13.1 a) Australian helicopter requirements are contained in ERSA FAC for each international aerodrome. Pilots
prefer that this information be included in ERSA FAC.
13.6.1 a) Coordinates are in degrees, minutes and tenths of a minute. CASA requirement.
c) Only RWY end elevations are shown. Geoid undulation data not available.
d) Partial compliance. Type of surface, bearing strengths, displaced thresholds and RWY markings are
contained in ERSA. ERSA is the preferred repository for this data.
h) Not shown on Australian AD charts. Not relevant to Australia.
CHAPTER 15
15.5.2' Magnetic variation to the nearest degree is shown, but not the annual change. Annual change not
considered necessary.
15.6 b) Comply in part - visual guidance docking systems are not shown. Not considered necessary.

17.4.4*
Australian WACs follow the overlap criteria in critical areas of map coverage, but, in general, WAC
coverage ceases at the neat line. Traditional depiction is to the neat line only.
International boundaries are being progressively included on WACs.
Australian WACS do not accord with this recommendation. Not considered necessary.
A warning note is included on WACs. All charts are progressively becoming compliant.
This information is shown in ERSA. Only the aerodrome type, by symbol and its name, are shown. The
ERSA presentation is preferred by pilots.
Prohibited, restricted and danger areas are not shown on WACs. These areas are shown on Enroute Charts
(ERCs) and VNCs in lieu.
Elements of Australia's air traffic services system are not shown on WACs. Not included because of the
prohibitive costs in updating this information.
The VNCs approximate, but are not quarter sheets of the WAC coverage of the same areas. Required
coverage of VTCs makes such a recommendation impracticable.
Recommended overlaps are impracticable.
Australian VNCs do not accord with this recommendation. Not considered necessary.
AD data are not shown on VNCs. These data are shown in ERSA in lieu.

CHAPTER 2
The Area Chart (Annex 4, Chapter 8) is identified as the Terminal Area Chart.
The Aerodrome Ground Movement Chart (Annex 4, Chapter 14) is identified as the TAXI Chart
The Aircraft ParkingiDocking Chart (Annex 4, Chapter 15) is identified as Parking Areas.
2.5.4 Linear dimensions are shown in feet.
2.5.7 A conversion scale (metresifeet) is not provided for each chart on which elevations or altitudes are shown.
2.13 In Canada, restricted, danger and advisory areas apply.
2.18 Remark: Canada uses the North American Datum 1983 (NAD 83) as a geodetic reference datum. NAD 83
is equivalent to the World Geodetic System - 1984 (WSG-84) for aeronautical purposes.
CHAPTER 3
3.3.2 Linear dimensions are shown in feet, but there is no conversion scale to metres.
3.8.2.2 It is not proposed to include such information on the charts at this time. Should an operational
requirement for this information develop in the future, the implementation will be reported prior to
publication.

The Precision Approach Terrain Chart - ICAO is not produced. However, "Terrain Profile View" are
provided on CAT I1 and 111 Instrument Approach Charts.
Area minimum altitudes are not published. However, Geographic Area Sxfe Altitudes (GASA) are used
which provide 2 000 feet of clearance, rounded up to the next higher 100 foot increment, over known
obstacles or terrain within the delineated geographic area. Implementation of AMA is expected by
IS April 2002.
7.9.2 In Canada, restricted, danger and advisory areas apply.
