Flight Score
Arrival
Keep the back pressure coming once the flare is established, holding the nose up through to touchdown instead of easing it.
What happened: The flare arrested the sink but 598 fpm of it came back before touchdown, and in flights like this one that returning sink usually carries through to a firm or hard touchdown at 457 fpm.
Watch for: Vertical speed indicator: the sink held near zero all the way through touchdown, not allowed to build back up.
There are several things that can go wrong during the flare, carrying too much speed over the threshold, starting the flare at the wrong height and inconsistent flight control inputs, all contribute to a poor flare resulting in a hard touchdown or a float down the runway.

The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
Two stabilised approach gates, each with seven checks, where the approach path is 1,000 ft and 500 ft above the runway. They are the approach's score: the checks passed out of the checks that ran.
The approach, gate by gate
Side view — the last 2,044 m of the approach.
Plan view — the first 2,044 m of the 3,783 m runway, to the same scale as the side view.
Touched down 842 m past the threshold — beyond the full-score zone. The 1.72 G arrival is the firm side of smooth.
The rest of the report
The aircraft taxied from the parking area to the departure runway in 12 minutes, covering a distance of 2 nm before reaching the hold-short line.
During the departure roll on runway 22 at UACC Nursultan Nazarbayev International Airport, the Boeing 737-900 accelerated through a takeoff distance of 1,697 m, representing 49 % of the runway length, and lifted off at 166 kt. Ambient conditions were 6 °C with a wind of 6 kt from 230°, providing a 6 kt headwind and a 1 kt crosswind component.
The climb commenced 1 mile southwest of the departure airport, with the aircraft climbing from 2,186 ft asl to 34,009 ft asl, an altitude gain of 31,823 ft achieved in 21 minutes while covering 146 nm.
The first cruise segment began 38 miles southeast of UAKK Sary-Arka Airport, lasting 49 minutes and extending over 380 nm at a level altitude.
Descent phase one started 21 miles southwest of Chemolgan, during which the aircraft descended from 35,763 ft asl to 9,191 ft asl, a loss of 26,572 ft in 21 minutes while traversing 103 nm.
A brief cruise followed overhead Cholpon-Ata, lasting 2 minutes and covering 4 nm at constant altitude.
The second descent began 3 miles west of UAFG Cholpon-Ata Airport, with a reduction from 8,992 ft asl to 6,687 ft asl, a decrease of 2,305 ft completed in 3 minutes over a distance of 8 nm.
On final approach to runway 25 at UCFL Issyk-Kul, the aircraft approached from the east on a heading of 254.0° at 4 nm and 1,255 ft agl.
Landing was executed on runway 25, which is 3,783 m long; the threshold speed was 153 kt and touchdown occurred 443 m beyond the touchdown zone at a speed of 142 kt. The aircraft touched down with a hard rate of minus 429 fpm, and the alignment was very good. Local weather reported a temperature of 17 °C, wind 2 kt from 340°, a 2 kt crosswind and no headwind. The total landing distance measured 1,981 m, equivalent to 52 % of the runway.
During rollout, the aircraft remained well aligned with the runway centreline, completing the ground run within the measured 1,981 m distance.
The taxi-in from the runway to the parking area required 3 minutes and covered less than 1 nm.
In total, the flight covered 650 nm, lasted 110 minutes, and consumed 5,614 kg of fuel.
The final approach to runway 25 at UCFL Issyk-Kul was flown from the east on a heading of 254.0 ° at 4 nm and 1,255 ft agl. The approach was assessed as stabilised at the 1,000 ft gate, with gear, flaps, sink rate, glideslope and centreline all within limits.
At threshold the aircraft maintained a good threshold height and a threshold speed of 153 kt. The runway length is 3,783 m and the local weather was 17 °C with wind 2 kt from 340 °, giving a crosswind component of 2 kt and no headwind.
Touchdown occurred 443 m beyond the touchdown zone with a touchdown speed of 142 kt, which was judged good. The touchdown rate was hard at minus 429 fpm and runway touchdown alignment was very good.
Rollout used a total landing distance of 1,981 m, representing 52 % of the runway, and rollout alignment was very good.
Refine the flare to reduce the hard touchdown rate and aim for a touchdown point nearer the 300 m (1,000 ft) aim point to further optimise runway usage.
