VSR700 autonomous take-off and landing capabilities tested at sea
Airbus Helicopters has began sea trials for the VSR700, an unmanned aerial system (UAS) being built for the French Navy as part of the SDAM (Système de drone aérien de la Marine) programme, which is being run by the DGA (Direction générale de l’Armement – the French Armament General Directorate). The trials were carried out with an optionally piloted vehicle (OPV) based on a modified Guimbal Cabri G2 that was fitted with the VSR700’s autonomous take-off and landing (ATOL) technology. This flight test campaign prepares the VSR700 for its impending sea display onboard a French Navy frigate.
The test was carried out in the presence of DGA specialists off the coast of Brest, France, onboard a civilian vessel with a helicopter landing deck. The experiments were meant to examine the approach procedures before landing on the vessel, in addition to showing the ATOL technology built for the VSR700. The VSR700 flight envelope was evaluated at sea, in close proximity to a vessel, in accordance with development goals, and found to be entirely compatible with naval operations. The ATOL system‘s semi-autonomous and completely autonomous modes were successfully tested in various sea conditions.
Before those features are integrated into the fully autonomous VSR700, the OPV may carry one test pilot to enable safer and more rapid first testing. Initially, the OPV performed manned take-offs and landings before progressing to completely autonomous movements.
What makes Dassaults Rafale fighter jet so special?
The VSR700 is a 500-1,000 kg maximum take-off weight UAS designed to work with other shipborne naval weapons. It has the finest payload capabilities, endurance, and operational cost balance. It can carry numerous full-size naval sensors for lengthy periods of time and can operate alongside a helicopter from current ships with a small logistical footprint.
Airbus concludes ATTOL with fully autonomous flight tests
The VSR700’s initial prototype flew for the first time in 2020 and enlarged its flying envelope in 2021. The DGA ordered a second prototype of the VSR700 in April 2021, focusing on trials addressing SDAM criteria and allowing for broader, faster progress toward that aim.

Can Airline Seat Cushions Be Used As Life Jackets?
In the event of an aircraft ditching into water, there’s a common question: Can aircraft seats serve as an alternative to life jackets for flotation? The answer lies in understanding their respective functions.
While seat cushions can provide some buoyancy in water, they are not intended nor certified to function as life jackets. Their primary purpose is to offer cushioning for passengers during flight. On the other hand, life jackets are meticulously engineered to keep individuals afloat in water, equipped with buoyancy materials, secure straps, and reflective elements for visibility. They offer numerous advantages over mere cushions.
While a seat cushion might offer temporary assistance in staying afloat, it’s not a dependable substitute for a proper life jacket during an emergency. It’s crucial to utilize approved safety equipment when near bodies of water. A life jacket, designed to keep a person buoyant for extended periods, offers the rigidity needed for prolonged flotation and allows for easy movement of the arms to navigate effectively.
What fabric is used in aircraft seats?
Seats are meticulously designed to fulfill multiple purposes, ensuring passenger comfort, safety, and protection from unforeseen circumstances like fires and accidents. A typical design incorporates an aluminum frame with blocks of polyurethane foam affixed to it. Additionally, a layer of fire-resistant fabric, such as Kevlar or Nomex, is often applied over this framework, topped with a layer of cloth or leather.
Leather seats, while luxurious, are more expensive compared to traditional cloth seats. The majority of fabrics used in seat upholstery contain at least 90% wool fiber, with the remainder typically consisting of polyamide (nylon). Wool stands out as the primary fiber chosen for commercial airline seating fabric due to its desirable properties and suitability for such applications.
What is the lightest economy seat?
In recent times, airlines have been downsizing seat dimensions to accommodate more passengers, resulting in reduced cushion length and leg space. This contrasts with earlier times when airlines offered more generously cushioned seats and ample amenities.
According to Recaro Seats Company, their SL3710 model represents the lightest economy class seat available, weighing in at a mere 8 kg (17.6 lb.), setting a new standard in aircraft seating.
For individuals weighing more than 350 pounds, fitting into a standard economy-class seat can be a challenge due to the narrower dimensions. Economy seats, also referred to as “coach,” “standard,” or “main cabin” seats, typically range from about 40 to 48 centimeters in width, further emphasizing the need for more accommodating seating options.
