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 24 ft off the runway centreline.
Watch for: Watch runway alignment against the centreline, correcting with small rudder inputs.
See Departure Roll
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.

Plan view — the first 5,000 ft of the 8,982 ft runway, to the same scale as the side view.
The 1,009 ft touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The flight began with a short taxiing period from the parking to the runway, taking approximately 1 minute and covering less than 1 nautical mile. The aircraft, a Boeing 737-900, then departed from runway 36R at KDFW Dallas Fort Worth International Airport. The takeoff distance was 7,046 feet, which accounted for 52% of the runway. The liftoff speed was 164 knots.
As the aircraft took to the skies, it encountered local weather conditions of 89°F temperature and a 5-knot wind at 280°. The crosswind was 4 knots, and the headwind was 1 knot. The enroute climb started 1 mile south east of Grapevine, Texas, and reached an altitude of 36,999 feet, an increase of 35,425 feet from the initial 1,574 feet above sea level. This climb took 23 minutes and covered 153 nautical miles.
Following the climb, the aircraft entered a level cruise phase, which started 4 miles east of Cromwell, Oklahoma. This phase lasted for 40 minutes and covered 285 nautical miles. The enroute descent began 1 mile west of the Cayton Pony Express Airport in Maysville, Missouri, and descended from 37,000 feet to 2,865 feet above sea level, a decrease of 34,135 feet in 20 minutes, covering 104 nautical miles.
The aircraft then entered another level cruise phase, which started 2 miles south east of the Tuinstra Airfield in Indianola, Iowa. This phase lasted for 2 minutes and covered 6 nautical miles. The final approach to runway 31 at KDSM Des Moines International Airport was from the south east, heading 312.0° at 4 nautical miles and 1,300 feet above ground level.
However, the aircraft performed a go-around at 243 feet above ground level. The landing was eventually made on runway 31, with a runway length of 8,982 feet. The threshold height was good, and the threshold speed was also satisfactory at 148 knots. The touchdown distance was 1,015 feet, which was within acceptable limits. The touchdown speed was 144 knots, which was slightly fast, and the touchdown rate was firm at -345 feet per minute.
The runway touchdown position was slightly misaligned by 18 feet from the centreline. The local weather conditions at the time of landing were 36°F temperature and a 3-knot wind at 359°, with a crosswind of 2 knots and a headwind of 2 knots. The total landing distance was 4,243 feet, which accounted for 47% of the runway. The runway rollout alignment was very good.
The final taxiing period from the runway to the parking took 4 minutes and covered 1 nautical mile. The total flight distance was 583 nautical miles, and the flight duration was 1 hour and 44 minutes. The aircraft used 10,899 pounds of fuel during the flight.
The Boeing 737-900 aircraft successfully landed at Des Moines International Airport (KDSM) on runway 31, achieving a score of 96.2%. The final approach was initiated from the southeast, heading 312.0° at a distance of 4 nautical miles and an altitude of 1,300 feet above ground level (agl).
The aircraft touched down on the runway with a good threshold height, indicating a smooth and controlled descent. The threshold speed of 148 knots was also within the acceptable range, demonstrating the pilot's ability to manage the aircraft's speed during the landing phase. The touchdown distance of 1,015 feet was also satisfactory, indicating that the aircraft was able to maintain a stable and controlled approach.
However, the touchdown speed of 144 knots was slightly faster than the recommended speed, which may have resulted in a firmer touchdown rate of -345 feet per minute (fpm). This could potentially have caused some stress on the aircraft's landing gear and may have affected the overall ride quality for passengers.
The runway touchdown position was slightly misaligned by 18 feet from the centerline, which may have been due to a slight deviation in the pilot's alignment during the final approach. Despite this, the runway rollout alignment was very good, indicating that the pilot was able to maintain control of the aircraft during the rollout phase.
The local weather conditions at the time of the landing were characterized by a temperature of 36°F and a wind speed of 3 knots from 359°. The crosswind and headwind components were both 2 knots, which was relatively light and did not pose a significant challenge to the pilot. The total landing distance of 4,243 feet was 47% of the runway length, which is within the acceptable range for a Boeing 737-900 aircraft.
Overall, the landing was successful, and the pilot demonstrated good control and management of the aircraft during the final approach and rollout phases. However, there were some minor deviations from the recommended procedures, which may have affected the overall performance of the landing.
