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 448 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 513 fpm.
Watch for: Vertical speed indicator: the sink held near zero all the way through touchdown, not allowed to build back up.
There are several things that can go wrong during the flare, carrying too much speed over the threshold, starting the flare at the wrong height and inconsistent flight control inputs, all contribute to a poor flare resulting in a hard touchdown or a float down the runway.

The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
One stabilised approach gate for a circuit: seven checks where the approach path is 300 ft above the runway. The 1,000 ft gate is an instrument-approach check and does not apply. These checks are the approach's score.
At the 300 ft gate: glideslope 4.9° against the runway's 2.8°.
The approach, gate by gate
Side view — the last 1,524 m of the approach.
Plan view — the first 1,524 m of the 2,614 m runway, to the same scale as the side view.
The 432 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The Robin DR400 taxied to runway 11 at MDST Cibao International Airport and commenced its take-off roll. The aircraft used 746 m of runway, representing 29 % of the available length, and lifted off at 60 kt. Ambient conditions were 15 °C with a wind of 1 kt from 270°, no cross-wind and a 1 kt tail-wind component.
After departure, the aircraft entered a left-hand pattern on runway 11, covering a distance of 1 nm in 10 seconds.
The subsequent left-hand crosswind leg of the pattern was flown for less than 1 nm, taking 23 seconds to complete.
The downwind segment of the circuit extended 4 nm and was completed in 126 seconds.
During the base-leg turn, the aircraft traversed 2 nm while aligning to a 45-degree angle to the runway, measured at 4.1 °.
On the first final approach to runway 11, the aircraft descended from 884 ft agl to 36 ft agl in 41 seconds and met the stabilisation-gate criteria.
A go-around was executed on runway 11 when the aircraft reached 72 ft agl, after which the approach was aborted.
A second final approach to runway 11 followed, with a descent from 694 ft agl to 25 ft agl over 63 seconds, again satisfying the stabilisation-gate requirements.
The landing was performed on runway 11, whose length is 2,614 m. The threshold speed was recorded as 70 kt, the touchdown distance was 431 m, and touchdown speed was 45 kt. The vertical speed at touchdown was minus 264 fpm, and the touchdown point was offset 6.5 m from the centreline. Weather conditions remained 15 °C, wind 1 kt from 270°, with no cross-wind and a 1 kt tail-wind.
In total, the flight covered 22 nm, required 12 minutes of elapsed time, and consumed 4 kg of fuel.
The final approach to runway 11 at MDST Cibao International Airport was conducted in two passes. In the first pass the aircraft descended from 884 ft agl to 36 ft agl in 41 seconds and received a score on the stabilisation gates. In the second pass the descent was from 694 ft agl to 25 ft agl in 63 seconds, also scoring on the stabilisation gates.
At threshold the aircraft presented a good threshold height and achieved the target threshold speed of 70 kt, indicating an appropriate flare set-up for the landing.
Touchdown occurred 431 m down the runway, with a touchdown speed of 45 kt that was judged good. The vertical touchdown rate was fair at minus 264 fpm and the touchdown point was slightly misaligned by 6.5 m from the centreline.
To improve future performance, attention should be given to moderating the vertical speed to achieve a gentler touchdown rate, and to refining the final alignment to reduce the centreline offset.
