MY FS FLIGHTS
Flight Score
Arrival
Take the power back earlier on final, so the aircraft settles onto the path and the speed comes back to 116 kt together. Do not push down for the height: that only adds speed.
What happened: You crossed the threshold at 76 ft agl, 26 ft agl above the 50 ft agl target, and at 129 kt, 13 kt over the 116 kt threshold speed. High and fast together is energy the runway has to absorb, and this touchdown came 324 m beyond the aim point.
Watch for: Airspeed indicator: 116 kt on short final, then 50 ft agl over the threshold
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 1,699 m of the approach.
Plan view — the first 1,699 m of the 2,748 m runway, to the same scale as the side view.
Touched down 781 m past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The Cessna 750 Citation X taxied from the parking area to runway 22L at KMDW Chicago Midway International Airport in 15 minutes, covering a distance of 3 nm.
During the departure roll on runway 22L, the aircraft used 736 m of runway, representing 42 % of the available length, and lifted off at 142 kt. Ambient conditions were a temperature of 21 °C, wind from 225° at 3 kt, with a 3 kt headwind and no cross-wind component.
The initial climb began 1 mile east of Bedford Park, Illinois, climbing from 1,601 ft asl to 27,995 ft asl - an altitude gain of 26,394 ft - in 18 minutes while traversing 114 nm.
Level cruise commenced 3 miles north-east of 1IS2 Triple Creek Airport, Bement, Illinois, lasting 5 minutes and covering 40 nm.
Descent started 4 miles south-east of Tower Hill, Illinois, descending from 27,258 ft asl to 7,895 ft asl - a loss of 19,363 ft - over 8 minutes and 52 nm.
A second climb was initiated 2 miles north-west of 1LL5 Justison Airport, Hillsboro, Illinois, climbing from 7,903 ft asl to 9,252 ft asl, an increase of 1,349 ft in 3 minutes while covering 15 nm.
The next descent began 5 miles south-east of Litchfield, Illinois, dropping from 9,187 ft asl to 5,008 ft asl - a decrease of 4,179 ft - in 2 minutes and 7 nm.
A further cruise segment started 3 miles north of New Douglas, Illinois, lasting 7 minutes and spanning 30 nm.
Descent continued 1 mile north-east of Elsah, Illinois, from 4,993 ft asl to 4,009 ft asl, a loss of 983 ft in 2 minutes over 6 nm.
The aircraft then cruised 1 mile south-west of Grafton, Illinois, for 2 minutes, covering 6 nm.
A descent segment began 6 miles north-east of 45MO Waldmeister Farm Airport, St Peters, Missouri, descending from 3,971 ft asl to 2,399 ft asl - a reduction of 1,572 ft - in 2 minutes and 6 nm.
Cruise resumed 2 miles west of 3SQ St Charles, Illinois, for 2 minutes, covering 6 nm.
Climb was performed 1 mile north-west of 1H0 Creve Coeur, St Louis, Missouri, rising from 2,399 ft asl to 3,005 ft asl, an increase of 606 ft in 2 minutes while traveling 6 nm.
A level cruise over KCHG Chesterfield Airport, Missouri, lasted 3 minutes and covered 14 nm.
Descent began 1 mile north-west of O’Fallon, Missouri, dropping from 3,000 ft asl to 2,499 ft asl - a loss of 501 ft - in 2 minutes and 5 nm.
The final cruise segment started 1 mile east of 45MO Waldmeister Farm Airport, St Peters, Missouri, lasting 3 minutes and covering 9 nm.
The aircraft entered final approach to runway 12L at KSTL St Louis Lambert International Airport from the north-west, on a heading of 122.0°, 4 nm out and 1,292 ft agl.
Landing on runway 12L, which is 2,748 m long, the threshold height of 76 ft agl and threshold speed of 129 kt were above target. Touchdown occurred 361 m beyond the touchdown zone at a speed of 118 kt, with a touchdown rate of minus 272 fpm and a lateral deviation of 8.6 m from the centreline. Local weather reported a temperature of 20 °C, wind from 225° at 3 kt, a 3 kt cross-wind and a 1 kt tailwind. Total landing distance measured 1,614 m, representing 59 % of the runway.
Runway rollout alignment was slightly off centreline by 15.2 m.
After landing, the aircraft taxied to the parking area in 6 minutes, covering 1 nm.
In total, the flight covered 326 nm, required 75 minutes of airborne time, and consumed 2,246 kg of fuel.
The Cessna 750 Citation X approached runway 12L at KSTL from the north-west on a heading of 122.0° at 4 nm and 1,292 ft agl. The final approach was assessed as stabilised at the 1,000 ft gate, with gear, flaps, sink rate, glideslope and centreline all within limits. Local weather was 20 °C with a 3 kt wind from 225°, including a 3 kt crosswind component and a 1 kt tailwind component.
At threshold the aircraft encountered a height of 76 ft agl, which was well above the target, and a threshold speed of 129 kt, also well above the target. The flare proceeded from these conditions.
Touchdown occurred 361 m beyond the designated touchdown zone with a speed of 118 kt, noted as a little fast, and a vertical rate of minus 272 fpm, rated fair. The touchdown point was misaligned by 8.6 m from the centreline.
The aircraft rolled out over a total landing distance of 1,614 m, representing 59 % of the runway length, and the rollout alignment was slightly misaligned by 15.2 m from the centreline.
To refine future landings, aim to achieve the prescribed threshold height and speed to reduce the overshoot beyond the touchdown zone, and adjust the flare to place the touchdown point nearer the aim point while maintaining centreline alignment.
