16.4.6* Australian WACS follow the overlap criteria in critical areas of map coverage, but, in general, WAC
coverage ceases at the neat line.

16.7.5 International boundaries are being progressively included on WACS.
16.7.9.3* Highest point spot elevations are not shown cleared of hypsometric tinting.
16.9.2.2 Aerodrome essential data is shown in ERSA FAC. Only the aerodrome type by symbol and its name are
shown on the chart.
16.9.3.1 Australian Rules and Practices for Aerodromes has a requirement under Chapter 10, Obstacles in
Airspace, clause 6.1, "Under regulation 89Y of Civil Aviation Regulation (CAR) 1988 the proponents of
structures in excess of 110 m above ground level to notify the Civil Aviation Safety Authority (CASA)
so that the effect of such proposals to aircraft operations can be assessed."
16.9.4 Prohibited, restricted and danger areas are not shown on WACS.
16.9.5 Elements of Australia's air traffic service system are not shown on WACS.
CHAPTER 17
17.4.4* 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.
17.4.5* Recommended overlaps are impracticabk for Australian coverage.
17.7.9.3* Highest point spot elevations are not shown cleared of hypsomerric tinting.
17.9.2.2 Aerodrome essential data is shown in ERSA FAC. Only the aerodrome type by symbol and its same are
shown on the chart.

18.2* Australia d ~ enso t produce this chart.
CHAPTER 19
19.2* Australia does not produce this chart.
CHAPTER 20 Australia does not produce this chart. The provisions of Chapter 20 are essentially for FMS equipment
manufacturers and data base suppliers. These provisions are, therefore, out of the direct control of those
States that do not have these types of industries. Australia is one of these States.

CHAPTER 1
Instead of the definition "area minimum altitude (AMA)", the definition "minimum safe altitude (MSA)"
is used.
For each aerodrome, the MSA for instrument flight is established, which may be used in descent in
emergency situations when going beyond the limits of the approach procedure, and provides a minimum
vertical clearance of 300 m above the highest point of the terrain and artificial obstacles on it within a
radius of 50 km from the ARP.
If the difference in the altitudes of the terrain, taking into account the artificial obstacles on it, is not
more than 100 m, the MSA is established as being common to the whole terminal area. If there is a
greater difference in the altitudes, the terminal area is divided into sectors and an MSA is established for
each sector.
The altitude of the highest points of the t m i n and the artificial obstacles on it is determined in relation
to the level of the runway threshold in the approach direction and is rounded up to multiples of 10 m.
