🚁 Eve Air Mobility EVE-10 is one step closer to certification! 🚁 On November 1st, the Brazilian National Civil Aviation Agency ( ANAC - Agência Nacional de Aviação Civil ANAC) published Ordinance No. 15,760. What does it mean? This document outlines airworthiness criteria, setting the regulatory foundation for EVE Soluções de Mobilidade Aérea Urbana’s groundbreaking EVE-10 eVTOL aircraft. Here’s why this matters: 1️⃣ 𝐅𝐥𝐢𝐠𝐡𝐭 𝐒𝐚𝐟𝐞𝐭𝐲 𝐚𝐭 𝐭𝐡𝐞 𝐂𝐨𝐫𝐞   The criteria define structural, control, propulsion, and battery requirements. Every detail ensures that safety isn’t just a priority—it’s guaranteed. 2️⃣ 𝐓𝐫𝐚𝐢𝐥𝐛𝐥𝐚𝐳𝐢𝐧𝐠 𝐚 𝐍𝐞𝐰 𝐏𝐚𝐭𝐡   Since eVTOL tech is new to aviation, no ready-made regulations apply. ANAC took a hybrid approach, using existing rules and adding criteria to ensure safety and reliability. 3️⃣ 𝐆𝐥𝐨𝐛𝐚𝐥 𝐀𝐥𝐢𝐠𝐧𝐦𝐞𝐧𝐭 𝐟𝐨𝐫 𝐅𝐚𝐢𝐫 𝐂𝐨𝐦𝐩𝐞𝐭𝐢𝐭𝐢𝐨𝐧   ANAC opened a public consultation, gathering 297 contributions to shape the criteria. This collaborative approach strengthens the certification process and positions Brazil as a competitive force in global aviation. 𝐖𝐡𝐚𝐭’𝐬 𝐍𝐞𝐱𝐭? Now that the certification criteria are in place, EVE-10 moves into the next phase: compliance verification. Step by step, we’re getting closer to seeing this revolutionary aircraft in the skies! #UrbanAirMobility #eVTOL #EVE10 #AviationInnovation #SafetyFirst #ANAC

𝘽𝙞𝙧𝙙𝙨 𝙘𝙖𝙣 𝙛𝙡𝙮 𝙖𝙣𝙙 𝙬𝙞𝙣𝙜𝙨 𝙘𝙖𝙣 𝙛𝙤𝙡𝙙! It's all about 777X foldable wing tips. To watch things in action, it'd be a feast for the eyes of the marvelous engineering design. 𝗪𝗵𝗮𝘁 𝗶𝘀 𝗮 𝗳𝗼𝗹𝗱𝗮𝗯𝗹𝗲 𝘄𝗶𝗻𝗴 𝘁𝗶𝗽? You read it right. It is the only wide-body aircraft in the world that has mastered the feature of foldable wing tips. The wing tips extend and lock while on the runway during takeoff and in the air, and they remain folded after landing. 𝗪𝗵𝘆 𝗶𝘀 𝗶𝘁 𝗻𝗲𝗲𝗱𝗲𝗱? This is to keep the wingspan of the aircraft within the operational limits of code E standards, which are limited to 213 feet. The Boeing 777X on the ground operates at approx. 212 feet. 𝗪𝗵𝘆 𝘁𝗵𝗲 𝗹𝗼𝗻𝗴𝗲𝗿 𝘄𝗶𝗻𝗴 𝘁𝗶𝗽? The longer wing tip increases the wing span, which contributes to achieving more aerodynamic lift by reducing the wing tip vortices that cause lift-induced drag, which makes it more economical and fuel-efficient than its predecessor. 𝗪𝗵𝗮𝘁 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝗰𝗲 𝗱𝗼𝗲𝘀 𝗶𝘁 𝗺𝗮𝗸𝗲 𝗼𝗻 𝗹𝗮𝗻𝗱 𝗮𝗻𝗱 𝗮𝗶𝗿𝗯𝗼𝗿𝗻𝗲? It makes a pretty huge difference as the wingspan extended measures up to 235 feet and upon folding measures up to 212 feet 7 inches.

🔧✈️ What is a flap? Flaps are devices on an aircraft's wings that increase lift during takeoff and landing. Without them, planes would need much longer runways to operate! 💬 Have you noticed how the wings move during landing? Next time you fly, watch the flaps in action!

WHY DON’T PLANES FLY OVER TIBET? If you look at the Flight Radar app, you will see that although there are many planes flying all over the world, there are no planes in the Tibet region of China. So why don’t planes fly over Tibet? When they fly over Tibet, why do they go around it if they can fly over for a shorter period? In fact, the answer to this question is hidden in the “roof of the world” analogy used for Tibet. Tibet is a geography with an average altitude of 5,000 meters above sea level and is home to Mount Everest, the highest point in the world. So what does this have to do with planes? The cabins of modern passenger aircraft are pressurized. When this pressure system malfunctions, the oxygen masks are activated first to allow passengers to breathe. However, the capacity of the oxygen system is enough for 15 to 20 minutes on average. Therefore, when a malfunction occurs in the cabin pressure system, pilots have to pull the plane to an altitude of 3,000 meters. In most of the Tibetan region, the altitude is well above 3,000 meters. There is no environment in Tibet where planes can safely descend in an emergency. In addition, when one of the engines fails on a twin-engine aircraft, the aircraft must descend to a certain altitude in order to fly safely. Unfortunately, this is not possible due to the geographical structure of Tibet. For these reasons, no planes fly over Tibet. These factors, combined, cause airlines to avoid routes that fly over Tibet, preferring to bypass the region. Regarding sources, you can check this type of information on aviation websites and publications, such as Flight Global, Aviation Stack Exchange, and even flight safety documents from organizations such as the FAA (US Federal Aviation Administration) and ICAO (International Civil Aviation Organization), which discuss route planning factors and operational safety in regions of extreme altitudes.

A stunning recreation of the air flow behavior of an airplane's wing brake system ✈️. This behavior demonstrates the importance of the drag force in reducing the airplane's speed. In the same way, the airflow changes its behavior from laminar to turbulent. 🌪️ #aerodynamics #air_velocity #aeronotics_engineering

📢 ⚠️ Check this out! Brazil's National Civil Aviation Agency #ANAC grants Speedbird Aero yet another unprecedented authorization... With the new permanent exemption, Speedbird Aero has included its first two drone models certified for cargo delivery, expanding its logistics operations. This is the #first #permanent #exemption granted to a company in Brazil, and the authorization is conditional on a pre-established route, located over the Godofredo Diniz bridge, in Aracaju (SE). To ensure that deliveries occur safely, the company has demonstrated compliance with several safety requirements, ensuring that there are no impacts on air safety or third parties. One example of a measure adopted is the requirement for an approved parachute, which automatically deploys in the event of a drone failure — a crucial point for granting the exemption. ANAC considers this permanent exemption process to be a #milestone of great relevance for society, as it represents progress in the regulation of drones, a technology that has been gaining more and more applications. The Agency seeks to balance technological innovation with maintaining the highest safety standards, which is essential for the successful development of civil aviation. By granting this exemption, ANAC not only optimizes the administrative process, reducing the need to evaluate similar requests, but also provides an efficiency gain in the use of public resources. This makes the process more efficient and predictable, benefiting both companies in the sector and society as a whole.

Desmistificando o Motor a Jato na Chuva! Você já se perguntou como os motores a jato funcionam mesmo quando está chovendo? É incrível como a engenharia da aviação é projetada para lidar com diferentes condições climáticas, incluindo a chuva! **Aqui estão alguns pontos interessantes sobre isso:** 1. **Resistência à Água**: Os motores a jato são projetados para serem resistentes à água. As entradas de ar são cuidadosamente projetadas para evitar que grandes quantidades de água entrem no motor. Isso significa que, mesmo em uma tempestade, o motor pode funcionar normalmente. 2. **Sistema de Drenagem**: Dentro do motor, há sistemas de drenagem que ajudam a remover qualquer água que possa entrar. Isso garante que o motor não sofra danos e continue operando de forma eficiente. 3. **Funcionamento em Alta Velocidade**: Durante o voo, os motores a jato funcionam em alta velocidade e são capazes de expelir qualquer água que possa ter entrado. A força do ar sendo sugado pelo motor ajuda a manter a água longe das partes críticas. 4. **Testes Rigorosos**: Antes de serem certificados para voar, os motores a jato passam por testes rigorosos em diferentes condicões climáticas, incluindo chuvas intensas. Isso garante que eles possam operar com segurança em diversas situações. 5. **Segurança em Primeiro Lugar**: Pilotos e engenheiros sempre monitoram as condições meteorológicas antes e durante o voo. Se as condições forem perigosas, eles podem optar por adiar ou redirecionar o voo para garantir a segurança de todos. Assim, da próxima vez que você ouvir um avião voando sob a chuva, saiba que seus motores estão prontos para lidar com isso! A tecnologia da aviação continua a impressionar com sua capacidade de enfrentar os desafios do clima. #Aviação #Motores AJato #EngenhariaAérea #Desafios DoClima #Aeronáutica #Aeronave #Aviação Vídeo: How A Jet Engine Works In Rain por Fact2Mystery | Canal: Fact2Mystery | Link do vídeo
