Approach setup and route
Tune IKN ILS/DME, 109.3 MHz, with final course 335°. GNSS is required.
The initial profile altitude is 2,000 ft. During PRM operations, expect to intercept the localizer before ENDEV at 2,000 ft.
Follow the 3° glidepath; reference datum height is 50 ft. Aircraft lining up can cause false glidepath indications.
Speeds and holding
The ATC approach speed ranges are 160–185 kt at BOBIG and 150–160 kt at OLSOG. On the missed approach, keep indicated airspeed at or below 185 kt until SSYSH. Holding is as directed by ATC.
Descent checks
The following altitudes are on the 3° glidepath, with distances referenced to IKN DME.
Minima and missed-approach gradients
These minima apply to categories A, B, C and D. RA is the radio-altimeter value; DA is barometric decision altitude. Heights are above threshold; runway visual range (RVR) is in metres.
Missed approach
Track direct to SSYST, then turn right, direct to SSYSH. From SSYSH, track 060°. Climb to 4,000 ft, or as directed by ATC. Maintain no more than 185 kt until SSYSH and the climb gradient required for the selected minima.
The profile places SSYST 2 NM beyond the threshold, with 1.8 NM on the IKN DME reference line. SSYSH is the next fix; no distance to it is printed on this sheet.
Authorization and parallel approaches
Special aircrew and aircraft certification is required for these minima. Circling is not available. Sydney has closely spaced parallel runways. Simultaneous approaches are authorized with runway 34L under the precision runway monitoring instructions.
During PRM operations, dual VHF communications are required. Transmit on tower frequency and monitor both tower and PRM; the local PRM guide includes participation, receiver setup and break-out instructions.
Aircraft may be radar vectored to final approach.
Frequencies
All frequencies are MHz.
Terrain and chart conventions
Use QNH. Bearings are magnetic, with 13° east variation. Altitudes and elevations are feet above mean sea level unless identified as radio-altimeter readings or heights. The map scale is 1:500,000. Aerodrome elevation is 21 ft; runway 34R threshold elevation is 13 ft.
The 25 NM minimum sector altitude is 2,700 ft and the 10 NM minimum sector altitude is 2,100 ft, centred on the YSSY aerodrome reference point.
The map labels obstacle and spot elevations of 160, 190, 250, 255, 259, 299, 306, 320, 385, 389, 421, 430, 545, 641, 677, 725, 862, 887, 894 and 1,085 ft. Their geographic placement still requires a complete text description.
