The FAA also REQUIRES a circling approach for an IPC or type rating. It is "normally" done with all engines operating but many check airmen (and the FAA) want to see one with an engine inop. However, some airlines prohibit circling approaches in heavy jets during normal line operations. Considering the problems involved with a B747 circling at 400 feet, maybe not a bad idea, especially with the younger guys with EFIS (only) experience. The older guys have done this for years.
