TCAS Demystified – How Collision Avoidance Works Without GPS
Aircraft Surveillance In Part 1 of our surveillance series, we looked into why classic Mode S transport aircraft do not broadcast their own GPS coordinates, and how ground networks rely on multilateration (MLAT) to figure out where they are. That brings up a natural question for avionics engineers, technicians, and flight crews alike: If an […]
How the Airbus H135 Main Transmission Works
Two engines, one main rotor, one Fenestron, hydraulic pumps and oil-cooling fans all need mechanical power. Sitting at the centre of this arrangement is one of the most important components on the H135: the main transmission. It does considerably more than simply reduce engine speed. The main rotor drive transmits power from both engines to […]
Inside the Airbus H135 Bearingless Main Rotor
Look at the rotor head of many conventional helicopters and you will find a complex collection of hinges, bearings and mechanical joints that allow each rotor blade to move as it rotates. Look at an Airbus H135 and the arrangement is strikingly different. The H135 uses a four-bladed, bearingless and hingeless main rotor system. Instead […]
How the Airbus H135 Fenestron Works
From an Exposed Tail Rotor to the Fenestron A helicopter’s main rotor produces torque that tends to rotate the fuselage in the opposite direction. On a conventional helicopter, a tail rotor mounted at the end of the tail boom produces the lateral thrust required to counteract this torque and provides control about the yaw axis. […]
Transponders, Surveillance Evolution, and Understanding Flight Tracking Discrepancies
By Trans Global Training Ever reviewed a flight playback on Flightradar24 and seen an aircraft take off into thin air, track parallel to the runway through farm fields, jump in sharp 90-degree steps, or abruptly vanish on short final into a coastal airfield? When flight crews or operations report these anomalies, the immediate question directed […]
Airbus H135: From the Bo 108 to a Modern Light Twin Helicopter
The Airbus H135 can trace its origins back through several decades of German helicopter development. Long before the H135 name appeared, Bölkow and later MBB were developing rotor technology that would eventually influence the aircraft we know today. An important predecessor was the Bo 105, a twin-engine multipurpose helicopter introduced during the 1960s. After around […]
Airbus A220 Inertial Reference System: Ensuring Attitude, Heading, and Position Accuracy
