Hold the approach speed

See Arrival Final 1

Preparing for a stable approach will give you time to decide on whether to attempt the landing or going around. Too much altitude with a high sink rate will result in carrying too much speed onto the runway. Configuring flaps and the gear late also won't help the speed decay.

Speed and pitch

From brake release to the end of the climb, against time, then the takeoff point by point.

Lifted off at 68 kt with −2.0° of pitch.

How to read this

Two traces from brake release: the airspeed on top, and below it the pitch, which is how far the nose is above the horizon. The figure at liftoff is the pitch then.

How to read this

The takeoff from the side: the height above the runway against the distance along it. The numbers along the runway are the speeds reached at each point. Lifting off in the amber last quarter of the runway costs marks for the roll length.

How to read this

The roll from above, with your left at the top. The line is where the wheels went, and "widest" is the furthest you drifted off the centreline. Lifting off before the amber 75 % line gets full marks for the roll length. The arrow beside the runway is the crosswind, pointing the way the air was moving, so it pushed the aircraft that way.

The crosswind

Little crosswind (1 kt): nothing to correct for. Touched down with the nose 3° left of the track, wings level.

Wind 231° at 4 kt · 4 kt head · 1 kt across

How to read this

The wind is the one recorded at the landing, split along the runway (headwind or tailwind) and across it. To hold the centreline in a crosswind the nose points a little into wind - the crab - and is straightened with rudder just before the wheels touch, often with the into-wind wing lowered to stop the drift. These are the nose against the direction you were actually moving, and the wings, at the moment of touchdown. Shown for reading; not marked.

The stop

From 51 kt at touchdown to taxi speed (30 kt) in 6 s, an average deceleration of 0.29 g.

How to read this

Your ground speed from the moment the wheels touched until you were down to taxi speed, against the distance rolled. A steep line is hard braking, a shallow one a long, gentle roll. For scale, an airliner's lowest autobrake setting decelerates at about 0.15 g, a medium one about 0.3 g. Shown for reading; not marked.

How to read this

The last stretch of the approach and the touchdown, from the side. The height is stretched so that the last few feet show: 80 ft top to bottom, against 1,524 m across. The dashed line is the ideal, 50 ft over the threshold and down 305 m in. The flare ring is where you began raising the nose, and "descent slowed" is where the sink came off; the figures beside them are the sink rate, pitch and speed at that point.

Sink and pitch — through the flare, lined up with the side view.

The sink went from 980 fpm at 42 ft to 800 fpm at touchdown. The nose came up 9.8° on the way down.

Lined up with the side view above, so a point on one sits under the same point of the other. On top, how fast you were coming down: 0 is level, and −600 is 600 ft a minute down. Below, the pitch. In a flare the nose comes up and the descent slows towards 0. The figure at the touchdown line is your touchdown rate.

Flight narrative

The flight began with a departure roll from runway 21 at I08 Cabin Creek US Forest Service Airport. The DHC-2 Beaver aircraft took off with a takeoff distance of 231 meters, which accounted for 55% of the runway. The liftoff speed was 68 knots. At the time of departure, the local weather conditions were characterized by a temperature of 4 degrees Celsius and a wind speed of 7 knots at 312 degrees, resulting in a 7-knot crosswind and no headwind.

As the aircraft climbed, it started its enroute climb overhead the Big Creek Ranger Station, located near the airport. The climb began at an altitude of 4,366 feet above sea level and reached a maximum altitude of 4,469 feet, an increase of 104 feet in just 1 minute. The aircraft covered a distance of less than 1 nautical mile during this climb.

During the flight, the aircraft encountered a go-around at Vines Airstrip, where it climbed to an altitude of 356 feet above ground level. The final approach to landing at Vines Airstrip was made from an altitude of 240 feet above ground level, and the aircraft descended to a touchdown altitude of 0 feet in just 2 seconds. The touchdown speed was 52 knots, which was considered good, but the touchdown rate was very heavy at -805 feet per minute. The touchdown distance was also good, measuring 69 meters.

Following the touchdown, the aircraft underwent a landing rollout at Vines Airstrip, where it reached an altitude of 4,107 feet above sea level. The distance covered during the rollout was 79 meters. The local weather conditions at the time of landing were characterized by a temperature of 3 degrees Celsius and a wind speed of 4 knots at 231 degrees, resulting in a 2-knot crosswind and a 4-knot headwind.

In total, the flight covered a distance of 3 nautical miles and lasted for 3 minutes, consuming 3 kilograms of fuel.
