MY FS FLIGHTS
Flight Score
Arrival
Keep the back pressure coming once the flare is established, holding the nose up through to touchdown instead of easing it.
What happened: The flare arrested the sink but 197 fpm of it came back before touchdown, and in flights like this one that returning sink usually carries through to a firm or hard touchdown at 244 fpm.
Watch for: Vertical speed indicator: the sink held near zero all the way through touchdown, not allowed to build back up.
Turn speed is limited by lateral load on the tyres and the people in the back, and lateral acceleration goes with the square of speed. On an illustrative 25 m turn radius, 10 kt produces about 0.11 g of side load, while 20 kt produces about 0.43 g. Doubling the speed quadruples the load. That square law is the entire content of the "10 knots in turns" rule, and it tells you why a slightly-too-fast turn feels fine and a moderately-too-fast one throws the cabin crew across the galley.

From brake release to the end of the climb, against time, then the takeoff point by point.
Rotated at 146 kt, and lifted off at 163 kt 3.7 s later, the nose coming up at 2.2° a second. Climb 3 averaged 201 kt, 22 kt over its 179 kt target.
Two traces from brake release: the airspeed on top, and below it the pitch, which is how far the nose is above the horizon. The figures at liftoff are the pitch then and how fast the nose came up, in degrees a second. The shaded stretch is Climb 3, the part of the climb scored on holding the climb speed.
The takeoff, point by point
Side view from the start of the roll to the end of Climb 3 at 913 ft.
Reached 35 ft with 7,644 ft of runway left; gear up at 47 ft, inside the 400 ft that gets full marks; then climbing at 2,410 fpm on average to 913 ft.
The takeoff from the side: the height above the runway against the distance along it. The numbers along the runway are the speeds reached at each point. Lifting off in the amber last quarter of the runway costs marks for the roll length. The gear-up ring is coloured by its mark. The shaded stretch is Climb 3, scored on its average speed against the target.
Plan view the roll down the 13,466 ft runway.
Rolled from 286 ft in, never more than 2 ft off the centreline. Airborne 33 % of the way down the runway, before the 75 % line.
The roll from above, with your left at the top. The line is where the wheels went, and "widest" is the furthest you drifted off the centreline. Lifting off before the amber 75 % line gets full marks for the roll length.
The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
The final from 4 nm.
Profile height against the 3° glideslope, with its 1° band in green.
On the glideslope from 4 nm to 0.8 nm, then low to the threshold (up to 100 ft under).
Your height above the runway against the distance still to go. The glideslope is the steady descent path to the aiming point, 1,000 ft past the threshold: 3° here, which is about 320 ft for every nautical mile out, crossing the threshold at about 50 ft. The row under the distances is the height it puts you at. Inside the green band your path is drawn green; outside it, amber.
Plan distance off the extended centreline, your left at the top, with the 1° band. Sideways distances are drawn 24× larger than distances along the final.
Inside the 1° band all the way from 4 nm, never more than 50 ft off the centreline.
Looking down from above, flying left to right towards the runway: up the page is left of the centreline, down is right. Sideways distances are stretched so that small drifts show, so a line that looks wild here may be only a few tens of feet. The labels are how far off you were at each distance, amber when outside the band.
The rest of the report
The Boeing 737-800 taxied from the parking area to runway 35L at LTFM İstanbul Airport, a movement that lasted 11 minutes and covered 1 nm.
Take-off was performed on runway 35L. The aircraft used 4,504 ft of runway, which is 33 % of the available length. Rotation occurred at 146 kt. Local weather reported a temperature of 62 °F, wind 9 kt from 030°, giving a crosswind component of 5 kt and a headwind component of 8 kt.
Initial climb to 1,000 ft agl took 20 seconds, with an average climb rate of 2,018 fpm and a speed of 202 kt at the top of the segment. The subsequent climb from 1,326 ft asl to 35,914 ft asl lasted 18 minutes, covered 116 nm and began 1 mile north-west of LTFM İstanbul Airport (Arnavutköy).
Cruise was maintained at 36,000 ft asl for 359 minutes, covering 2,502 nm, beginning 5 miles west of Malkara.
Descent from 35,995 ft asl to 1,169 ft asl took 28 minutes and covered 139 nm, starting 26 miles south of GQNJ Akjoujt Airport (Akjoujt).
A go-around was executed on runway 06 at GQNO Nouakchott-Oumtounsy International Airport when the aircraft was at 479 ft agl.
On the subsequent final approach to runway 06 at GQNO, the aircraft descended from 1,316 ft agl to 99 ft agl in 115 seconds. Stabilisation checks at 1,000 ft and 500 ft above the runway were all met: gear down, landing flap, sink rate, on glideslope, on centreline, on speed, wings level.
Landing on runway 06 used the full runway length of 8,244 ft. The threshold height was good and the threshold speed was 126 kt, described as good. The flare was noted as a great landing flare. Touchdown occurred 1,321 ft down the runway at a speed of 118 kt, judged good, with a touchdown rate of minus 244 fpm, described as fair. The touchdown point was slightly misaligned by 19 ft from the centreline. Local weather at landing was temperature 97 °F, wind 12 kt from 060°, giving a crosswind component of 2 kt and a headwind component of 11 kt. No bounce occurred. Total landing distance was 2,910 ft, 35 % of the runway, and the rollout alignment was perfect.
After landing, the aircraft taxied to the parking area, a movement that lasted 4 minutes and covered less than 1 nm.
The flight covered a total distance of 2,800 nm, lasted 431 minutes and consumed 34,123 lbs of fuel.
