The flight in question was a demonstration of the Vision Jet's capabilities, and it began with a go-around on runway 06 at LFHU Altiport L'Alpe d'Huez - Henri GIRAUD, a small airfield located in the mountains.
As the aircraft approached the runway, it was noted that the final approach was made from the south west, heading at 62.0° at a distance of 0 nm and an altitude of 0 ft above ground level (agl). The good threshold height allowed for a safe landing. However, the threshold speed was significantly higher than the target value of 76 kt, which may indicate that the pilot was holding back on the throttle in anticipation of touch down speed.
Upon touchdown, the Vision Jet had a distance of 63 m, which was good according to the assessment. Moreover, the speed at which the aircraft touched down was a little fast at 74 kt. The aircraft's descent rate, however, was perfectly controlled at 152 fpm.
Another point worth mentioning was that the runway touchdown position was off-centreline by 9.9 m from the centreline of the runway. Given the conditions at the time of the flight – the local temperature was 17 °C, with wind blowing at 11 kt at 189°, and moderate crosswind and tailwind of 9 kt and 7 kt respectively – this slight deviation is understandable. The combined effect of the wind on the aircraft would have had an impact on the landing alignment.
After touching down, the Vision Jet taxied down the runway for a distance of 283 m, which translates to about 66% of its total length. Unfortunately, the aircraft's centreline alignment during the rollout phase was off by 16.5 m from the centreline. It was apparent that the aircraft's handling on the runway may not have been entirely satisfactory, possibly due to the strong wind conditions during touch down.
The Vision Jet flight had a total distance of 131 nm, taking approximately 45 minutes to complete. The fuel consumption during the entire flight was 196 kg.

The Vision Jet has successfully landed on runway 06 at LFHU Altiport L'Alpe d'Huez - Henri GIRAUD after initiating its final approach from the south-west. At a heading of 62.0°, the aircraft had just begun its descent from an altitude of 0 ft at a ground distance of 0 nm from the runway threshold.
This challenging approach was made more complicated by the local weather conditions, with a temperature of 17 °C and winds blowing at 11 kt from a direction of 189°. Given this situation, a crosswind of 9 kt would have required some skill and precision to navigate. The flight crew was also experiencing a moderate tailwind of 7 kt, which would've necessitated careful attention to the aircraft's speed.
As the Vision Jet touched down, it achieved an excellent touchdown rate of 152 fpm, confirming a smooth and controlled descent. However, it was a little above the target speed with an indication of 74 kt at touching down. Considering this data, the crosswind would've had a greater influence on the plane than anticipated and might have added to the overall speed due to the conditions mentioned.
It's observed that the aircraft's touchdown distance was satisfactory at approximately 63 m. Nonetheless, the touchdown position on the runway was slightly off the centreline by around 9.9 m. Following this, the total landing distance, which includes both the rollout and the landing phase, was 283 m, covering 66% of the runway's length.
During the rolling phase, the plane's alignment with the runway centreline was still not ideal by about 16.5 m, indicating there's room for improvement in maintaining alignment once the aircraft has landed and began decelerating. Given the Vision Jet's performance, it is clear that the landing operation at LFHU Altiport L'Alpe d'Huez - Henri GIRAUD presented several challenges, requiring careful handling and control from the flight crew.
