What went well

Touchdown 1,301 ft in — inside the full-score zone
Threshold crossed at 30 ft and 157 kt — both inside band
Straight touchdown — 1.1 ft off the centreline, no bounce

What held you back

Firm touchdown — 263 fpm, −0.33 points across the landing and the touchdown
  • Arrival Touchdown · sink rate 263 fpm−0.27
  • Arrival Landing · flare: the descent was not taken out−0.06

Next time

Arrival

Nothing to change in the speed, the height or the flare. Keep the landing attitude held until the mains are on, so the aircraft is not let down onto the runway in the last moment.

What happened: The touchdown rate was 262 fpm. Nothing before it explains that: threshold speed and height were within limits and the flare was flown normally.

Watch for: Touchdown rate: a little less than 262 fpm next time

See Arrival Touchdown

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.

Speed and pitch

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

Rotated at 153 kt, 4 kt above the 149 kt target, and lifted off at 164 kt 3.4 s later, the nose coming up at 2.2° a second. Climb 3 averaged 179 kt, 14 kt under its 193 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 880 ft.

Reached 35 ft with 3,395 ft of runway left; gear up at 62 ft, inside the 400 ft that gets full marks; then climbing at 2,280 fpm on average to 880 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 9,991 ft runway.

Rolled from 245 ft in, never more than 3 ft off the centreline. Airborne 53 % 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.

When the approach was stable

Every check met from 4 nm to the threshold.

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 approach to KBOS 22L

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 140 ft below 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, 1,000 ft 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.

Inside the 1° band all the way from 4 nm, never more than 70 ft off the centreline.

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 39 kt fast at the 1,000 ft gate, closing to 24 at 500 ft and 10 at the threshold.

Inside the speed band all the way, between +0 kt and +6 kt on the approach speed of 157 kt.

How to read this

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.

Excellent landing flare. It lost 3.7 points, partly for taking only 429 fpm of the sink out.

The crosswind

No crosswind: nothing to correct for. Touched down straight, wings level.

Wind 200° at 3 kt · 3 kt head · 0 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 142 kt at touchdown to taxi speed (30 kt) in 40 s, an average deceleration of 0.15 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 6,245 ft of the approach.

Began the flare at 36 ft, 127 ft before the threshold; crossed the threshold at 30 ft, 20 ft below the 50 ft target. Touched down 1,301 ft in, 301 ft past 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 6,245 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.

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

The sink went from 680 fpm at the flare to 260 fpm at touchdown. The nose came up 1.9° on the way down.

How to read this

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 MD-11 departed Indianapolis International Airport (KIND) on runway 23L. The take-off roll was 5,310 ft, which is 53 % of the runway length, and rotation occurred at 153 kt. Local weather was 75 °F with a wind of 2 kt from 120°, a 2 kt crosswind and a 1 kt tailwind.

Initial climb to 1,000 ft agl took 20 seconds, averaging 2,332 fpm and reaching 180 kt at the top of the segment. The aircraft then climbed from 1,723 ft asl to 36,998 ft asl in 19 minutes, covering 138 nm, beginning about 1 mile southwest of KIND.

Cruise was level at 37,000 ft asl for 55 minutes, covering 489 nm, starting roughly 2 miles southeast of Bellefontaine (7I7). Descent began from 36,998 ft asl and proceeded to 1,185 ft asl in 20 minutes, covering 121 nm, starting 6 miles east of Cropseyville, with a brief level-off at 9,900 ft asl.

Final approach to Logan International Airport (KBOS) runway 22L started from 1,208 ft agl and descended to 62 ft agl in 91 seconds. Stabilisation checks at 1,000 ft and 500 ft above the runway were all met: gear down, landing flap, sink rate, glideslope, centreline, speed, and wings level. The landing gear was lowered at 2,451 ft agl at 182 kt; final flap position 6 was selected at 2,187 ft agl at 175 kt.

Landing on runway 22L was performed with a good threshold height and a threshold speed of 157 kt. The flare was described as very good, with little round-out. Touchdown occurred 1,301 ft down the runway at 148 kt, a speed judged good, with a touchdown rate of minus 263 fpm, rated fair. Alignment on touchdown and during rollout was perfect. No bounce occurred. Total landing distance was 5,980 ft, which is 66 % of the runway, and the rollout alignment remained perfect.

Local weather at KBOS was 45 °F with a wind of 3 kt from 200°, a 0 kt crosswind and a 3 kt headwind. After landing, the aircraft taxied to parking in 4 minutes, covering less than 1 nm.

The flight covered 756 nm in 105 minutes and consumed 29,731 lb of fuel.
