During helicopter emergency marshal, emergency holding normally commences at how many miles?

Emergency holding distance for helicopters defines a safe, predictable area around the incident where arriving aircraft can be sequenced without interfering with ground operations or other traffic. Seven miles is chosen because it provides a practical buffer: it keeps the rotorcraft far enough from the on-scene work to avoid disruption and wake effects, while still placing them within a reasonable range for ATC to manage approach, sequencing, and eventual arrival at the landing zone. This distance helps coordinate multiple helicopters and align them with ground responders efficiently. In practice, controllers can adjust if conditions demand, but seven miles serves as the standard baseline for emergency holding.
