What is the typical rate of climb/descent to reach assigned altitudes during IFR?

The typical rate of climb or descent during Instrument Flight Rules (IFR) operations is often between 500 and 1,500 feet per minute. This range strikes a practical balance between ensuring a steady and manageable ascent or descent while also allowing for compliance with air traffic control (ATC) instructions. Maintaining a rate within this range contributes to safety and efficiency, particularly in controlled airspace where traffic density may require precise altitude changes and adherence to established procedures.

Climbing or descending too slowly can lead to extended times in the maneuver, potentially affecting traffic flow and increasing the risk of not achieving altitude assignments in a timely manner. Conversely, climbing or descending at rates much higher than 1,500 feet per minute may be uncomfortable for passengers and could lead to procedural difficulties, including overshooting or undershooting assigned altitudes, thus complicating interactions with ATC.

The specified range also helps pilots maintain better situational awareness and control over the aircraft’s performance, especially in less-than-ideal weather conditions often encountered during IFR operations.
