15 mins is NOT enough time to:
-Sign in and select correct flight plans
-Print off PLOGS, TAFS, METARS, NOTAMS etc (sometimes have to load paper or toner cartridge to the printer. Sometimes have to reboot the computer)
-Assemble paperwork and flight folder
-Sort out and staple up paperwork (sometimes have to mend or refill stapler)
-Sign and annotate same with crew names etc
-Check head/tail wind on wind charts
-Check PLOG uses correct wind component
-Check PLOG for correct aircraft, passenger number and cargo etc.
-Check PLOG for operational notes specific to destination airports
-Read TAFs, METARs to determine which runways in use at departure and destination airports
-Calculate fuel adjustments for track mile differences to opposite runway(s) if
reqd
-Check weather and NOTAMS and agree alternate
-Calculate RTOM if reqd
-Check if tanking sector
-Check aircraft servicability and deferred defects.
-Decide, calculate and agree on fuel figure
-Phone handling agent with fuel figures, check CTOT, stand and cargo.
-Brief crew
-Get in bus
15 minutes is barely enough time to even skim through all this. I will admit that I have missed airspace closures and level restrictions in the FIRs downroute because there isn't time to read all the NOTAMs thoroughly. We got away with that without having to make a tech stop, but we were lucky. In the past we used to carry a healthy amount of extra fuel so we had plenty of contingency, but now it has to be absolute minimum fuel, so a mistake at the briefing stage can be very embarrassing.
I now report well early just to get all this done to maintain OTP. Most others do the same or download everything at home to read before driving to work.
File an MOR? yeah good luck with your career !
