Operational Readiness & Airport Transfer

EndPoster Video


[ɔːrɑt], abbreviation for Operational Readiness & Airport Transfer

An ORAT is proven to be the most effective process to ensure a successful start of operations of new airport infrastructure.

ORAT is the name of the project / methodology, which helps the future user of the new infrastructure getting ready to operate it. The project brings construction, owner, operator and other users (project internally and externally) together. Its main target is to minimize risks for a successful start of operations and beyond.

A usual ORAT project is dealing with the joint readiness of constructions (facilities and systems), processes and people. It looks after the development and conduction of the Operational Documentation, Testing & Commissioning, Training, Trials and the actual Transfer (activation and relocation).
