MY FS FLIGHTS
Flight Score
Departure
Make small rudder corrections against a point at the far end to hold the centreline.
What happened: During the ground roll you drifted 11 m off the runway centreline.
Watch for: Watch runway alignment against the centreline, correcting with small rudder inputs.
See Departure Roll
Arrival
Begin the flare with progressive back pressure and keep it coming until the sink is arrested, rather than flying it on flat.
What happened: The nose was barely raised in the flare and little of the sink was taken out, flying the aircraft onto the runway. This pattern usually carries through to a firm touchdown with a noticeable sink rate.
Watch for: Vertical speed indicator: a smoothly reducing sink through the normal flare band, not a steady rate into the runway.
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 seven 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 2,055 m of the approach.
Plan view — the first 2,055 m of the 2,596 m runway, to the same scale as the side view.
The 429 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The Boeing 737-900 taxied from the parking area to runway 23R at MMMX Benito Juárez International Airport, a movement that required 11 minutes and covered 2 nm.
During the departure roll on runway 23R, the aircraft accelerated over a takeoff distance of 1,961 m, representing 57 % of the runway length, and lifted off at 162 kt; ambient temperature was 20 °C with wind from 200° at 9 kt, including a 6 kt crosswind component and a 7 kt headwind.
The initial climb began 1 mile southeast of Mexico City, climbing from 8,578 ft asl to 37,009 ft asl-a gain of 28,431 ft-over 21 minutes while traversing 137 nm.
Level cruise commenced 3 miles southwest of Huehuetlan, lasting 14 minutes and covering 112 nm at the cruise altitude.
A subsequent climb started 7 miles northeast of Llera de Canales, raising the aircraft from 37,001 ft asl to 38,000 ft asl, an increase of 1,000 ft achieved in 2 minutes over a distance of 13 nm.
The next cruise segment began 3 miles south of MMCV General Pedro Jose Mendez International Airport, Ciudad Victoria, and continued for 33 minutes, during which 256 nm were flown.
Descent began 6 miles west of TX27 A P Ranch Encinal in Texas, with the aircraft descending from 37,338 ft asl to 2,061 ft asl-a loss of 35,277 ft-over 22 minutes while covering 121 nm.
For the final approach to runway 22 at KSAT San Antonio International Airport, the aircraft approached from the northeast on a heading of 220.0°, intercepting the glide path at 4 nm and 1,264 ft agl.
Landing on runway 22 was executed on a runway 2,593 m long; the threshold height of 64 ft agl was above target and the threshold speed of 149 kt was slightly above target. Touchdown occurred 426 m from the threshold at 146 kt, with a hard touchdown rate of minus 449 fpm, while runway alignment was very good. Local conditions were 31 °C, wind 10 kt from 110°, a 10 kt crosswind and a 4 kt tailwind. The total landing distance recorded was 1,977 m, representing 76 % of the runway.
Runway rollout proceeded with very good alignment, completing the deceleration phase after the recorded touchdown parameters.
The aircraft taxied from the runway to the parking area in 3 minutes, covering less than 1 nm.
In total, the flight covered 650 nm, required 106 minutes of airborne time, and consumed 4,606 kg of fuel.
The Boeing 737-900 executed the final approach to runway 22 at KSAT San Antonio International Airport from the north-east, maintaining a heading of 220.0° at 4 nm and 1,264 ft agl. Local weather was 31 °C with wind 10 kt from 110°, a 10 kt crosswind component and a 4 kt tailwind component.
At the threshold the aircraft was 64 ft agl, which was above target, and the threshold speed was 149 kt, slightly above target.
Touchdown occurred 426 m down the runway, a good distance, with a speed of 146 kt that was a little fast and a hard rate of descent measured at minus 449 fpm. Runway touchdown alignment was very good.
The total landing distance was 1,977 m, representing 76 % of the 2,593 m runway, and rollout alignment remained very good.
Reduce touchdown speed toward the target and moderate the flare to lessen the hard rate of descent; these adjustments will bring the already strong 90.9 % score even closer to optimal performance.
