A350 MSFS 2024 - Loss of braking pressure during Dual Engine Failure

Hello iniBuilds Team,

I would like to report a bug regarding the hydraulic and braking logic on the Airbus A350 in Microsoft Flight Simulator 2024 during a dual engine failure scenario.

Issue description:

After experiencing a dual engine failure, I correctly started the APU. On the ECAM, the hydraulic pressure drops to the minimum allowed, but brake pressure is still indicated as available. However, when trying to brake after touchdown, the brake pressure fails to reach its maximum level. The aircraft accumulates almost no braking force and slows down very little, making it impossible to stop safely.

Temporary workaround found:

If I manually turn ON the Ground Electric Pumps (Emergency Ground Hydraulics) from the overhead panel, the system forces the hydraulic pressure back to high levels, and the aircraft is finally able to brake normally.

Real-world behavior:

With the APU running and available, the aircraft's electrical network should fully power the normal electric hydraulic pumps, restoring proper high pressure to the Green/Yellow systems and allowing full braking capability without needing to touch the ground maintenance switches.

It looks like the system logic is not correctly restoring full hydraulic pressure to the brakes when running on APU power alone during this emergency.

Could you please investigate this for the next updates? Thank you for your amazing work on this aircraft!
