Sierra Pattern — A320

While the Sierra Pattern can be flown with Auto-Thrust engaged, training captains often require pilots to fly it with manual thrust. This exposes the pilot to the specific percentage of N1 (engine fan speed) required to maintain level flight, a climb, or a descent at various flap settings. Anatomy of a Standard Sierra Pattern Profile

: Focuses on flying the "bird" (Flight Path Vector) rather than following automated flight director bars Target Values : Pilots must memorize and apply specific Pitch and Thrust

Most A320 pilots are taught: "Dual engine failure? Start the APU immediately."

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 (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? While the Sierra Pattern can be flown with

The name is often associated with "S-patterns" or specific maneuver profiles used in flight schools like Sierra Academy of Aeronautics

The pattern typically rounds out into a standard visual traffic pattern or an immediate visual approach to a runway. The pilot tracks the extended centerline or downwind vectors entirely via visual references outside the window and raw navigation data on the Navigation Display (ND). The Airbus Philosophy: Manual Flying Challenges Most A320 pilots are taught: "Dual engine failure

The for the Airbus A320 is a specialized flight training maneuver designed to build a pilot's proficiency in manual aircraft handling, particularly during instrument flight and visual transitions. Often found in airline training syllabi or type rating courses, it requires pilots to fly specific sequences of climbs, descents, and turns without the aid of flight directors (FDs) or autopilots. What is the Sierra Pattern?

The aircraft establishes straight-and-level flight at a baseline altitude and a specific target speed—typically Green Dot speed or a standard clean holding speed (e.g., 210 knots). The pilot stabilizes the aircraft, ensuring the Flight Director (FD) bars are perfectly centered. Phase 2: The Deceleration and Configuration Step

The pattern is defined by three parameters:

Upon reaching Point Sierra, the Pilot Flying (PF) typically disconnects the autopilot to hand-fly the aircraft, though they may leave the auto-thrust engaged to manage speed. The pilot maintains visual contact with the runway environment. Wind correction is vital here; a strong crosswind can blow the A320 too close to the runway or drift it into restricted terrain.
