Use smaller, smoother aileron inputs to hold the climb bank angle near wings-level.

What happened: During Climb 3 the bank angle averaged 1.8°, well beyond a steady wings-level climb.

Watch for: Attitude indicator - bank angle, keeping it close to wings-level through the climb.

See Departure Climb 3

Twenty knots on a monitor produces the visual sensation of about ten. The advice to "taxi at a walking pace" cannot fix this, because your sense of walking pace is exactly the thing that's broken. Put the groundspeed readout in your scan and obey it for the next fifty flights, the way a student pilot leans on the airspeed indicator before learning to read attitude.

The enroute level cruise began 47 miles southeast of Matinicus Island Airport in Maine, and lasted for 111 minutes, covering a distance of 954 nautical miles. The aircraft then underwent another enroute climb, this time from 31,154 feet to 33,142 feet, an increase of 1,988 feet in 3 minutes, covering a distance of 30 nautical miles. The level cruise resumed at a new location, lasting for 241 minutes and covering 2,117 nautical miles.

The aircraft continued its journey, undergoing another enroute climb from 33,110 feet to 35,111 feet, an increase of 2,000 feet in 3 minutes, covering a distance of 31 nautical miles. The level cruise started 58 miles north of Ferreries, Spain, and lasted for 115 minutes, covering a distance of 989 nautical miles. Another enroute climb took place 19 miles northeast of Ajdabiya, Libya, where the aircraft ascended from 35,490 feet to 36,905 feet, an increase of 1,414 feet in 2 minutes, covering a distance of 14 nautical miles.

The enroute level cruise resumed 25 miles east of Ajdabiya, lasting for 202 minutes and covering 1,595 nautical miles. As the aircraft approached its destination, it began its descent from 36,511 feet to 8,959 feet, a decrease of 27,553 feet in 16 minutes, covering a distance of 62 nautical miles.

The final approach to runway 25L at Addis Ababa Bole International Airport (HAAB) was made from the east, heading 254.0° at 4 nautical miles and 1,327 feet above ground level. The landing took place on runway 25L, which was 3,077 meters long. The threshold height was good, and the threshold speed was slightly below the target at 119 knots. The touchdown distance was good at 333 meters, and the touchdown speed was 113 knots, which was also good.

However, the touchdown rate was hard at -400 feet per minute. The runway touchdown position was slightly misaligned by 4.6 meters from the centerline. The local weather conditions at the time of landing were 13°C temperature and a wind speed of 2 knots at 290°, with a crosswind of 1 knot and a headwind of 1 knot.

The total landing distance was 1,180 meters, which was 38% of the runway length. The runway rollout alignment was very good.

Landing on runway 25L at HAAB Addis Ababa Bole International Airport in the Boeing 777-300ER
Landing Score 96.84 %
Landing Summary

The Boeing 777-300 aircraft successfully landed at Addis Ababa Bole International Airport, achieving a high score of 96.8%. The final approach to runway 25L was initiated from the east, with the aircraft heading 254.0° at a distance of 4 nautical miles and an altitude of 1,327 feet above ground level.

Upon landing, the aircraft touched down on the runway with a speed of 113 knots, which was within the acceptable range. The touchdown distance of 333 meters was also satisfactory, indicating a smooth and controlled descent. However, the touchdown rate was slightly harder than expected, at -400 feet per minute, which may require further attention to optimize the landing technique.

The runway touchdown position was slightly misaligned from the centerline by 4.6 meters, which may be attributed to factors such as wind or pilot error. The local weather conditions at the time of landing were relatively calm, with a temperature of 13°C and a gentle wind of 2 knots from 290°. The crosswind and headwind components were minimal, at 1 knot each, which suggests that the wind did not significantly impact the landing.

The total landing distance of 1,180 meters was 38% of the runway length, which is a reasonable figure considering the aircraft's size and weight. The runway rollout alignment was excellent, indicating that the pilot maintained control and stability during the landing roll. Overall, the landing was successful, and the aircraft came to a stop within a safe distance from the runway threshold.
