What is O/P on Airbus A320? (Output)

The Airbus A320 is a popular narrow-body aircraft widely used by airlines around the world. It is known for its reliability, efficiency, and advanced technology. One important aspect of the Airbus A320 that contributes to its success is its output, which refers to the various systems and components that generate power or information on the aircraft. In this article, we will explore the different outputs on the Airbus A320 and understand their functions and importance in ensuring a safe and smooth flight.

When we talk about output on the Airbus A320, we are referring to both electrical and mechanical outputs. These outputs are essential for the proper functioning of the aircraft and play a crucial role in various systems and operations.

Electrical Outputs on the Airbus A320

The electrical outputs on the Airbus A320 are responsible for powering numerous systems and components on the aircraft. The primary electrical power source comes from the engines, which drive generators to produce electricity. Let’s take a closer look at some of the key electrical outputs:

1. Alternating Current (AC) Electrical Output

The AC electrical output on the Airbus A320 is generated by the engines’ Integrated Drive Generators (IDGs). These IDGs convert mechanical energy from the engine into electrical energy. The AC electrical output powers essential systems such as the cockpit displays, flight controls, lighting, air conditioning, and in-flight entertainment systems.

Furthermore, the AC electrical output is also used to power electrically driven hydraulic pumps, which provide hydraulic power for the aircraft’s various hydraulic systems. These hydraulic systems, such as the landing gear, brakes, and flight controls, rely on the AC electrical output for their operation.

It is crucial to ensure that the AC electrical output remains stable and within specified limits to avoid any disruptions to the aircraft systems. Electrical power management systems and protections are in place to monitor and regulate the AC electrical output.

2. Direct Current (DC) Electrical Output

In addition to the AC electrical output, the Airbus A320 also has a DC electrical output. The DC electrical power is primarily used to power critical systems and components that require a stable and regulated power source. Some of the key systems powered by the DC electrical output include:

– Emergency lighting

– Avionics systems

– Radio communication systems

– Standby instruments

The DC electrical output is generated by transformer rectifier units (TRUs) that convert the AC electrical power into DC electrical power. Similar to the AC electrical output, the DC electrical output is also monitored and regulated to ensure optimal performance and system reliability.

Mechanical Outputs on the Airbus A320

In addition to electrical outputs, the Airbus A320 also has various mechanical outputs that are crucial for the safe and efficient operation of the aircraft. These mechanical outputs range from mechanical forces generated by the engines to mechanical information provided by sensors and instruments. Let’s delve into some of the key mechanical outputs:

1. Thrust Output

Thrust output is one of the most critical mechanical outputs on an aircraft, including the Airbus A320. It refers to the force generated by the engines that propel the aircraft forward. The Airbus A320 is typically equipped with two CFM International CFM56 or Pratt & Whitney PW6000 series engines, which provide thrust to propel the aircraft during takeoff, climb, cruise, descent, and landing.

The thrust output of the engines can be adjusted by the pilots using the engine power levers, allowing them to control the aircraft’s speed and climb rate. The engines’ thrust output is closely monitored by the aircraft’s engine control systems to ensure optimal engine performance and prevent any abnormalities.

2. Sensor Outputs

The Airbus A320 is equipped with various sensors that provide important mechanical outputs in the form of data and information. These sensors are spread throughout the aircraft and monitor various parameters to ensure safe and efficient operation. Some of the key sensor outputs include:

– Air data sensors: These sensors provide data on airspeed, altitude, and outside air temperature. They are crucial for accurate navigation and flight performance.

– Angle of attack sensors: These sensors measure the angle between the aircraft’s wing and the oncoming airflow, providing crucial information for the aircraft’s stall protection and flight control systems.

– Engine sensors: Sensors installed on the engines monitor various parameters such as temperature, pressure, vibration, and rotation speed. This data is essential for monitoring the engine health and detecting any anomalies.

These sensor outputs are continuously monitored by the aircraft’s flight control systems and avionics to ensure the pilots have accurate and reliable information about the aircraft’s status and performance.


The output on the Airbus A320 plays a crucial role in the aircraft’s safe and efficient operation. The electrical outputs, such as AC and DC electrical power, provide the necessary energy to power various systems and components. Meanwhile, the mechanical outputs, such as thrust and sensor data, contribute to the aircraft’s propulsion, control, and monitoring.

Understanding the different outputs on the Airbus A320 is essential for pilots, engineers, and aviation enthusiasts alike. By comprehending these outputs and their functions, we gain a deeper appreciation for the complexity and sophistication of this remarkable aircraft.
