What is the recommended maximum speed for stability during climb under Operating Conditions T-4?

The recommended maximum speed for stability during climb under Operating Conditions T-4 is 210 knots. This speed is set to ensure that the aircraft remains within a safe operational envelope, fostering optimal aerodynamic efficiency and control while climbing.

At this speed, pilots can maintain a balance between altitude gain and engine performance, which is crucial during the ascent phase of flight. Climbing at speeds higher than the recommended limit can lead to increased drag and reduced climb performance, potentially compromising the aircraft's ability to maintain a stable trajectory.

Optimal speed management during a climb is essential for maintaining control and ensuring the safety of the flight, particularly when considering environmental factors such as wind and air density. In this context, the choice of 210 knots reflects careful consideration of these factors, making it the safest and most effective speed to operate under T-4 conditions.
