Sierra Pattern A320 -
When a pilot decides to abort a landing (Go-Around), they press the (Take-Off/Go-Around) switch on the thrust levers. This triggers a pre-programmed sequence: The aircraft automatically changes from Approach Law to Normal Law, the thrust levers advance to the Go-Around detent, and the Flight Director (FD) displays a specific pitch attitude target (usually 15 degrees nose up).
In the world of commercial aviation, precision is paramount. Nowhere is this more critical than during the final phases of flight—approach and landing. For pilots transitioning to the Airbus A320 family, one of the most drilled, debated, and essential maneuvers is the Sierra Pattern A320 . While the term might sound like classified military code, it is actually the cornerstone of the Airbus go-around procedure. sierra pattern a320
If you are an A320 pilot-in-training, a flight simulator enthusiast, or an aviation geek curious about Airbus logic, understanding the Sierra Pattern is non-negotiable. This article dissects what the Sierra Pattern is, why it exists, how to execute it flawlessly, and the common traps that snare even experienced pilots. First, let’s decode the jargon. In Airbus terminology, the "Sierra Pattern" refers to the standard go-around procedure specifically for the A320 family (including A318, A319, A320, and A321). The name derives from the phonetic alphabet letter S (Sierra), which stands for "Standard" or refers to the specific lateral and vertical path coded into the Flight Management and Guidance System (FMGS).

As soon as you engage TO/GA, twist the FCU altitude knob to the higher ATC clearance (e.g., 5000 ft) while still in the low-altitude phase. 3. Premature Flap Retraction The A320 has high drag with Flaps 3. In a heavy jet, retracting flaps to 2 or 1 too early while still at low speed (Vls – lowest selectable speed) can cause a stick shaker or loss of climb performance. Nowhere is this more critical than during the
Muscle memory training. "In a go-around, pull for safety." 2. Ignoring the "ALT*" Transition After the go-around, the A320 will capture the missed approach altitude in ALT* (ALTitude capture) mode. If you don't verify that the FCU altitude has been set to a higher initial level, the aircraft will level off dangerously low.
