Tbh making the hanger deck 1m taller to compensate the ducting could possibly be worth a single island + extra parking spots / other benefits.SKB wrote:Now if QE had a single island with all that air ducting and trunking from two marine jet turbines to one island and funnel, her internal volume would be less. Maybe even a bit of floorspace might become lost or unusble with a decreased ceiling height too. Twin islands really do save space, at least below the flightdeck.
Then again, plugging in an extra 4.5m high hanger under the current could be worth it also.
