When the Boeing 787 operates on autopilot, its sophisticated flight control system manages the flaperons to maintain stable flight, particularly during turbulence. The system continuously receives data from various sensors, including airspeed indicators, inertial navigation systems, and accelerometers. When turbulence is detected, the autopilot system automatically adjusts the position... show more

Boeing is researching innovative ways to tackle turbulence, with two new patented systems targeting both detection and airflow control. 🔹 US4258823A – System for Measuring Turbulence Remotely: Uses advanced electromagnetic sensors to detect turbulence ahead, giving pilots early warnings and feeding data into a real-time 3D global turbulence map. 🔹 EP1842081A2 – Inflow Turbulence Control Structure: Simulates real in-flight turbulence on the ground to make engine and airframe testing more realistic. What's the worst turbulence you've ever experienced on a flight?

Airbus Vertical Speed Indicators (VSI) primarily use a blended "baro-inertial" system to display precise vertical speed, combining responsive inertial data from the Inertial Reference System (IRS) with long-term stable barometric pressure data. The inertial signal is used for dynamic maneuvers and air data for stability over time. This hybrid approach provides rapid responsiveness to pitch changes while maintaining accuracy, reducing errors inherent in using either system alone. Local airflow disruptions (such as turbulence or unsteady wind) can momentarily alter the static pressure, causing the VSI to show unsteadiness or oscillations even when the aircraft is on the ground.

Pretty cool! Used in systems like the attitude indicator and inertial navigation, gyroscopes rely on angular momentum to maintain a fixed reference in space. This allows pilots and onboard computers to know the aircraft's orientation pitch, roll, and yaw regardless of external conditions or visibility. From mechanical gyros to modern laser and ring laser systems, they ensure precise navigation and stable flight at all times.

Following the Airbus A320 emergency airworthiness action, everyone will be talking about the ELAC (Elevator Aileron Computer) manufactured by Thales, which caused a sudden pitch-down without pilot input on JetBlue 1230 back in October. So here’s everything you need to know about ELAC. The ELAC System in the Airbus A320: The Brains Behind Pitch and Roll Control At the heart of the sophisticated fly-by-wire flight control system of the Airbus A320 lies the ELAC (Elevator Aileron Computer). This crucial component acts as one of the primary computational units that translate pilot commands into precise movements of the aircraft’s fundamental control surfaces: the elevators and the ailerons. ELAC plays a pivotal role in ensuring the aircraft’s stability and enabling smooth, safe, and efficient flight. What is ELAC? ELAC stands for Elevator Aileron Computer. On the A320, there are two main ELAC computers—ELAC 1 and ELAC 2—which operate together as essential elements of the aircraft’s fly-by-wire architecture. This system relies on electrical signals, rather than traditional mechanical cables, to transmit control inputs from the cockpit to the flight control surfaces. Key Functions of the ELAC System: Elevator Control: The elevators are control surfaces located on the horizontal tailplane of the aircraft. They govern movement around the lateral axis (pitch), determining whether the aircraft ascends or descends. ELAC receives signals from the pilot’s sidestick and translates them into precise commands to move the elevators, achieving the desired pitch attitude. Aileron Control: Ailerons are control surfaces situated on the trailing edge of the wings. They manage movement around the longitudinal axis (roll), controlling the aircraft’s banking to the left or right. The ELAC processes pilot inputs and moves the ailerons to achieve the intended bank angle. Implementing Flight Control Laws: One of ELAC’s most critical responsibilities is enforcing the pre-programmed flight control laws embedded within the Airbus computers. These laws ensure the aircraft responds to pilot commands in a calculated and safe manner, providing protection against maneuvers that could exceed operational limits (such as overspeed or critical angles of attack). Fault Monitoring and Redundancy: The ELAC system includes a high degree of redundancy to ensure safety. If one ELAC computer malfunctions, the other can seamlessly take over. ELAC also continuously monitors the performance of control surfaces and associated systems, issuing warnings to the crew if any anomalies are detected. ELAC 1 and ELAC 2: Distribution and Responsibility ELAC 1: Primarily controls the ailerons and certain elevator functions, especially those relying on the blue hydraulic system. ELAC 2: Primarily controls the elevators and the Trimmable Horizontal Stabilizer (THS), utilizing the green and yellow hydraulic systems.

Indian investigators are set to visit Seattle for Boeing lab testing tied to the Air India Flight 132 incident involving Boeing 787-8 VT-ANX. The aircraft, operating London Heathrow–Bengaluru on Feb. 2, 2026, was grounded after pilots reported the left Fuel Control Switch slipped from “RUN” to “CUTOFF.” Officials want Boeing to prove under controlled testing that the fuel switches cannot move on their own — even under vibration, turbulence, electrical faults, or other extreme conditions. Boeing is expected to demonstrate that the switch will not move unless physically operated by a human. The outcome of the tests could play a major role in determining whether the incident was caused by mechanical failure, external factors, or human interaction.

Airbus 320 ram air turbine (RAT) test The Ram Air Turbine (RAT) on the Airbus A320 is a retractable, wind-driven emergency power source located on the aircraft's belly. In the event of a total primary power loss, it deploys into the airflow to power the Blue Hydraulic System, ensuring pilots can still control critical flight surfaces and land safely. 📹: aerowingsx

In Germany, after more than four years of war in Europe and daily Russian spy drones, the current debate is about who is responsible for countering drones: the police, the army, gardeners, caretakers, or no one. Meanwhile in China: China has developed a new acoustic-optical system for countering UAVs. The Chinese company Beijing Ribri Technology has unveiled an integrated drone defense system. The system operates using a multi-stage algorithm: acoustic sensors detect the sound of an approaching drone, artificial intelligence recognizes and identifies the target, and thermal imaging cameras and laser rangefinders determine the precise coordinates and lock onto the object for continued tracking. Once the object is acquired, the system initiates targeted jamming, causing the drone to lose control and either make a forced landing or crash to the ground.

What Looks Like A Complex Set Of Spinning Parts Is The Core Of How Trucks Convert Engine Power Into Motion. A drivetrain system transfers torque from the engine through the transmission, driveshaft, and differential to the wheels. Each component plays a specific role. The transmission adjusts torque and speed, the driveshaft carries rotational force, and the differential distributes power between wheels while allowing them to rotate at different speeds during turns. Seeing the system in motion reveals how precisely synchronized these components must be to handle heavy loads and maintain efficiency under stress. In Heavy Vehicles, Power Is Only Useful When It Is Controlled.
