Departure
Make small rudder corrections against a fixed point at the far end of the runway to hold the centreline during the roll.
What happened: The aircraft drifted 18 ft off the runway centreline during the ground roll, and wing drift like that usually keeps reappearing as bank in the climb, with 3.4° of bank in the first climb segment and 4.4° still showing in the second.
Watch for: Heading indicator: steady on the runway centreline during the roll, then wings level through the climb.
Arrival
Add power on short final to hold 189 kt over the threshold instead of letting speed decay.
What happened: Threshold speed was 41 kt below the 189 kt target, and the sink was arrested at 79 ft while already slow, so the aircraft settled as the speed ran out, producing a firm touchdown at 1,735 fpm.
Watch for: Airspeed indicator: 189 kt at the threshold
Arrive slow and the sink rate at the threshold is already above schedule, the flare is short because there is no energy to extend it, and the touchdown is hard in a way that feels exactly like a late flare. Diagnosing a slow arrival as a late flare is the catastrophic misread: you respond by flaring earlier, which bleeds more speed, which makes the next one worse. The tiebreaker is threshold speed against VRef, not feel. Never diagnose a flare without it.

The threshold, the flare and the hold-off. The approach that led to it is the stabilisation gates below.
One stabilised approach gate: six 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.
At the 500 ft gate: off the centreline, wings not level and speed above the reference speed.
The approach, gate by gate
Side view — the last 4,735 ft of the approach.
Plan view — the full 4,735 ft runway, to the same scale as the side view.
The 204 ft touchdown sits inside the full-score zone. The 2.96 G arrival is the firm side of smooth.
The rest of the report
The flight began with a quick taxiing process from the parking area to the runway, taking less than 1 minute and covering a distance of less than 1 nautical mile. The aircraft, a Boom XB-1, then departed from runway 12 at the Mojave Airport (KMHV), with a takeoff distance of 4,769 feet, which accounted for 43% of the runway. The liftoff speed was 190 knots, and the local weather conditions at the time of takeoff were a temperature of 58°F and a wind speed of 10 knots at 48°.
As the aircraft began its enroute climb, it started 1 mile southeast of the Mojave Airport and climbed from an altitude of 3,752 feet above sea level to 4,979 feet, an increase of 1,226 feet in just 1 minute, covering a distance of 5 nautical miles. The climb was a smooth and efficient process, allowing the aircraft to reach its desired altitude quickly.
After reaching its cruising altitude, the aircraft began its enroute descent, starting 5 miles south of California City. The descent from 4,992 feet to 2,918 feet, a decrease of 2,074 feet, took 2 minutes and covered a distance of 6 nautical miles. The aircraft then began its final approach to runway 22 at the Mojave Airport, coming in from the northeast at a heading of 236.0° and an altitude of 133 feet above ground level.
The landing on runway 22 was successful, with a touchdown distance of 197 feet and a touchdown speed of 145 knots. However, the touchdown rate was quite heavy, at -1,351 feet per minute, and the runway touchdown position was significantly misaligned from the centerline by 65 feet. The local weather conditions at the time of landing were a temperature of 54°F and a wind speed of 10 knots at 50°, with a tailwind of 10 knots.
The total landing distance was 2,004 feet, accounting for 42% of the runway, and the runway rollout alignment was misaligned from the centerline by 53 feet. Despite some minor issues with the landing, the flight was overall successful, with a total flight distance of 13 nautical miles and a fuel consumption of 1,886 pounds.
The Boom XB-1 aircraft has successfully landed at KMHV Mojave Airport, but with some notable areas for improvement. The final approach to runway 22 was initiated from the north east, heading 236.0° at 1 nm and 133 ft above ground level (agl). The aircraft's approach speed was well below the target threshold speed of 148 kt, which is a good sign, as it indicates that the pilot was taking a cautious approach to avoid stalling the aircraft.
Upon touchdown, the aircraft's performance was satisfactory, with a touchdown distance of 197 ft and a touchdown speed of 145 kt. However, the touchdown rate was quite heavy, at -1,351 fpm, which may indicate that the pilot could have applied more gentle braking to reduce the rate of descent. The runway touchdown position was significantly misaligned by 65 ft from the centreline, which may have been due to a slight deviation in the pilot's alignment or a slight crosswind.
The local weather conditions at the time of landing were relatively calm, with a temperature of 54°F and a wind speed of 10 kt at 50°. The crosswind component was negligible, but the tailwind component was 10 kt, which may have contributed to the aircraft's misaligned touchdown. The total landing distance was 2,004 ft, which is 42% of the runway length of 4,735 ft. The runway rollout alignment was also misaligned by 53 ft from the centreline, which may indicate that the pilot could have applied more gentle braking to maintain alignment.
Overall, while the Boom XB-1 aircraft has successfully landed at KMHV Mojave Airport, there are some areas for improvement in terms of alignment and braking. With some adjustments to the pilot's technique, the aircraft's performance can be further optimized to achieve a smoother and more controlled landing.
