What held you back

Arrival Touchdown — Touchdown distance was 768 m at 66 %, Touchdown rate was -270 fpm. at 78 %, −0.68 points
Departure Climb 3 — climb speed 216 kt against 179 kt at 79 %, −0.57 points
Departure Taxi — peak speed in a turn 20 kt at 82 %, −0.47 points

Top opportunity

Shorten the long landing

Arrival Touchdown

Next time

Fly a stabilized approach and flare to touch down at the target point of 457 m.

What happened: Touchdown occurred past the normal point, landing 311 m beyond the target distance. This pattern typically reduces the margin available for stopping before the runway end.

Watch for: Watch touchdown point against the 457 m marker.

Departure

Reduce climb power and pitch to hold the climb speed closer to target.

What happened: The climb speed during the departure climb was faster than the target.

Ground effect becomes significant below about one wingspan of height. A Cessna 172, with a 36 ft span, enters ground effect at flare height - the float it feels in the hold-off is ground effect arriving on cue. An A320, with a span around 117 ft, has been in ground effect since before the threshold and there is no sudden cushion to feel, only a gradual reduction in induced drag that lengthens any float you allow.

Flight narrative

The aircraft taxied from the parking area to the runway, a movement that lasted 5 minutes and covered 1 nm.

Departure roll was conducted on runway 21R at VTBD Don Mueang International Airport; the take-off run required 1,236 m, representing 33 % of the runway length, and liftoff was achieved at 149 kt. Ambient conditions were 30 °C with a wind of 2 kt from 255°, providing a 2 kt headwind and a 2 kt crosswind.

The first en-route climb began 1 mile north of VTLA Lak Si Airport. In 2 minutes the aircraft ascended from 1,054 ft asl to 7,981 ft asl, an increase of 6,927 ft while covering 10 nm.

A level cruise segment started 1 mile south-east of Bang Bua Thong and lasted 2 minutes, during which 7 nm were flown at cruise altitude.

The second climb commenced 5 miles north-west of Bang Bua Thong. Over 22 minutes the aircraft rose from 7,992 ft asl to 31,860 ft asl, gaining 23,868 ft and traversing 161 nm.

A subsequent cruise phase began 5 miles north-east of Kamphaeng Phet, lasting 3 minutes and covering 25 nm at the cruise level.

Descent began 8 miles west of Ban Dan Lan Hoi; the aircraft descended from 31,999 ft asl to 2,354 ft asl, a loss of 29,645 ft in 19 minutes while covering 106 nm.

Final approach to runway 36 at VTCC Chiang Mai International Airport was executed from the south, on a heading of 0.0° at 4 nm and 1,307 ft agl.

Landing on runway 36 was performed on a runway 3,404 m long; the threshold speed was 144 kt, and touchdown occurred 351 m beyond the touchdown zone at 143 kt with a smooth vertical speed of minus 119 fpm. Weather at the time was 26 °C with a wind of 1 kt from 360°, yielding a 1 kt headwind and no crosswind. The total landing distance measured 1,756 m, equivalent to 52 % of the runway.

Runway rollout alignment was reported as perfect, completing the landing roll without deviation.

The aircraft taxied from the runway to the parking area, a movement that took 1 minutes and covered less than 1 nm.

Overall, the flight covered 317 nm, required 55 minutes of elapsed time, and consumed 2,898 kg of fuel.

Landing Summary

The Boeing 737-800 completed the final approach to runway 36 at VTCC Chiang Mai International Airport from the south on a heading of 0.0° at 4 nm and 1,307 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 was 26 °C with wind 1 kt from 360°, cross-wind 0 kt and head-wind 1 kt.

During the threshold and flare phase the aircraft enjoyed a good threshold height, but the threshold speed was slightly above target at 144 kt and the touchdown point was 351 m beyond the touchdown zone.

Touchdown occurred with a speed of 143 kt, described as a little fast, while the vertical rate was smooth at minus 119 fpm and runway touchdown alignment was perfect.

Rollout alignment remained perfect and the aircraft used a total landing distance of 1,756 m, representing 52 % of the 3,404 m runway.

To tighten the already strong performance, reduce the approach and touchdown speeds to the target values and aim to touch down nearer the designated touchdown zone, which will further optimise runway usage.

Threshold speed was good at 144 kt. Target 140 kt
Flare
97.03 %
The flare tracked the target profile closely. The aircraft floated down the runway before touching. Touchdown was 768 m past the threshold. Threshold speed was not the cause here - hold the aim point on the approach and let the aircraft settle rather than holding it off, and the touchdown comes back to the numbers.
