EXAMPLE PROBLEM AND SOLUTION
Conditions
Cruise Altitude ........................................ 4000 feet
Temperature ....................................................-9°C
Manifold Pressure................................. 33 inch Hg
RPM................................................................ 2400
Determine
1. ............................................................% of BHP
2. ...................................Fuel Consumption (GPH)
3. ..................................................... True Airspeed
Solution
