Did you know..? During the ultimate load test for aircraft wings, like the B787, engineers subject the wings to extreme forces to ensure they can withstand the most severe conditions in flight. This test involves bending the wings to their limits to assess the strength of the main spar, which is crucial for maintaining structural integrity and ensuring the safety and reliability of the aircraft. A main spar failure during this test could result in certification issues, increased fatigue and load monitoring, and higher maintenance costs throughout the aircraft's lifespan. This verification process is essential for demonstrating the wings' capability to endure extreme forces and certify their operational safety.

On a B787 aircraft, if there is a total Fly-By-Wire failure, how many electrical spoilers can be commanded by the crew, and how is this achieved? NOTE On the B787, if the electrical spoiler fails during testing and is deactivated, consider the following scenarios: 1, No Shear-Out of the Elector-Mechanical Actuator: Install the actuator motor brake cap in the reverse direction. 2,Shear-Out Condition: Install the spoiler lockout tool and the actuator motor brake cap. 3,Manual Drive Port Damaged: The aircraft is no-go (not airworthy). After performing physical deactivation, always go to the special function and perform the SPOILER DEACTIVATION CONFIRMATION.

EASA just posted regulations for HMI appropriate for the mission (SORA OSO#19/#20 low robustness airworthiness requirements) I think this is a critical issue addressed and would lead the industry to a higher standard. https://lnkd.in/eYudgmWs

Attention Getting Box - Mod 169695 Applicability: A320 family In order to improve flight crew awareness in the case of engine failure or engine starting, an Attention Getting Box is added on the Engine & Warning Display and on the System Display ENGINE page. The Attention Getting Box is displayed in white when an engine is starting or in amber when an engine is failed. The Attention Getting Box surrounds the affected engine, like on the figure below:

Excellent to see that EASA has finished addressing the comments against the proposed means of compliance with Light-UAS.2510 and issued a final document taking into account feedback from the industry! The updated text very importantly allows a quantitative assessment of hazardous failure conditions where a qualitative demonstration of no single point of failure could not be demonstrated. This ensures that architectures such as helicopters have a path to Design Verification at SAIL IV. https://lnkd.in/d26V24px

Throwback Thursday! An article on lead-free electronic parts in aviation and ARINC A671 Standard: Guidance for the transition to lead-free soldering, maintenance, and repair. https://lnkd.in/gvK2kgbU #aviation #avionics

Led free soldering? This is the way to transit to led free soldering.

Emergency Use of Transponder Codes In the event of an emergency, pilots should transmit the following codes appropriate to their status: EMERGENCY - Mode 3A Code 7700 (except that aircraft already receiving an air traffic service and transmitting a code normally retain the code in use - see discussion below) COMMS FAILURE - Mode 3A Code 7600 UNLAWFUL INTERFERENCE - Mode 3A Code 7500 Discussion Aircraft already receiving an air traffic service, and transmitting a code, should retain the code in use. Aircraft in an emergency, who are not receiving an air traffic service should set the transponder to EMERGENCY (Mode 3A Code 7700) as part of their initial actions. "A pilot may select Mode 3A Code 7700 whenever he has specific reason to believe that this would be the best course of action" [ ICAO Doc 8168 Vol 1.]

EASA's emphasis on Electrical Wiring Interconnection Systems (EWIS) stems from multiple aviation incidents that exposed the dangers of electrical malfunctions causing in-flight smoke and fire. These events emphasized the necessity for stringent maintenance protocols and enhanced training to prevent similar occurrences in the future. ⚡ Interested to learn more about this topic?
