Study Notes

Life Raft and Lifecraft Equipment Study Notes

Life Raft Deployment: Life rafts are stowed in dedicated compartments near emergency exits on aircraft (e.g., Boeing 737-800). The number of life rafts depends on the aircraft's maximum seating capacity.
Life Jackets: Passengers are provided double-chamber life jackets. These jackets can be inflated by pulling red toggles or blowing into the inflation tube. Infant life jackets have extra straps to prevent sliding off the child's head, securing it to the body.
Life Raft Floatation Time: Life rafts provide flotation for approximately 8 hours.
Hydrostatic Release Unit (HRU): This unit automatically releases the life raft from the aircraft when submerged below a certain depth, allowing it to float freely.
Life Raft Entry Procedures: Passengers should carefully enter the life raft one at a time.
Emergency Locator Transmitter (ELT): ELT's primary function is to send distress signals to search and rescue teams. It's recommended to activate the ELT once the life raft is inflated and passengers are safely onboard. Premature activation can trigger false alarms.
Passenger Evacuation Aids:
- Escape Slides: Attached to the aircraft for passenger evacuation in a water emergency.
- Life Lines: Can be attached to aircraft wings to help passengers move from the aircraft to the rafts. Passengers are to use these lines to maintain control and prevent injury while evacuating to the life rafts.
- Passenger Seat Cushions: Can be used as makeshift floating devices.
- Additional Flotation: Cabin crew are to detach and use the overhead luggage as additional flotation aids.
Cabin Crew Actions:
- Door Issues (Ditching): If water enters the cabin near an exit, cabin crew should mark the exit unusable with an "X", redirecting passengers to other exits.
- Life Raft and Slide Preparation: Cabin crew should prepare the life rafts for use before ditching.
- Emergency Response: Cabin crew are responsible for procedures like slide detachments based on specific regulations.
Other Important Points:
- Life Raft Survival Kits: The supplied text does not give details of the items within a survival kit like signalling mirrors, first-aid kits or desalination tablets. However, other emergency supplies may be present.
