Can an aircraft with only two TSO-129 GNSS receivers operate under public transport or charter regulations?

An aircraft equipped solely with two TSO-129 GNSS receivers does not meet the required standards for operating under public transport or charter regulations in Australia. The TSO-129 standard, while suitable for certain types of navigation, does not provide the necessary dual navigation systems that ensure redundancy and reliability required for public transport operations.

Public transport operations mandate that aircraft must have equipment that can provide precise and reliable navigation under IFR conditions. This often includes more advanced navigation systems, such as those complying with TSO-145 or TSO-146, which offer enhanced performance and safety features.

Hence, an aircraft with just two TSO-129 GNSS receivers lacks the necessary navigational capabilities and redundancies needed for safe and compliant operations in public transport or charter services.
