Unless otherwise stated, what is the standard IFR climb gradient used in instrument procedures?

The standard IFR climb gradient used in instrument procedures, unless otherwise stated, is 200 feet per nautical mile. This gradient serves as a baseline for many standard instrument approach and departure procedures. Maintaining this climb gradient allows an aircraft to achieve a safe altitude within a predictable distance, which is essential for obstacle clearance and efficient air traffic management.

In practice, this means that for every nautical mile traveled horizontally, the aircraft should be climbing at a rate of 200 feet. This standard helps pilots plan their climbs effectively, ensuring compliance with air traffic control instructions and safe navigation through busy airspace.

By using this common reference point, pilots can also better coordinate with air traffic control, facilitating smoother and more efficient operations during departure and en route phases. It's important to note that specific procedures may require different climb gradients, and pilots must always refer to the relevant charts for specific instructions.
