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 1,524 m of the approach.
Plan view — the first 1,524 m of the 3,397 m runway, to the same scale as the side view.
The 239 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 17 minutes and covered a distance of 2 nautical miles. The aircraft, a Cessna CJ4 Citation, then departed from runway 05 at VOCB Coimbatore International Airport. The takeoff distance was 466 meters, which accounted for 16% of the runway. The liftoff speed was 111 knots.
The local weather conditions at the time of departure were characterized by a temperature of 32 degrees Celsius and a wind speed of 6 knots at 210 degrees. This resulted in a crosswind of 2 knots and a tailwind of 6 knots. The aircraft then began its enroute climb, starting 1 mile north of Irugur, and climbed from an altitude of 2,285 feet above sea level to 12,415 feet above sea level, an increase of 10,130 feet, in just 3 minutes and covering a distance of 12 nautical miles.
The enroute climb was followed by a series of level cruises and descents. The first descent started 3 miles south of Madukkarai and descended from 12,413 feet to 10,086 feet, a decrease of 2,328 feet, in 2 minutes and covering 9 nautical miles. The aircraft then entered a level cruise, lasting 2 minutes and covering less than 1 nautical mile, before beginning another descent from 10,086 feet to 8,386 feet, a decrease of 1,699 feet, in 2 minutes and covering 10 nautical miles.
The aircraft then entered another level cruise, lasting 2 minutes and covering 8 nautical miles, before beginning its final descent from 8,387 feet to 1,626 feet, a decrease of 6,761 feet, in 6 minutes and covering 23 nautical miles. The final approach to runway 27 at VOCI Cochin International Airport was made from the east, heading 283.0 degrees at 4 nautical miles and 1,600 feet above ground level.
However, the aircraft was required to perform a go-around at 173 feet above ground level. The aircraft then landed on runway 27, with a runway length of 3,397 meters. The threshold height was good, but the threshold speed was slightly below the target at 96 knots. The touchdown distance was good at 236 meters, and the touchdown speed was 86 knots, which was good. However, the touchdown rate was fair at -242 feet per minute.
The runway touchdown position was misaligned by 12.1 meters from the centreline, and the runway rollout alignment was slightly misaligned by 10.4 meters from the centreline. The local weather conditions at the time of landing were characterized by a temperature of 31 degrees Celsius and a wind speed of 9 knots at 300 degrees, resulting in a crosswind of 5 knots and a headwind of 8 knots.
The total landing distance was 1,341 meters, which accounted for 39% of the runway. The taxiing period from the runway to the parking took 2 minutes and covered less than 1 nautical mile. The total flight distance was 78 nautical miles, and the flight duration was 41 minutes. The aircraft used 778 kilograms of fuel during the flight.
The Cessna CJ4 Citation aircraft successfully landed at VOCI Cochin International Airport, achieving a score of 94.7%. The final approach to runway 27 was initiated from the east, with a heading of 283.0° at a distance of 4 nautical miles and an altitude of 1,600 feet above ground level.
Upon landing, the aircraft touched down on the runway with a speed of 96 knots, which was slightly below the target threshold speed. The touchdown distance of 236 meters was considered good, indicating a smooth and controlled descent. The touchdown speed of 86 knots was also within acceptable limits, further emphasizing the pilot's skill in managing the aircraft's speed during the landing.
However, there were some areas for improvement. The touchdown rate of -242 feet per minute was only fair, suggesting that the pilot could have maintained a more gradual descent to reduce the impact on the aircraft's landing gear. Additionally, the runway touchdown position was misaligned by 12.1 meters from the centreline, which may have been due to a slight deviation in the pilot's approach path.
The local weather conditions at the time of landing were characterized by a temperature of 31°C and a wind speed of 9 knots from a direction of 300°. The crosswind component was 5 knots, while the headwind component was 8 knots. These conditions were relatively favorable for the landing, with the headwind component helping to stabilize the aircraft's approach path.
The total landing distance of 1,341 meters was 39% of the runway length, which is a reasonable distance considering the aircraft's size and weight. However, the runway rollout alignment was slightly misaligned by 10.4 meters from the centreline, which may have been due to a slight deviation in the pilot's control inputs during the rollout phase.
Overall, the landing was considered successful, with the pilot demonstrating good control and management of the aircraft throughout the approach and landing phases. However, there were some areas for improvement, particularly in terms of maintaining a more gradual descent and aligning the aircraft with the centreline during the rollout phase.
