    Hi,

    I tried standards Simbrief profile as well as other found online, but the passengers number is wrong when using the aircraft tab on the EFB after loading the Simbrief flight.

    59 instead of 69 for exemple.

    Any good profile available?

      Maybe passenger weight is different between the Bae 146 EFB and Simbrief.
      In Simbrief it´s also possible to include / exclude baggage weight with the Passenger weight.

      Try to compare the weight setups between the Bae 146 EFB and Simbrief.

        Yes, due to differences in pax and baggage weights and profiles, what is synced is the zero fuel weight and block fuel. So the total aircraft weight and thus performance will match your SimBrief OFP but the pax quantity won't necessarily match. That's always been the case for our aircraft.

          It's not just ith Justflight Aircraft this happens. This is a general issue with GSX.
          But once the weights are set equal in the Simbrief profile and teh EFB, it should work.

            @Martyn I still think something's weird. I've always had the 146-100 load 80 pax when importing payload from a Simbrief flight with automatic pax and cargo, and then filling up to something resembling the planned payload with cargo, equally splitting between front and rear compartment.

            My Simbrief profile is set up with a pax weigth of 79kg, which matches the new UNS-1 documentation (page 25) for what the plane assumes. Additionally, as I read it, Simbrief then adds 25kg of luggage per pax as cargo and some random amount on top. I tried setting the pax weight to 69 (lol) in Simbrief, and that netted a sub-80 head count after import.

            For an example with the default 79kg soul:

                                           WEIGHTS
                                           -------
                            EST      MAX     ACTUAL
            PAX              66              ......
            CARGO           1.7              ......
            PAYLOAD         6.9              ......
            ZFW            30.7     32.5     ......
            FUEL            3.9      6.5     ......  POSS EXTRA 2.7
            TOW            34.3     37.0  LDG......
            STAB TRIM                        ......
            LAW            32.5     35.2     ......
            
            

            (79kg * 66) = 5214kg
            (25kg * 66) = 1650kg
            sum: 6864kg

            Importing that yields (in the EFB) a load with 80 pax and 202kg in each front and rear cargo compartment, for a total of (80 * 79kg) + 404kg = 6724kg, so "ballpark correct", but still off.

              @Martyn Can I ask why you do it that way? It's a bit strange on my end and it's confused me previously about the F28. GSX can import specific passenger and cargo quantities from SimBrief OFPs so unsure why GSX can't load a JF aircraft with those values?

                A ditto vote here for me. If we're going for "immersion" then the loadsheet from simbrief (which is driven by my VA tasking) should surely be what is loaded? I've made sure to use the JF 146-300 SB profile so empty weights etc match. It's just a little confusing not to have numbers match when doing a check.

                  I found out that using those passenger weight value on the simbrief profile:

                  89kg for -100 and -200
                  88kg for -300

                  Will allow me to get the correct number of pax on the EFB, but I am still off by 200-250kg on the ZFW
