What replaces operable windows in the flight deck?

• A. Skylight hatch
• B. Side window replacement
• C. No replacement
• D. Overhead egress door

Answer: (D)

Modern flight decks replace operable windows with a dedicated overhead escape hatch (an overhead egress door) to provide a rapid, certified emergency exit for the crew. This design gives a secure, unobstructed path to the outside that meets safety regulations for flight deck evacuation, regardless of the main door status or cabin conditions. Side windows aren’t relied on for egress because they aren’t practical or safe as exits at altitude, and a skylight hatch isn’t the standard flight deck exit on this aircraft. There is indeed a replacement in place that fulfills the required emergency egress function.
