Departure
Lower the nose and add power to raise climb speed to 161 kt.
What happened: Climb speed was 128 kt against a target of 161 kt, running 33 kt slow through the climb.
Watch for: Airspeed indicator against the climb target of 161 kt.
Arrival
Take the power back earlier on final, so the aircraft settles onto the path and the speed comes back to 94 kt together. Do not push down for the height: that only adds speed.
What happened: You crossed the threshold at 84 ft agl, 34 ft agl above the 50 ft agl target, and at 142 kt, 48 kt over the 94 kt threshold speed. High and fast together is energy the runway has to absorb, and this touchdown came 675 m beyond the aim point.
Watch for: Airspeed indicator: 94 kt on short final, then 50 ft agl over the threshold
Ground effect becomes significant below about one wingspan of height. A Cessna 172, with a 36 ft span, enters ground effect at flare height - the float it feels in the hold-off is ground effect arriving on cue. An A320, with a span around 117 ft, has been in ground effect since before the threshold and there is no sudden cushion to feel, only a gradual reduction in induced drag that lengthens any float you allow.

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 500 ft above the runway. The 1,000 ft gate was not assessed, because the approach did not join final that far out.
Side view — the last 1,524 m of the approach.
Plan view — the first 1,524 m of the 1,812 m runway, to the same scale as the side view.
Touched down 1,132 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, a movement that required 9 minutes and covered 5 nm.
During the departure roll on runway 21, the OV-10 Bronco used a takeoff distance of 541 m, representing 20 % of the runway, and achieved liftoff at 90 kt; ambient temperature was 15 °C.
The initial climb began overhead KGCN, ascending from 7,293 ft asl to 8,400 ft asl, a gain of 1,107 ft in 1 minute while covering 4 nm.
A level cruise segment started 2 mi northwest of Tusayan, lasting 2 minutes and spanning 6 nm.
A subsequent climb commenced 3 mi northeast of Grand Canyon, raising the aircraft from 8,653 ft asl to 9,811 ft asl, an increase of 1,158 ft over 2 minutes and 6 nm.
The first descent began 10 mi northeast of Grand Canyon, descending from 9,816 ft asl to 7,968 ft asl, a loss of 1,848 ft in 3 minutes while covering 14 nm.
A second cruise phase started 11 mi east of KGRM Devil’s Track Airport, lasting 2 minutes and covering 7 nm.
The next climb originated 12 mi southwest of Bitter Springs, climbing from 8,277 ft asl to 11,169 ft asl, a rise of 2,892 ft in 5 minutes across 18 nm.
A further descent began 3 mi south of L41 Marble Canyon, dropping from 11,062 ft asl to 4,331 ft asl, a decrease of 6,731 ft in 4 minutes and covering 16 nm.
On final approach to runway 33 at KPGA Page Municipal Airport, the aircraft descended from 1,227 ft agl to 89 ft agl in 15 seconds and was scored on the stabilisation gates.
Landing on runway 33, whose length is 1,814 m, the threshold height of 84 ft agl was significantly above target and the threshold speed was high at 142 kt. Touchdown occurred beyond the midpoint of the runway, using more than 50 % of the available length, with a touchdown speed of 96 kt and a touchdown rate of minus 41 fpm. The touchdown point was offset 10.3 m from the centreline; local weather reported a temperature of 23 °C, wind 4 kt from 280°, a crosswind component of 4 kt and a headwind component of 1 kt.
The rollout distance measured 1,332 m, representing 73 % of the runway, and the aircraft’s path after touchdown was misaligned by 12.5 m from the centreline.
After landing, the aircraft taxied to the parking area, a movement that took 2 minutes and covered less than 1 nm.
In total, the flight covered 79 nm, required 24 minutes of flight time, and consumed 120 kg of fuel.
The final approach to runway 33 at KPGA was assessed as unstable at the 1,000 ft gate, with flaps not set, a sink rate that was too high, the aircraft off the glideslope and more than 20 kt above VREF; the descent from 1,227 ft agl to 89 ft agl occurred in 15 seconds and the flight was scored on the stabilisation gates.
At threshold the aircraft was at 84 ft agl, a height significantly above the target, and the threshold speed was excessively high at 142 kt.
Touchdown occurred well beyond the intended aim point, using more than 50 % of the available runway; the touchdown speed was fast at 96 kt while the vertical rate was perfect at minus 41 fpm, and the wheel track was misaligned by 10.3 m from the centreline, resulting in a total landing distance of 1,332 m (73 % of the runway).
During rollout the aircraft remained slightly off centreline, with a lateral deviation of 12.5 m.
To improve the score, ensure the correct flap setting and speed control are achieved before the 1,000 ft gate to obtain a stabilized approach, and aim to touch down within the first third of the runway while maintaining centreline alignment.
