• Lighter Weight: Composites are significantly lighter than aluminum, which improves fuel efficiency and reduces emissions. This also indirectly enhances safety by reducing stress on the aircraft's structure.
• Corrosion Resistance: Unlike aluminum, composites don't corrode, which reduces the need for frequent inspections and maintenance. This helps maintain the structural integrity of the aircraft over its lifespan.
• Fatigue Resistance: Composites are more resistant to fatigue cracking than aluminum, which means they can withstand more stress cycles before developing cracks. This improves the overall durability and safety of the aircraft.

Advanced Avionics

Both the 787 and A350 are equipped with state-of-the-art avionics systems that provide pilots with enhanced situational awareness and control. These systems include:

• Fly-by-Wire Technology: This system replaces traditional mechanical controls with electronic signals, which improves precision and reduces pilot workload. It also allows for flight envelope protection, which prevents the aircraft from exceeding its safe operating limits.
• Enhanced Vision Systems: These systems use infrared cameras and other sensors to provide pilots with a clear view of the runway, even in low-visibility conditions. This improves safety during takeoff and landing.
• Automatic Dependent Surveillance-Broadcast (ADS-B): This technology allows the aircraft to broadcast its position, altitude, and speed to air traffic control and other aircraft, which improves situational awareness and reduces the risk of collisions.

Engine Technology

Both the 787 and A350 are powered by advanced, fuel-efficient engines that are designed to be highly reliable. These engines incorporate several safety features:

• Full Authority Digital Engine Control (FADEC): This system automatically controls engine parameters to optimize performance and efficiency while preventing the engine from exceeding its safe operating limits.
• Engine Health Monitoring: This system continuously monitors engine performance and detects potential problems early on, allowing for proactive maintenance and preventing in-flight failures.
• Redundant Systems: Both aircraft have multiple engines and redundant systems to ensure that they can continue to fly safely even if one engine fails.

Cabin Safety

In addition to the technological advancements, both aircraft incorporate a range of features designed to enhance cabin safety:

• Improved Fire Resistance: The cabin interiors are made from fire-resistant materials to slow the spread of fire and provide passengers with more time to evacuate in the event of an emergency.
• Enhanced Emergency Lighting: The aircraft are equipped with bright, long-lasting emergency lighting to guide passengers to the exits in the event of a power failure.
