduled for reserve duty on days which are unschedulable or in lieu of a duty from which the pilot is de-assigned.

Reserve 2 is scheduled from 12:00 to 20:00 CET
Reserve 3 is scheduled from 16:00 to 24:00 CET

Reserve in a roster implies that a reserve period, which does not result in a duty period, may not be retrospectively considered as part of a recurrent extended recovery rest period.

During Reserve, a minimum of 8 hours per day is counted towards the Pilot credit time limit. The minimum time between notification during a reserve duty and start of the duty notified is 18 hours.


In case of Reserve, the following is applicable:

  • Maximum number of consecutive RES days is 7
  • Maximum 8 hours per day
  • RES must be clearly indicated in the roster
  • The pilot must be reachable during these times
  • Notification time (from the phone call until reporting time) is minimum 18 hours
  • An assigned FDP counts from reporting time
  • RES does not count for the purpose of Flight Times and Duty Periods limitations (B1-36.1.2)
  • 8 hours per day are counted towards the pilot credit time limit (B1-39.5.1)
  • Any RES that does not result in a Duty Period may not be considered as part of recurrent extended recovery rest period.
