Glenn Strkalj provides an overview of the communications aspects involved in the VH-MDX accident. Identification of equipment likely used on the ground and on board the aircraft, the location of the relevant Flight Service transceiver and radio propagation analysis is carried out.

Communications transcripts are overviewed to determine first contact times after the final received radio transmission from VH-MDX of various stations.

An alternative use of the Air Safety Investigation Branch’s Spectrographic Unit’s findings suggests a coarse track direction of VH-MDX.

This document provides solid information and data to conduct flight path analysis with.
