Departure Roll

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.

Landing on runway 12 at VTUD Udon Thani Airport in the Cessna Citation CJ4
Landing Score 99.3 %
Landing Summary

The Cessna CJ4 Citation successfully landed at VTUD Udon Thani Airport, achieving a high score of 99.3%. The aircraft approached the runway from the north-west, heading 117.0° at a distance of 4 nautical miles and an altitude of 1,207 feet above ground level (agl). The pilot's final approach was precise, setting the stage for a smooth landing.

Upon touchdown, the aircraft landed on runway 12, which has a length of 3,043 meters. The threshold height was good, indicating that the pilot maintained a safe altitude before touching down. However, the threshold speed was slightly below the target speed of 98 knots, which may have been due to the pilot's cautious approach. Despite this, the touchdown distance of 436 meters was good, and the touchdown speed of 87 knots was also within acceptable limits.

One of the standout aspects of this landing was the excellent touchdown rate of -98 feet per minute (fpm). This indicates that the pilot managed to slow the aircraft down quickly and smoothly, reducing the risk of overrunning the runway. The runway touchdown alignment was also very good, suggesting that the pilot maintained a stable and controlled approach.

The local weather conditions at the time of the landing were favorable, with a temperature of 16°C and a light wind of 1 knot from 26°. There was no significant crosswind or headwind, which made the landing even more challenging. The total landing distance of 1,399 meters was 46% of the runway length, which is a relatively short distance considering the aircraft's size and weight.

Finally, the runway rollout alignment was perfect, indicating that the pilot maintained control of the aircraft during the rollout phase and avoided any deviations from the centerline. Overall, this landing was a testament to the pilot's skill and experience, as well as the aircraft's performance and handling characteristics.
