Fuel System Flashcards
The fuel system comprises three interconnected crash-resistant fuel cells;
a) Two forward tanks located under the mid passenger seats and an aft fuel cell located below and behind the aft passenger seat.
b) One forward tank located under the mid passenger seats and two aft fuel cells located below and behind the aft passenger seat.
c) One forward tank located under the mid passenger seats, one mid tank located under the floor between the mid passenger seats and the aft passenger seat, and an aft fuel cell located below and behind the aft passenger seat.
A) Two forward tanks located under the mid passenger seats and an aft fuel cell located below and behind the aft passenger seat.
