Which hydraulic system provides the operating pressure for the #1 engine thrust reverse?

• A. Blue system
• B. Yellow system
• C. Orange system
• D. Green system

Answer: (D)

The key idea is how thrust reversers are fed by dedicated hydraulic circuits. Each thrust reverser on the A320 is powered by its own hydraulic system to keep the two engines’ reverser functions independent. The #1 engine thrust reverse is supplied with hydraulic pressure from the Green system, which is designed to feed that left‑side reverser actuators. The other systems handle other actuators (for example, the #2 reverser is typically tied to a different circuit), while the Blue system powers different components such as certain flight-control or auxiliary hydraulic functions. The orange option isn’t part of the standard Airbus hydraulic layout, so it wouldn’t be the source for engine 1 thrust reverse.
