Heavier-Than-Air CraftHeavier-Than-Air Craft• Most abundant
aircraft• Takes more
energy to keep them in the air
• Easier to control• Gliders, Planes,
helicopters

AirplanesAirplanes• Works on the principles
of lift, gravity, thrust, and drag
• Can be agricultural or personal
• Speed range 7 mph to Mach 6.7
• Can have more than one wing (Biplane)
• Can seat hundreds of people

HelicoptersHelicopters• More access to places• Vertical take off and
landing• Can “hover” in the air• Rotating wings (rotary
blades) make it fly• Tail (auxiliary) rotor
keeps the vehicle from spinning with the blades

ReviewReview
• What are the two types of Air Craft?• What are the 4 forces on a plane and
where are they located?• What are the three controls of a
plane and what do they control?• What does aerodynamic mean?
