Shorten the long landing
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.

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 152 m above the runway. The 305 m gate was not assessed, because the approach did not join final that far out.
Side view — the last 2,630 m of the approach.
Plan view — the first 2,630 m of the 3,602 m runway, to the same scale as the side view.
Touched down 1,506 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The flight began with a taxiing period from the parking area to the runway, which took 12 minutes and covered a distance of 2 nautical miles. The aircraft, an Embraer E175, then departed from runway 28 at LIME Milan Bergamo Airport / Antonio Locatelli Air Base. The takeoff distance was 1,515 meters, which is 60% of the runway length. The liftoff speed was 143 knots.
The local weather conditions at the time of departure were characterized by a temperature of 4 degrees Celsius and a wind speed of 0 knots at 0 degrees. The aircraft then began its enroute climb, starting overhead Orio al Serio in Lombardia, Italy. The climb took 11 minutes and covered a distance of 9 nautical miles, with the aircraft ascending from 535 meters above sea level to 5,431 meters above sea level, an increase of 4,895.5 meters.
After reaching the cruising altitude, the aircraft entered a level cruise phase, which lasted 74 minutes and covered a distance of 282 nautical miles. The cruise phase started overhead Credaro in Lombardia, Italy. The aircraft then began its enroute descent, starting overhead Edlitz in Niederoesterreich, Austria. The descent took 7 minutes and covered a distance of 20 nautical miles, with the aircraft descending from 5,486 meters above sea level to 1,129 meters above sea level, a decrease of 4,356.8 meters.
The aircraft then began another climb phase, starting overhead LHFP Piuszpuszta Airfield Fertőrákos in Gyor-Moson-Sopron megye, Hungary. The climb took 2 minutes and covered a distance of 7 nautical miles, with the aircraft ascending from 1,142 meters above sea level to 1,373 meters above sea level, an increase of 230.6 meters.
The aircraft then entered another level cruise phase, which lasted 4 minutes and covered a distance of 13 nautical miles. This phase started 4 miles south east of Fertorakos in Gyor-Moson-Sopron megye, Hungary. The aircraft then began its final descent, starting 1 mile north east of Donnerskirchen in Burgenland, Austria. The descent took 3 minutes and covered a distance of 8 nautical miles, with the aircraft descending from 1,369 meters above sea level to 599 meters above sea level, a decrease of 769.6 meters.
The final approach to runway 34 at LOWW Vienna International Airport was made from the south, with the aircraft heading 344.0 degrees at 4 nautical miles and 416.1 meters above ground level. The landing was made on runway 34, which has a length of 3,602 meters. The threshold height was good, but the threshold speed was too high at 137 knots. The touchdown point was 1,081 meters beyond the touchdown zone, and the touchdown speed was excessively fast at 136 knots. The touchdown rate was firm at -1.6 meters per second.
The runway touchdown position was misaligned by 10.2 meters from the centreline, and the runway rollout alignment was misaligned by 15.4 meters from the centreline. The total landing distance was 2,541 meters, which is 71% of the runway length. The local weather conditions at the time of landing were characterized by a temperature of 1 degree Celsius and a wind speed of 0 knots at 0 degrees.
The total flight distance was 347 nautical miles, and the flight duration was 103 minutes. The aircraft used 3,128 kilograms of fuel during the flight.
The aircraft in question, an Embraer E175, successfully landed at Vienna International Airport (LOWW) on runway 34. The final approach was initiated from the south, heading 344.0° at an altitude of 416.1 meters above ground level (agl) and a distance of 4 nautical miles from the runway. The aircraft touched down on the runway, but unfortunately, it did not meet the desired standards.
One of the primary concerns was the threshold speed, which was recorded at 137 knots, exceeding the recommended threshold speed. This could have contributed to the aircraft's touchdown point being 1,081 meters beyond the designated touchdown zone. Furthermore, the touchdown speed of 136 knots was also considered excessively fast, resulting in a firm touchdown rate of -1.6 meters per second. This could have put additional stress on the aircraft's landing gear and potentially compromised the safety of the passengers and crew.
In addition to the speed-related issues, the aircraft's runway touchdown position was misaligned by 10.2 meters from the centerline, indicating a slight deviation from the intended path. This misalignment was also observed during the runway rollout, where the aircraft was off-centerline by 15.4 meters. These deviations could be attributed to factors such as pilot error, aircraft performance, or wind conditions.
The local weather conditions at the time of the landing were relatively calm, with a temperature of 1°C and no wind. This suggests that wind was not a contributing factor to the deviations observed during the landing. However, it is essential to note that the absence of wind does not necessarily mean that the landing was perfect, and there may be other factors at play.
Overall, the landing of the Embraer E175 at Vienna International Airport (LOWW) on runway 34 was not without its issues. The aircraft's threshold speed, touchdown speed, and runway touchdown position were all outside the recommended parameters, resulting in a less-than-ideal landing. The total landing distance of 2,541 meters, which accounted for 71% of the runway, was also slightly higher than expected.
