When do you begin a side step maneuver in an approach?

Beginning a side step maneuver typically occurs inside the Final Approach Fix (FAF) when the runway is in sight. This timing allows pilots to safely transition from the final approach of one runway to another parallel runway, aligning the aircraft while still maintaining the required altitude and maintaining situational awareness. At this point, the pilot has visual confirmation of the intended runway, which is crucial for executing a safe maneuver.

Executing the side step beyond the FAF means that the pilot is already committed to a specific approach and can make the necessary adjustments for the side step while following the prescribed approach path. This enhances safety as it minimizes the risk of inadvertently deviating from the approach profile before visual confirmation of the target runway.

The other options pertain to different phases or considerations during the approach: the initial approach fix relates to the beginning of the approach, the approach briefing focuses on pre-landing discussions to ensure all procedures and parameters are understood, and minimum altitude is a reference point to ensure safety. However, the actual execution of the side step itself hinges on having the runway in sight, which is why the chosen answer is the most accurate regarding the timing of the side step maneuver.
