Pacific - ATC Rules and Procedures Flashcards
(16 cards)
When and how are you permitted to descend below the MSA/LSALT?
After crossing the IAF or facility in accordance with the entry and holding procedures, descent permitted to the specified altitude for the commencement of the approach, thence in accordance with the instrument procedure
When are you permitted to commence an approach without entering a holding pattern?
Any airspace using a Navaid:
Reversal entry requirements satisfied, or
DME arc entry requirements satisfied, or
En-route track to the procedure’s commencement fix/facility is
within 30deg either side of the first track of the procedure
GNSS procedure:
Any airspace – tracking to the IAF from within the capture region
and joined using guidance from GPS receiver
Controlled airspace – vectored to intercept the initial approach
segment or direct to the IF (provided track change at the IF does
not exceed 45deg)
Any time in controlled airspace – cleared for the approach (in addition to above)
By night, when are you permitted to discontinue an instrument approach (commence a visual approach)?
Not below the below the LSALT/MSA for route segment, appropriate DME step of GNSS arrival or the MDA of the instrument approach being flown
Currently and can maintain:
Clear of cloud
In sight of ground/water
5000m visibility
Maintain 500ft above the lower limit of CTA
Maintain the route segment MSA/LSALT, appropriate step of the DME/GNSS arrival or last assigned altitude of being radar vectored until:
Within the circling area
5nm – on runway centreline and not below PAPI
7nm – on runway centreline and not below PAPI for runway
equipped with ILS or GLS
10nm – within full scale azimuth deflection and not below
ILS/GLS glide path
14nm – Sydney LEFT runways (16L and 34L) when within full
scale azimuth deflection and not below ILS/GLS glide path
If in controlled airspace – cleared the visual approach
By day, when are you permitted to discontinue an instrument approach (commence a visual approach)?
Within 30nm
Not below the below the LSALT/MSA for route segment, appropriate DME step of GNSS arrival or the MDA of the instrument approach being flown
Currently and can maintain:
Clear of cloud
In sight of ground/water
5000m visibility
Maintain 500ft above lower limit of CTA and not below minimum height above ground as per CASR 91.265
If in controlled airspace – cleared the visual approach
What are the visual approach tracking requirements when within controlled airspace?
On a STAR – continue the lateral tracking of the STAR including and visual or instrument termination route
Not on a STAR – maintain track/heading progressively authorized by ATC until:
BY day – within 5nm of the airport
By night – within the Circling area and with the airport in sight
Then, join the circuit as per ATC instruction
What is the required minimum visibility for partial HIAL or ALS failure when not shown on the chart?
800m – when the ALS normally available beyond 420m from runway threshold is inoperative
1.2km – when the ALS normally available beyond 210m from runway threshold is inoperative
What is the required minimum visibility due to partial failure of runway edge lighting?
1.5x minimum visibility or RVR
Must be controlled airport
Must have interleaved circuitry that results in 120m light spacing rather than 60m
When is descent permitted on a DME/GNSS arrival?
When within the appropriate sector or established on inbound track
When are you no longer permitted to manoeuvre on a DME/GNSS arrival?
After the FAF
What are the implications when cleared for a DME/GNSS arrival?
Clearance for final approach to the minimum altitude specified on the procedure
Once within the circling area – permitted to manoeuvre to align with the runway
Once cleared the arrival, not permitted to hold, orbit or use any holding entry procedures
What are the 3 requirements to use a special alternate minima?
- Local METAR/SPECI and TAF services available
- ATC services active
- Dual ILS/VOR Capability:
Duplicated LOC
Duplicated GP
Duplicated VOR
One of either duplicated DME, duplicated GNSS or single
DME/single GNSS
What is the standard climb gradient on a SID and what gradients are shown on charts?
Standard climb gradient is 3.3% for obstacle clearance
Where gradient is greater than 3.3% it will be annotated on chart, along with where the 3.3% gradient is resumed
A gradient in brackets indicates that required to remain in controlled airspace
What is the capture region for a GNSS instrument approach procedure?
3 IAF
Outer 2 - 90 degree either side
Middle 1 - 70deg either side
2 IAF
Outer 1 - 90 deg either side
Middle 1 - 70deg and 110deg to limiting side
When can you cross the LAHSO hold short lights?
When ATC clear you to cross the intersection – the lights will remain illuminated
What are the recommendations for response to a traffic advisory?
Use all available information to prepare for appropriate action in the event of an RA
Attempt to establish visual contact
Only change flight path if collision risk is established visually
What are the recommendations for a resolution advisory?
Immediately conform to the RA (even if in conflict with ATC instruction)
Limit the alteration to flight path to the minimum required to comply with the RA
Notify ATC where workload permits
