Remove six frame bays from the C919-100 fuselage, and COMAC C919-600 is ready, carrying out Taxi and high-speed braking test at Shanghai production facility. The COMAC C919-600 is similar to the Airbus's A319Neo and is the shortened high-altitude "Plateau" variant of China's twin-engine narrow-body jet airliner program, designed to...

Europe is turning up the heat on certifying China’s homegrown C919. According to fresh reports, EASA (European Union Aviation Safety Agency) technicians and pilots are now basically living in Shanghai... conducting near-permanent ground checks and additional flight tests on the COMAC C919 narrowbody. This is the third phase of a four-stage process, which insiders are calling the ‘final exam’... intensive in-flight evaluations followed by deep analysis, paperwork, and technical verification. China isn’t holding back: the CAAC has pulled in top pilots, while COMAC and China Eastern Airlines (the launch operator) are handing over real operational data.... including maintenance records, repair reports, and results from routine A and B checks on the jets already flying domestic routes since 2023. The goal? Maximum transparency to prove the aircraft’s reliability and speed up access to international markets. It’s not just technical. Sources openly note that politics are in the mix too. Getting EASA certification would be a huge symbolic and commercial win for the C919 as it tries to chip away at the long-standing Boeing 737 and Airbus A320 duopoly in the single-aisle market. No official timeline yet for the certificate, but this ramp-up signals real acceleration. Remember, EASA has previously suggested the full validation could still take years... potentially landing somewhere in the 2028–2031 window. The C919 already has strong domestic momentum, but Western approval would open doors for exports and leasing deals that are currently off-limits for most non-Chinese operators.

Rare visuals of a "Tail cone evacuation slide" in action when a Delta Airlines Boeing 717, which departed Atlanta for Columbia, South Carolina, returned back after smoke filled the cabin mid-flight, prompting a safe evacuation. The tail slide on the Boeing 717 got deployed after the rear cone was Jettisoned from the fuselage. Some of the aircraft like MD-83 & B717 have a tail cone emergency exit in the tail cone at the aft end of the passenger cabin. How does tail cone emergency slide work? -If the emergency exits are armed & the handle located in the door of the aft passenger entrance is actuated, the tail cone detaches & the slide deploys automatically. -On actuation, the tail cone releases & falls. It then turns 90° & moves to the left side of the aircraft to keep the tail cone from interfering with the deployment of the slide. -Jettison & slide deploy uses a set of clasps & cables which are attached to a bar on the door & to the clamping bolts on the tail cone. -The tailcone exit may be actuated from two more locations, 👉 A handle on the inside of the tail cone (non-pressurized area). 👉 Another handle on the outside of the aircraft. -The Boeing 717 twin-engine airliner produced by Boeing Commercial Airplanes was developed for the 100-seat market and originally marketed by McDonnell Douglas in the early 1990s as the MD-95 until the company merged with Boeing in August 1997.

Following the Delta A330-323(N813NW) engine failure after departure from São Paulo (GRU), many are asking: what actually happens if an airliner loses an engine just after takeoff? As passenger in the cabin watching this scenario unfold, the panic is understandable. Seeing flames from an engine is alarming. But this is exactly the kind of scenario pilots are trained for repeatedly in simulators. Modern multi-engine aircraft are designed to fly safely on one engine. In fact, losing one engine is a certification requirement during testing. Here’s what happens: At liftoff, pilots target V2 speed—the minimum safe speed that guarantees the aircraft can continue climbing even with one engine inoperative. If an engine fails: • The MASTER FIRE warning light will illuminate in the cockpit and the fire warning bell will sound, alerting the pilots on the affected engine (they will close the fuel, hydraulic shutoff, and engine bleed air valves, and also discharge the related fire bottle to extinguish the engine fire). Of course, they will be careful NOT TO shut down the wrong engine (this has happened before). • Maximum thrust is applied on the remaining engine. • Rudder input keeps the aircraft straight (countering asymmetric thrust) • The aircraft climbs straight ahead for best performance (turns reduce climb rate unless required) Once above a safe altitude (typically ~1,500 ft / Minimum Flap Retraction Altitude(MFRA): • The aircraft accelerates • Flaps are retracted (“cleaning up”) • Crew assesses the situation and plans a return or diversion Even at very low altitude, the aircraft remains controllable by design. It may not climb aggressively, but it will climb. Bottom line: What looks catastrophic from the cabin is a scenario pilots are highly trained to handle—and aircraft are engineered to withstand. Hope this helps any nervous flyer. Flying is safe, and the chances of this happening have reduced due to lessons learned from previous incidents. And if you ever find yourself in this situation, trust that the pilots will act according to their training—because that’s their job.
