Full-flight simulators cannot accurately model the windmilling drag and restart envelope above FL250. Most sims cap engine failure scenarios at 20,000 feet.
Although specifically named routines may vary slightly between operators, Sierra Pattern training typically includes:
There are two main ways to execute a circuit, both building pilot proficiency in different ways:
Enhance understanding of required pitch and thrust settings. sierra pattern a320
As the aircraft flies parallel to the runway and comes abeam of the landing threshold, the Pilot Monitoring (PM) starts a chronometer . In zero-wind conditions, the aircraft must fly outbound for exactly 45 to 48 seconds before turning base. This provides a standardized geometric footprint for the final approach. 4. Turning Base and the Final Descent
If you are looking to sharpen your stick-and-rudder skills or prepare for an airline sim assessment, here is everything you need to know about the Sierra Pattern. What is the Sierra Pattern?
Imagine a racetrack in the sky:
Ideal lateral displacement from the runway is roughly 2.5 nautical miles . Crews often use the "Fix Info" page in the MCDU to draw a 2.5 NM radius circle or extended runway lines on their ND for spatial awareness.
In the MCDU (Multipurpose Control and Display Unit), the vertical revision page for the affected waypoint will show a symbol (S) next to the altitude constraint, indicating a "Hard" or "Step" constraint requiring a level segment.
The goal is singular:
Airline standard operating procedures (SOPs) mandate that an aircraft must be fully stabilized by 500 feet above ground level (AGL) in visual conditions. This means the aircraft must be: On the correct flight path. In the final landing configuration. VAPPcap V sub cap A cap P cap P end-sub (-5 knots to +10 knots). Operating at a steady engine spool-up state.
