The instrument balances operational necessity with safety by allowing closer approaches only under strict conditions and government direction. Similarly, agricultural operations sometimes need flexibility on weight limits for operational efficiency, provided safety margins are maintained through CASA-approved limits.\n\nThe instrument also updates references in two other aviation instruments to reflect this new legislation replacing an earlier version (CASA EX92/22)."},"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.
