Maintain the centreline
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.
One stabilised approach gate: five checks where the approach path is 500 ft above the runway. The 1,000 ft gate was not assessed, because the approach did not join final that far out.
At the 500 ft gate: sink rate above what the glideslope needed, off the runway's 3° glideslope and off the centreline.

Plan view — the full 1,082 m runway, to the same scale as the side view.
The 483 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The flight began at the Britton Municipal Airport, KBTN, where the Kodiak 100 was taxiing from the parking area to the runway. This process took 5 minutes and covered less than 1 nautical mile.
As the aircraft departed from runway 13, a takeoff distance of 245 meters was achieved, which was 19% of the runway. The liftoff speed was 76 knots, and the local temperature was 13 degrees Celsius.
The enroute climb started approximately 2 miles south east of the KBTN airport, where the aircraft climbed from 2,351 feet above sea level to 9,258 feet, achieving an increase of 6,908 feet in 5 minutes and covering 4 nautical miles.
After reaching the desired altitude, the enroute descent began 3 miles north east of the KBTN airport, where the aircraft descended from 9,126 feet to 6,802 feet, experiencing a decrease of 2,324 feet in 3 minutes and covering 10 nautical miles.
Later, the aircraft initiated an enroute level cruise at 4 miles west of the ND90 airport, which lasted 14 minutes and covered 40 nautical miles. This was followed by an enroute descent 9 miles north east of the 5ND5 airport, where the aircraft descended from 6,807 feet to 2,485 feet, experiencing a decrease of 4,322 feet in 5 minutes and covering 13 nautical miles.
The enroute level cruise resumed 2 miles south of Valley City, lasting 2 minutes and covering 3 nautical miles. An enroute descent then occurred overhead Valley City, where the aircraft descended from 2,429 feet to 1,993 feet, experiencing a decrease of 436 feet in 2 minutes and covering 2 nautical miles.
The final approach was initiated from the north, heading at 163.0 degrees at 1 nautical mile and 568 feet above ground level, with the landing being conducted on runway 17 at the Barnes Co Mun airport. The runway length was 1,082 meters, and the threshold height was above target at 66 feet above ground level.
The touchdown speed was 65 knots, which was a little fast, while the touchdown rate was good at -153 feet per minute. However, the touchdown point was very long, using more than 50% of the available runway. Additionally, the runway touchdown position was misaligned by 13.4 meters from the centreline.
The total landing distance was 868 meters, which was 80% of the runway. The runway rollout alignment was slightly misaligned by 9.7 meters from the centreline. The flight's final stage involved taxiing to the parking area from the runway, which took 1 minute and covered less than 1 nautical mile.
The total flight distance was 76 nautical miles, with a total flight time of 37 minutes. The aircraft used 94 kilograms of fuel during the flight.
The aircraft in question, a Kodiak 100, was undergoing a landing exercise at Barnes County Municipal Airport (KBAC) on a runway designated as 17. Given the conditions, the final approach took place from the north, at a bearing of 163.0°, roughly 1 nautical mile away from the runway with an altitude of 568 feet above ground level.
Upon reaching the threshold, it became apparent that the aircraft landed ahead of its intended touchdown position. The threshold height was above the target at 66 feet, which could be attributed to various factors such as aircraft performance, air density, or even the pilot's decisions. Furthermore, the threshold speed was well above the target at 79 knots, which often results from an overly aggressive flare or an attempt to descend too quickly towards the runway.
The touchdown point itself fell into the "very long" category, meaning more than 50% of the available runway was utilized. With a runway length of 1,082 meters, this translates to approximately 541 meters being consumed upon initial contact. This can be particularly hazardous, as it gives the pilot reduced runway length for deceleration and may result in an increased risk of veering off the paved surface.
A landing speed at 65 knots was slightly fast for a typical landing touchdown, implying a somewhat aggressive approach or an attempt to land ahead of schedule. However, from a flight dynamics perspective, the rate of descent at -153 feet per minute was indeed within acceptable parameters.
One significant concern in this exercise was the runway alignment following the landing. The landing was performed with a crosswind of 6 knots and a tailwind of 2 knots, neither of which appears critical enough to warrant significant deviation from the centerline. Nevertheless, the actual touchdown point deviated from the runway centerline by a considerable 13.4 meters.
A review of the wind conditions at the time indicates a moderate temperature of 12 °C and gentle wind speeds averaging 6 knots coming primarily from the northwest. These conditions should have presented no significant obstacles to the pilot.
Finally, following the touchdown, the aircraft rolled off the runway for a considerable 868 meters, or approximately 80% of the runway, before coming to a stop. Post-landing, the runway rollout alignment showed some deviation from the centerline, specifically drifting to the left by 9.7 meters. While this presents an added challenge for post-landing taxi navigation, it ultimately did not prove detrimental to the aircraft's safety.
