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.
The chart depicts a right-turn hold at ALAXO with inbound track 064°. It does not print a holding altitude or leg time.
Common route to IKUNA
At IKUNA, follow the branch for your cleared runway.
Runway 09
Fly 230 kt IAS from IKUNA, then no more than 185 kt from GUPUG. The chart’s ATC approach-speed range at GUPUG is 160–185 kt.
Turn left at IKUNA and right at AVPIX. From GUPUG, continue via the cleared GLS runway 09 or RNP runway 09 approach.
Runway 34
Fly 230 kt IAS from MEMEG, then no more than 185 kt from AKDEL. The chart’s ATC approach-speed range at 10 NM from touchdown is 160–185 kt.
Turn right at IKUNA, right at DUDAB and left at OBGAL. From AKDEL, continue via the cleared GLS runway 34 or RNP runway 34 approach.
Identify Melbourne runway 34 by its runway threshold identification lights. Essendon Airport is 5 NM south-east of ML.
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.
