When trolleys are stationary, what must be done with the braking devices?

• A. They must be engaged
• B. They may be disengaged if the trolley is in the galley
• C. They should be turned off
• D. They should be checked only at pre-flight

Answer: (A)

When trolleys are stationary, engage the braking devices. Keeping the brakes on prevents any unintended movement from small bumps, turbulence, or crew activity in the galley, protecting people from injury and preventing the trolley from tipping or colliding with equipment. If you need to move the trolley, release the brakes to push it, then re-engage once it’s stopped. Brakes aren’t meant to be turned off or left disengaged while stationary, and securement isn’t something to limit to pre-flight checks—it's a ongoing safety practice during service.
