When using these lanes, pilots must:
• operate under VFR
• conform with the general flight rules regarding terrain clearance, flight over
populous areas, and low level restricted areas;
• operate not higher than the altitude specified as the upper limit in the section being
flown; and
• keep to the right.

CRUISING LEVELS
SELECTION OF LEVELS
All flights must be planned at levels in accordance with the table of Cruising Levels.
VFR flights in Class E or Class G airspace must be operated at levels selected in
accordance with the table of cruising levels above when operating at or above 5,000FT
AMSL, and must be operated at such levels when below 5,000FT AMSL whenever
practicable (CAR 173).
Notwithstanding the above, ATC may be requested to approve flight within controlled
airspace at a level that does not accord with the above and may approve such flight.

CRUISING LEVELS
BLOCK LEVELS
On request from the pilot, a flight may be cleared to operate within controlled airspace
within a Block Level provided that other aircraft are not denied the use of that airspace
contained within that Block.
A glider or balloon cleared to operate in controlled airspace will be assigned block
levels.
The pilot shall have complete freedom to change levels within the block, provided that
the upper and lower levels are not exceeded. However, a clearance to operate within a
Block Level shall be cancelled or amended if another aircraft requests the use of a level
within the block.
When cancelling or amending a Block Level clearance, the aircraft operating in a Block
Level shall be instructed to climb or descend to an appropriate level or block level in
order to provide vertical separation from the other aircraft requesting one of the levels.
Aircraft at standard flight levels will be afforded priority over aircraft using nonstandard
flight levels.
AIR TRAFFIC SERVICES AIRSPACE
Whenever flight rules are changed during the flight (ie. VFR to IFR or IFR to VFR), the
pilot must report to ATS at the time the change takes place.
Pilots of aircraft engaged in parachute operations must make an all stations broadcast
advising their intentions, on the appropriate area VHF, and/or MBZ frequency/CTAF
two (2) minutes prior to parachutists exiting the aircraft. In addition, when operations
are conducted in controlled airspace, a clearance to drop is required. Notification of
clearance request must be made at least five (5) minutes before the proposed exit.
Aircraft may maintain a listening watch on other than the area VHF for operations
below 5,000FT OCTA such as parachuting, gliding, agricultural operations and circuit
training or local flights at non-controlled aerodromes outside a MBZ or CTAF area.
Gliders are encouraged, but not required, to monitor the Area VHF when operating
above 5,000FT OCTA.
LIMITED RADIO AND NO RADIO PROCEDURES
Authorisation may be given to Australian registered aircraft to vary the requirements
for the carriage of radio equipment as specified in Radio Communication and
Navigation Requirements. Authorisations are given by the relevant District Office of the
CASA.

CRUISING LEVELS
A no-radio aircraft operating OCTA may, due to stress of weather, operate above
5,000FT to the minimum extent necessary for the safe conduct of the flight, provided;
• the aircraft cruises at a VFR level;
• the cruise is conducted in VMC; and
• as soon as is practicable, the aircraft descends in VMC to below 5,000 FT to
continue flight in VMC. A pilot not able to comply with these requirements must
proceed to the nearest suitable aerodrome and land.
A no-radio aircraft other than a glider may operate above 5,000FT within the confines
of a published Danger Area. Gliders may be authorised to operate above FL200 and
monitor an approved frequency other than the area VHF frequency. The area of
operation will be advised by NOTAM.
If total or partial failure of mandatory radio communications equipment occurs before
flight commences and repair facilities are available, repairs must be made before the
