What is the maximum landing rate for a 737?

Boeing 737 Landing Performance and Sink Rates

The Boeing 737 is a highly versatile and reliable aircraft, renowned for its excellent landing characteristics. To ensure optimal safety and performance, the 737 is designed with a specific landing profile that includes a target descent rate.

Recommended Landing Descent Rate

For optimal touchdown and flare control, Boeing recommends a descent rate of 600 feet per minute (fpm) for the 737. This recommended rate allows the aircraft to maintain a stable approach while providing ample time for the pilot to adjust the flight path as needed.

Maximum Landing Descent Rate

The 737’s landing performance is designed to accommodate a maximum landing descent rate of 600 fpm, decreasing to 360 fpm at maximum landing weight. This higher descent rate is typically employed in situations where it is necessary to manage excessive altitude or maneuver the aircraft to a specific landing point.

Hard Landing Threshold

While the 737 is capable of landing at higher descent rates, pilots generally consider anything exceeding 240 fpm to be a “hard landing.” A hard landing triggers a post-landing inspection to assess any potential damage or structural integrity issues.

Factors Influencing Descent Rate

The optimal landing descent rate can be influenced by various factors, such as:

• Aircraft weight: Heavier aircraft require a lower descent rate for stability.
• Approach conditions: Crosswinds, turbulence, or other adverse weather conditions may necessitate adjustments to the descent rate.
• Pilot technique: Individual pilot preferences and training can play a role in the selected descent rate.

Conclusion

The Boeing 737’s landing performance is optimized for a 600 fpm descent rate, with a maximum capability of 600 fpm at lower weights. Pilots generally aim to avoid hard landings exceeding 240 fpm to ensure the safety and integrity of the aircraft. Understanding and adhering to these recommended descent rates are crucial for maximizing landing performance and maintaining the longevity of the Boeing 737.
