What is the specified Approach Climb Gradient for one engine inoperative?

The specified Approach Climb Gradient for one engine inoperative is 2.4%. This figure is critical for flight safety and performance calculations. The climb gradient is defined as the vertical rise relative to the horizontal distance traveled during a climb. A gradient of 2.4% indicates that for every 100 units of horizontal distance, the aircraft will have a vertical rise of 2.4 units, which ensures sufficient altitude gain to clear obstacles during the missed approach phase or when underway with one engine inoperative.

This requirement is derived from aviation safety standards that aim to ensure that aircraft maintain an adequate performance envelope in critical phases of flight with reduced power available. It is important for pilots and flight planners to have accurate understanding of these climb gradients to guarantee compliance with safety standards and obstacle clearance requirements based on aircraft performance capabilities.

Understanding the requirement of 2.4% helps pilots prepare adequately for different flight scenarios, ensuring a safe approach and climb even under less than ideal circumstances.
