An approach may be successfully executed from any position prior to which point?

• A. Runway
• B. Transition Point
• C. Parking Spot
• D. Final Approach

Answer: (B)

The concept here is how you join an instrument approach from the en route environment. The transition point marks the boundary where you switch from the en route structure into the published approach segments. You can initiate the approach from any position before you reach that transition point because you’re still in the phase where you’re joining the approach path and aligning with the published transition/initial segments. Once you’ve passed the transition point, you’re effectively onto the approach itself, and starting from an arbitrary position beyond that point isn’t appropriate; you’d need to already be on a valid transition or part of the published procedure to continue. That’s why the correct choice is the transition point. A runway is the final destination, not a joining point; a parking spot isn’t relevant to procedure entry; and the final approach is a segment, not a boundary for where you may start the approach.
