Of all the things GSX does, you consider separate passengers from baggage loading is the "main" one ? Nobody ever asked for it, in 10 years it has been out, I even checked all your forum posts, and there was nothing about it.

I'm sorry if I don't see lots of value in it, could you please explain why it would be useful ? Not that, I  think it will be very unlikely we'll do this change, surely not for release, because it would require massive changes in too many parts of the code, requiring months of troubleshooting and bugfixing, time that could be better spent to add much more interesting features, new services, new models, etc.

Instead, because we always listen when people DO post suggestions, we'll allow users to choose to Deboard Crew and Pilots or leave them on board in case of a turnaround, saving some time, because they won't have to exit the plane only to reenter shortly thereafter.

MANY users asked for it, so we'll add it, and in this case the fix was quite easy and reliable, because GSX was already coded to allow this, just it was only accessible to airplane code, not the normal GSX menus.

Justinthomas7:
Is this not a GSX level 3 thread?    Ie future expansion product with new features?  I must be mistaken and I regret making the suggestion with that hostile response.

On certain aircraft where refuelling and baggage loading/unloading cannot occur at the same time, this would allow more flexibility and ultimately more realistic as pax and baggage loading is not paired in real life either.   I didn't think it would be a big ask considering GSX will start pax boarding even if bag loading can't start due to refuelling.

Your only mistake is reading my reply as "hostile". Sure, you can post any kind of suggestion, and I replied that one was a bit small in value, but quite complex to make, so the cost/benefit ratio is very low. And I also asked you in which cases it could be useful, that's hardly an "hostile" attitude.

Which airplanes ? Why is done that way, exactly ? It's clearly not a very common procedure, and it surely goes against saving precious time so, there must be a sound reason.

Here's a few ACAPS charts that illustrates this. Page 124 for the Boeing 747-400.

Given that all four planes are primarily used for long-haul flights, the refueling takes the longest, and therefore would generally be started as soon as possible. The above charts would indicate that refueling is going on during cargo unloading and runs through cargo loading. Additionally, all four charts would indicate that the loading of the forward cargo hold starts long before passenger boarding starts. In the case of the 787, the chart would indicate that the forward and aft cargo holds are completely loaded long before passengers start boarding, as it is apparently bulk cargo that takes the longest. I should point out that the charts assume minimum turn time, and the airlines schedules would change the turn time accordingly. For instance, this video would seem to indicate that for this particular flight, the time the first jetway makes contact with the airplane to the time the last jetway is removed from the airplane is 1 hour 20 minutes.

That's not what the OP asked. He asked to decouple baggage/cargo loading from Passenger loading, nowhere he asked about refueling and nowhere I said it couldn't be done, because refueling is ALREADY a separate procedure for GSX, while baggage/cargo and Passengers are both part of the single BOARDING/DEBOARDING procedure and that's why I said THIS would require a massive rewrite of the whole GSX logic.

Refueling and Loading cargo can be done in certain cases, depending which side the refuel is located, but it's mostly a matter of preventing conflicts between the vehicles, so it might be more feasible to do, but that's not what the OP asked.

But that's only because in real-life the number of pallet is higher than GSX, which has a variable number of items, which never exceed 5 items so, it's unlikely cargo loading would take much longer than boarding 200+ passengers and, since they already work in parallel, the issue of having to start cargo loading because it will surely take longer than passenger is not happening in GSX.

That might change in the future, should we eventually made a product dedicated to cargo operation, with a more precise representation of the exact number of pallets, like we do with passengers, but it's not really useful in the context of how GSX currently work.
