mroschk:
Hello,

i have some questions:

1. How do you estimate / count the number of passengers? Payload divided by Pax weight maybe ? If yes, what weight for one Passenger and how can i change it?

2. When i set my Airplane to a position at any airport, the Bugrad is nearly on the Stop Line of the Poition. But when i use the Marshaller, the Bugrad is far over the Stopline. Means he stops me too late.
What can be the reason for that? See screens

3. Last time i test the Catering Service and after the service was finished, the Catering Car crashes directly in the Wing of the airplane.
Can you avoid that if it is possible ?

4. Sometimes at the real airport, the Deboarding/Boarding and the Catering service is at the same time.
Is that also possible in  GSX?

Thanks
Matthias

Quoting from the GSX Manual, Page 21:


--- Quote ---Deboarding time

GSX will calculate Deboarding time by estimating the number of passengers on board, which equals to the sum of all the stations in the [weight_and_balance] section of the aircraft.cfg of the airplane in use, divided by 220 lbs. which is an industry standard method of calculating how much a single passenger + baggages weights, in average.

Quoting from the GSX Manual, Page 29:


--- Quote ---Estimate passengers number

If this option is disabled, GSX will always ask confirmation from the user about the number of passengers onboard. If the option is enabled, GSX will estimate the passenger number automatically, without asking confirmation. By default, the option is enabled, which mimics the standard behavior GSX always had until this version.

I cannot quote the whole paragraph here, but I suggest reading the "Understanding the Stop Position chapter", Page 39 of the GSX Manual

You don't say which airplane you used and how it was configured and you don't say which catering you are referring to (front or back ). With some smaller planes, the catering simply doesn't fit on the front door so, you should simply disable the door.

It's not. If it was, you would have complained the Catering Car would crash into the baggage loaders instead.

220 lbs is around 99 kg. The Passenger does not carry his Baggage into the Airplane.
So the weight is wrong calculated.
Can we have a settings in the GSX Settings dialog to set up the weight?
Also because it is calculated with different weights for different airlines.

I dont want to be asked for the Passenger number because 1 i have a homecockpit, so i dont want to use a keyboard and 2. as above , some airlines calculating with different weights. Prosim737, whiich i have to use, is calculating only 70kg/pax ( i know i is very less, bit not possible to change here )

Sorry, i dont understand that. Why do you taking the Pax Door into account??
The Stop position at the Airport are never used like this. The Stop position Lines at the Airport are alway for the Nose Gear, that is for sure.

Using Prosim737, so i just fly the 738, nothing else.
There are 2 Pax Doors on the Left side, which are oened always together, 2 Service doors on the right side, also opening always together and 2 cargo doors for the lower deck which i can open seperately.
So there are always 2 Service cars comming. But also the little Baggage Cars are driving under the Wings, which is not possible for a 737-800.

by the way :


--- Quote ---They stop the plane when their nose wheel reaches their stop line. Each aircraft has a different stop in line, which ensures that the jet bridge, from where the passengers disembark lines up with the main cabin door.

and


--- Quote ---Just expanding on Oliver’s answer, the jetways are flexible but have a certain range of movement closer to or further away from the terminal wall, as well as up and down. So the optimum parking location has been determined, and the marshaller (the guy with the wands), or the automated lighting system will tell the captain when his nosewheel is on the mark for his/her aircraft.

No, it's not.

The load IS correct, because loading stations in FSX/P3D represent BOTH passenger + luggage, so it is correct to divide by 220 lbs, which is the industry standard for how much a passenger + luggage weights, on average. We can only estimate, because the simulator doesn't provide with a payload TYPE, we don't know if a payload station is passenger only, luggage or just cargo.

This means. this calculation is not accurate only when the airplane has a "combi" configuration, which some cargo space. That's another reason why the "Estimate Passenger Number" exists.


--- Quote ---Can we have a settings in the GSX Settings dialog to set up the weight?
--- End quote ---

Not required. Since that weight is used only to estimate the passenger number, it's enough to disable the "Estimate Passenger Number" weight, so you can just set the final passenger number directly.

--- End quote ---

Then you can just set your airplane payload before the flight, so you won't have to confirm the passenger number.

Setting a different weight divider (something else instead of 220 lbs) won't solve anything, really, because the estimate will STILL be wrong if the airplane has a Combi configuration so, it's way more accurate to just override the passenger numbers.

In addition to that, GSX also allows airplane developers to set the passenger number directly, fully documented in the manual. The FS Labs Airbus use it already.


--- Quote ---Sorry, i dont understand that. Why do you taking the Pax Door into account??
--- End quote ---

Because having the passenger door in a predictable position (for jetways) is the main reason for having different stopping positions on ground. And no, we don't take "just" the preferred exit into account, but its RELATIONSHIP with the Nose wheel!


--- Quote ---The Stop position at the Airport are never used like this. The Stop position Lines at the Airport are alway for the Nose Gear, that is for sure.
--- End quote ---

The EFFECT is you'll see the front gear in different places depending on the airplane type. But what is *causing* this ? The CAUSE is having designed the different stop position taking into account the distance from the front gear in relationship to the preferred exit.

--- End quote ---

There's nothing in this sentence that contradicts what I said or how GSX works. In fact, it only confirms it.

If you customize a parking with a plane that has its preferred exit in a certain place, and place its nosewheel on a certain stop line, when you use the parking with ANOTHER airplane, which will likely have its own preferred exit and its own nosewheel in a different position, what you'll see is precisely what you are expecting:

- The nosewheel of the new airplane will go in a DIFFERENT stop position, exactly as it should.

- The preferred exit of the new airplane, instead, will be in the same position as it was the preferred exit of the airplane used to customize the parking, allowing for an easier jetway resolving, since if it resolves fine with that original airplane, it will likely work with the new one, unless they are very different in height, so a different jetway model with more reach might be required.
