If an aircraft is established on the ELP between high key and low key, what should the RDO do if another aircraft calls inbound at the four-mile initial?

When an aircraft is established on the Emergency Landing Pattern (ELP) between high key and low key, safety and procedural adherence are paramount. In this context, if another aircraft calls inbound at the four-mile initial, directing that inbound aircraft to execute a discontinued entry is the appropriate course of action.

This directive is necessary because the aircraft in the ELP has established its landing profile and is actively managing its descent and approach. Allowing the inbound aircraft to continue its approach could create a conflict, as the two aircraft would be on potentially intersecting flight paths, which could lead to a dangerous situation. By instructing the inbound aircraft to discontinue its entry, it ensures that the traffic pattern remains safe and orderly, allowing the aircraft already established on the ELP to complete its landing procedure safely.

This approach reflects standard aviation protocols to maintain separation between aircraft, especially when one is in a critical landing pattern like the ELP. The intent is to protect the aircraft in the ELP by prioritizing its landing sequence and avoiding any possible conflicts with other traffic.
