Objective:
To better understand the four forces of flight and improve the student's skill of controlling them.
Elements:
- Thrust
- Forward force
- Powerplant and Propeller
- Drag
- Rearward force
- Opposes Thrust
- Parasitic vs. Induced
- Weight
- Downward force
- Center of Gravity (CG)
- Lift
- Upward force
- Opposes Weight
- Dynamic effect of air acting on the wing

Notes:
In steady, unaccelerated flight, the SUM of all forces is equal.

FALSE: |
The forces are equal. |

TRUE: |
Once force is not being overcome by the opposing force. |
