Intro to Flight

2. The side to side motion Of an aircraft
3. The upward force that keeps aircraft in the air
6. The study of the motion of the air and how it reacts to objects passing though it
10. An airship that has rudders and elevators, which are used to control the direction and altitude. It also has an engine.
11. The length of a planes wings from tip to tip
14. A situation where the angle of attack is too great and the wing quickly loses lift
16. A vehicle that transports through the air
18. An aircraft with rotating wings
19. An aircraft with stable wings but no power source

1. A natural force which has a downward effect on an aircraft
4. A nonrigid airship that collapses when not filled with gas. It uses Helium to provide lift.
5. The tendency of a planes wings to dip to either side
7. A fixed-wing aircraft kept in flight by an engine or other power source
8. The main body of a plane

12. The force produces by a propulsion system that moves an aircraft though the air
13. The up and down movement of the nose of an aircraft
15. The rotating wing on a helicopter that provides lift
17. The shape of a propeller blade or an airplanes wing
