Flight Score
Departure
Use smoother, smaller aileron inputs to keep the wings level and hold bank angle near wings-level during the climb.
What happened: During the climb, bank angle rose to 0.9°, more roll than the climb out called for.
Watch for: Attitude indicator: wings level during the climb
Arrival
Steepen the descent on final to bring the aircraft back down to the glideslope and cross the threshold at 50 ft.
What happened: The approach was flown off the glideslope, and crossing the threshold high like this usually carries the touchdown long.
Watch for: Watch the VASI or PAPI glideslope indication against the threshold crossing height of 50 ft.
Preparing for a stable approach will give you time to decide on whether to attempt the landing or going around. Too much altitude with a high sink rate will result in carrying too much speed onto the runway. Configuring flaps and the gear late also won't help the speed decay.

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. They are the approach's score: the checks passed out of the checks that ran.
At the 1,000 ft gate: sink rate 1,674 fpm, more than the glideslope needed and glideslope 4.9° against the runway's 2.5°.
At the 500 ft gate: sink rate 1,581 fpm, more than the glideslope needed and glideslope 5.7° against the runway's 2.5°.
The approach, gate by gate
Side view — the last 2,030 m of the approach.
Plan view — the first 2,030 m of the 3,268 m runway, to the same scale as the side view.
The 439 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
Departing from Addis Ababa Bole International Airport (HAAB), the Boeing 737-900 initiated its taxiing sequence from the parking area to the runway, a process that took approximately 8 minutes and covered a distance of 2 nautical miles. Upon reaching runway 07R, the aircraft began its departure roll, utilizing 74% of the 2,264-meter runway to achieve liftoff at a speed of 163 knots. The local weather conditions at the time of departure featured a temperature of 23°C, with a wind speed of 14 knots at a direction of 50°, resulting in a 6-knot crosswind and a 13-knot headwind.
As the aircraft climbed away from Addis Ababa, it transitioned into an enroute climb phase, which began approximately 2 miles east of the airport. The climb phase saw the aircraft ascend from an initial altitude of 8,596 feet above sea level to a cruising altitude of 36,559 feet, a vertical increase of 27,963 feet over a distance of 177 nautical miles, achieved in 26 minutes. Following a 33-minute enroute level cruise phase, which covered a distance of 253 nautical miles, the aircraft initiated its enroute descent phase, commencing approximately 9 miles southwest of Hodeidah International Airport (OYHD). The descent phase saw the aircraft descend from 36,547 feet to 9,121 feet, a vertical decrease of 27,427 feet over a distance of 114 nautical miles, achieved in 22 minutes.
Upon reaching the final approach phase, the aircraft began its descent towards runway 36 at Sana'a International Airport (OYSN), approaching from the south at a heading of 359.0°. The aircraft touched down on the runway at a speed of 148 knots, with a touchdown distance of 432 meters, which was within acceptable limits. However, the touchdown rate was slightly higher than desired at -735 feet per minute. Following a successful landing, the aircraft taxied to the parking area, a process that took approximately 2 minutes and covered a distance of less than 1 nautical mile. The total flight distance was 553 nautical miles, achieved in 1 hour and 31 minutes, with a fuel consumption of 4,508 kilograms.
The Boeing 737-900 touched down on runway 36 at OYSN Sana'a International Airport, with a threshold height of 66 ft agl, slightly above the target. The approach quality was satisfactory, with a threshold speed of 154 kt, which was within the acceptable range. The aircraft maintained a steady descent, but the touchdown speed of 148 kt was a little fast, indicating a slight loss of control during the final stages of the approach.
The touchdown characteristics were notable, with a touchdown distance of 432 m, which was within the acceptable range. However, the touchdown rate was very heavy at -735 fpm, suggesting a hard landing. The runway touchdown position was slightly misaligned by 4.4 m from the centreline, which may have been due to a slight deviation in the approach path. The local weather conditions, with a temperature of 18 °C and a wind of 9 kt at 74 °, did not significantly impact the landing.
The total landing distance of 1,954 m, which accounted for 60% of the runway length, was acceptable. The runway rollout alignment was very good, indicating a smooth and controlled deceleration of the aircraft. Overall, the landing performance was satisfactory, with a score of 88.2%. While there were some minor deviations from the ideal, the pilot maintained control throughout the approach and landing phases, resulting in a safe and relatively smooth touchdown.
