The NAP lists the preferred flight paths as:
2.1 Minimum heights over densely populated areas (unless in the course of taking off or landing)
- Jet aircraft: 5,000 ft
- Non-jet aircraft: 3,000 ft
Note: This NAP is under review to determine how it can be reported.
2.2 Departures
- Use standard departure paths (SIDs).
- If not, fly as close as possible to those paths and follow height rules.
Adherence with this procedure is reported below. SID operations are reported up to 10,000ft adherence.
We are continuing to refine our reporting on this NAP. It notes the need to “approximate” the SID where the procedural SID is not being flown. We are working to define an appropriate corridor that aircraft should be within in this case. In the meantime, reporting is provided using the SID corridor only without any variance for approximation. As such adherence numbers will appear lower than actual results. We expect to be able to better define this in next month’s reporting

2.3 Arrivals
- Use standard arrival paths (STARs) where available.
- Radar vectors allowed.
Adherence with this procedure is reported below.
- Radar Vectoring – Air traffic controllers can sometimes guide a plane off the STAR route and give it specific headings (or “vector”) using radar to help it join the final runway-aligned landing path. Controllers do this to keep safe spacing between planes, manage traffic flow, and make the landing process more efficient.
We are continuing to refine our reporting on this NAP. It notes aircraft can be vectored at particular points which will take them off the STAR approach. We are working to define these points and the likely corridor aircraft would fly in from there. In the meantime, reporting is provided using the STAR corridor only without any variance for this vectoring. As such adherence numbers will appear lower than actual results. We expect to be able to better define this in next month’s reporting.

2.4 Runway 16 arrivals (arrivals from the north east turning left onto the long north-south runway)
- Use STAR via waypoint BELTA or
- Visual track via waypoint ROKDL with restrictions:
- no shortcutting early
- avoid flying low over Wallan (if not possible, then jet aircraft should be at or above 6000 ft whenever practicable)
Note: A waypoint is a geographical location used to define a point on a flight path. Waypoints are defined by geographic coordinates and typically take the form of a five-letter capitalised word e.g. BELTA, ROKDL, PORTS.
Adherence with this procedure is reported below.

2.5 Runway 34 arrivals (arrivals from the south onto the long runway)
(1) Aircraft turning right to land:
- Use STAR via Essendon Airport, or if needed, may be radar vectored south of Essendon Airport to join the final runway aligned landing path
(2) Aircraft turning left or heading straight-in to land:
- Must follow applicable STAR, or
- between 6am–11pm only, may be radar vectored to join final runway-aligned section no closer than 3.5 Nautical Miles (roughly 6.5km) from touchdown
Adherence with this procedure is reported below.

2.6 Night time arrivals (11pm–6am)
- Southeast arrivals must stay east of the ONAGI–MOSVO line
- Unless landing on Runway 09 or 34 using PORTS STAR
Adherence with this procedure is reported below.

Note: Air Traffic Control may adjust paths for weather and/or traffic conditions.
Standard Instrument Departures (SID) and Standard Instrument Arrivals (STARs) are published flight paths designed to enhance safety, efficiency, and predictability. Air traffic control (ATC) may issue a deviation to a SID or STAR due to weather and/ or traffic conditions.
The report below provides the percentage adherence against the NAP criteria for preferred flight paths. For NAPs 2.2 and 2.3 reporting is available back to January 2025. For NAPs 2.4, 2.5 and 2.6 reporting is available from June 2025. Reporting back to January 2025 is currently being prepared and will be added to this page soon.
“Other Operations” refers to operations where adherence was unable to be determined.
The report is best viewed in full screen mode.
Note: Due to rounding, percentage values may not sum to exactly 100.0%. Minor discrepancies of up to ±1% are expected and do not indicate any errors in the underlying absolute figures, which remain accurate and unaffected.
