ISSUE DESCRIPTION

Description of the issue:
When using the EFB quick fill sliders it is easy to overload the aircraft as they do not respect the MTOW of any aircraft that I have tried.

Ideally the sliders for both cargo, and seats, should obey the MTOW, and should reference each other. If you have 3% cargo, and seats at 3% is MTOW, the slider for both should now be locked, and not able to go above 3%.

One possible exception would be if you wanted to simulate a plane that really was above its MTOW. At the very least there should be better indication you are over MTOW, like the slider turning red. Maybe even a protection switch in options which physically stops the sliders exceeding MTOW, but can be disabled if you wish.

If applicable, which aircraft is experiencing this issue:
Any as far as I know.

[PC Only] Did you remove all your community mods/add-ons? If yes, are you still experiencing the issue?
N/A

FREQUENCY OF ISSUE

How often does this occur for you (Example: Just once, every time on sim load, intermittently)?
Every time

REPRODUCTION STEPS

Please list clear steps you took in order to help our test team reproduce the same issue:

  1. Open the EFB, and pull the sliders for seats/cargo to 100%.
  2. Observe the “Total mass” at the bottom of the EFB increase beyond the MTOW

YOUR SETTINGS

If the issue still occurs with no mods and add-ons, please continue to report your issue. If not, please move this post to the User Support Hub.

What peripherals are you using, if relevant:
N/A

[PC Only] Are you using Developer Mode or have you made any changes to it?
N/A

[PC, MSFS 2020 Only] Are you using DX11 or DX12?
DX12

[PC Only] What GPU (Graphics Card) do you use?
Nvidia 3090 FE

[PC Only] What other relevant PC specs can you share?
These shots are from the SU1 Beta, but I believe this affects the release version also.

MEDIA

Please add a screenshot or video of the issue occurring.

Images below are from the BN2 Islander setup, but the same issue is shown in the Cessna 172.

Full load of fuel, to 100%. This obeys the config files for the plane, and the maximum fuel tank capacities. 130gal for the example below.


With seats set to 0 i.e. not even the pilot, Cargo can be pushed up to 100%, and the plain is now at MTOW.

Remove all cargo, and now push Seats up to 100%. Plain is massively above MTOW.

The EFB settings page would be a good place to add a “Protect against exceeding MTOW” switch.

Is that the same issue than reported here ?: EFB Mass and Balance loading not working - "The loading of your aircraft failed, try again later"

I don’t think so, as I am not getting that error message at the top of the window. Their error may triggered by the same thing though. I get no errors when I load the aircraft, and can happily try taking off over three times over the MTOW.

Most probably it’s related to the same issues. If you check the whole thread in one I point out that weighs don’t make any sense hence you can completely overload the airplane. For me it’s the same, the whole thing doesn’t work.

• Yes

Provide extra information to complete the original description of the issue:
• I get the sense this is an SDK issue. At least for 2020 aircraft brought into 2024, there is a “type” that is specified for a station under station_load.N in flight_model.cfg. If that “type” is set to “1” Pilot or “2” Copilot, the SDK limits the weight of those individuals to 200 lbs. max. However, if the “type” is set to “3” Passenger the weight seems to be some fractional value of the overall payload capacity of the aircraft rather than a reasonable max human weight, such as those for the crew. I note that this max “passenger” value will fluctuate depending on the aircraft. I have not done the math to see what fractional value it is, but it is clearly varying by aircraft.

If relevant, provide additional screenshots/video:

Microsoft Stratoliner (with my mod):

Note: This must be tagged as a “2” Copilot, but labeled as “Front Pax”, which is a normal function of the SDK:

Whereas this must be tagged as a “3” Passenger:

Also some aircraft in the career mode like cessna 208b freight missions are overloaded or the runways are too short for takeoff or landing like pc12 cargo missions.
