Improve the pattern base leg turn

See Pattern Base Leg Turn

Bank angle in the pattern is conventionally kept to 20 to 30 degrees, and the base-to-final turn is where that convention earns its keep. Stall speed rises with bank because the wing must produce more lift in a turn. Roughly 7 per cent higher at 30 degrees, about 19 per cent at 45, and around 40 per cent at 60. At 65 kt on base you don't have much margin to spend steepening a turn to salvage an overshoot.

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 circuit to KSZL 01

Left-hand, 1,000 ft circuit height. The plan shows your circuit over a textbook one for this runway; the profile unrolls the same path from liftoff to the threshold.

How to read this

The lap from above, with the landing direction to the left: the opposite of the runway drawings. The wide pale-blue line is a textbook circuit for your downwind speed - the downwind a mile out for every 100 kt, every turn at 30° of bank - and your track is drawn over it, each leg in the colour of its mark. The numbers are the four turns, the same as on the profile and the cards below. The 45° line from the threshold is the usual point to turn onto base.

How to read this

The same lap straightened out, so the height and the bank can be read together. Each shaded stretch is a turn, numbered as on the plan. The green box is circuit height, 1,000 ft, on the downwind. The amber line is 30° of bank, and a turn's steepest bank shows red above 32°. "Turn crosswind from" is the lowest height to start the first turn at.

Rough: the G force varied more than a smooth turn and leg would.

Each lap slightly wider and higher than the last, because you're unconsciously using the previous lap as your reference instead of the runway and the numbers. Invisible lap to lap, unmistakable across ten. This is the failure that only measurement catches, because your memory of lap three is gone by lap eight.

High on downwind: 1,325 ft against 1,000 ft, 325 ft above.

Downwind. Parallel to the runway, opposite the landing direction, at pattern altitude and roughly 90 kt. The single most important moment of the entire circuit is the point abeam your intended touchdown point. Power back (around 1,700 RPM in a 172 works as a starting value to calibrate), first stage of flap, pre-landing flow, and re-trim. Everything from abeam to touchdown is one continuous energy problem. Arrive at the abeam point high or fast and you'll pay for it ninety seconds later in the flare, which is why analysing only the touchdown so often misdiagnoses the fault.

Rough: the G force varied more than a smooth turn and leg would.

Bank angle in the pattern is conventionally kept to 20 to 30 degrees, and the base-to-final turn is where that convention earns its keep. Stall speed rises with bank because the wing must produce more lift in a turn. Roughly 7 per cent higher at 30 degrees, about 19 per cent at 45, and around 40 per cent at 60. At 65 kt on base you don't have much margin to spend steepening a turn to salvage an overshoot.

The approach to KSZL 01

The final from 4 nm.

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

On the glideslope from 3.5 nm, where the final began, to 0.5 nm, then low to the threshold (up to 80 ft under).

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.

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.

Joined 1,060 ft right of the centreline at 3.5 nm, then inside the band from 0.9 nm to the threshold.

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 32 kt fast at the 1,000 ft gate, closing to 18 at 500 ft and 10 at the threshold.

Fast from 3.5 nm, where the final began, to 2.5 nm (up to +46 kt), then inside the band to 0.7 nm, then fast to the threshold (up to +19 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.

The crosswind

4 kt across from the left, which takes about 2° of crab to hold the centreline at 133 kt. Touched down with 2° of it still on, wings level.

Wind 290° at 5 kt · 1 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 5,403 ft of the approach.

Crossed the threshold at 16 ft, 34 ft below the 50 ft target. Touched down 568 ft in, 432 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 5,403 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.

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 arrow beside the runway is the crosswind, pointing the way the air was moving, so it pushed the aircraft that way.

Flight narrative

The B-2 Spirit aircraft departed from runway 01 at Whiteman Air Force Base, KSZL, with a takeoff distance of 3,149 feet, which is 25% of the runway length. The aircraft lifted off at a speed of 138 knots. The local weather conditions at the time of departure were a temperature of 38 degrees Fahrenheit, with a wind speed of 4 knots from a direction of 290 degrees. This resulted in a crosswind of 4 knots and a headwind of 1 knot.

After takeoff, the aircraft entered a left-hand pattern, which it completed in a short distance of less than 1 nautical mile in 9 seconds. The aircraft then turned onto the downwind leg, which was 2 nautical miles long and at an angle of 45 degrees to the runway. The downwind leg took 45 seconds to complete, covering a distance of 3 nautical miles. The aircraft then turned onto the base leg, which was also 3 nautical miles long and at an angle of 45 degrees to the runway. The base leg turn was completed with a very small angle to the runway, indicating a precise turn.

The aircraft then began its final approach to runway 01, flying from the south at a heading of 5.0 degrees and at an altitude of 950 feet above ground level. The aircraft landed on the runway, which was 12,413 feet long, with a threshold speed that was slightly above the target speed of 137 knots. The touchdown distance was good, at 574 feet, and the touchdown speed was also good, at 133 knots. The touchdown rate was firm, at -316 feet per minute.

The aircraft's runway touchdown position was slightly misaligned from the centreline, by 11 feet. The local weather conditions at the time of landing were a temperature of 36 degrees Fahrenheit, with a wind speed of 5 knots from a direction of 290 degrees. This resulted in a crosswind of 5 knots and a headwind of 1 knot. The total landing distance was 5,576 feet, which is 45% of the runway length. The runway rollout alignment was very good.

After landing, the aircraft taxied to the parking area, taking 4 minutes to cover a distance of less than 1 nautical mile. The total flight distance was 12 nautical miles, which was completed in 10 minutes. The aircraft used a total of 2,595 pounds of fuel during the flight.
