measure the landing load of "light" and "heavy", the aviation industry has introduced the concept of vertical acceleration, the measurement of special equipment installed on the aircraft, the value of quality to determine the landing by vertical acceleration measurement. Airbus Company and Boeing ...
present, the Boeing 737 and Airbus A320 series aircraft, most companies will be the vertical acceleration is greater than or equal to 2.00g for landing, landing. Due to heavy landing The reasons causing the heavy landing varied, generally, ...
this growth won’t happen nearly fast enough, and as we’ll see in chapter 4, without innovation it won’t be enough to get us all the way to zero. We have to force an unnaturally speedy transition. That introduces a level of complexity—in public policy and technology—that we’ve...
KENNEDY SPACE CENTER, Fla. –Ahead of Boeing’s Starliner spacecraft's first crewed launch, two veteran NASA astronauts reflected on the differences between their previous rides to space, including the new ability to avoid areas known as "black zones" where a spacecraft crew would likely not s...
Pressurized cabins enable pilots, crew and passengers to avoid these pitfalls of flying at high altitude. While the air outside the cabin thins out the higher a plane climbs, compressed air inside the cabin maintains more surface-level air pressure and oxygen-rich air. In the event of accident...
Nobody ever expects to be the victim, but criminals are constantly fine-tuning their techniques and operating from well-worn playbooks. Here are tips on how to avoid some of the most devastating schemes and what to do if you or someone you care about becomes ensnared. ...

Von Schantz also said flying in newer models with a lighter frame, like the Airbus A350 or Boeing 787 Dreamliner, would help. That’s because those planes can maintain a more comfortable cabin atmosphere, which should help travelers feel less worn out by the end of their flights. ...
“We’ve looked quite significantly at electrothermal systems. They are used on the Boeing 787, but it was found that you need quite a large amount of electrical energy to provide full protection over the entire flight envelope,” says Baty. “We have done ...
While regular ballistic missiles can reach hypersonic speed, hypersonic missiles can travel at lower altitudes and are highly maneuverable, allowing them to avoid anti-ballistic missiles (ABM). The two main hypersonic weapons are hypersonic glide vehicles (HGV) and hypersonic cruise missiles (HCM). ...
