Aircraft YS-11 departed from UBBQ Gabala International Airport, a roll of runway 34 being the initial move. At a takeoff distance of 321 meters, which only utilized nine percent of the runway, and a liftoff speed of 114 knots, the flight took to the skies.
Local weather at the time consisted of a temperature of three degrees Celsius and wind of 11 knots at 160 degrees, which equated to a slight tailwind and negligible crosswind.
The plane immediately began climbing en route overhead the airport, moving from an elevation of 1,323 feet above sea level to 1,596 before rising by an additional 272 feet in only a two-minute period. It spanned a horizontal distance of two nautical miles while achieving this rapid ascent.
The final approach brought the aircraft to the south of the runway 34, descending at 1 nautical mile and hovering 444 feet above ground level before aligning its heading of 348 degrees as it prepared for landing.
On touchdown, aircraft YS-11 made an optimal use of speed and distance, with 98 knots being the threshold speed, though marginally beneath its intended target. The aircraft had a speed at touchdown at 96 knots and a relatively brief touchdown distance of 191 meters.
The landing speed and distance were satisfactory, but the touchdown rate turned out to be a little steeper with -450 feet per minute and landed 13.5 meters off-center on the runway. Following the landing, the distance covered on the runway was 943 meters, which represented 27 percent of the runway's total length. As the YS-11 rolled out, it deviated from the runway by 12.8 meters.
Considering the given weather conditions during both the takeoff and the landing, the plane utilized a total fuel of 17 kilograms covering a short distance of 3 nautical miles in 3 minutes.

The aircraft in question is the YS-11, which successfully landed at UBBQ Gabala International Airport. The final approach to runway 34 was initiated from the south, with the aircraft heading 348.0° at a distance of 1 nautical mile and an altitude of 444 feet above ground level (agl). The landing was executed on a runway with a length of 3,474 meters.
The threshold height was reported as good, but the threshold speed was slightly below the target at 98 knots. Despite this, the touchdown distance was satisfactory at 191 meters. The touchdown speed of 96 knots was also within acceptable limits. However, the touchdown rate was somewhat hard at -450 feet per minute (fpm), which may indicate a slightly aggressive approach.
The landing was further complicated by the local weather conditions, with a temperature of 3°C and a wind speed of 11 knots from a direction of 160°. This resulted in a crosswind of 1 knot and a tailwind of 11 knots, which may have affected the aircraft's stability and control during the landing. The runway touchdown position was misaligned by 13.5 meters from the centerline, which could have contributed to the slightly hard touchdown rate.
The total landing distance was 943 meters, which is approximately 27% of the runway length. This is a relatively short landing distance, indicating that the pilot executed a good approach and touchdown. However, the runway rollout alignment was slightly misaligned by 12.8 meters from the centerline, which may indicate some difficulty in maintaining control during the rollout phase.
Overall, the landing was successful, but there were some minor issues with the approach and touchdown. The pilot's skills and experience were likely sufficient to handle the challenging weather conditions and maintain control of the aircraft throughout the landing.
