A Transformer Rectifier Unit (TRU) converts three-phase AC power into regulated DC power. It combines a transformer and a rectifier in one compact component. Most aircraft use 115/200 V, 400 Hz AC. The TRU converts this input into stable 28 V DC for avionics, lighting and essential electronics. As a result, the TRU forms a […]
Over 6,000 Airbus A320 aircraft were suddenly grounded after an airbus software glitch in a critical flight control computer triggered a global A320 recall. According to regulators, intense solar radiation can corrupt data critical to flight control systems, creating a rare but serious software issue in one ELAC standard. The European Union Aviation Safety Agency […]
The Airbus A320 hydraulic system delivers the hydraulic power to heavy load users such as flight controls, landing gear, brakes, and slats/flaps. According to the Airbus A320 FCOM, the aircraft has 3 hydraulic systems — Green, Yellow, and Blue — each operating around 3000 psi of hydraulic pressure. Each system has its own hydraulic reservoir, […]
The A320 braking system provides reliable braking performance, which is essential for any transport-category aircraft. Engineered to deliver predictable, safe stopping on every landing and rejected takeoff, the Airbus A320 braking system utilizes a multi-layered architecture built around carbon brakes, dual hydraulic sources, and an electronic control computer known as the Brake and Steering Control […]
The Airbus A320’s fuel system is designed to do three things very well: store fuel safely, deliver it reliably to the engines and APU, and keep the aircraft’s balance within limits with minimal pilot workload. This article walks through the practical operation of the system—tank layout, normal engine feed, automatic fuel transfer, and crossfeed usage—then […]
This guide will help you comprehend the importance of maintaining optimal cabin pressure, ensuring a safe and comfortable flight experience. ECAM (Electronic Centralized Aircraft Monitoring) plays a vital role in displaying cabin pressure warnings. When a pressurization warning occurs, it indicates a potential issue with the outflow valve or other pressurization components. Flight crew must respond […]
The A320 pressurization system is a critical component that ensures a safe and comfortable cabin environment for passengers and crew. This advanced system operates in two primary modes: manual and automatic. In automatic mode, the system schedules and commands the outflow valve using FMGS and flight-phase inputs (not altitude alone), allowing for optimal cabin pressure […]
The A320 ice protection system combines pneumatic anti-ice, electrical heating, and ECAM monitoring to keep critical components ice-free and flight data reliable in visible moisture and low temperatures. This system ensures the unrestricted operation of the aircraft by preventing ice accumulation on various areas of the aircraft. Ice formation can significantly affect aircraft performance, making the […]
Why Pressurization Matters In modern airliners like the Airbus A320, maintaining a safe and comfortable cabin environment is essential at cruise altitudes above 30,000 ft. At these heights, ambient pressure and oxygen levels are far too low for passengers and crew. The A320 pressurization system automatically controls the cabin altitude, rate of change, and differential […]
Delays to Airbus’s A220 assembly schedule reflect major supply chain challenges as global parts shortages and shortages in critical materials and delayed parts deliveries force a production pushback; Airbus says the adjustment protects quality and operational consistency and aims to limit disruption across its global assembly network while signaling persistent strain on the aviation manufacturing […]
