Date published: 8 July 2022


Have your say on proposed change to the Part 173 Manual of Standards (MOS) – standards applicable to Instrument Flight Procedure Design.

Have your say

Currently the Part 173 MOS requires that Terminal Instrument Flight Procedures (TIFP) are revalidated by CASA at intervals not exceeding 3 years.

The International Civil Aviation Organization (ICAO) recommends that TIFPs are revalidated at intervals not exceeding 5 years.

We are proposing to make a change to the TIFP revalidation interval – from 3 years to not more than 5 years.

Submit your feedback on the proposed change via the Consultation Hub by 22 July 2022.
