Final answer:
Life rafts are required for a multi-engine aircraft that can maintain flight with a single engine typically when flying over water, with specific regulations depending on the distance from shore. Requires verification with current aviation regulations.
Step-by-step explanation:
When life rafts are required for a multi-engine aircraft that is capable of maintaining flight with a single engine depends on the specific operating regulations of the country and the type of operations the aircraft is conducting. Typically, life rafts are mandated:
- When flying over water - This applies when flights are conducted beyond a certain distance from shore, as dictated by aviation regulations, to ensure safety in case of an emergency landing over water.
In other scenarios such as flights over mountainous terrain, during night flights, or at all times, life rafts might not be specifically required unless stipulated by the operator's flight operations manual or by additional regulations for specific regions or types of flights. Standard flight safety equipment requirements vary by jurisdiction and should always be verified with current regulations.
