A2-16. The commanding officer.
A2-17. The maintenance material control officer (MMCO).
A2-18. Administrative department, safety department, operations department, and main-
A2-19. Target, aircraft, avionics/armament, and line divisions.
A2-20. The commanding officer must be a naval aviator.
A2-21. Four divisions during peace time.
A2-22. The V-1 flight deck division.
A2-23. The V-4 aviation fuels division.
A2-24. The navigation department.
A2-25. The aircraft Intermediate Maintenance Department (AIMD).
A2-26. An admiral.
A2-27. The Chief of Naval Operations (CNO).
A2-28. A "yard" period is the time scheduled for periodic repair and refitting of an aircraft
A2-29. Underway replenishment by supply ships, carrier onboard delivery aircraft, or by
vertical replenishment helicopter squadrons.
A2-32. The aircraft has been modified four times.
A3-1. Newton's first law of motion, which describes an object's willingness to stay at rest
because of inertia.
A3-2. Newton's second law of motion, which describes the reason why, when equal force
is applied, a heavy object accelerates slower than a light object.
A3-3. If you inflate a balloon and then release it (without tying the neck), it will move op-
posite the direction of the escaping air (Newton's third law of motion).
A3-4. Bernoulli's principle states that "as fluid reaches a narrow or constricting part of a
tube, its speed increases and its pressure decreases."
A3-5. The flow of air is split.
A3-6. Lift is developed by the difference in air pressure on the upper and lower surfaces
of an airfoil. As long as there is less pressure on the upper surface than on the
lower surface, an aircraft will have lift.
A3-7. The four forces that affect flight are lift, weight, thrust, and drag.
A3-8. Roll, pitch, and yaw.
A3-9. (a) An airplane's angle of attack is changed by raising the nose.
(b) A helicopter's angle of attack is changed by increasing the pitch of the rotor
