Environmental factors can affect flight safety. Pilots can plan and prepare for some of these conditions.
You can work out the beginning or end of daylight using the graphs on our visual flight rules website.
Visual night flying
There are higher safety risks and additional requirements for visual flight rules operations (NVFR) at night. You can find more information on our visual flight rules website.
Weather can be unpredictable. We have information about different flying operations that will help you calculate the right amount of fuel for the meteorological conditions in case of a forced diversion. You can find more information on our visual flight rules website as well at CASABriefing.
In-flight turbulence is the leading cause of injuries to passengers and crew and can happen without warning. You can find more information on our turbulence page and other safety information from the Australian Transport Safety Bureau.
Volcanic ash clouds have always been a factor to consider when planning flights. We work with international organisations such as the International Civil Aviation Organization to help develop global aviation policies and procedures for dealing with volcanic ash clouds. You can read our case study for more information.
