Flight Score
Arrival
Reduce power earlier on final to bleed speed back to 139 kt before crossing the threshold.
What happened: You crossed the threshold at 148 kt, 9 kt above the 139 kt target.
Watch for: Airspeed, targeting 139 kt at the threshold.
See Arrival 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.
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 5,000 ft of the approach.
Plan view — the first 5,000 ft of the 7,000 ft runway, to the same scale as the side view.
The 1,639 ft touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The aircraft taxied from the parking area to runway 28R at KORD Chicago O'Hare International Airport in 18 minutes, covering 3 nm.
During the departure roll on runway 28R, the Boeing 737-800 accelerated over a takeoff distance of 5,729 ft (44 % of runway) and lifted off at 167 kt. Local weather reported a temperature of 77 °F, wind 8 kt from 220 °, with a 6 kt crosswind component and a 5 kt headwind.
The initial climb began overhead KORD, climbing from 1,632 ft asl to 35,987 ft asl, an increase of 34,355 ft in 18 minutes while covering 123 nm.
The first cruise segment started 2 mi north-east of 6IS8 Trisler Airport and lasted 11 minutes, during which the aircraft flew 81 nm.
A second climb commenced 3 mi north-west of KAJG Mount Carmel Municipal Airport, rising from 36,205 ft asl to 37,599 ft asl, a gain of 1,394 ft in 2 minutes and covering 13 nm.
The subsequent cruise phase began 1 mi south-west of Mount Carmel, lasting 45 minutes and extending 351 nm.
The first descent started 11 mi north-west of Autaugaville, descending from 37,999 ft asl to 9,001 ft asl, a loss of 28,998 ft in 18 minutes while traversing 118 nm.
A brief cruise followed 3 mi east of FL34 Eglin Test Site B6 Airport, lasting 2 minutes and covering 7 nm.
The second descent began 3 mi north-west of Wright, dropping from 8,992 ft asl to 3,423 ft asl, a decrease of 5,570 ft in 7 minutes over 32 nm.
Another short cruise segment started 2 mi east of 93FD Chumuckla 20-20 Airport, lasting 2 minutes and covering 5 nm.
The final descent originated 1 mi west of 16FL J-22 Ranch Airport, descending from 3,048 ft asl to 1,384 ft asl, a loss of 1,664 ft in 4 minutes and covering 11 nm.
For the final approach to runway 17 at KPNS Pensacola International Airport, the aircraft approached from the north on a heading of 167.0°, at 4 nm and 1,247 ft agl.
Landing on runway 17 was executed with a threshold speed of 148 kt; touchdown occurred 297 ft beyond the touchdown zone at 143 kt, with a touchdown rate of minus 205 fpm. Local conditions were 76 °F, wind 5 kt from 354 °, a 1 kt crosswind and a 5 kt tailwind. The total landing distance was 4,662 ft (67 % of runway) and runway rollout alignment was perfect.
The rollout phase confirmed the aircraft remained aligned with the runway centreline throughout deceleration.
After exiting the runway, the aircraft taxied to the parking area in 5 minutes, covering less than 1 nm.
In total, the flight covered 753 nm, lasted 130 minutes, and consumed 10,613 lb of fuel.
The Boeing 737-800 established a final approach to runway 14 at KSRQ Sarasota Bradenton International Airport from the north-west, tracking a heading of 134.0° at 4 nm and 1,377 ft agl. Local weather was 75 °F with wind 4 kt from 120°, a 1 kt crosswind component and a 3 kt headwind component.
Threshold height was good and the threshold speed was slightly above target at 139 kt.
Touchdown occurred 1,306 ft down the runway, a good distance, with a touchdown speed of 133 kt that was a little fast. The touchdown rate was fair at minus 244 fpm and runway touchdown alignment was perfect.
Total landing distance measured 4,337 ft, representing 53 % of the runway length, and rollout alignment was perfect.
With a final score of 99.7 %, the landing was excellent; refining the approach to bring the threshold speed to the target and moderating the touchdown speed and rate will further tighten performance.
