Which two actions are required to arm GLD System Auto Deployment?

• A. System Armed and Thrust Levers Idle
• B. Thrust Levers Idle and Bleed Valve Auto
• C. System Armed and Radio Altimeter -7 Feet
• D. Thrust Levers in TOGA and APU Running

Answer: (A)

GLD System Auto Deployment is designed to activate only when the system is ready and the airplane is in a safe, power-off state. The two actions that satisfy this are arming the GLD system and having the thrust levers in idle. When the system is armed, it becomes eligible to deploy, but it will only actually deploy if there’s no thrust being produced, preventing unintended deployment during high-thrust phases like takeoff or go-arounds. The other options don’t fit because a bleed valve auto status isn’t part of the arming condition, a radio altimeter reading of -7 feet isn’t a valid or meaningful arming trigger, and having thrust levers in TOGA with an APU running places the aircraft in a high-thrust condition that doesn’t align with the safe, idle-state requirement for auto deployment.
