Flight Score
Keep the taxi smooth
Turn speed is limited by lateral load on the tyres and the people in the back, and lateral acceleration goes with the square of speed. On an illustrative 25 m turn radius, 10 kt produces about 0.11 g of side load, while 20 kt produces about 0.43 g. Doubling the speed quadruples the load. That square law is the entire content of the "10 knots in turns" rule, and it tells you why a slightly-too-fast turn feels fine and a moderately-too-fast one throws the cabin crew across the galley.

Two stabilised approach gates, each with six checks at 1,000 ft and 500 ft above the runway.
The approach, gate by gate
Side view — the last 1,524 m of the approach.
Plan view — the first 1,524 m of the 1,828 m runway, to the same scale as the side view.
The 300 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The Boeing 737-700 taxied from the parking area to runway 27 at KSAN San Diego International Airport, a movement that required three minutes and covered less than one nautical mile.
During the departure roll on runway 27, the aircraft accelerated to a liftoff speed of 139 kt, using a takeoff distance of 1,260 m which represented 55 % of the available runway; ambient temperature at the time was 21 °C.
Climb commenced one mile west of KSAN, where the airplane rose from 996 ft asl to 40,536 ft asl, an altitude gain of 39,540 ft achieved in 49 minutes while traversing 390 nm.
Level cruise began four miles north-west of 02AZ Winchester Farm Airstrip in Willcox, Arizona, and was maintained for 88 minutes, during which the aircraft covered 683 nm.
Descent was initiated four miles north-west of XA40 Richardson Regional Heliport - Bush Highway in Richardson, Texas, with the flight descending from 40,757 ft asl to 1,289 ft asl, a loss of 39,469 ft accomplished in 17 minutes over a distance of 113 nm.
The final approach to runway 14 at KGLS Scholes International Airport at Galveston was flown from the north-west on a heading of 140.0°, intercepting the approach at four nautical miles out and an altitude of 1,271 ft agl.
Landing on runway 14 was executed on a runway 1,828 m long; the threshold speed was recorded at 128 kt, touchdown occurred 301 m down the runway at 122 kt, and the vertical speed at touchdown was minus 176 fpm. Weather at the airport indicated a temperature of 31 °C, wind from 229° at 4 kt, with a crosswind component of 4 kt and no headwind.
The total landing distance measured 756 m, representing 41 % of the runway length, and the rollout alignment was described as perfect.
After exiting the runway, the aircraft taxied back to the parking area in less than one minute, covering less than one nautical mile.
In summary, the flight covered 1,193 nm, required 160 minutes of airborne time, and consumed 6,936 kg of fuel.
The Boeing 737-700 received a 99.7 % score while on final approach to runway 14 at KGLS Scholes International Airport, heading 140.0° from the north-west at 4 nm and 1,271 ft agl; the approach was assessed as unstable at the 1,000 ft gate because the sink rate was too high, with local weather reporting a temperature of 31 °C, wind 4 kt from 229°, a 4 kt crosswind and no headwind.
At threshold the aircraft maintained a good height and achieved a good threshold speed of 128 kt.
Touchdown occurred 301 m down the runway at a good speed of 122 kt, with a good vertical rate of minus 176 fpm and a very good runway touchdown alignment.
The total landing distance was 756 m, representing 41 % of the 1,828 m runway, and the rollout alignment was perfect.
Focus on reducing the sink rate to meet the stabilized-approach criteria at the 1,000 ft gate; correcting this will convert the already excellent performance into a fully stable approach.
