This page contains important easy to use graphs to assist pilots, student pilots and flight instructors with key principles for all fixed wing flight theory. Each graph also contains explanations. You can print, download and share this information providing the GoFly Online Logo is displayed.
Best Climb graph is similar to the Power available graph as it shows the relationship between power available and power required. It also shows the region of reverse command. The region of reverse command is also known as the back of the power curve. It is a dangerous slow speed region where any decrease in airspeed will see an increase in total drag and any increase in airspeed will see a decrease in total drag. This is the reverse of what happens in normal flight (cruise speed ).
This graph is identical to the ‘best climb’ graph, however it shows the relationship between maximum endurance and maximum range. Maximal range is the maximum distance an aircraft can fly with the available fuel less reserves. The Maximum endurance is the amount of time an aircraft can stay in the air with the available fuel less reserves. The graph also demonstrates the relationship between the airspeed to power required to maintain both maximum range and endurance.
