FAA and #casa use of the AC [Advisory Circular] process

Question is: Do Advisory Circulars improve knowledge or are these documents being used by #casa to “bash GA” as another tool for this purpose.

The easy comparison is the indexing system used by the #FAA, which starts at the Parts [see below, after you scroll through the #casa example], then directs [as a good index system should] to the relevant AC’s.

In the #casa system, all the AC’s are listed [you can do a search] together with no reference to the Parts at all [see below]. This is, again despite Australia moving towards this system!!

A slow and laborious process.

Let’s use an example – ADSB

Both #casa and #FAA have a single entry.

#FAA – ADSB – AC_90-114A_

#casa ADSB AC-021c45

The #casa version comes in at 33 pages and it’s references [current version – June 2015] lists a cancelled #FAA AC 90-114, with no indication of the replacement [90-114A – Automatic Dependent Surveillance-Broadcast Operations with Change 1 Date Issued October 28, 2014]

The #FAA AC, is at 47 pages, but which show how the system works, rather than what #casa provides which is a separate micro-management version.



Let’s use a simple comparison of the US-FAA Ac for:

and the #casa AC for a similar purpose.

Definitions first:

#FAA –Advisory circular (AC) refers to a type of publication offered by the Federal Aviation Administration (FAA) to provide guidance for compliance with airworthiness regulations. They define acceptable means, but not the only means, of accomplishing or showing compliance with airworthiness regulations.

 

#casa – Advisory Circulars (ACs) provide advice and guidance to explain particular regulatory requirements of the Civil Aviation Safety Regulations 1998 (CASR) or associated Manual of Standards (MOS).

An AC should always be read in conjunction with the referring regulations. It should still be read as guidance material even if referred to in a ‘Note’ below the regulation.


A full list of the #casa current AC’s are below:
