Flight Score
Departure
On the roll, make small rudder corrections against a point at the far end of the runway to hold the centreline.
What happened: On the roll the aircraft drifted 29 m off the centreline, and heading then varied by -0.8° through the first climb segment; drifting off centreline on the roll like this usually carries a heading variation into the climb, which in turn usually carries extra bank into the second climb segment, seen here as 19°.
Watch for: Heading indicator: wings level and track straight through the climb
Arrival
Add power on short final to hold speed at 58 kt, correcting the slow threshold speed before it carries through to the flare.
What happened: Threshold speed was slow at 57 kt against 58 kt, and touchdown followed short of the aim point at 105 m. Crossing the threshold slow like this usually carries the touchdown short.
Watch for: Airspeed indicator against 58 kt on short final.
There are several things that can go wrong during the flare, carrying too much speed over the threshold, starting the flare at the wrong height and inconsistent flight control inputs, all contribute to a poor flare resulting in a hard touchdown or a float down the runway.

The roll
Rotated early, and quickly
The nose came up at 52 kt, 7 kt before the 59 kt rotate speed, and rose at 7.9° a second, faster than the 1.4 to 3.7 other Cessna 172 pilots fly.
Early and quick together is the classic tail-strike setup: the nose reaches its liftoff attitude before the aircraft has the speed to fly. Wait for the rotate speed, then pull smoothly at the normal rate for this aircraft and let it lift off at its own attitude.
Liftoff and climb
Plan view the roll down the 609 m runway.
Rolled from the start of the runway, drifted left of the centreline, 29 m at the widest, and lifted off 14 m left. Airborne 59 % of the way down the runway, before the 75 % line.
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.
Side view from the start of the roll to 58 m. The distance scale changes past the runway end.
Reached 11 m at the runway end; then climbing at 1.7 m/s on average to 58 m.
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 dark stretch of the roll is the run with the nose up and the wheels still on, with its length and time under the runway.
Speed and pitch from brake release to the end of the climb, against time.
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 dashed green line is the speed to rotate at for this aircraft at its weight, and the green dot is where the nose started to come up. The grey band is the run between the nose coming up and the wheels leaving the runway. The figures at liftoff are the pitch then and how fast the nose came up, in degrees a second. The rotation detail below draws the rotation against the rates for this aircraft and its tail-strike pitch, where the slope reads properly. The grey dashed line across the pitch is the attitude held from 35 ft to the end: a nose held steady is a climb speed that holds, and the airspeed trace sits directly above it to compare.
Rotation detail the pitch over the seconds from rotation to 11 m, where the slope reads properly.
The pitch over the seconds from the nose starting to come up to 11 m, stretched so the slope reads properly. The green dot is where the nose started up, the grey band runs to the wheels leaving, and the figures at liftoff are the pitch then and how fast the nose came up. The two dashed green lines rising from the rotation point are 1.4 to 3.7° a second, the middle half of rotation rates flown by other Cessna 172 pilots over the last 180 days (64 takeoffs). A trace steeper than both green lines is a faster rotation than most, one shallower than both a slower one.
The final from 4 nm.
Profile height against the 3° glideslope, with its 2° band in green.
Inside the glideslope band from 0.8 nm, where the final began, to the threshold, never more than 82 m above the slope.
Your height above the runway against the distance still to go. The glideslope is the steady descent path to the aiming point, 305 m past the threshold: 3° here, which is about 98 m for every nautical mile out, crossing the threshold at about 15 m. The row under the distances is the height it puts you at. Inside the green band your path is drawn green; outside it, amber.
Plan distance off the extended centreline, your left at the top, with the 1° band. Sideways distances are drawn 3× larger than distances along the final.
Inside the 1° band all the way from 0.8 nm, never more than 213 m off the centreline.
Looking down from above, flying left to right towards the runway: up the page is left of the centreline, down is right. Sideways distances are stretched so that small drifts show, so a line that looks wild here may be only a few tens of feet. The labels are how far off you were at each distance, amber when outside the band.
Speed against the approach speed. The green band runs from 5 kt slow to 29 kt fast at the 305 m gate, closing to 17 at 152 m and 10 at the threshold.
Inside the speed band all the way, between −7 kt and +9 kt on the approach speed of 58 kt.
Your indicated airspeed down the final, against the approach speed for this aircraft at its landing weight. The band allows 5 kt slow and more on the fast side further out, closing as you get lower, because the speed is expected to come off on the way down. The figures are knots above (+) or below (−) the approach speed.
Over the threshold
The aircraft touched down before the threshold
Everything the flare is measured against - the profile, the crossing height, the aim point - is referenced to a threshold this landing never reached, so read the numbers below as what happened short of the runway, not on it. Landing short is the fault to fix before anything about the hold-off is worth judging.
Touchdown
Rollout
Taxi in
Side view — the last 609 m of the approach.
Began the flare late, at 3 m; crossed the threshold at 15 m, close to the 15 m target. Touched down 105 m before the threshold.
The last stretch of the approach and the touchdown, from the side. The height is stretched so that the last few feet show: 24 m top to bottom, against 609 m across. The dashed line is the ideal, 15 m 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.
Plan view — the full 609 m runway, to the same scale as the side view.
No crosswind: nothing to correct for. Touched down with the nose 1° right of the track, wings level.
Wind 090° at 2 kt · 2 kt tail · 0 kt across
The runway from above, with your left at the top. Touching down inside the green bracket scores full marks for the distance. The shaded part is the rollout, up to where it ended. 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. The sentence gives the nose against the direction you were actually moving as the wheels touched, and the steepest bank as they touched, the figure the touchdown's Bank tile marks. The rest of it is shown for reading, not marked.
Touched down 105 m short of the threshold. The 1.79 G arrival is the firm side of smooth.
The stop — touchdown to taxi speed.
From 61 kt at touchdown to taxi speed (30 kt) in 11 s, an average deceleration of 0.14 g.
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.
The rest of the report
