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.
Side view — the last 1,524 m of the approach.
Plan view — the first 1,524 m of the 1,996 m runway, to the same scale as the side view.
The 90 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The flight began with taxiing from the parking to the runway at Detroit Metropolitan Wayne County Airport, taking approximately 5 minutes and covering less than 1 nautical mile. The aircraft then departed from runway 03L, with a takeoff distance of 1,448 meters, which was 56% of the runway length. The liftoff speed was 152 knots.
As the aircraft climbed, it encountered local weather conditions of -2°C temperature and a wind of 17 knots at 310°. The crosswind was 17 knots, while the headwind was 3 knots. The enroute climb started 1 mile northeast of the airport, with the aircraft ascending from 1,644 feet above sea level to 33,778 feet, an increase of 32,134 feet in 23 minutes, covering 145 nautical miles.
The enroute level cruise began 5 miles north of Lawrence Park, Pennsylvania, and lasted 31 minutes, covering 193 nautical miles. The aircraft then started its descent 6 miles southwest of Afton, New York, descending from 33,755 feet to 19,468 feet in 5 minutes, covering 35 nautical miles.
The enroute level cruise resumed 3 miles north of Delhi, New York, and lasted 2 minutes, covering less than 1 nautical mile. The aircraft then began its descent again, this time from 19,468 feet to 16,506 feet in 3 minutes, covering 16 nautical miles.
The enroute level cruise started once more 3 miles south of Roxbury Runway Airport, lasting 3 minutes and covering 17 nautical miles. The aircraft then began its descent 4 miles northwest of Woodstock, New York, descending from 16,491 feet to 5,876 feet in 11 minutes, covering 49 nautical miles.
The enroute level cruise resumed 1 mile south of Brewster, New York, lasting 5 minutes and covering 16 nautical miles. The aircraft then began its descent 2 miles southwest of North Stamford, Connecticut, descending from 5,612 feet to 2,178 feet in 5 minutes, covering 13 nautical miles.
The enroute level cruise started overhead Lattingtown, New York, lasting 3 minutes and covering 7 nautical miles. The aircraft then began its final approach to runway 34 at Westchester County Airport, heading 330° at 4 nautical miles and 1,280 feet above ground level.
The landing was successful, with a touchdown speed of 137 knots, which was a little fast. The touchdown rate was heavy at -697 feet per minute, and the runway touchdown position was slightly misaligned by 4.6 meters from the centerline. The total landing distance was 1,335 meters, which was 67% of the runway length.
The aircraft then taxied to the parking from the runway, taking approximately 2 minutes and covering less than 1 nautical mile. The total flight distance was 498 nautical miles, taking 88 minutes, and the aircraft used 2,554 kilograms of fuel.
The CRJ900 aircraft successfully landed at KHPN Westchester County Airport, achieving a score of 92.3%. The final approach was conducted from the southeast, heading 330.0° at 4 nautical miles and 1,280 feet above ground level (agl). The aircraft touched down on runway 34, which has a length of 1,996 meters.
The threshold height was satisfactory, and the threshold speed was maintained at 139 knots, indicating a good approach configuration. However, the touchdown speed of 137 knots was slightly faster than ideal, which may have contributed to a heavy touchdown rate of -697 feet per minute (fpm). This excessive rate may have resulted from the aircraft's high speed at touchdown, which can be mitigated by adjusting the approach speed or flare.
The runway touchdown position was slightly misaligned from the centerline by 4.6 meters, which may have been due to the aircraft's heading or alignment during the final approach. The local weather conditions, with a temperature of 8°C and wind at 10 knots from 269°, resulted in a crosswind of 8 knots and a headwind of 5 knots. These conditions did not appear to significantly impact the landing.
The total landing distance of 1,335 meters was 67% of the runway length, which is within acceptable limits. The runway rollout alignment was very good, indicating that the aircraft's brakes were effectively applied to maintain control and alignment during the rollout phase. Overall, the landing was satisfactory, with some minor areas for improvement, such as adjusting the approach speed to achieve a more ideal touchdown rate.
