Hi, I keep having issues with the landing spoilers and the hydraulic system. I’ve noticed that when I land and engage the thrust reversers, hydraulic circuit A (or sometimes circuits A, B, and C) loses pressure, causing the spoilers to retract; this happens while the flight engineer's auto-checklist is running, without the PTU or electric pumps kicking in.

Has anyone else experienced something similar?

Hi,

Thanks for your report. I will forward this thread to the team for further clarification.

Thanks for your patience!
