The objective of Part 173 is to set standards, specifications, restrictions, and requirements for the issue and exercise of an Instrument Flight Procedure Service Organisation certificate under the Civil Aviation Act 2023.
This includes certification and operating requirements for organisations that provide services for the design and maintenance of instrument flight procedures (including the technical standards for the design of instrument flight procedures).
Part 173 aims to ensure that the design, maintenance, and promulgation of instrument flight procedures intended for use by aircraft operating under instrument flight rules (IFR) in the New Zealand Flight Information Region (NZFIR) meet or exceed the applicable ICAO standards and recommended practices for instrument flight procedures.
The Part does not apply to the design of aircraft performance operating limitations or flight paths for critical engine inoperative emergency procedures.
