Top opportunity

Avoid steep turns at low altitude

Departure Climb 3

Below a thousand feet the aeroplane is slow, heavy and close to the ground. A steep turn loses lift, raises the stall speed and flattens the climb just when the gradient matters most. A normal turn on course is a rate one — fifteen degrees or so, twenty-five at the outside, this penalty is to acknowledge when a turn has stopped being a turn and become a manoeuvre.

Landing Summary

The Boeing 737-800 aircraft successfully landed on runway 33L at KBOS Logan International Airport, demonstrating exceptional piloting skills and adherence to standard operating procedures. The final approach was initiated from the southeast, heading 315.0° at a distance of 4 nautical miles and an altitude of 1,208 feet above ground level (agl).

The aircraft's approach speed and threshold height were well within the acceptable limits, with a threshold speed of 133 knots and a good threshold height. This ensured a smooth and controlled descent onto the runway. The touchdown distance of 443 meters was also within the expected range, indicating a well-executed landing.

The local weather conditions at the time of landing were characterized by a temperature of -5°C and a wind speed of 4 knots from 320°. However, the crosswind component was negligible at 0 knots, and the headwind component was 3 knots, which had a minimal impact on the landing. The pilots effectively managed the aircraft's speed and direction to maintain a very good runway touchdown alignment.

The touchdown speed of 131 knots was also within the acceptable limits, and the touchdown rate of -175 feet per minute (fpm) was well within the expected range. This indicates that the pilots maintained a controlled descent and touchdown, minimizing the risk of damage to the aircraft or injury to the passengers.

The total landing distance of 1,423 meters was 51% of the runway length, which is a relatively short distance considering the aircraft's size and weight. This suggests that the pilots executed a precise and controlled landing, minimizing the use of runway length. The runway rollout alignment was also very good, indicating that the pilots maintained control of the aircraft during the rollout phase.

Overall, the landing of the Boeing 737-800 on runway 33L at KBOS Logan International Airport was a textbook example of safe and efficient flight operations. The pilots demonstrated exceptional skills and adherence to standard operating procedures, ensuring a smooth and controlled landing.
