Maintain the centreline

See Departure Roll

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.

Lifted off at 46 kt with 4.2° 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. The shaded stretch is Climb 3, the part of the climb scored on holding the climb speed.

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. The shaded stretch is Climb 3, scored on its average speed against the target.

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

4 kt across from the right, which takes about 5° of crab to hold the centreline at 50 kt. Touched down with 5° of it still on, wings level.

Wind 262° at 5 kt · 0 kt head · 4 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.

Side view — the last 1,232 ft of the approach.

Crossed the threshold at 12 ft, 38 ft below the 50 ft target. Touched down 192 ft in, 808 ft short of the ideal 1,000 ft.

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 1,232 ft across. The dashed line is the ideal, 50 ft over the threshold and down 1,000 ft 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.

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 29 at KCHI Challis Airport. The aircraft took off with a takeoff distance of 155 feet, which was 16% of the runway length. The liftoff speed was 46 knots. At the time of departure, the local weather conditions were a temperature of 45°F and a wind speed of 5 knots from a direction of 262°. The crosswind component was 3 knots, while the headwind component was 4 knots.

As the aircraft climbed away from the airport, it began its enroute climb, which started overhead KCHI Challis Airport. The aircraft climbed from an altitude of 5,566 feet above sea level to 5,698 feet above sea level, an increase of 132 feet in just 1 minute, covering a distance of 2 nautical miles. The climb was a smooth and efficient one, with the aircraft making good progress.

However, the enroute descent was a different story. It started 2 miles northwest of KCHI Challis Airport and involved a descent from 5,685 feet above sea level to 5,015 feet above sea level, a decrease of 670 feet in 2 minutes, covering a distance of 3 nautical miles. The descent was a bit more challenging, with the aircraft losing altitude at a slightly faster rate than expected.

The enroute level cruise started 2 miles south of C53 Lower Loon Creek and lasted for 4 minutes, covering a distance of 2 nautical miles. This was a relatively stable and steady phase of the flight, with the aircraft maintaining a consistent altitude and airspeed.

The final approach to runway 16 at C53 Lower Loon Creek was made from the north, with the aircraft heading 173.0° at an altitude of 31 feet above ground level. The landing was made on a runway with a length of 1,232 feet, and the threshold height was good. However, the threshold speed was slightly below target at 52 knots.

The touchdown point was very long, using more than 50% of the available runway. The touchdown speed was a little fast at 50 knots, and the touchdown rate was fair at -232 feet per minute. The runway touchdown position was slightly misaligned by 12 feet from the centerline. The local weather conditions at the time of landing were a temperature of 46°F and a wind speed of 5 knots from a direction of 262°, with a crosswind component of 5 knots and a headwind component of 0 knots.

Despite the slightly challenging landing, the runway rollout alignment was very good. The total landing distance was 957 feet, which was 78% of the runway length. The total flight distance was 7 nautical miles, and the flight used 2 pounds of fuel. Overall, the flight was a relatively smooth and efficient one, with some minor challenges during the landing phase.
