Flight Score
Maintain the centreline
Next time
Rotate the moment the speed tape reaches 125 kt, not after it.
What happened: Rotation was held until 139 kt, 14 kt past the 125 kt rotation target. Carrying that much extra speed into rotation usually adds unwanted energy right at liftoff.
Watch for: Airspeed indicator against the 125 kt rotation target.
Arrival
Reduce power earlier on final to bring threshold speed back to 118 kt.
What happened: You crossed the threshold at 133 kt against a target of 118 kt, and touchdown ended up well past the normal point. Carrying excess threshold speed usually carries the touchdown long as the aircraft floats before settling.
A small uncorrected heading error at 40 knots becomes a metre of offset per second by 100 knots, noticed only at rotation, producing a crabbed liftoff. Root cause is nearly always eyes on the tape instead of the far end of the runway. Small heading changes displace a distant point visibly long before the nearby centreline stripes look wrong.

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 six 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 1,524 m of the approach.
Plan view — the first 1,524 m of the 1,831 m runway, to the same scale as the side view.
Touched down 505 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The Citation X taxied from the parking area to runway 33L at KBOS Logan International Airport in 16 minutes, covering a distance of 3 nm.
During the departure roll on runway 33L, the aircraft used 1,009 m of runway, representing 33 % of the available length, and lifted off at 139 kt. Ambient conditions were 21 °C with a wind of 6 kt from 330°, including a 1 kt cross-wind component and a 5 kt head-wind component.
Climb commenced over Chelsea, Massachusetts, with the airplane ascending from 996 ft asl to 39,998 ft asl, an increase of 39,001 ft achieved in 15 minutes while covering 61 nm.
The first cruise segment began over Three Rivers, Massachusetts, lasting 5 minutes and extending 30 nm.
Descent began 3 mi southeast of Otis, Massachusetts, with the aircraft descending from 39,999 ft asl to 3,654 ft asl, a loss of 36,345 ft in 20 minutes and traversing 125 nm.
A second cruise phase started over Hopatcong, New Jersey, lasting 5 minutes and covering 20 nm.
The next descent segment occurred over Short Hills, New Jersey, where altitude fell from 2,510 ft asl to 2,005 ft asl, a decrease of 505 ft in 2 minutes across 4 nm.
A third cruise interval was flown over Irvington, New Jersey, lasting 3 minutes and spanning 6 nm.
Final approach to runway 06 at KTEB Teterboro Airport was conducted from the southwest, on a heading of 47.0° at 4 nm and 1,265 ft agl.
Landing on runway 06, which is 1,831 m long, was executed with a threshold speed of 134 kt. Touchdown occurred 84 m beyond the touchdown zone at 124 kt, with a vertical speed of minus 151 fpm and a lateral deviation of 3.5 m from the centreline. Local weather was 19 °C with a wind of 4 kt from 20°, including a 2 kt cross-wind and a 4 kt head-wind component.
The rollout covered a total landing distance of 1,102 m, representing 60 % of the runway, and alignment during the rollout was very good.
After landing, the aircraft taxied to the parking area in 8 minutes, traveling 2 nm.
In total, the flight covered 258 nm, required 75 minutes of elapsed time, and consumed 979 kg of fuel.
The Citation X made its final approach to runway 06 at KTEB Teterboro Airport from the south-west on a heading of 47.0° at 4 nm and 1,265 ft agl. The approach was assessed as stabilised at the 1,000 ft gate, with gear, flaps, sink rate, glideslope and centreline all within limits.
At threshold the aircraft encountered good threshold height and established the required threshold speed of 134 kt. The flare was executed and the aircraft touched down 84 m beyond the touchdown zone with a touchdown speed of 124 kt and a touchdown rate of -151 fpm. The touchdown point was slightly misaligned by 3.5 m from the centreline.
The landing distance recorded was 1,102 m, representing 60 % of the 1,831 m runway, and the rollout alignment was very good.
With a final score of 99.3 % the landing was excellent; the primary area for refinement is the 3.5 m lateral deviation at touchdown, which can be reduced by fine-tuning the flare to achieve a more centred touchdown. Maintaining the current speed and rate profiles will preserve the overall high performance.
