Keep the approach speed on target
Every knot above Vref is stored kinetic energy, and energy stored at the threshold must be dissipated in ground effect before the aeroplane will stop flying. Because kinetic energy scales with the square of speed, the excess you must dissipate grows fast. At a 45-knot approach, five knots hot is over a tenth more speed and roughly a quarter more energy to get rid of in ground effect. This is why the fix is never in the flare. It was decided three miles earlier, on final, at the airspeed indicator.

Two stabilised approach gates, each with six checks at 1,000 ft and 500 ft above the runway.
The approach, gate by gate
Side view — the last 1,524 m of the approach.
Plan view — the first 1,524 m of the 3,807 m runway, to the same scale as the side view.
The 390 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
A Boeing 737 was involved in a comprehensive flight operation, commencing with a taxiing process from the parking spot to the runway that lasted 5 minutes and covered a distance of 4 nautical miles (nm) at Siegerland Airport. The departure roll took place from runway 13, and the aircraft successfully took off, utilizing 1,328 meters out of 1,600 meters of the runway for takeoff, with a liftoff speed of 142 knots (kt).
With the runway departure complete, the aircraft initiated an enroute climb, rising from an elevation of 2,919 feet above sea level (asl) to 9,733 ft asl, an astonishing increase of 6,813 feet in just 2 minutes. This climb segment covered a distance of 10 nm, and it took place southeast of Liebenscheid in Germany. Following this, the aircraft entered a level cruise phase above Leun in Hessen, Germany, where it remained stationary in altitude for 6 minutes, covering 6 nm.
After this brief respite, the plane embarked on the second major enroute climb phase, from 10,183 ft asl to 16,348 ft asl, a vertical distance of 6,165 feet. This climb, taking place south of Weilburg in Hessen, Germany, occurred in merely 3 minutes and spanned a distance of 20 nm.
Following this enroute climb segment, the aircraft entered another phase of level cruise, this time above Daaden in Rheinland-Pfalz, Germany. This prolonged level cruise, lasting 11 minutes and covering an impressive 34 nm, allowed the aircraft to conserve fuel.
However, the aircraft eventually initiated a descent from 16,331 ft asl to 15,293 ft asl, a decrease of 1,038 feet, in a mere 2 minutes and 10 nm southeast of Halver in Nordrhein-Westfalen, Germany.
The descent continued in short hops, with the aircraft entering another level cruise segment above Wermelskirchen in Nordrhein-Westfalen, Germany, lasting 5 minutes and covering 21 nm. Following this, a descent from 15,295 ft asl to 6,990 ft asl, a descent of 8,305 feet in merely 3 minutes and 10 nm north of Hennef in Nordrhein-Westfalen, Germany, took place.
Subsequent enroute descent segments brought the aircraft closer to its destination, with a 2-minute descent from 6,990 ft asl to 6,058 ft asl, covering 5 nm east of Alfter in Nordrhein-Westfalen, Germany. The final short enroute cruise segment occurred 2 miles southeast of Bruehl in Nordrhein-Westfalen, Germany, lasting 6 minutes and covering 14 nm.
The final descent began, and the aircraft descended from 6,131 ft asl to 1,981 ft asl, a decrease of 4,150 feet, within 2 minutes and 10 nm west of Leverkusen in Nordrhein-Westfalen, Germany.
With this series of climbs, descents, and level cruise phases, the aircraft successfully navigated its way into the vicinity of Cologne Bonn Airport. The final approach was initiated at an altitude of 1,694 feet above ground level (agl), heading 138.0° and at a distance of 2 nm from the runway. Landing occurred on runway 13L at Cologne Bonn Airport, which measures 3,807 meters in length.
Interestingly, the aircraft landed at an excessively high speed of 209 kt and an excessively fast speed of 204 kt. While the touchdown rate was considered fair at -250 feet per minute (fpm), the runway touchdown position deviated by 19.9 meters
Landing Assessment Report
The Boeing 737 aircraft successfully landed at Cologne Bonn Airport's runway 13L with a final score of 82.5%. The aircraft was approaching the runway from the northwest, heading 138.0° at an altitude of 1,694 feet above ground level (agl) and 2 nautical miles (nm) from the threshold.
Upon evaluation, it was found that the threshold height was good, indicating a satisfactory approach path with sufficient altitude before touching down on the runway. However, the threshold speed was excessively high at 209 knots, which may indicate a potential concern for the aircraft's ability to maintain control before touchdown. Furthermore, the touchdown speed of 204 kt was also excessively fast, highlighting the need for better control and maneuvering skills during the final stages of the approach.
The touchdown rate was found to be fair at -250 feet per minute (fpm), suggesting some degree of control and stability during the touchdown. Nevertheless, the touchdown point was located 150 meters beyond the designated touchdown zone, indicating a possible deviation from the intended landing spot.
Additionally, the runway touchdown position was significantly misaligned by 19.9 meters from the centerline, potentially increasing the risk of veering off the runway or experiencing reduced braking performance. This misalignment could be due to a range of factors, including wind shear or improper control during the final stages of the approach.
The local weather conditions at the time of landing were favorable, with a temperature of 22°C and a wind speed of 3 knots at 143°. With a slight headwind of 3 kt, this had little impact on the aircraft's descent and landing speed. The resulting total landing distance was 1,333 meters, which is within 35% of the runway's length. Although this is relatively short, it may indicate the need for further improvement in the pilot's ability to control the aircraft's descent and touchdown speed.
In the post-landing phase, it was observed that the runway rollout alignment was only slightly misaligned by 14.8 meters from the centerline, suggesting a decent attempt to maintain directional control during taxiing and rollout.
In summary, while the landing attempt was generally successful, there are areas of concern that require attention, such as excessive threshold and touchdown speeds, a misaligned touchdown position, and an overall score of 82.5%. To further improve, pilots should focus on optimizing control during the final stages of the approach, reducing the risk of misaligned touchdowns, and enhancing their overall landing performance.
