Preparing for a stable approach will give you time to decide on whether to attempt the landing or going around. Too much altitude with a high sink rate will result in carrying too much speed onto the runway. Configuring flaps and the gear late also won't help the speed decay.

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 2,743 m runway, to the same scale as the side view.
Touched down 984 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The aircraft taxied from the parking area to runway 19 at KSGU St George Regional Airport, a movement that required 18 minutes and covered 4 nm.
During the departure roll on runway 19, the OV-10 Bronco accelerated over a takeoff distance of 662 m, representing 23 % of the runway, and lifted off at 105 kt; ambient temperature was 23 °C with a wind of 5 kt from 120°, including a 5 kt cross-wind component and a 1 kt head-wind.
The first en-route climb began 1 mile south of KSGU, climbing from 3,683 ft asl to 12,634 ft asl, an altitude gain of 8,952 ft achieved in 4 minutes while traversing 13 nm.
A level cruise segment commenced 7 miles south of UT47 Grassy Meadows/Sky Ranch Landowners Assn Airport, lasting 2 minutes and covering 6 nm.
The second climb started 6 miles west of KAZC Colorado City Municipal Airport, rising from 12,779 ft asl to 13,559 ft asl, a gain of 780 ft in 2 minutes over a distance of 6 nm.
A subsequent cruise phase began 2 miles southwest of Centennial Park, persisted for 2 minutes and spanned 7 nm.
The third climb was initiated 4 miles south of Cane Beds, increasing altitude from 13,738 ft asl to 17,155 ft asl, a climb of 3,417 ft completed in 8 minutes across 34 nm.
Following that, a cruise segment started 15 miles west of KGRM Devil’s Track Airport, lasted 2 minutes and covered 6 nm.
The fourth climb began 11 miles west of KGRM Devil’s Track Airport, climbing from 17,080 ft asl to 18,392 ft asl, an ascent of 1,313 ft in 2 minutes while traveling 6 nm.
A descent segment commenced 8 miles southwest of KGRM Devil’s Track Airport, descending from 18,408 ft asl to 5,072 ft asl, a loss of 13,336 ft in 3 minutes and covering 14 nm.
The aircraft then performed a climb 7 miles northeast of the Grand Canyon, rising from 5,080 ft asl to 8,126 ft asl, an increase of 3,045 ft over 4 minutes and 12 nm.
On final approach to runway 21 at KGCN Grand Canyon National Park Airport, the aircraft approached from the northeast on a heading of 222.0° at 1 nm and 1,535 ft agl.
Landing on runway 21, whose length is 2,743 m, the threshold speed was recorded at 116 kt; touchdown occurred 201 m beyond the touchdown zone at a speed of 93 kt, with a touchdown rate of minus 270 fpm and a lateral deviation of 13.8 m from the centreline. Local temperature was 22 °C, and the total landing distance measured 1,023 m, equivalent to 37 % of the runway.
Rollout alignment was noted as slightly off centreline by 13.2 m as the aircraft decelerated after touchdown.
The aircraft taxied from the runway to the parking area in 1 minute, covering less than 1 nm.
In total, the flight covered 112 nm, lasted 35 minutes, and consumed 181 kg of fuel.
The North American Rockwell OV-10 Bronco entered final approach to runway 21 at KGCN Grand Canyon National Park Airport from the north-east on a heading of 222.0° at 1 nm and 1,535 ft agl. At the 1,000 ft gate the approach was assessed as unstable: flaps were not set, sink rate was too high, the aircraft was off the glideslope and more than 20 kt above VREF.
At threshold the height was good, but the threshold speed was too high at 116 kt.
Touchdown occurred 201 m beyond the touchdown zone with a speed of 93 kt, described as a little fast, and a touchdown rate of minus 270 fpm, rated fair. The runway touchdown position was misaligned by 13.8 m from the centreline.
The aircraft rolled out over a total landing distance of 1,023 m, representing 37 % of the 2,743 m runway, and the rollout alignment was slightly misaligned by 13.2 m from the centreline.
To improve the score, focus on establishing a stabilized approach by setting flaps and controlling speed to remain within VREF limits, and work on centreline alignment during flare to reduce the touchdown and rollout deviations.
