Mastering the Sierra Pattern: The Ultimate Guide for A320 Pilots

In the world of flight simulation and professional Airbus operations, the "Sierra Pattern" is often whispered about in training rooms and online forums as the ultimate test of a pilot’s manual handling skills. Specifically designed for the Airbus A320, this maneuver is a complex, high-workload exercise that forces you to step away from the automation and truly fly the "Bus."

If you are looking to sharpen your stick-and-rudder skills or prepare for an airline sim assessment, here is everything you need to know about the Sierra Pattern. What is the Sierra Pattern?

The Sierra Pattern is a standardized flight training maneuver—primarily used in simulator environments—that involves a series of constant-rate climbs, descents, and turns performed in a specific sequence.

While the Airbus A320 is famous for its "Fly-by-Wire" (FBW) logic and "Auto-flight" capabilities, the Sierra Pattern strips those layers back. It is almost always flown in Manual Flight (Autopilot OFF) and often with Auto-thrust OFF, requiring the pilot to manage pitch, bank, and power simultaneously to maintain precise flight parameters. Why Fly It?

In daily line operations, A320 pilots are management experts. However, basic airmanship can degrade when the computer does the heavy lifting. The Sierra Pattern targets:

Pitch/Power Coordination: Understanding the specific power settings required for various flight phases. sierra pattern a320

Scan Technique: Improving the physical scan of the PFD (Primary Flight Display) and ND (Navigation Display).

Turn Anticipation: Managing the lateral and vertical energy of a 70-ton jet. The Anatomy of the A320 Sierra Pattern

While variations exist, a standard Sierra Pattern typically follows this flow: 1. The Setup

Start in a clean configuration at a mid-range altitude (e.g., 5,000 to 10,000 feet). Stabilize at a specific speed—usually 250 knots—and note your "Target Pitch and Power." On the A320, level flight at 250kts usually requires roughly 2.5° pitch up and 55% N1. 2. The Climb and Turn

Initiate a climb (usually 1,000 or 2,000 feet) while simultaneously entering a standard rate turn (usually 15° to 30° of bank).

The Challenge: You must reach your target altitude and your target heading at the exact same moment. 3. The Descent and Reverse Turn Mastering the Sierra Pattern: The Ultimate Guide for

Once leveled off, you immediately transition into a descent back to your starting altitude while reversing the turn.

The Challenge: Managing the "overshoot." In the A320, when you roll out of a turn, the lift vector changes, and the nose will want to rise. You must proactively push to maintain your vertical rate. 4. Configuration Changes

The "Advanced" Sierra Pattern involves dirtying up the aircraft. You may be asked to decelerate to "S" speed, drop Flaps 1, and then Flaps 2, all while maintaining the climb/descent profile. This tests your ability to compensate for the ballooning effect of flaps and the drag of the slats. Tips for Success in the A320 Use the "Bird" (FPV)

If your instructor allows it, switching to the Flight Path Vector (the Bird) makes the Sierra Pattern significantly easier. Instead of chasing pitch attitudes, you simply place the Bird on the desired flight path angle. However, true purists fly it using the "Crosshairs" (Flight Director OFF) to master raw-data flying. Memorize Your Power Settings The A320 is remarkably consistent. Level, Clean, 250kts: ~55% N1 Level, Flaps 1, S-Speed: ~45-48% N1 3-degree Descent: Roughly 5% less than level flight power. Small Corrections

Because of the A320's Neutral Longitudinal Stability, once you set a pitch, the aircraft will hold it (within reason). Avoid "stirring the pot" with the sidestick. Make a small input, release to neutral, and observe the trend. Conclusion

The Sierra Pattern in the A320 isn't just a hurdle to clear during a checkride; it’s a foundational exercise that builds confidence. By mastering the relationship between the sidestick and the thrust levers without the help of the Autopilot, you become a more resilient pilot, ready to handle the aircraft in any law or configuration. ❌ Trap 3: Turning before SRS termination

❌ Trap 3: Turning before SRS termination

• Symptom: Selecting NAV/HDG while below 100’ AGL may cancel GA TRK, but SRS remains – leading to an uncoordinated climb path.
• Fix: Brief "Positive rate, gear up, then delay lateral changes until after acceleration altitude."

Trap 2: Thrust Surprise

• Problem: You hear the engines spool up during the level segment and mistakenly think ATC has changed the constraint.
• Result: You pull altitude or change mode, disrupting the FMS path.
• Fix: Expect thrust increase. That is normal Sierra behavior.

Part 6: ATC and Communication for the Sierra Pattern

The Sierra Pattern is not just a pilot maneuver; it is a contract with Air Traffic Control.

When you call "Going around, Sierra Pattern" (or simply "Go-around" if it's standard procedure), ATC expects specific spacing.

Standard Radio Calls:

• PF: "Go-around, flaps." (Internal)
• PM (Pilot Monitoring): "Go-around thrust set. Positive climb."
• ATC: "Tower, [Callsign], going around, executing Sierra Pattern, Runway 27L."
• ATC Reply: "[Callsign], roger, climb to 1,500, fly the Sierra, report established downwind."

Note: If ATC asks you to "Extend your upwind," do not fly the Sierra. Fly straight. The Sierra Pattern is a closed pattern for immediate re-entry. If the airport is busy, ATC may vector you away for spacing, in which case you discard the Sierra and follow radar vectors.

Conclusion: The Sierra Pattern is a Mindset

The Sierra Pattern A320 procedure is more than a list of heading changes; it is a disciplined mindset. It acknowledges that a go-around is not a failure—it is a planned, trained phase of flight.

For A320 pilots, mastering the Sierra Pattern means respecting the automation, flying a smooth offset climb, and always keeping the runway in sight until you are safely re-sequenced. Whether you are a trainee in a full-motion simulator or a line Captain flying into London City or LaGuardia, the "S" shape should be as instinctive as flaring for landing.

Next time you hear "Go-around, Sierra Pattern," visualize that graceful 'S' on the radar: Straight up, diagonal offset, and parallel return. It is the signature of a professional Airbus pilot.
