Sierra Pattern A320
In a panic, the PF selects Flaps 0 immediately after TO/GA thrust. Fix: The A320 wing needs flaps at low speeds. Do not select Flaps 0 until you see the "L" (Lift) symbol disappear from the speed tape, or until you are at Acceleration Altitude (400 ft AGL). Retracting flaps early causes a sink rate – the last thing you want at 200 feet.
: Establishing a stabilized platform at a set altitude and airspeed (e.g., 250 knots).
Fly safe, fly precise, and fly the Sierra.
, commonly called "the bird," to visually maintain the desired 3° glide path or specific vertical speed during these maneuvers Purpose in Training Manual Flight Skills:
Note: These figures vary slightly depending on gross weight and atmospheric conditions, but serve as the default baseline in A320 Type Rating Mental Calculation Booklets . Step-by-Step Training Execution Guide sierra pattern a320
In an A320, the initial GA pitch target is (or about 10 degrees in the A321, depending on weight). Do not over-rotate. The Flight Director will command a wings-level climb.
The Airbus A320 has specific energy management characteristics that make adherence to a standard pattern crucial.
The Sierra Pattern creates an offset rectangular pattern.
Because of the A320's , 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 In a panic, the PF selects Flaps 0
The Sierra Pattern relies heavily on standardized Crew Resource Management (CRM). The Pilot Flying (PF) calls for the configurations, while the Pilot Monitoring (PM) executes the commands on the central pedestal and verifies the aircraft's response on the Primary Flight Display (PFD).
What of the training booklet or syllabus you are using.
The target pattern altitude is strictly . Flight crews typically limit deviations to a razor-thin window: +/- 10 knots of target airspeed and +/- 100 feet of altitude.
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 Retracting flaps early causes a sink rate –
. The target is to arrest the descent and pass through the bottom altitude exactly as the clock ticks over, establishing a +1,000 fpm climb. Phase 5: Configuration Integration
: Helping pilots learn exactly what pitch angle and thrust percentage are needed to maintain level flight, climb, or descend at specific speeds.
In an A320 training syllabus , you aren't just flying for fun—you're flying for precision. Instructors typically look for the following tolerances: Within +/- 300 feet. Airspeed: Within -10 to +15 knots. Heading: Within +/- 15 degrees. Pro-Tip: The "100-Foot" Rule
