Ram Air Turbine (RAT): How the A320 Stays Powered in Emergencies

Deployed Ram Air Turbine on Airbus A320 in flight
Learn how the Ram Air Turbine (RAT) functions as a critical backup system on the Airbus A320 airliner. Discover how it provides emergency hydraulic and electrical power when all else fails. Introduction Imagine you're cruising at 35,000 feet when suddenly both engines flame out. It sounds like a pilot’s worst nightmare, but even in this [...]

Airbus A320 Normal Law Explained: Protections, Logic & Flight Control

A320 Normal Law: How it Works

The Airbus A320 flight control system is built on a fly-by-wire philosophy, where computer-mediated laws govern how pilot inputs are translated into aircraft responses. At the core of this system is “Normal Law“—the standard flight control mode that ensures safe, smooth, and predictable handling under normal conditions. This article explores what Normal Law is, how […]

Airbus A320 Alpha Floor Protection Explained

Alpha Floor Triggered - A.FLOOR Displayed on A320 Flight Mode Annunciator

Alpha Floor protection is a critical feature in the Airbus A320’s flight envelope protection system. It automatically applies TOGA thrust when the aircraft’s angle of attack (AoA) exceeds a threshold that indicates the aircraft is approaching a stall-like condition. This function is active when the aircraft is in Normal Law, from liftoff to 100 feet […]

Airbus A320 Flight Path Vector – FPV (Bird) Explained for Pilots

The APU MASTER SW pushbutton might seem like a simple “on/off” control — but behind that switch lies a complex sequence of events, especially when bleed air is involved. In this guide, we’ll break down the exact shutdown behavior, cool-down timing, and ECB-controlled logic every A320 pilot should understand. What Happens When You Press the […]

Airbus A320 Circling Approach Procedure: Complete Guide Based on FCTM

Diagram of Airbus A320 fuel tank sequence showing flow from inner to center and outer tanks, including transfer logic, slat configuration triggers, and valve activation points.
Introduction Circling approaches aren't just another maneuver—they're a visual segment of an instrument procedure that demands precision, discipline, and sharp situational awareness. When terrain, wind, or runway orientation prevents a straight-in landing, Airbus A320 pilots must rely on the circling approach procedure. This guide walks you through the Airbus FCTM-based circling approach—from setup to final [...]
