What is the standard IFR climb gradient?

• A. 150 feet per NM
• B. 200 feet per NM
• C. 250 feet per NM
• D. 300 feet per NM

Answer: (B)

The standard IFR climb gradient is 200 feet per nautical mile. This standard is established to ensure safe aircraft operation during the initial climb phase under instrument flight rules. This gradient provides a reliable rate of ascent while allowing sufficient obstacle clearance within standard airspace. Following this guideline helps maintain a safe distance from terrain and obstacles during the climb, considering factors like airspace structure and safe separation from other aircraft. When pilots plan their departures and climb profiles, adhering to this standard ensures that all IFR operations remain safe and consistent within controlled airspace.
