Set up the approach
Tune ISN ILS/DME, 110.1 MHz, with final course 335°. The ILS requires DME or GNSS; a localizer-only approach requires DME. The chart also identifies SY DME, 112.1 MHz. The initial profile altitude is 3,000 ft. SOSIJ is at 12.9 ISN DME / 12.7 NM from the threshold. Follow the 3° glidepath through ATRET, at 5.9 ISN DME / 5.7 NM from the threshold, with a path altitude of 1,900 ft. Reference datum height is 52 ft. Aircraft near taxiway A1 can cause false localizer indications.Speeds and holding
Cross ATRET at no less than 150 kt indicated airspeed. ATC approach speed ranges are 160–185 kt at 10 NM from touchdown and 150–160 kt at ATRET. Hold at SOSIJ with inbound track 335°, left turns, one-minute legs, and a minimum altitude of 3,000 ft. The outbound track shown is 155°. No DME holding limit is printed.Glidepath descent checks
These are altitudes on the 3° ILS glidepath, referenced to ISN DME.Localizer-only descent
Observe these minimum altitudes until reaching each step-down point. They are separate from the glidepath check values.
After the last step-down point, observe the localizer minimum descent altitude below. The localizer missed approach point is 0.4 ISN DME.
The missed approach point is 0.2 NM before the threshold. The profile prints 9 ISN DME / 7.8 NM to threshold for the first localizer step-down point; this pair differs from the 0.2 NM offset at the other labelled points. The controlling step-down reference above is the printed 9 ISN DME.
Straight-in minima
These minima apply to categories A, B, C and D/DL. Runway visual range (RVR) is in metres.Missed approach
Track 335°. At 500 ft, turn left onto track 320°. Climb to 3,000 ft, or as directed by ATC.Parallel approaches
Sydney has closely spaced parallel runways. Simultaneous approaches are authorized with runway 34R under the precision runway monitoring instructions. Dual VHF communications are required during PRM operations. Transmit on tower and monitor both tower and PRM frequencies listed below. Aircraft may be radar vectored to final approach.Circling and alternate minima
Do not circle beyond 3 DME from SY, east of runway 16R and north of runway 25. This restriction uses SY DME, not the approach DME reference.
The chart also prints a special alternate minimum of 700 ft / 2.5 km.
