The airframe of a fixed-wing aircraft is generally divided into what total number of principal units? 1. Five 2. Six 3. Seven 4. Eight Which of the following is NOT a common design class of naval aircraft fuselages? 1. Monocoque 2. Semimonocoque 3. Reinforced shell 4. Welded steel truss In a semimonocoque fuselage design, primary bending loads are absorbed by what structural 1. Bulkheads 2. Longerons 3. Station webs 4. Vertical rings member? The shear load on a reinforced, shell-type fuselage is primarily carried by what structural component(s)? 1. The keel 2. The skin 3. The formers 4. The stringers Where on an aircraft is fuselage station 0 (zero) usually located? 1. Directly below the pilot 2. Above the nose landing gear 3. Above the main landing gear 4. At or near the nose of the aircraft Engine loads, stresses, and vibrations are transmitted to an aircraft structure by what parts? 1. Bulkheads 2. Mount beams 3. Engine mounts and nacelles 4. Stringers, formers, and frames 1-7. 1-8. 1-9. 1-10. 1-11. 1-12. What are the principal structural metiers of a cantilever wing? 1. Spars 2. Rings 3. Formers 4. Stringers The skin of a cantilever wing is fastened to which of the following structural components? 1. Ribs 2. Spars 3. Formers 4. All of the above The load imposed on the wings during flight acts primarily on what structural member(s)? Beams 2. Spars 3. Skin 4. Ribs Where on an aircraft is wing station O (zero) located?

Inches 3. Meters 4. Centimeters What is the primary function of the stabilizers? 1. To provide drag for the aircraft 2. To control the direction of flight 3. To balance the weight of the wings 4. To keep the aircraft flying straight and level 1 1. 1.
