Unless otherwise stated, what is the standard IFR climb gradient?

The standard IFR climb gradient is 200 feet per nautical mile. This standard is used to ensure that aircraft maintain a safe and adequate climb rate during instrument flight rules (IFR) operations. It's particularly important during departure phases when a clear ascent is necessary to avoid obstacles in the vicinity of an airport and to ensure safe flight navigation while under instrument flight conditions.

This standard measurement allows pilots and air traffic controllers to have a common understanding of climb performance requirements, facilitating effective communication and operational planning. It is crucial for ensuring that an aircraft can clear terrain while following prescribed departure procedures and routes safely. Knowing this standard helps pilots calculate the necessary altitude at specific distances during climb, contributing to overall safety and efficiency in IFR operations.
