purpose 160 ft per NM is a satisfactory figure. This rate of decent, represented by the full line in Figure 8‑21, extends to the minimum altitude without infringing any of the terrain clearance steps that are represented by the dotted line.

Section 8.4:   Standard Terminal Arrival Routes (STARs)

8.4.1                   STAR Standards

8.4.1.1              Standard Terminal Arrival Routes (STARs) must be designed in accordance with the following standards:

(a)         RNAV systems are not to be used as the primary navigation reference below the en-route Lowest Safe Altitude;

(b)         STAR procedures employing RNAV waypoints must be identified as RNAV procedures on the associated STAR charts;

(c)          STARs should be seamless from the en-route cruise level to:

(i)            the initial fix of an instrument approach; or

(ii)          A fix from which radar vectors to the runway centreline are given; or

(iii)        for domestic flights only, a fix from which a visual approach is given.

(d)         holding patterns must be restricted to one per STAR.

(e)         the minimum crossing angle between STAR and Standard Instrument Departure tracks should be 45°.

Section 8.6:   Helicopter off-shore procedures — airborne radar

8.6.1                   Definitions and abbreviations

 In this section:

 ATP means approach termination point that is for a specialised helicopter operation that is to or from:

(a)         an off-shore installation; or

(b)         a point in space above the surface of the ocean used for operations connected with the off-shore installation.

 CAR 1988 means the Civil Aviation Regulations 1988.

 G/S means ground speed.

 ISA means International Standard Atmosphere.

 low terrain means a coastal land feature, including a structure on a feature, provided that the maximum height of the feature and the structure (if any) does not exceed 500 ft AMSL inclusive of any allowance made for vertical errors.

       Note   Coastal land features include, for example, islets, shoals and cays.

 OIP means offset initial point.

 TAS means true air speed.

 VF means validation fix.

8.6.2                   Application

8.6.2.1              For subparagraph 173.030 (b) (ii) of CASR 1998, except as provided for in paragraph 8.6.6.6, 30 NM is the closest distance from the nearest land to an off shore installation that is applicable in carrying on design work on a TIFP that is:

(a)         permitted by a procedure design authorisation under Part 173 of CASR 1998; and

(b)         for use by Australian aircraft operating under the IFR at or in the vicinity of the installation.

8.6.2.2              The distance mentioned in paragraph 8.6.2.1 may only be used for design work on a TIFP if the requirements of this section are met.

8.6.2.3              The approach criteria for a TIFP provided for in this section represent minimum design standards that must be complied with.
