This RNP 1 arrival uses magnetic tracks and distances in nautical miles (NM). Altitudes are feet above mean sea level. Maximum indicated airspeed (IAS) is 250 kt below 10,000 ft, with the additional runway-specific speeds below.
The route tables keep segment minimum altitudes separate from waypoint crossing restrictions. Distances are for each leg.
Common route to TUNKA
Cross ARBEY at or above 8,000 ft. Track 156° for 10 NM to TUNKA; the segment minimum altitude is 4,500 ft. Cross TUNKA between 5,000 and 9,000 ft, then follow the branch for your cleared runway.
Runway 09
Fly 230 kt IAS from DABUX, then no more than 185 kt from GUPUG. The chart’s ATC approach-speed range at GUPUG is 160–185 kt.
Turn right at TUNKA, right at DABUX, right at OPAVA and left at UPKAN. From GUPUG, follow the cleared GLS runway 09 or RNP runway 09 approach.
Runway 16
Fly 230 kt IAS from TUNKA, then no more than 185 kt from BELTA. The chart’s ATC approach-speed range at BELTA is 160–185 kt.
From BELTA, follow the cleared GLS runway 16, RNP Z runway 16, ILS-Y/localizer-Y runway 16 or ILS-Z/localizer-Z runway 16. The source specifies RNP Z, not the authorization-required RNP P branch.
Radio failure in instrument conditions
Set transponder code 7600. Comply with the vertical-navigation requirements, but do not descend below the minimum sector altitude. Follow the latest arrival clearance to the nominated runway, then fly the most suitable approach.
Frequencies
All frequencies are MHz.
Sector altitudes and chart conventions
The 10 NM minimum sector altitude (MSA) is 3,300 ft. The 25 NM MSA, centred on the YMML aerodrome reference point, is 4,500 ft in the northern sector and 3,700 ft in the southern sector. The boundaries are labelled B-080° on the west side and B-260° on the east side; these are bearing labels, not VOR radials.
The diagram uses 12° east magnetic variation and is not to scale. YMEN identifies nearby Essendon Airport.
