What is the fixed altitude threshold used for determining the sterile flight deck light status?

• A. 5,000 feet
• B. 10,000 feet
• C. 15,000 feet
• D. 20,000 feet

Answer: (B)

The threshold is 10,000 feet. The sterile flight deck light status is tied to this fixed altitude so that below 10,000 feet the cockpit enters sterile mode, encouraging the crew to minimize nonessential chatter during critical phases (takeoff, approach, and low-altitude flight). Once you climb above 10,000 feet, the sterile restriction is removed and normal cockpit discussions can occur. The other options don’t match the standard rule, which centers on maintaining heightened focus during the lower, more demanding phases of flight.
