Cat C,D,E
This trick here is to seperate Instrument Approach to Land criteria (Only one Cat applies), and Visual Approach Criteria. It is easy to confuse.
3.16 VISUAL APPROACHES
3.16.1 Subject to the requirements of visual circling,
missed approach and visual segments paragraphs
above, the pilot need not commence or may
discontinue the approved instrument approach procedure
to that aerodrome when:
a. By Day—Within 30 NM of that aerodrome at an
altitude not below the LSALT/MSA for the route
segment, the appropriate step of the DME or
GPS Arrival Procedure, or the MDA for the procedure
being flown, the aircraft is established:
1. clear of cloud;
2. in sight of ground or water;
3. with a flight visibility not less than 5000m or,
in the case of a helicopter, is able to proceed
under helicopter VMC, or the aerodrome
is in sight; and
4. subsequently can maintain (1), (2) and (3)
at an altitude not less than the minimum
prescribed for VFR flight (CAR 157), to
within the circling area or, in the case of
a helicopter, can subsequently maintain
helicopter VMC to the HLS.
b. By Night— At an altitude not below the LSALT/
MSA for the route segment, the appropriate step
of the DME or GPS Arrival procedure, or the
MDA for the procedure being flown, the aircraft
is established:
1. clear of cloud;
2. in sight of ground or water;
3. with a flight visibility not less than 5000m;
and
4. within the circling area or VAA-H, as applicable;
or
5. within 5 NM (7 NM for a runway equipped
with an ILS) of that aerodrome aligned with
the runway centerline and established not
below “on slope” on the T-VASIS or PAPI;
or
6. within 10 NM (14 NM for runways 16L
and 34L at Sydney Intl) of that aerodrome,
established not below the ILS glide path
with less than full scale azimuth deflection.
NOTE: Reference to circling area in this section
includes the circling area for the category of aircraft
or a higher category where the limitations of the
higher category are complied with.
Avalon only goes to CAT D on the VOR 36 as well.
