What went well

Held the centreline on the roll in a 13 kn crosswind — 1.82 m off at liftoff
Straight touchdown — 2.01 m off the centreline, no bounce
Flare on profile — 100 %

What held you back

Arrival Landing — Threshold speed was good at 142 kt at 0 %, Touched down 65 m short of the threshold, so it was never crossed in the air at 0 %, −3.33 points
Arrival Touchdown — Touchdown rate was -346 fpm at 64 %, Touched down 65 m short of the threshold at 72 %, −0.78 points
Enroute Climb — 250 kt exceeded below 10,000 ft; speed limits at 88 %, −0.52 points

Next time

Departure

Use smoother, smaller aileron inputs to keep the wings level and hold bank angle near wings-level during the climb.

What happened: During the climb, bank angle rose to 7.9°, more roll than the climb out called for.

Watch for: Attitude indicator: wings level during the climb

See Departure Climb 2

Arrival

Reduce power earlier on final to bleed speed back to 138 kt before crossing the threshold.

What happened: You crossed the threshold at 142 kt, 4 kt above the 138 kt target.

Watch for: Airspeed, targeting 138 kt at the threshold.

See Arrival Landing

Every knot above Vref is stored kinetic energy, and energy stored at the threshold must be dissipated in ground effect before the aeroplane will stop flying. Because kinetic energy scales with the square of speed, the excess you must dissipate grows fast. At a 45-knot approach, five knots hot is over a tenth more speed and roughly a quarter more energy to get rid of in ground effect. This is why the fix is never in the flare. It was decided three miles earlier, on final, at the airspeed indicator.

Speed and pitch

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

Rotated at 136 kt, 11 kt below the 147 kt target, and lifted off at 143 kt 3.1 s later, the nose coming up at 3.4° a second. Climb 3 averaged 154 kt, 12 kt under its 166 kt target.

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 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 figures at liftoff are the pitch then and how fast the nose came up, in degrees a second. The shaded stretch is Climb 3, the part of the climb scored on holding the climb speed.

Side view from the start of the roll to the end of Climb 3 at 697 ft.

Reached 35 ft with 326 m of runway left; gear up at 33 ft, inside the 400 ft that gets full marks; then climbing at 1,490 fpm on average to 697 ft.

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. The gear-up ring is coloured by its mark. The shaded stretch is Climb 3, scored on its average speed against the target.

Plan view the roll down the 2,186 m runway.

Rolled from 114 m in, drifted 4.8 m right of the centreline and was back on it to lift off, in 13 kn of crosswind from the right. Airborne 69 % of the way down the runway, before the 75 % line.

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 stabilisation gates

Two stabilised approach gates, each with seven checks, where the approach path is 1,000 ft and 500 ft above the runway. They are the approach's score: the checks passed out of the checks that ran.

How to read this

Each line is one of the gate checks, run along the whole final rather than only at the gates: green where it would have passed, amber where it would not. The glideslope, centreline and speed lines use the bands in the charts beside this card. The sink rate is allowed what the glideslope needs at your ground speed plus 600 fpm, the wings 10° of bank, and the gear and flap are read from when you moved the levers. The bottom line is green where every check held at once, ignoring blips shorter than 0.2 nm, and the sentence above it says from where it held to the threshold. A ring is a stabilisation gate, where the checks in the table were taken.

The final from 4 nm, with the stabilisation gates on it.

Profile height against the 3° glideslope, with its 1° band in green.

Inside the glideslope band from 4 nm to the threshold, never more than 100 ft above the slope.

How to read this

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 320 ft for every nautical mile out, crossing the threshold at about 50 ft. The row under the distances is the height it puts you at. Inside the green band your path is drawn green; outside it, amber. A ring is a stabilisation gate: green when every check there passed, amber with the failed checks named beside it.

Plan distance off the extended centreline, your left at the top, with the 1° band. Sideways distances are drawn 16× larger than distances along the final.

How to read this

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 35 kt fast at the 1,000 ft gate, closing to 21 at 500 ft and 10 at the threshold.

Inside the speed band all the way, between +2 kt and +10 kt on the approach speed of 138 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.

The flare100.00

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.

The crosswind

4 kt across from the left, which takes about 2° of crab to hold the centreline at 142 kt. Touched down with 1° of it still on, wings level.

Wind 299° at 19 kt · 18 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.

The stop

From 124 kt at touchdown to taxi speed (30 kt) in 29 s, an average deceleration of 0.18 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.

Side view — the last 1,524 m of the approach.

Began the flare at 40 ft, 289 m before the threshold; crossed the threshold at 59 ft, close to the 50 ft target. Touched down 65 m before the threshold.

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.

Flight narrative

Departing from Ronald Reagan Washington National Airport (KDCA), the CRJ900 began its journey by taxiing from the parking area to the runway, a process that took approximately 7 minutes and covered a distance of 1 nautical mile. Upon reaching runway 01, the aircraft initiated its departure roll, accelerating down the 1,522-meter-long runway, which accounted for 69% of its total length. The aircraft lifted off at a speed of 144 knots, overcoming the local headwind of 1 knot and a crosswind of 14 knots from a direction of 80 degrees.

As the aircraft climbed away from the airport, it began its enroute climb, ascending from an initial altitude of 754 feet above sea level to a cruising altitude of 36,018 feet, a vertical gain of 35,263 feet. This climb phase, which lasted 14 minutes, covered a distance of 144 nautical miles. The aircraft then entered a level cruise phase, maintaining a steady altitude and airspeed for 24 minutes as it covered a distance of 592 nautical miles. The enroute descent phase began 6 miles south of MU33 Harrison Airport Hurdland, where the aircraft descended from 35,851 feet to 2,288 feet, a vertical loss of 33,563 feet, in just 11 minutes, covering a distance of 110 nautical miles.

Upon reaching the final approach phase, the CRJ900 began its descent towards runway 31 at Des Moines International Airport (KDSM), approaching from the southeast. The aircraft touched down before the threshold, with a touchdown speed of 142 knots, which was slightly faster than recommended. The touchdown rate was also hard, at -500 feet per minute. The runway touchdown position was slightly misaligned, deviating 4.5 meters from the centerline. The aircraft then taxied to the parking area, a process that took 8 minutes and covered a distance of less than 1 nautical mile. The total flight distance was 854 nautical miles, with a total flight time of 61 minutes and a fuel consumption of 4,009 kilograms.
