For takeoff on RWY 9, what minimum rate of climb in feet per minute is calculated?

The minimum rate of climb required for takeoff is determined based on several factors including aircraft performance, weight, and environmental conditions. A rate of climb of 970 feet per minute is often a performance requirement that ensures a safe ascent over obstacles and allows sufficient clearance at the end of the runway.

This figure can be derived from the aircraft’s performance charts, which account for ideal conditions such as standard temperature and pressure. The rate of climb must be high enough to ensure that the aircraft can maintain a safe margin above terrain and any obstacles in the takeoff path. This is particularly important when taking off from runways with specific directional constraints, where climb performance might need to be higher to ensure safety.

Choosing a rate of climb of 970 feet per minute ensures the aircraft adheres to safety regulations and maintains operational integrity during its initial climb phase. It balances performance demands while considering potential hazards, making it a standard metric for pilots during takeoff procedures.
