In which fuselage region is the main landing gear located?

• A. Center Fuselage
• B. Forward Fuselage
• C. Wings
• D. Aft Fuselage

Answer: (A)

Placing the main landing gear in the center fuselage puts the heavy, primary load along the aircraft’s centerline, which gives a stable load path during landing and braking and helps keep the aircraft’s weight balanced around its center of gravity. This central position also works well with carrier storage, since it leaves room for the wings to fold without interference with the gear bays and keeps the wing structure from having to carry the brunt of the landing loads. If the main gear were moved forward or aft, you’d introduce larger pitch moments and clearance issues; if it were in the wings, it would complicate wing folding and load distribution. So, the center fuselage location is chosen for optimal load distribution, stability, and compatibility with wing folding.
