Beryllium: used as a lightweight component in military equipment and in the aerospace industry. it is used in high-speed aircraft, missiles, space vehicles and communication satellites.
An aircraft flying at a faster speed consumes more fuel per distance than the same aircraft flying at a slower speed.
FORBES: Is The Next Boom In Travel A Sonic Boom From Boeing?
For most inter-city journeys of more than two hours and less than five, rail has the competitive edge in safety, reliability and speed over both aircraft and cars.
This margin depends on the size and speed of an aircraft, and re-ordering the queue can minimise the delay before all the planes get into the air (mathematicians call this the departure problem).
The fuselage and other parts of the airplane resemble the Piaggio Avanti that has become so successful as a jet-speed, affordable business aircraft.
Of this most recent spate of accidents, where many aboard have been able to walk away from the wreckage, it is worth noting that they occurred mostly in the landing phase, at relatively low altitude and speed and with the aircraft in question carrying only limited amounts of fuel.
Aircraft equipped with ADS-B are able to automatically send highly precise data, such as aircraft positioning and speed, to air traffic controllers every second.
The Bureau of Investigation and Analysis said the data indicated that Flight 447 crashed because the aircraft's speed sensors gave invalid readings.
Eighteen seconds later, you have slowed that aircraft to hover speed and can sit down in the landing zone to quickly on- or off-load the maximum things on the aircraft.

Indeed, it is a slower speed that enables such an aircraft to be so quiet: it would drift in to land rather than powering in, all engines blazing, as today's jets do.
Although regarded as a successful weapon, the aircraft's slow speed makes it vulnerable.
He is but one of thousands of examples of successful business people leveraging the speed and utility of a business aircraft and creating positive, tangible business results every day.
In July 1992, OSD effectively rejected the requirements established by the commands responsible for Special Operations Forces (SOF) and Navy Combat Search and Rescue (CSAR) for an aircraft with the high speed and long range capabilities critical to their respective missions.
Should any of you want to join along with Piccard and Borschberg as they fly across the country, you can hit the Solar Impulse Across America website to see a livestream from the cockpit, along with real-time altitude, air speed and battery status of the aircraft.
Finally, AgustaWestland surprised the HeliExpo crowd by revealing that it has been secretly testing an electrically powered tiltrotor, mixing the versatility of a vertical takeoff and land helicopter with the speed and range of a fixed-wing aircraft.
FORBES: Helicopter Industry's Success Secret: Market Diversity
Meanwhile, Boeing's Sonic Cruiser (a futuristic aircraft designed to fly at almost the speed of sound) has not been well received by airlines.
Hersman noted the aircraft was highly modified to improve its speed.
The engines would have variable nozzles, which would be fully opened on take-off and landing, so that the exhaust would be slow and relatively quiet, and narrowed when the aircraft was cruising, providing the necessary speed.
By sizing this vehicle for internal carriage, the full tactical and operational benefits of the Osprey's speed -- approximately 270 knots in its conventional aircraft mode -- can be exploited, instead of having to externally sling-load the larger and heavier HMMWV at a much reduced range and speed.
CENTERFORSECURITYPOLICY: The misguided howl'er over the Growler
Sudden changes in wind speed or direction, known as wind shear, can lift or smash aircraft into the ground during landing.
Reflecting its continued focus on innovation and continuous improvements in customer service, NetJets plans to have all future fleet aircraft, including light cabin models, delivered from the factory with high speed Internet service.
ENGADGET: NetJets begins Aircell in-flight WiFi installations, won't stop anytime soon
Colonel JOE CURTIN (Spokesman, Pentagon): The division has almost 300 helicopters, cargo, attack and reconnaissance-type aircraft, so it is an extremely capable division that can provide the necessary speed and shock effect that you would need in a large-scale combat operation.
So the U.S. Navy began developing upgrades to Aegis that would enable it to defend against the most widely proliferated ballistic missiles, which were relatively short-range and slow in speed in other words, targets that a system originally developed for dealing with aircraft might be able to address through relatively modest upgrades.
Opponents reckon they have colluded in making up optimistic projections about the speed with which airlines will change to yet-to-be-built clean, quiet aircraft.
The aircraft's transponder, which identifies the plane and relays details such as altitude and speed to controllers, stopped transmitting.
That speed is crucial for Boeing, which fell behind Airbus Industrie as the world's largest commercial aircraft maker last year.
It reported that an aircraft manufacturer in Chengdu held emergency meetings after the collision with managers and workings vowing to speed up the development of Chinese fighter jets to "strengthen Chinese defense might".
As the Marines begin to operate these aircraft, moreover, it seems certain that the demand for planes with the inherent flexibility, speed, survivability and cost-effectiveness of the V-22 will only grow.
