How to log Relief Pilot / Supernumerary?

Modified on Fri, 26 May 2023 at 11:32 AM

If you operate long haul with augmented Flight Crew, you may have to log Relief Time (REL) / Supernumerary (SNY).  

Relief Time

CrewLounge PILOTLOG considers Relief time as Rest time, the time that you were not at the controls.


Depending on your aviation authorities, relief time may, or may not, be considered as flying experience. With PILOTLOG you have the option:

  • on the Settings - Flight Logging page, select "Deduct Relief from Total Time" to subtract all Relief (rest) time from your Total time and your Aircraft time (multi-pilot, multi-engine, etc). The hours on the Totals page, on various Reports (PDF) and in your Logbook (PDF) are deduted.

Note that you should always log the entire Total Time when recording the flight with CrewLounge PILOTLOG!

     e.g. you perform a 14 hours flight from LHR 07:00 to LAX 21:30

You must log Total Time 14 hours and function time as (as example) 4 hours in the right-hand seat (log as SIC time), 6 hours in the left-hand seat (log as PIC time) and 4 hours rest time in the bunk (log as Relief time)   

Total Time:    14:00

PIC:                4:00

SIC:                6:00

Relief:             4:00

By selecting "Deduct Relief" on the Settings page, this flight is printed in your logbook with a total time of 10:00 hours instead of 14:00.


You can configure PILOTLOG to automatically load Relief time as a percentage of Flight Time.  The autoload function will apply the percentage on Air Time (if logged), else on Total Time.

Enable the autoload function from the Settings page and again on the Tables - Aircraft page for each aircraft registration on which you want the autoload to work.  (e.g.  you can choose to autoload Relief time on all wide-body aircraft, but not on narrow-body).  Use the Multiselect function to mass-edit this property for all selected aircraft.  (read more)

Flight Time Limits

The same logic is valid for Flight Time Limitations (e.g. 900 hours annually).  

With "Deduct Relief" selected on the Settings page, the Relief time is taken out of your total time.  There is no need to setup any additional field, such as "stick time".  Instead, log Total Time and Relief Time.

Logbook - SNY

In order to print the code “SNY” in the Holder’s Operating Capacity column of your logbook, typically UK formats, you need to log "SNY" in the Type of Operations for the concerned flight.
