Can you compare safety equipment of the A300 with the A380?
Safety equipment should be very similar on all types of commercial aircraft. Each operator can order (or configure, if used) its aircraft as it chooses as long as it meets the safety requirements of its controlling authority. In the US, the FAA sets the minimum safety requirements for each type of aircraft. All aircraft, for instance, would have emergency exits, supplemental oxygen systems, emergency PA systems, emergency lighting, emergency exits, life rafts and other flotation devices, etc. The only difference being that the capacity of each aircraft would dictate the number of pieces of equipment. For instance, the minimum number of life rafts might be one per 50 passengers, so an A380 would have many more life rafts than an A300. But otherwise, all safety equipment is fundamentally the same.
