Flight Score
Departure
Lower the nose and add power to raise climb speed to 179 kt.
What happened: Climb speed was 157 kt against a target of 179 kt, running 22 kt slow through the climb.
Watch for: Airspeed indicator against the climb target of 179 kt.
Arrival
Track the centreline through touchdown using small rudder corrections against a point at the far end of the runway.
What happened: The aircraft touched down off the centreline at 29 ft, and drifting off centreline at touchdown usually carries through into the rollout, as it did here with alignment reaching 17 ft.
Watch for: Watch runway centreline position, keeping deviation inside the limit through touchdown and rollout.
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 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 5,000 ft of the approach.
Plan view — the first 5,000 ft of the 7,580 ft runway, to the same scale as the side view.
Touched down 1,797 ft past the threshold — beyond the full-score zone. The arrival was smooth.
The rest of the report
The Boeing 737-800 taxied from the parking area to runway 34L at KEUG Mahlon Sweet Field, a movement that required 7 minutes and covered less than 1 nm.
During the departure roll on runway 34L, the aircraft accelerated over a takeoff distance of 4,980 ft, representing 62 % of the runway, and lifted off at 148 kt. Ambient conditions were 63 °F with a wind of 3 kt from 320°, including a 2 kt crosswind and a 2 kt headwind.
Climb commenced approximately 1 mile north of KEUG, with the airplane climbing from 1,347 ft asl to 36,707 ft asl, an altitude gain of 35,360 ft achieved in 20 minutes while covering 124 nm.
The first level cruise began about 1 mile west of Phoenix, Oregon, and persisted for 74 minutes, during which the aircraft flew 540 nm.
Descent was initiated 3 miles northwest of Santa Monica, California, descending from 37,003 ft asl to 6,390 ft asl, a loss of 30,613 ft in 17 minutes and traversing 105 nm.
A brief level cruise followed, starting 2 miles southeast of KMYF Montgomery-Gibbs Executive Airport, lasting 2 minutes and covering 5 nm.
The final descent began overhead Spring Valley, California, with the aircraft descending from 5,999 ft asl to 1,524 ft asl, a reduction of 4,475 ft over 6 minutes and 16 nm.
The aircraft entered final approach to runway 27 at KSAN San Diego International Airport from the east, aligned on a heading of 286.0° at 4 nm and 1,495 ft agl.
Touchdown occurred on runway 27, whose length is 7,580 ft, with a threshold speed of 141 kt. The aircraft contacted the runway 434 ft beyond the touchdown zone at a speed of 135 kt, and the vertical speed at touchdown was minus 208 fpm. The touchdown point was offset by 23 ft from the centreline. Weather at the time was 75 °F with a wind of 2 kt from 320°, including a 1 kt crosswind and a 1 kt headwind. Total landing distance measured 3,652 ft, representing 48 % of the runway.
Runway rollout alignment was reported as very good, confirming the aircraft remained on the centreline during deceleration.
After landing, the Boeing 737-800 taxied from the runway to the parking area in 4 minutes, covering less than 1 nm.
Overall, the flight covered 798 nm, required 130 minutes of airborne time, and consumed 11,660 lbs of fuel.
The final approach to runway 27 at KSAN San Diego International Airport was flown from the east on a heading of 286.0° at 4 nm and 1,495 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.
During the threshold and flare phase the threshold height was good and the threshold speed was good at 141 kt.
Touchdown occurred 434 ft beyond the touchdown zone with a touchdown speed of 135 kt, which was good. The touchdown rate was fair at minus 208 fpm and the runway touchdown position was slightly misaligned by 23 ft from the centreline. Total landing distance was 3,652 ft, representing 48 % of the 7,580 ft runway.
Rollout alignment was very good; the aircraft remained on the centreline through the rollout under calm conditions with a temperature of 75 °F, wind 2 kt from 320°, crosswind 1 kt and headwind 1 kt.
Minor refinements should focus on reducing the sink rate during flare to bring the touchdown rate closer to the ideal range and on tightening centreline tracking to eliminate the 23-ft offset, which will further improve an already strong 96.0 % score.
