Flight Score
Departure
Reduce climb power to bring speed back to 117 kt and hold it there.
What happened: Climb speed was 23 kt fast at 140 kt during the climb.
Watch for: Airspeed indicator: 117 kt in the climb
Arrival
Track the centreline through touchdown using small rudder corrections against a point at the far end of the runway.
What happened: The aircraft touched down off the centreline at 48 ft, and drifting off centreline at touchdown usually carries through into the rollout, as it did here with alignment reaching 27 ft.
Watch for: Watch runway centreline position, keeping deviation inside the limit through touchdown and rollout.
Every knot above Vref is stored kinetic energy, and energy stored at the threshold must be dissipated in ground effect before the aeroplane will stop flying. Because kinetic energy scales with the square of speed, the excess you must dissipate grows fast. At a 45-knot approach, five knots hot is over a tenth more speed and roughly a quarter more energy to get rid of in ground effect. This is why the fix is never in the flare. It was decided three miles earlier, on final, at the airspeed indicator.

The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
One stabilised approach gate: seven checks where the approach path is 500 ft above the runway. The 1,000 ft gate was not assessed, because the approach did not join final that far out. These checks are the approach's score.
The approach, gate by gate
Side view — the last 5,000 ft of the approach.
Plan view — the first 5,000 ft of the 10,986 ft runway, to the same scale as the side view.
The 991 ft touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The Cirrus Vision SF50 taxied from the parking area to runway 26R at KLAS Harry Reid International Airport, a movement that required 8 minutes and covered 2 nm.
Takeoff was executed on runway 26R, with a ground roll of 1,596 ft representing 12 % of the runway length. The aircraft lifted off at 98 kt. Ambient conditions were temperature 108 °F, wind 14 kt from 230 °, with a cross-wind component of 9 kt and a head-wind component of 11 kt.
Climb commenced 1 mile west of KLAS, ascending from 3,218 ft asl to 30,001 ft asl - a gain of 26,782 ft - over 25 minutes while covering 89 nm.
The first cruise segment began 5 miles north-west of NV36 Imvite Airport, Amargosa Valley, and persisted for 103 minutes, during which 538 nm were flown.
Descent started 13 miles west of 00S McKenzie Bridge State Airport, Blue River, descending from 29,768 ft asl to 9,361 ft asl - a loss of 20,407 ft - in 12 minutes and covering 64 nm.
A subsequent cruise leg originated 1 mile south of OR40 Dietz Airpark, Canby, lasting 7 minutes and spanning 30 nm.
The next descent began 3 miles east of OG29 Mc Kinnon Airpark, Sandy, dropping from 8,789 ft asl to 8,329 ft asl - a decrease of 461 ft - in 2 minutes over 7 nm.
Following that, a cruise segment started 7 miles south-west of North Bonneville, Washington, and continued for 2 minutes, covering 6 nm.
Descent resumed 3 miles south-east of 4WA1 Brown’s Cape Horn Airport, Washougal, falling from 7,883 ft asl to 2,185 ft asl - a loss of 5,698 ft - in 7 minutes while traveling 18 nm.
The final cruise phase was overhead Fairview, Oregon, lasting 2 minutes and encompassing 3 nm.
During the final approach to runway 28L at KPDX Portland International Airport, the aircraft approached from the south-east on a heading of 296.0°, at 3 nm and 1,594 ft agl.
Landing on runway 28L, which measures 10,986 ft, the threshold speed was recorded at 74 kt, slightly below target. Touchdown occurred 980 ft down the runway at 66 kt, with a smooth touchdown rate of minus 113 fpm and a lateral deviation of 26 ft from the centreline. Weather at the time was temperature 63 °F, wind 4 kt from 340 °, with a cross-wind component of 3 kt and a head-wind component of 3 kt.
The rollout distance totaled 2,107 ft, representing 19 % of the runway, and runway alignment during rollout was very good.
After landing, the aircraft taxied to the parking area in 2 minutes, covering less than 1 nm.
In total, the flight covered 764nm, took 170, and used 1,114 lbs of fuel.
The Cirrus Vision SF50 executed the final approach to runway 28L at KPDX Portland International Airport from the south-east, tracking a heading of 296.0° at 3 NM and 1,594 ft agl. At the 1,000 ft gate the approach was assessed as unstable, with a sink rate that was too high and the aircraft off the glideslope.
During the threshold and flare segment the aircraft maintained a good threshold height, and the threshold speed was a little below the target at 74 kt.
Touchdown occurred 980 ft down the runway at a speed of 66 kt, which was judged good, and the vertical rate was smooth at minus 113 fpm. The touchdown point was misaligned by 26 ft from the centreline, and the total landing distance measured 2,107 ft, representing 19 % of the 10,986-ft runway. Ambient conditions were 63 °F with a wind of 4 kt from 340°, comprising a 3-kt crosswind and a 3-kt headwind.
Runway rollout alignment was very good, and the overall landing received a score of 96.5 %.
Refine the approach to achieve a stabilized profile by the 1,000 ft gate, correcting sink-rate and glideslope deviations. Aim to keep the touchdown point within a few feet of the centreline to preserve the excellent rollout alignment.
