How many operable windows are in the flight deck?

• A. Two
• B. One
• C. Four
• D. None

Answer: (D)

On the 787, cockpit windows are fixed and non-operable. They are designed as solid panels to maintain structural integrity and pressurization at altitude, while glare is controlled with electronic dimming rather than by opening a window. Ventilation for the flight deck comes from the environmental control system, not from an operable window. For emergencies, the crew exit through the cockpit door using the established egress provisions, not via a window. So there are no operable windows in the flight deck.
