However, the "Sierra Pattern" is more than just a pitch attitude. It is a that the aircraft will follow if the pilot engages the second phase of the go-around via the Flight Control Unit (FCU). In essence, it is the escape route.
Moreover, new technologies are making preparation for these simulator sessions more accessible. For example, the app allows pilots to drill memory items and visualize flight path patterns on their mobile devices, helping them arrive at the training center better prepared.
Instead, airlines teach the : 1) RAT deploy (auto), 2) APU start (attempt), 3) Engine master levers (confirm idle). The Sierra Pattern is a "read and do" item from the QRH (Quick Reference Handbook) that appears only if you are above FL 250 and have more than 5 minutes to live.
: Established by 500-1,000 ft AGL with "Sierra" landing pitch (~ 2.5∘2.5 raised to the composed with power ). 4. Critical Safety Rules
: 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
Allows multiple aircraft to stack and land with minimal separation intervals.

For pilots like Leo, the Sierra Pattern is more than just a maneuver; it’s a "mental calculation" exercise. It teaches them the Rules of Thumb for the A320: Pitch + Power = Performance
This is where the pattern differentiates.
Pro Tip: Practice a "Windy Sierra Pattern." Crosswinds can push you off the magenta line. Do not hand-fly aggressively; let the autopilot (if engaged) or FD guide you.
A typical Sierra pattern report includes specific values for the A320 based on its weight and configuration. While these vary by airline SOP (Standard Operating Procedure), the common "Sierra" baseline values are often as follows: Flight Phase Configuration Pitch Angle Thrust (N1/EPR) ~ 15∘15 raised to the composed with power TOGA / FLX Level Flight Clean (Green Dot speed) ~ 5∘5 raised to the composed with power Approach (Downwind) Flaps 1 (S speed) ~ 5∘5 raised to the composed with power ~50-55% N1 Final Approach Flaps FULL / Gear Down ~ 2.5∘2.5 raised to the composed with power ~55-60% N1 3.
