A large commercial profile makes the aircraft an easy target if it loiters on a standard civilian glide path. Anatomy of the Sierra Pattern
Assuming both engines have failed, windmill restart attempts (Procedure "A") have failed, and you are above FL 250. sierra pattern a320
Let’s walk through a standard scenario. You are on final approach to Runway 27L. At 100 feet AGL, the tower calls for a go-around due to traffic on the runway. Here is the textbook Sierra Pattern sequence.
: Following the level-off, the pilot must immediately transition to a climb at the same fixed rate. This requires a prompt increase in thrust and a specific pitch-up attitude (e.g., positive 12.5 raised to the composed with power positive 15 raised to the composed with power depending on speed and weight). 3. Key Technical Variables To fly these patterns accurately, pilots utilize Pitch and Thrust Tables Whether you will be flying in
A windmilling engine produces less drag and more rotational energy at higher airspeeds. If you simply glide straight at 220 knots, the N2 (core speed) may drop below 10%, making a restart impossible (the starter can't engage above FL250).
You are on short final into Innsbruck (LOWI) RWY 26. At 200’ RA, you encounter severe windshear. The PNF calls "GO AROUND – TO/GA." Let’s walk through a standard scenario
Initial flight stabilization to establish manual control.
A "Sierra Pattern" is broken down into distinct phases. Here’s a quick guide to the components that make up a single standard circuit:
The Sierra Pattern is a specific, standardized flight profile used by Airbus A320 operators to execute a stabilized, constant-descent non-precision approach. It provides pilots with a highly structured sequence of configuration changes, speed targets, and altitude checks. This step-by-step guide breaks down the mechanics, geometry, and execution of the Sierra Pattern to ensure safe and predictable arrivals. What is the Sierra Pattern?
In the high-stakes world of commercial aviation, few maneuvers are as mentally demanding as the (also known as a Rejected Landing or Balked Landing). For Airbus A320 pilots, one specific procedural framework has risen above the rest to become the industry benchmark for safety and standardization: The Sierra Pattern .
