Settle the descent rate
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. They are the approach's score: the checks passed out of the checks that ran.
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 961 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 21 at KGCN Grand Canyon National Park Airport in a period of 5 minutes, covering less than 1 nm.
During the departure roll on runway 21 the aircraft used a takeoff distance of 545 m, representing 20 % of the runway, and lifted off at 96 kt; ambient conditions were 29 °C with wind 23 kt at 260 °, a cross-wind component of 15 kt and a head-wind component of 18 kt.
The initial climb began overhead KGCN, climbing from 6,946 ft asl to 8,280 ft asl, an increase of 1,334 ft in 1 minutes while covering 5 nm.
A subsequent climb commenced 3 miles north-east of Grand Canyon, rising from 5,681 ft asl to 7,848 ft asl, an increase of 2,167 ft in 3 minutes and covering 12 nm.
The aircraft then entered a level cruise segment that started 7 miles north of Grand Canyon, lasting 2 minutes and covering 5 nm.
A later climb started 2 miles north of Grand Canyon, climbing from 7,521 ft asl to 7,383 ft asl, an increase of 138 ft in 3 minutes while covering 8 nm.
Descent began 1 mile north of Tusayan, descending from 8,284 ft asl to 5,993 ft asl, a decrease of 2,291 ft in 2 minutes and covering 6 nm.
The final approach to runway 21 was flown from the north-east on a heading of 221.0 ° at 1 nm and 816 ft agl, followed by a descent from 1,583 ft agl to -21 ft agl in 59 seconds; the approach was scored on the stabilisation gates.
Landing on runway 21 occurred with a runway length of 2,743 m; the threshold height at 89 ft agl and the threshold speed of 102 kt were both significantly above target. Touchdown was recorded 539 m beyond the touchdown zone at a speed of 82 kt, with a touchdown rate of minus 159 fpm and a lateral deviation of 9.2 m from the centreline. Weather at the time was 28 °C with wind 17 kt at 260 °, a cross-wind of 11 kt and a head-wind of 13 kt. Total landing distance measured 1,279 m, representing 47 % of the runway.
Runway rollout alignment was slightly misaligned by 9.0 m from the centreline.
The aircraft taxied from the runway to the parking area in 3 minutes, covering less than 1 nm.
In total the flight covered 42 nm, lasted 17 minutes and consumed 78 kg of fuel.
The North American Rockwell OV-10 Bronco approached runway 21 at KGCN Grand Canyon National Park Airport from the north east, tracking a heading of 221.0° at 1 nm and 816 ft agl. At the 1,000 ft gate the approach was assessed as unstable, with sink rate too high and off the glideslope. The final descent proceeded from 1,583 ft agl to -21 ft agl in 59 seconds.
The threshold height of 89 ft agl was significantly above the target, and the threshold speed of 102 kt was well above the target.
Touchdown occurred 539 m beyond the designated touchdown zone, with a speed of 82 kt that met the good rating and a vertical rate of minus 159 fpm also rated good. The aircraft touched down 9.2 m off the centreline, and the total landing distance was 1,279 m, representing 47 % of the 2,743 m runway.
During rollout the aircraft remained slightly misaligned, drifting 9.0 m from the centreline, while ambient conditions were 28 °C temperature, wind 17 kt from 260°, including an 11 kt crosswind component and a 13 kt headwind.
Reduce the approach descent rate to achieve the intended threshold height and bring the threshold speed closer to target values. Aim to arrest the aircraft within the touchdown zone to limit the 539 m overshoot and maintain centreline alignment through flare and rollout.
