Flight Score
Departure
Reduce climb power to bring speed back to 185 kt and hold it there.
What happened: Climb speed was 44 kt fast at 229 kt during the climb.
Watch for: Airspeed indicator: 185 kt in the climb
Arrival
Use aileron to level the wings and hold the upwind wing low only enough to track the centreline before touchdown.
What happened: At touchdown the wings were not level, with an average bank angle of 3.6°.
Watch for: Watch the bank angle indicator and keep wings level through touchdown.
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.

The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
One stabilised approach gate: seven 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. These checks are the approach's score.
At the 500 ft gate: no landing flap set, sink rate 2,884 fpm, more than the glideslope needed, glideslope 6.0° against the runway's 3°, wings 10° of bank, against a 10° limit and speed 73 kt FAST on the reference speed of 116 kt.
The approach, gate by gate
Side view — the last 1,524 m of the approach.
Plan view — the first 1,524 m of the 2,621 m runway, to the same scale as the side view.
Touched down 538 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 23L at KTYS McGhee Tyson Airport, a movement that required 2 minutes and covered less than 1 nm.
During the departure roll on runway 23L, the L-39 Albatros accelerated over a takeoff distance of 643 m, representing 25 % of the runway length, and lifted off at 123 kt. Ambient temperature at the time was 28 °C.
Climb commenced approximately 1 mile southwest of KTYS. The aircraft rose from 1,882 ft asl to 34,072 ft asl, an altitude gain of 32,190 ft achieved in 14 minutes while covering 81 nm.
Descent began about 5 miles southwest of 85TN Tellico Plains Muni Madisonville. The flight descended from 34,111 ft asl to 1,769 ft asl, a loss of 32,342 ft in 7 minutes and a distance of 44 nm.
On final approach to runway 23L at KTYS, the aircraft descended from 1,730 ft agl to 52 ft agl in 49 seconds and was recorded as having scored on the stabilisation gates.
Landing was executed on runway 23L, whose total length is 2,619 m. The threshold speed was noted as high at 140 kt; touchdown occurred 121 m beyond the touchdown zone with a speed of 118 kt and a vertical rate of minus 173 fpm. Alignment at touchdown was very good. Local weather reported a temperature of 26 °C, wind 7 kt from 0°, a 5 kt crosswind and a 5 kt tailwind.
The rollout covered a total landing distance of 1,421 m, equivalent to 54 % of the runway, and the aircraft’s centreline alignment was slightly off by 14.0 m.
After landing, the aircraft taxied back to the parking area in less than 1 minute, traveling less than 1 nm.
In total, the flight covered 132 nm, required 25 minutes of airborne time, and consumed 209 kg of fuel.
The approach to Runway 27 was initiated with a visual reference to the threshold, but unfortunately, the aircraft touched down prematurely, 1,000 feet short of the designated landing zone. The touchdown speed of 133 knots was also above the recommended threshold, indicating a potential loss of control during the landing phase. However, the touchdown rate of -189 feet per minute was satisfactory, suggesting that the pilot maintained a stable descent.
Upon touchdown, the aircraft's alignment with the centreline was significantly off, deviating by 195,553.3 meters. This excessive deviation was also observed during the rollout phase, where the aircraft remained misaligned by 195,509.8 meters. The total landing distance of 968 meters, accounting for 54% of the runway, was also higher than expected. The local weather conditions, with a temperature of 30 degrees Celsius and a crosswind of 10 knots, may have contributed to the pilot's difficulties in maintaining a stable approach and touchdown.
The overall score of 35.1% reflects the subpar performance during the landing phase. The combination of a premature touchdown, excessive touchdown speed, and significant deviations from the centreline during both touchdown and rollout phases resulted in a disappointing outcome. The pilot will need to focus on improving their approach and touchdown techniques to achieve a more satisfactory score.
