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 127 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 343 fpm.
Watch for: Vertical speed indicator: the sink held near zero all the way through touchdown, not allowed to build back up.
Preparing for a stable approach will give you time to decide on whether to attempt the landing or going around. Too much altitude with a high sink rate will result in carrying too much speed onto the runway. Configuring flaps and the gear late also won't help the speed decay.

The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
Two stabilised approach gates, each with seven checks, where the approach path is 1,000 ft and 500 ft above the runway. They are the approach's score: the checks passed out of the checks that ran.
At the 500 ft gate: speed 20 kt FAST on the reference speed of 118 kt.
The approach, gate by gate
Side view — the last 1,524 m of the approach.
Plan view — the first 1,524 m of the 3,542 m runway, to the same scale as the side view.
The 364 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The Boeing 737-700 taxied from the parking area to runway 36 at HSSK Khartoum International Airport in 4 minutes, covering a distance of 1 nm.
During the departure roll on runway 36, the aircraft accelerated to a liftoff speed of 142 kt and left the ground after a takeoff run of 1,507 m, which represented 50 % of the runway length; ambient temperature was 34 °C with a wind of 2 kt from 090°, a cross-wind component of 2 kt and no head-wind.
The initial en-route climb began overhead HSSK, climbing from 2,233 ft asl to 38,996 ft asl, an altitude gain of 36,763 ft achieved in 35 minutes while covering 258 nm.
Cruise commenced 20 nm north-east of HHTS Tessenei Airport and was maintained for 140 minutes, during which the aircraft flew 1,089 nm at level flight.
A subsequent climb segment started at latitude 15.2347958 and longitude 55.596576, raising the aircraft from 39,487 ft asl to 40,984 ft asl, a gain of 1,497 ft in 3 minutes and traversing 25 nm.
The next cruise phase began at latitude 15.339185 and longitude 56.0367869, lasting 221 minutes and covering 1,759 nm at the assigned cruise altitude.
Descent was initiated 3 nm east of Sini, India, with the aircraft descending from 41,007 ft asl to 1,299 ft asl, a loss of 39,708 ft over 21 minutes while covering 142 nm.
On final approach to runway 01R at VECC Netaji Subhash Chandra Bose International Airport, the aircraft reduced altitude from 1,342 ft agl to 53 ft agl in 105 seconds and met the stabilisation gate criteria.
Landing on runway 01R, which is 3,542 m long, was executed with a threshold speed of 122 kt; touchdown occurred 365 m down the runway at 117 kt, a rate of minus 302 fpm, and a lateral deviation of 4.0 m from the centreline. Local conditions were 32 °C with a wind of 4 kt from 280°, a cross-wind component of 3 kt and no head-wind. The total landing roll measured 837 m, representing 24 % of the runway, and rollout alignment was recorded as very good.
Runway rollout was completed with the aircraft remaining well aligned on the centreline, confirming the satisfactory termination of the landing phase.
The aircraft taxied from the runway to the parking stand in 1 minute, covering less than 1 nm.
In total, the flight covered 3,280 nm, took 428 (as reported), and consumed 15,924 kg of fuel.
The approach to runway 01R at VECC Netaji Subhash Chandra Bose International Airport was assessed as stabilised at the 1,000 ft gate, with gear, flaps, sink rate, glideslope, centreline and speed all within limits. The aircraft descended from 1,342 ft agl to 53 ft agl in 105 seconds and earned points on the stabilisation gates, contributing to the overall score of 95.5 %.
At threshold the height was good and the threshold speed was good at 122 kt, indicating the aircraft was correctly configured for the flare.
Touchdown occurred 365 m down the runway, a distance judged good, with a touchdown speed of 117 kt that was a little fast. The touchdown rate was firm at minus 302 fpm and the touchdown point was slightly misaligned by 4.0 m from the centreline.
The total landing distance was 837 m, representing 24 % of the 3,542 m runway, and the runway rollout alignment was very good. Weather conditions were 32 °C temperature, wind 4 kt from 280°, crosswind 3 kt and no headwind.
A minor reduction in touchdown speed would bring the aircraft closer to the target speed and help soften the firm rate, while a small adjustment to lateral control during flare can eliminate the 4.0 m centreline offset. Maintaining the high stabilisation standards will preserve the strong overall score.
