Airplanes are the safest means of flying, but sometimes some untoward incidents can happen, such as engine failure. In such a situation, RAT i.e. Ram Air Turbine plays an important role and helps in saving lives.

What is RAT?

RAT stands for Ram Air Turbine. It is a small turbine which is installed outside the aeroplane. When the engine fails, the RAT rotates with air flow and generates electricity. This electricity is used to run important parts of the aircraft, such as hydraulic systems, landing gear, and instruments, etc.

How does RAT work?

RAT is installed in the wing or tail part of the plane. When the engine fails, the RAT is activated. It is connected to a hydraulic pump or electric generator. It is like a pinwheel. In case of emergency, this technology comes in handy to save people's lives. Due to this, very important systems of the plane like navigation, flight instrumentation, communication system and flight control system run. When all else fails, the RAT is activated by a pushbutton located in the pilot's electrical panel.

Advantages of RAT:

• The RAT provides power to critical systems in the event of engine failure.
• This helps the pilot to make a safe landing.
• It plays an important role in saving the lives of passengers.

Disadvantages of RAT:

• RAT is not very powerful.
• It can provide power only for a short period of time.
• RATs are expensive to deploy and maintain.

Some examples of RAT:

• In 1983, Air Canada Flight 143's engines failed. RAT helped the pilot make a safe landing.
• In 2009, both engines of US Airways Flight 1549 were damaged by a bird strike. The RAT helped the pilot land safely in the Hudson River.

RAT is an important technology that plays an important role in making airplane flight safe. It provides power to critical systems even in case of engine failure and helps the pilot make a safe landing. RAT plays an important role in saving the lives of passengers.
