Which statement is true regarding hydraulic system color coding on the A320?

• A. Yellow provides normal landing gear extension and normal brake system pressure.
• B. Green provides parking brake operation.
• C. Green provides normal landing gear extension and normal brake system pressure.
• D. Yellow provides anti-skid operation.

Answer: (C)

In the A320, hydraulic systems are color coded to show which system provides pressure for specific functions. Green corresponds to System 2, and it powers the normal landing gear extension as well as the normal brake system pressure. That’s why the statement that green provides normal landing gear extension and normal brake pressure is the correct one. Yellow is associated with a different hydraulic system and does not govern these functions, so claims about yellow handling landing gear extension or anti-skid operation aren’t accurate. Anti-skid is a brake-control feature that uses the brake system, but it isn’t defined by the color code for these primary hydraulic functions.
