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 34 ft off the runway centreline.
Watch for: Watch runway alignment against the centreline, correcting with small rudder inputs.
See Departure Roll
Arrival
Take the power back earlier on final, so the aircraft settles onto the path and the speed comes back to 118 kt together. Do not push down for the height: that only adds speed.
What happened: You crossed the threshold at 61 ft agl, 11 ft agl above the 50 ft agl target, and at 127 kt, 9 kt over the 118 kt threshold speed. High and fast together is energy the runway has to absorb, and this touchdown came 722 ft beyond the aim point.
Watch for: Airspeed indicator: 118 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.
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 5,000 ft of the approach.
Plan view — the first 5,000 ft of the 7,608 ft runway, to the same scale as the side view.
Touched down 2,222 ft 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 05R at KEDW Edwards Air Force Base, a taxi of 27 minutes covering 5 nm.
Take-off was on runway 05R. The aircraft used 4,070 ft of runway, 27 % of the available length, and rotated at 135 kt. Local weather was 84 °F with wind 6 kt from 090°, a 3 kt crosswind and a 5 kt headwind.
Initial climb to 1,000 ft agl took 28 seconds, averaging 1,693 fpm and reaching 175 kt at the top of the climb.
The climb continued from 3,311 ft asl to 44,995 ft asl in 24 minutes, covering 170 nm, with a brief level-off at 13,000 ft asl.
Level flight was held at 45,000 ft asl for 97 minutes, covering 869 nm, beginning 2 mi south-west of Golden Shores.
Descent from 45,002 ft asl to 1,397 ft asl took 33 minutes over 186 nm, starting 3 mi south-west of Bertram, with brief level-offs at 12,000 ft asl, 6,000 ft asl and 3,200 ft asl.
Final approach to runway 31L at KHOU William P Hobby Airport began with a descent from 1,396 ft agl to 66 ft agl in 109 seconds. Stabilisation checks at 1,000 ft and 500 ft above the runway were met for gear down, sink rate, glideslope, centreline, speed and wings level. Configuration was gear down at 2,031 ft agl, 189 kt; final flap position 4 was selected at 1,335 ft agl, 157 kt.
Landing on runway 31L (runway length 7,608 ft) had a threshold height of 61 ft agl, which was above target, and a threshold speed of 127 kt, slightly above target. The flare was described as perfect; the aircraft floated before touchdown. Touchdown occurred 806 ft beyond the touchdown zone at 115 kt, a little fast, with a fair touchdown rate of minus 238 fpm and perfect runway-touchdown alignment. No bounce occurred.
Total landing distance was 3,956 ft, 52 % of the runway, and rollout alignment was perfect. Local weather at landing was 63 °F with wind 4 kt from 360°, a 3 kt crosswind and a 2 kt headwind.
After landing, the aircraft taxied to parking in 10 minutes, covering less than 1 nm.
The flight covered a total of 1,237 nm in 174 minutes and used 4,922 lb of fuel.
