2. Airplane Flight: X-Plane in the Classroom

3. Power Loading Ratio of the plane’s weight divided by power

4. Power Loading Ratio of the plane’s weight divided by power Power or thrust overcomes drag to propel the aircraft

5. Power Loading Ratio of the plane’s weight divided by power Power or thrust overcomes drag to propel the aircraft Horsepower is a measure of power

6. Power Loading Ratio of the plane’s weight divided by power Power or thrust overcomes drag to propel the aircraft Horsepower is a measure of power Kinds of Horsepower

7. Power Loading Ratio of the plane’s weight divided by power Power or thrust overcomes drag to propel the aircraft Horsepower is a measure of power Kinds of Horsepower Brake Horsepower (bhp) = power to overcome drag

8. Power Loading Ratio of the plane’s weight divided by power Power or thrust overcomes drag to propel the aircraft Horsepower is a measure of power Kinds of Horsepower Brake Horsepower (bhp) = power to overcome drag Thrust Horsepower = bhp/80% (due to prop efficiency)

9. Power Loading Ratio of the plane’s weight divided by power Power or thrust overcomes drag to propel the aircraft Horsepower is a measure of power Kinds of Horsepower Brake Horsepower (bhp) = power to overcome drag Thrust Horsepower = bhp/80% (due to prop efficiency) Cruise Horsepower = Thrust Horsepower/75% (avoid full power)

10. Power Loading Ratio of the plane’s weight divided by power Power or thrust overcomes drag to propel the aircraft Horsepower is a measure of power Kinds of Horsepower Performance Tradeoffs Greater power, greater fuel consumption
