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.

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 1,806 m of the approach.
Plan view — the first 1,806 m of the 2,695 m runway, to the same scale as the side view.
The 495 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The Boeing 737-900 taxied from the parking area to runway 07 at UCFL Issyk-Kul, a movement that required 8 minutes and covered 2 nm.
During the departure roll on runway 07, the aircraft accelerated to a liftoff speed of 167 kt and left the ground after traveling 2,674 m, which represented 71 % of the runway length. Ambient conditions were 21 °C with a wind of 3 kt from 216°, a 2 kt cross-wind component and a 3 kt tailwind component.
Climb commenced approximately 1 mile east of UAFL Issyk-Kul International Airport Tamchy. The flight ascended from 6,383 ft asl to 34,735 ft asl, a gain of 28,352 ft, over 21 minutes while covering 129 nm.
Level cruise began 41 nm north-east of UAFZ Kazarman Airport and was maintained for 40 minutes, during which the aircraft progressed 268 nm.
Descent was initiated 7 nm north-west of UTRA Garm Airport. The aircraft descended from 34,519 ft asl to 3,830 ft asl, a loss of 30,689 ft, in 22 minutes and traversed 100 nm.
The final approach to runway 27 at UTDD Dushanbe Airport was flown from the east, on a heading of 270.0°, at 4 nm and 1,259 ft agl.
Landing on runway 27, which is 2,695 m long, occurred with a threshold speed of 150 kt. Touchdown was recorded 85 m beyond the touchdown zone at a speed of 146 kt, a vertical speed of minus 90 fpm, and a lateral deviation of 5.2 m from the centreline. Weather at the time was 23 °C with a wind of 3 kt from 100°, a 1 kt cross-wind component and a 3 kt tailwind component.
The rollout covered a total landing distance of 1,732 m, representing 64 % of the runway, and alignment during the roll was described as very good.
After exiting the runway, the aircraft taxied to the parking area in 3 minutes, covering less than 1 nm.
In total, the flight covered 507 nm, required 95 minutes of airborne time, and consumed 4,733 kg of fuel.
The Boeing 737-900 executed a final approach to runway 27 at UTDD Dushanbe Airport from the east, maintaining a heading of 270.0° at 4 nm and 1,259 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, and local weather reported as 23 °C, wind 3 kt from 100°, crosswind 1 kt and tailwind 3 kt.
Threshold height was good and the threshold speed was good at 150 kt. The aircraft crossed the threshold and the touchdown point was 85 m beyond the touchdown zone.
Touchdown speed was 146 kt, a little fast, while the touchdown rate was excellent at minus 90 fpm. The runway touchdown position was slightly misaligned by 5.2 m from the centreline and the total landing distance was 1,732 m, representing 64 % of the runway length.
Runway rollout alignment was very good.
With a score of 98.8 % the landing was strong; reducing touchdown speed a few knots will help bring the aircraft closer to the aim point and improve centreline alignment. Fine-tuning flare timing can also minimise the slight offset from the centreline.
