The primary goal of these patterns is to ensure that a pilot can maintain control of the A320 in such a manner that a successful outcome is never in doubt. Key skills developed include:
To successfully complete a Sierra Pattern in a simulator session, trainees must generally stay within strict tolerances: Usually -10 to +15 knots of the target. Heading: Within +/- 15 degrees. Altitude: Within +/- 300 feet during transitions. Course: Within +/- 5 degrees. Relation to A320 Visual Circuits sierra pattern a320
Can include more complex transitions, such as climbing or descending turns, further challenging the pilot's instrument scan and mental calculation of pitch and thrust. Core Training Objectives The primary goal of these patterns is to
Typically involves a constant-airspeed descent and climb sequence. Pilots must manage thrust and pitch to maintain a specific rate (e.g., 1,000 fpm) while holding a steady heading and speed. Altitude: Within +/- 300 feet during transitions
Improving "stick and rudder" skills by flying with no FDs and often without the Flight Path Vector (the "bird"). Typical Execution Limits
Developing a rapid and effective visual scan across the Primary Flight Display (PFD) and Navigation Display (ND).
Learning the specific pitch attitudes and thrust settings (N1 values) required for various phases of flight, such as level flight at 210 knots versus a 1,000 fpm descent at the same speed.
