Slide 3

Forces Forces acting on Aircraft (Level Flight) Lift Weight Thrust Drag

Slide 4

Forces (Level Flight)

Slide 5

Lift The upward force generated mainly by the wings that keeps the aircraft in flight.

Slide 6

Weight (Gravity) Force due to gravity cause by the weight the of the aircraft and all of its components This downward force caused by the weight directly opposes lift

Slide 7

Thrust The main driving force of the aircraft caused by the engines and its propellers This force is directly opposed by drag

Slide 8

Drag The opposite rearward force that is induced by the forward force of thrust Parasite Drag Drag caused by parts of the aircraft that dont contribute to lift (i.e. fuselage) Included Drag- Drag caused by parts of the aircraft that produce lift (i.e. wings)
