operational deviation

operational deviation (OD)

An operational deviation occurs when a controller allows an aircraft to enter an airspace managed by another controller without prior coordination and approval. An operational error occurs when an air traffic controller does not maintain minimum separation requirements between aircraft. An operational deviation is an occurrence where applicable separation minimums, as referenced in the operational error, were maintained, but:
i. Less than the applicable separation minima existed between an aircraft and protected airspace without prior approval.
ii. An aircraft penetrated airspace that was delegated to another position of operation or another facility without prior coordination and approval.
iii. An aircraft penetrated airspace that was delegated to another position of operation of another facility at an altitude or route contrary to the altitude or route requested and approved in direct coordination or as specified in a Letter of Agreement, precoordination, or internal procedure.
iv. An aircraft, vehicle, equipment, or personnel encroached upon a landing area that was delegated to another position of operation without prior coordination and approval.
