Latest bit of legislation by Instrument
This instrument permits an aircraft with a maximum take-off weight of more than 5 700 kg that is engaged in regular public transport operations to take off with residual traces of snow, frost and ice. The exemption is subject to conditions directed by CASA in the interest of safety, including that the pilot in command must ensure that appropriate procedures have been used and be satisfied that any residual traces of snow, frost or ice will not affect the performance of the aircraft.
How does a PIC be satisfied "that any residual traces of snow, frost or ice will not affect the performance of the aircraft" on aircraft like a Dash 8?
