Pattern A320 - Sierra
Do attempt to fly a continuous idle descent. You must actively manage the level segment.

The Sierra Pattern is a standardized, closed-loop flight profile used primarily in advanced flight simulators. It combines multiple flight phases—takeoff, precision turns, clean and dirty configurations, acceleration, deceleration, and approach—into a single, compact exercise.
Encourages pilots to anticipate, rather than react to, aircraft behavior. Conclusion 000 feet above ground level (AGL)
By the time Leo finishes "Sierra Four," he isn't just flying the computer; he is flying the airplane. The Sierra Pattern ensures that when things go "non-normal," the pilot's basic flying skills are as sharp as the aircraft's technology. specific pitch and power settings used for these different training phases?
By 1,000 feet above ground level (AGL), the aircraft must be fully configured, on the correct lateral and vertical path, with engines spooled up. 6. Go-Around or Landing
Practicing these fixed pitch/thrust patterns is vital for situations where flight instruments (like airspeed indicators) fail, allowing the pilot to keep the plane safe using known "by-the-book" power settings Procedural Discipline:
Even though the Sierra Pattern is a visual maneuver, pilots heavily utilize the A320’s Flight Management Guidance System (FMGS) for situational awareness. Pilots will program the visual anchors into the MCDU. They often create a "Place/Bearing/Distance" waypoint from the runway threshold to serve as a digital guide for Point Sierra. The autopilot and flight directors are used during the initial transition, but the final quadrant of the pattern is flown manually. Flying the Downwind Leg
