Answer:
during takeoff and landing, and while en route.
Explanation:
Safety belts are required to be properly secured around all occupants of an aircraft during takeoff, landing, and turbulent conditions. This includes both passengers and crew members.
The Federal Aviation Administration (FAA) regulations mandate that passengers must be briefed on the use of safety belts prior to takeoff and landing. The briefing should include instructions on how to properly fasten and unfasten the belt, as well as the importance of keeping it securely fastened during the entire flight.
In addition to safety belts, some aircraft may also be equipped with shoulder harnesses or other restraint systems. These may be required for certain types of aircraft or for certain phases of flight, such as during takeoff and landing. The specific requirements for safety restraints will vary depending on the type of aircraft and the applicable regulations. However, the primary goal of all safety restraint systems is to keep occupants safe and secure during the flight.
