Directions: In the column on the left, record the aeronautical questions that need to be answered. In the column on the right, record the answer and include how it will change the model's design.

Aeronautical Question	Answer and effect on design
1. What forces act on an airplane?	1. Lift-weight, thrust-drag. They are oppositional. an airplane? The wings affect lift. The tail could affect drag. I might have to change the wing and tail size.
2. What is the CG?	2. CG = center of gravity. If the airplane is not balanced during flight, then it will pitch up or down or have a tendency to roll one way or the other. The airplane's wing placement, size of tail and size of wings can affect the CG. I might have to consider those changes to keep the airplane from doing (description of airplane's flight would go here).
3. What would cause an airplane to pitch?	3. If the nose pitches up, the tail could be too large or balanced during flight, then it will pitch up or down or have a tendency to roll one way or the other. The airplane's wing placement, size of tail and size of wings can affect the CG. I might have to consider those changes to keep the airplane from doing (description of airplane's flight would go here).
4. What would cause an airplane to roll?	4. The wings might not be centered evenly where they are attached to the fuselage. One wing might be heavier than the other. There may be more lift on one wing than the other.
5. If the thrust stays the same for each flight, how can I get more lift?	5. Change the weight of the fuselage. Change the size and shape (aspect ratio) of the wings.
