Final answer:
When established on track for different types of approaches varies: It can be upon entering the initial approach fix, when passing the final approach fix, upon intercepting the localizer or glide slope or after completing the course reversal.
Step-by-step explanation:
To determine when you are established on track for various types of approaches, it's important to understand the different segments of an instrument approach and the points where you're considered 'established':
- Initial Approach: You are considered established upon entering the initial approach fix (IAF) when you begin to follow the lateral path of the initial approach segment.
- Intermediate Approach: You may be established on track when passing the final approach fix (FAF) or when cleared for the approach and aligned with the intermediate segment of the approach procedure.
- Final Approach: You get established when you have intercepted the localizer or glide slope at the published altitude, typically before the FAF when flying an ILS or LPV approach, or upon glide slope interception even if prior to the FAF.
- Course Reversal: If the approach requires a course reversal (procedure turn or hold-in-lieu-of PT), you are established after you have completed the course reversal and are aligned on the intermediate or final approach course.
Therefore, depending on the approach type and procedure, 'established on track' can correspond to any of these key approach segments or points.
