Study Notes
Forces in Level Flight
- In level flight, the four forces acting on an aircraft are lift, weight, drag, and thrust.
Lift Characteristics
- Lift acts through the center of gravity.
Trim Control
- Elevator deflection can be altered to provide an up or down load to trim the aircraft.
Drag Characteristics
- The increase in drag is known as CP (Center of Pressure) varying with angle of attack and CG (Center of Gravity) varying as fuel trim drag.
Optimum Flight
- Flying at the maximum lift/drag ratio means producing the most lift for the least amount of drag.
