Which statement best describes the operability of flight deck windows?

• A. They can be opened from inside
• B. They can be opened from outside
• C. They cannot be opened
• D. They are always open during taxi

Answer: (C)

The main idea here is that flight deck windows are fixed and not meant to be opened during normal operation. They’re designed to keep the cockpit sealed, which is essential for maintaining the aircraft’s pressurized environment and for security. Opening a window could compromise pressurization, expose the crew to wind blast and debris, and create security risks. Because of these safety and security requirements, the correct statement is that they cannot be opened. In practice, ventilation or communication with ground crews is handled through approved methods, and there’s a dedicated emergency escape path rather than using a window.
