Answer
Every aircraft is designed for reliability by having redundant systems and computers that monitor the systems.
For example, there are three separate hydraulic systems and the critical controls are powered by two different ones just in case one fails.
The engine is designed and maintained to ensure it is reliable to fly across the ocean without failure.
There are many safety feature designed into the Airbus. I don't know of one that is unique to just the Airbus.
Airbus do not make an A320-300.
It is the model of the plane.
The Airbus A330-300 has an empty operating weight of 124,500 kg (274,500 lb).
The ICAO aircraft type designator code for an Airbus A330-300 is A333
Qantas Airlines currently has 31 Airbus airplanes. Airbus A380-800:12 Airbus A330-300:10 Airbus A330-200:9
Airbus A340-300 has 295 seats Airbus A340-500 has 313 seats Airbus A340-600 has 380 seats
Airbus 330-300 carries 440 passengers.
An Airbus A330-300 has a maximum take off weight of 235 tons or 235,000 kg (520,000 lb)
Airbus Corporation started in the early 1070's. It was about 2 years before the first Airbus 300 flew.
Not different from non-Airbus planes as the safety standards are set by aviation authorities (FAA in the US). If you do not have their minimal safety equipment, you cannot fly.
