RP's should be __ to __ km from the objective, and +/- __ degrees from final landing heading to facilitate a smooth transition from the enroute flight profile to the landing flight profile.

• A. 1-3 km; 60 degrees
• B. 4-6 km; 0 degrees
• C. 3-8 km; 30 degrees
• D. 5-10 km; 15 degrees

Answer: (C)

Transition planning from enroute to landing relies on selecting a reference point that gives you enough time and the right geometry to turn onto final smoothly. Being a few kilometers from the target lets you descend, configure the aircraft (speed, flaps, gear), and set up for the approach without feeling rushed or making abrupt changes in flight path. The distance range of 3 to 8 kilometers provides that balance: far enough to manage energy and transition, but close enough to align with the runway in a controlled way.

The offset from the final approach heading matters because it governs how you join the final path. About 30 degrees offers a gentle intercept angle, which keeps the turn shallow and predictable, helping you fly a stabilized approach as you roll onto final. A sharper turn, like 60 degrees, would require a larger energy change and a more abrupt maneuver, which is harder to manage smoothly. On the other hand, no offset (0 degrees) would mean you’re already on final with limited opportunity to adjust or optimize energy and configuration, and a very small offset (like 15 degrees) doesn’t provide the same comfortable transition as a 30-degree offset.
