Maintain the centreline
A small uncorrected heading error at 40 knots becomes a metre of offset per second by 100 knots, noticed only at rotation, producing a crabbed liftoff. Root cause is nearly always eyes on the tape instead of the far end of the runway. Small heading changes displace a distant point visibly long before the nearby centreline stripes look wrong.

The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
One stabilised approach gate: five 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.

Side view — the last 1,524 m of the approach.
Plan view — the first 1,524 m of the 1,740 m runway, to the same scale as the side view.
The 51 m touchdown sits inside the full-score zone. The arrival was smooth.
The rest of the report
The flight began with the Beechcraft Duke taxiing from the parking area to the runway at KSAC Sacramento Executive Airport, taking approximately 16 minutes and covering 3 nautical miles. Upon reaching Runway 12, the aircraft departed and lifted off at 86 knots with a takeoff distance of 486 meters, which accounted for 42% of the runway.
En route, the aircraft climbed from 1,038 feet above sea level to 8,972 feet, a gain of 7,934 feet, within 6 minutes and covering 12 nautical miles. This initial climb started overhead Parkway in California. The plane then transitioned into level cruise, maintaining a steady altitude, first south east of Gold River for 3 minutes and covering 13 nautical miles, and subsequently east of Georgetown for 5 minutes and covering 20 nautical miles.
The flight's climb phase resumed as the aircraft ascended from 9,029 feet to 13,583 feet, an increase of 4,554 feet, in 5 minutes while covering 18 nautical miles, located north of the O61 Cameron Cameron Park in California. The plane then entered level cruise for a short duration south west of Tahoma, covering 3 nautical miles. The climb phase continued as the aircraft descended from 13,497 feet to 7,946 feet, a decrease of 5,551 feet, within 5 minutes and covering 11 nautical miles, positioned west of Sunnyside-Tahoe City.
Throughout the flight, the aircraft periodically entered level cruise, alternating with climb or descent phases. One of these instances involved a brief descent from 7,963 feet to 7,508 feet, a decrease of 455 feet, which took place in 2 minutes and covered 3 nautical miles, located south east of Tahoma. The plane cruised at a steady altitude north west of South Lake Tahoe, covering 5 nautical miles within 4 minutes.
Upon reaching its final destination, KTVL Lake Tahoe Airport, the aircraft performed a final approach heading 192.0 degrees at an altitude of 331 feet above ground level, with a target speed of 71 knots for a smooth, controlled descent. The weather conditions at the time of landing were a temperature of 17 degrees Celsius, winds of 4 knots from 190 degrees, with no crosswind but a 3-knot headwind.
The landing was successful, with a touchdown speed of 68 knots and a short touchdown distance of 49 meters. Although the touchdown rate was relatively high at -438 feet per minute, the runway touchdown position was slightly misaligned, being 5.7 meters off the centerline. The total landing distance was just 261 meters, accounting for 15% of the runway length.
Taxiing to the parking area took just 2 minutes, with the aircraft covering less than 1 nautical mile. Overall, the flight distance was 91 nautical miles and took approximately 43 minutes, using a total of 142 kilograms of fuel.
The Beechcraft Duke safely landed on runway 18 at KTVL Lake Tahoe Airport with a final score of 92.6%. The aircraft navigated the final approach from the north with a heading of 192.0° and an altitude of 331 feet above ground level (agl). The crew successfully executed a precise descent onto the runway, achieving a touchdown distance of 49 meters.
Upon landing, the aircraft demonstrated a good control of speed, touching down at 68 knots (kt) which falls within the target range. However, the crew needs to remain vigilant as the threshold speed was slightly below the target of 71 kt, and stall prevention is crucial at this stage. Fortunately, no issues resulted from this brief variance.
Notably, the aircraft achieved an efficient touchdown, with a speed of 68 kt and a relatively short distance of 49 meters. Nonetheless, the touchdown rate was quite steep, at -438 ft per minute (fpm), indicating a significant amount of deceleration during the landing process.
The landing occurred off-centerline by 5.7 meters, which, although not optimal, does not negatively impact the overall performance of the aircraft. Nonetheless, runway alignment is critical for a safe and smooth landing.
Considering the prevailing weather conditions, the aircraft experienced a light headwind of 3 kt, while the crosswind was near-neutral. The temperature at the time of landing was 17°C, which is conducive to aerodynamic performance.
In terms of overall performance, the aircraft achieved an excellent runway roll-out alignment, suggesting the presence of skilled piloting. This indicates that the pilots effectively managed the aircraft's descent and touchdown, ensuring a smooth transfer from takeoff mode to landing mode.
The landing distance of 261 meters was just 15% of the runway length, which is an impressive accomplishment, considering the aircraft's size and class. Overall, the crew demonstrated a high level of proficiency, executing a safe and efficient landing with a few areas for minor improvement.
