Definition
An operations specification (OpSpec) is a formal document issued by the FAA to a certificate holder (such as an air carrier or commercial operator) that authorizes and defines the specific operations that operator may conduct. It lists the approvals, limitations, and conditions under which the operator can fly — including authorized aircraft, routes, airports, navigation systems, instrument approach types, and special procedures. OpSpecs are tailored to each operator and form part of the legal framework governing how that operator may use its certificate.
Plain English
An OpSpec is the FAA-approved rulebook for one specific operator. It spells out exactly what that operator is allowed to do, what equipment they can use, and any conditions they must follow.
Context Anchor
Seen in airline, charter, and other commercial operations, especially when discussing whether an operator is authorized to use equipment or procedures such as an EFB.
Derivation
OpSpec is a shortened form of operations specification. “Operation” comes from a word meaning work or action, and “specification” means a detailed statement of exact requirements. Together, the term means the detailed FAA statement of how an operator may carry out its aviation work.
Why Pilots Care
OpSpecs establish the legal boundaries of what an operator may do, directly affecting flight planning, required equipment, and allowable procedures.
Intuition Check
Do not read “operations specification” as just a company preference or equipment description. In this FAA context, it is an official authorization and set of operating limits for a specific operator.
Example Sentence 1
Before the airline could begin using electronic flight bags in place of paper charts, it had to obtain the appropriate OpSpec authorization from the FAA.
Example Sentence 2
Any change to the OpSpec had to be reviewed and approved by the principal operations inspector before the airline could use it.
