What is the required climb gradient for departures?

The required climb gradient for departures, as specified in regulations, is generally established at 200 feet per nautical mile (ft/nm). This climb gradient represents the minimum performance level that an aircraft should achieve during the initial climb phase after takeoff to ensure obstacle clearance. It is essential for pilots to be aware of this requirement as it directly impacts flight safety and operational planning.

Choosing 200 feet per nautical mile as the correct response helps ensure compliance with federal aviation standards and promotes safe departure procedures, particularly in environments where obstacles may be near the runway, such as hilly terrain or cityscapes. Pilots use this information during flight planning to determine if their aircraft's performance capabilities can meet or exceed this climb gradient while considering weight, runway length, and environmental factors such as altitude and temperature.

Higher gradients, such as 250 or 300 feet per nautical mile, might be relevant for specific airports or conditions, but the standard requirement outlined for most departures remains at 200 feet per nautical mile.
