What is the standard TERPS IFR climb gradient?

The standard TERPS (Terminal Instrument Procedures) IFR (Instrument Flight Rules) climb gradient is established at 200 feet per nautical mile. This standard is set to ensure that aircraft can safely clear any obstacles in the departure path under instrument conditions. The gradient provides a consistent basis for designing instrument departure procedures, allowing pilots to plan and execute climbs effectively while maintaining safe separation from any terrain or obstacles in the vicinity of the airport.

The 200 feet per nautical mile standard supports the safe transition from the ground to the enroute structure, accommodating various aircraft types and ensuring compliance with safety regulations. Understanding this climb gradient is essential for flight planning, as it influences the minimum climb performance required by aircraft during departure.
