And another scenario re this proposed MULTICOM below 3000ft or 2000ft AGL:
IFR single VHF inbound from western Victoria to Moorabbin, intending to proceed OCTA below the CTA steps via PTOM.
- What frequency should be set from 20 DME ML where the CTA step is C LL 2500?
- if MULTICOM, what does the pilot do re SAR whilst out of comms with ATC?
- if the IFR is on MULTICOM, how should ATC manage SAR & SIS?
Indeed the same scenario will apply to IFR inbound to YSBK from the west proceeding OCTA.
