Flight Score
Departure
Make small rudder corrections against a point at the far end to hold the centreline.
What happened: During the ground roll you drifted 59 ft off the runway centreline.
Watch for: Watch runway alignment against the centreline, correcting with small rudder inputs.
See Departure Roll
Arrival
Raise the nose more slowly in the flare and stop as soon as the sink is checked; if it balloons, hold the attitude.
What happened: The flare ballooned, with 346 fpm of sink returning after the arrest; a balloon like this usually carries through to a firm touchdown, as it did here at 521 fpm.
Watch for: The runway ahead: the aircraft still sinking gently towards it through the flare, never rising.
Arrive slow and the sink rate at the threshold is already above schedule, the flare is short because there is no energy to extend it, and the touchdown is hard in a way that feels exactly like a late flare. Diagnosing a slow arrival as a late flare is the catastrophic misread: you respond by flaring earlier, which bleeds more speed, which makes the next one worse. The tiebreaker is threshold speed against VRef, not feel. Never diagnose a flare without it.

The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
Two stabilised approach gates, each with seven checks, where the approach path is 1,000 ft and 500 ft above the runway.
The approach, gate by gate
Side view — the last 8,413 ft of the approach.
Plan view — the first 8,413 ft of the 10,560 ft runway, to the same scale as the side view.
Touched down 5,779 ft past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The flight commenced with a 39-minute taxi from the parking area to the runway at San Francisco International Airport (KSFO), covering a mere 0.9 nautical miles. The Boeing 737-800 then took to the skies, departing from runway 01L and lifting off at a speed of 143 knots (65% of the 4,754-foot runway distance). On a warm day with a temperature of 73°F, the aircraft embarked on its journey, bound for Phoenix Sky Harbor International Airport (KPHX).
Upon departure, the aircraft began its initial climb, rising from 983 feet to 24,791 feet above sea level over a distance of 42 nautical miles and in a span of 11 minutes. This initial climb marked the beginning of a series of ascents and descents, interspersed with periods of level cruising. The aircraft's next climb, which started approximately 2 miles south-west of Ridgemark, California, took the plane to 32,001 feet, an elevation gain of 7,200 feet over a distance of 63 nautical miles and in 9 minutes. Notably, the aircraft was at cruising altitude for an extended period of 47 minutes, covering 316 nautical miles.
However, the flight's journey was not without significant descent phases. A notable descent began approximately 1 mile south-east of Mesa Verde, California, during which the plane lost 19,942 feet in altitude over a distance of 142 nautical miles and in 25 minutes. Later, the aircraft underwent further descent phases, each lasting a few minutes and resulting in a loss of altitude. The plane landed on runway 26 at KPHX, which has a length of 10,560 feet. Landing parameters, including threshold height and speed, were slightly over or above target, with the touchdown point situated more than halfway down the runway. The plane experienced a heavy touchdown rate of -653 feet per minute but managed a controlled landing.
Upon examination of the landing details, it is clear that there was a considerable overrun of more than 50% of the available runway length (7,894 feet). While the touchdown speed was slightly high (139 knots), the rollout alignment was slightly misaligned from the centreline. The flight ultimately covered a distance of 642 nautical miles, using 10,840 pounds of fuel in a total duration of 116 minutes.
The Boeing B737-800 aircraft successfully landed at KPHX Phoenix Sky Harbor International Airport on runway 26. The approach to the runway began from the east at a distance of 4 nautical miles and an altitude of 1,252 feet above ground level (agl) with a heading of 270.0 degrees. The aircraft performed the landing within the required parameters, but there were some areas that needed improvement.
One notable concern was the excessively high threshold height, which was 123 feet agl, significantly above the target height. Additionally, the threshold speed was well above the target at 153 knots, indicating that the aircraft could have maintained a safer approach speed. This excessive speed could have contributed to a number of problems during the landing.
The touchdown point was also quite far along the runway, using over 50% of the available runway. This is a significant concern, as it increases the risk of running out of room before coming to a stop. The touchdown speed, although a little fast at 139 knots, was still within a manageable range. However, the touchdown rate was heavy at -653 feet per minute, which could have put additional stress on the aircraft's landing gear and brakes.
Furthermore, the runway touchdown position was misaligned by 28 feet from the centreline, indicating a minor deviation from the required alignment during landing. Local weather conditions were favorable, with a temperature of 72 degrees Fahrenheit, which would not have had any significant impact on the landing.
The total landing distance was 7,894 feet, which accounted for 75% of the runway. Although runway length was 10,560 feet, this still leaves limited room for unexpected issues to arise. Furthermore, the runway rollout alignment was also slightly misaligned by 39 feet from the centreline, which is another minor deviation that could potentially cause problems in future landings.
In summary, while the landing was largely successful, there were several areas of concern, such as the high threshold height and speed, heavy touchdown rate, and minor deviations from the required alignment during landing. These issues highlight the importance of strict adherence to standard approach procedures and landing techniques to ensure safe and efficient landings.
