Maintain the centreline
A small uncorrected heading error at 40 knots becomes a metre of offset per second by 100 knots, noticed only at rotation, producing a crabbed liftoff. Root cause is nearly always eyes on the tape instead of the far end of the runway. Small heading changes displace a distant point visibly long before the nearby centreline stripes look wrong.

The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
One stabilised approach gate: five checks where the approach path is 500 ft above the runway. The 1,000 ft gate was not assessed, because the approach did not join final that far out.
Side view — the last 1,800 m of the approach.
Plan view — the first 1,800 m of the 3,006 m runway, to the same scale as the side view.
The 472 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The flight began with a taxiing period from the parking to the runway, which took 4 minutes and covered less than 1 nautical mile. The aircraft, a Boeing 777-300, then departed from runway 23 at FNLU Quatro de Fevereiro International Airport in Luanda, Angola. The takeoff distance was 1,014 meters, which accounted for 28% of the runway. The liftoff speed was 169 knots, and the local weather conditions were characterized by a temperature of 31°C, a wind speed of 6 knots at 210°, with a crosswind of 2 knots and a headwind of 5 knots.
As the aircraft climbed out of the airport, it began its enroute climb 1 mile southwest of FNLU Quatro de Fevereiro International Airport. The climb took 18 minutes and covered 129 nautical miles, during which the aircraft ascended from 1,258 feet above sea level to 37,869 feet above sea level, an increase of 36,611 feet. The enroute level cruise started 53 miles west of N'zeto, Angola, and lasted for 138 minutes, covering 1,087 nautical miles.
The enroute descent began 28 miles southeast of Axim, Ghana, and took 22 minutes to descend from 37,898 feet above sea level to 1,287 feet above sea level, a decrease of 36,610 feet. The descent covered 123 nautical miles. The final approach to runway 21 at DIAP Félix-Houphouët-Boigny International Airport was made from the north, heading 202.0° at 4 nautical miles and 1,261 feet above ground level.
The landing on runway 21 was successful, with a touchdown point 60 meters beyond the touchdown zone. The touchdown speed was a little fast at 140 knots, but the touchdown rate was fair at -207 feet per minute. The runway touchdown alignment was perfect, and the local weather conditions were characterized by a temperature of 28°C, a wind speed of 3 knots at 210°, with a crosswind of 0 knots and a headwind of 3 knots. The total landing distance was 1,724 meters, which accounted for 57% of the runway. The runway rollout alignment was very good.
The taxiing period from the runway to the parking took 1 minute and covered less than 1 nautical mile. The total flight distance was 1,347 nautical miles, and the flight duration was 185 minutes. The aircraft used 21,755 kilograms of fuel during the flight.
The Boeing 777-300 aircraft successfully landed at DIAP Félix-Houphouët-Boigny International Airport, achieving a high score of 99.7%. The final approach to runway 21 was conducted from the north, with the aircraft heading 202.0° at a distance of 4 nautical miles and an altitude of 1,261 feet above ground level.
The landing was executed with good threshold height, and the threshold speed of 145 knots was also satisfactory. However, the touchdown speed of 140 knots was slightly faster than ideal, which may have contributed to a slightly higher touchdown rate of -207 feet per minute. Despite this, the runway touchdown alignment was perfect, indicating that the aircraft was well-aligned with the runway during touchdown.
The local weather conditions at the time of landing were favorable, with a temperature of 28°C and a gentle headwind of 3 knots from a direction of 210°. The crosswind component was negligible, with a speed of 0 knots. The total landing distance of 1,724 meters was 57% of the runway length, which is a relatively short distance considering the aircraft's size and weight.
The runway rollout alignment was also very good, indicating that the aircraft's brakes were applied smoothly and effectively, allowing the aircraft to come to a stop in a straight line. Overall, the landing was a success, with the aircraft touching down safely and coming to a stop within a short distance of the runway threshold.
