The control surface droop effect during hydraulic failure on the A380

This is a mod I created that primarily adds the A380's hydraulic system, including the yellow and green hydraulic systems, RAT, EBHA/EHA. Many control surface activities rely on hydraulics or stable electrical current (for example, flaps require any available hydraulic pressure to operate, while slats require green hydraulics or EHA). Control surface droop is just one small function among many; I also included this in my Boeing 777 hydraulic function simulation，you can download the 777 hydraulic simulation mod from this post.

Hydraulic simulation mod for B777 (FS4 and FSG)

This is a mod for FS4 and FSG, including versions of the B777-300ER and the B777-200LRF. It features three hydraulic systems, as well as a RAT and mechanical backups. Hydraulic failures such as actuator, brake, and thrust reverser are simulated. The hydraulic function description of this module is as follows:

When the aircraft is cold & dark on the ground and hydraulic is failure , the ailerons and elevators will naturally droop.

Both engines can pressurize the left and right hydraulic systems,…
