effectiveness of certified Emergency Locator Transmitters (ELT) if a large

While this issue is currently being addressed by ICAO and the international aviation
industry, the Team is of the view that work needs to be expedited in this area to
implement effective changes to enhance aviation safety into the future.
Additionally, a number of issues were identified that could affect the monitoring and
timely initiation of search and rescue of commercial aircraft in Malaysian airspace
by the Air Navigation Services provider. Issues were also identified in the Airline
Operations. They include the following:

• Quick reference for operations control; and
• Emergency locator transmitter effectiveness.
