Term
| If two aircraft are flying with the same horsepower but at different altitudes, why does the aircraft flying at a higher altitude fly faster than the aircraft flying at a lower altitude? |
|
Definition
| Because at the higher altitude, the air is less dense therefore causing less drag on the aircraft. |

|
Definition
|
|
Term
| What type of material is usually used for construction of flight control surfaces? |
|

| What is used to round out the angle formed between the fixed tail surfaces and the fuselage? |
|
Definition
|
|
Term
| What structural unit provides a smooth airflow around and into the engine inlet? |
|
Definition
|
|
Term
| What component controls airflow around the weapons to reduce turbulence in the bay on some bomber aircraft? |
|
Definition
| Bay spoilers or air spoilers. |
|
|
Term
| How do doors differ from panels? |
|
Definition
|
|
Term
| Most transparent structures on an aircraft, such as canopies, windshields, and windows, are made of what two materials? |
|
Definition
| Transparent plastics or safety glass. |
|
|
Term
| How do paint removers and stripping compounds affect the plastic facings of a radome? |
|
Definition
| . It may adversely affect its electrical properties or strength. |
|
|
Term
| How are fuselage station numbers measured? |
|
Definition
| In inches from the reference datum or zero point on or near the aircraft nose. |
|
|
Term
| What are the three axes that an aircraft operates around? |
|
Definition
| Longitudinal, lateral, and vertical. |
|
|
Term
| What are the lateral control surfaces of the aircraft? |
|
Definition
| Ailerons, spoilers/speed brakes, and wing flaps. |
|
|
Term
| What controls all directional movements of aircraft? |
|
Definition
|
|
Term
| What primary flight control guides the aircraft about the vertical axis? |
|
Definition
|
|
Term
| Which type of stabilator has both sides connected together so that when one side moves the other side must move in the same direction and amount? |
|
Definition
|
|
Term
|
Definition
| It is a combination of an aileron and an elevator. |
|
|
Term
| What are five types of wing flaps? |
|
Definition
| Plain, split, fowler, slotted, and leading-edge slats or flaps |
|
|
Term
| What is the difference between leading-edge flaps and wing slats? |
|
Definition
| If the leading edge operates in conjunction with the trailing edge flaps, then you have leading-edge flaps. If they operate independently of the flaps, they are called slats. |
