What is the standard IFR climb gradient?

The standard IFR (Instrument Flight Rules) climb gradient is typically considered to be 200 feet per nautical mile (NM). This standard is established to ensure safe terrain clearance during the initial phase of climb after takeoff. A climb gradient of 200'/NM allows for an effective climb that can accommodate various factors including aircraft performance and different airport environments.

When operating under IFR, pilots are required to adhere to this climb gradient for obstacle clearance unless otherwise specified by the procedure in use. This gradient is crucial for minimizing risks associated with obstacles in the vicinity of the airport and provides a standardized expectation that aids in both flight planning and the execution of departure procedures.

Pilots should be familiar with this standard as it helps them determine the required climb performance of their aircraft and allows air traffic control to manage air traffic flows safely.
