The minimum equipment list (MEL), a document generated and approved by CASA, sets forth the parameters under which a specified aircraft can operate with certain items of equipment inoperative when taking off. It also sets forth a time schedule for the items to be repaired. The MEL is given to the pilot who makes the decision whether or not the aircraft can be flown with the faulty items. Produced pursuant to computer software known as the Generated Minimum Equipment List (GMEL), which contains detailed information on every aircraft, this tool provides CASA with information necessary to assist with its mission.
This equipment gives CASA a means of evaluating the performance of flight crews and their ability to meet the requirements. CASA requires all flight crews to submit documentation, and flight simulators assist crew members in maintaining those standards. The equipment is maintained at locations throughout Australia by Qantas Airways, the Australian air carrier, and other entities, including Boeing Training & Flight Services. CASA issues certificates for flight simulators detailing which aircraft and what functions of that aircraft are approved for training.
Known as ELT, this distress beacon activates upon an aircraft accident, either automatically or manually. Since 1988, most aircraft operating in Australian airspace have been required to carry an ELT. Each ELT must be registered with the Australian Maritime Safety Authority (AMSA), a free service which is crucial for the operation of the ELT. Beginning in 2009, all ELTs must operate on frequencies 406 MHz and 121.5 MHz. This was due to an international decision that 406 MHz would be the standard frequency for ELTs, with 121.5 MHz being the old frequency.
