Blazing a trail with solar power
In a hangar outside Zurich, engineers are paring away at the obstacles to a very 21st century challenge: flying a plane around the world powered by nothing but the rays of the sun. If the Solar Impulse project goes to plan, in 2011 a gangly aircraft with the wingspan of an Airbus A380 and the weight of a compact car will attempt to circle the globe in about a month at an average speed of 43 m.p.h. (70 km/h), landing only five times along the way.
The challenge, says Piccard, is to keep going until the next sunrise before the batteries are empty: “We have very little margin of error from night into day. Each dawn will be a moment of incredible suspense.” For the 2011 flight, he and Boschberg will do alternating stints of five days and five nights between landings. A day on the ground spent charging in the sunlight should be enough to get the plane back into the air the next morning for another stage in its globe-girdling journey.
It’s a delicate enterprise, complicated by meteorological challenges and the ungainliness of a plane this big and light. Even Piccard doesn’t envision solar planes replacing today’s airliners anytime soon, but that’s not the point. To reduce emissions, he believes, aviation will eventually need to wean itself from fossil fuels. “To make reasonable use of any alternative,” he says, “we have to become lighter and more aerodynamic to reduce consumption.” Solar Impulse promises to generate an array of futuristic insights — and some old-fashioned thrills along the way.

A evolução do conhecimento levada a cabo pelo homem no século XX foi, sem dúvida, uma revolução de extensão mais significativa do que qualquer movimento que, deliberadamente, tenha reivindicado esse título. Do marco inicial da psicanálise, ainda no limiar do século XIX, às atuais experiências com células-tronco, passando por grandes descobertas, como a penicilina ou a criação das redes virtuais, a Era dos Extremos modificou categoricamente a visão do homem sobre o próprio homem. Mas, se de um lado parecem ruir os ideais iluministas que depositavam no reino da razão as esperanças de evolução das relações da existência individual e coletiva, de outro as formas de organização concebidas em consonância com esses ideais, representadas pela moderna democracia republicana, parecem ainda não ter perdido sua atualidade. Senão pelas suas virtudes, ao menos pela ausência de outras alternativas que se tenham mostrado melhores. Porém, de que forma conciliar o funcionamento de tais instituições com as novas — e nem sempre coincidentes — visões que as mais diversas áreas do conhecimento produziram sobre o homem?

Skydive operations:
what the typical pilot should know
what the typical pilot should know
A bird strike by an aircraft can cause some damage to any aircraft, but what happens when that ‘bird’ weighs 170 or more pounds? The ‘birds I’m discussing in this article aren’t really birds at all, they are skydivers, or people jumping out of airplanes. The answer to the question is that the airplane will likely suffer damage sufficient enough to cause permanent loss of control of the aircraft, and thus, serious injury or death to all the aircraft’s occupants and the skydiver. In addition, a collision with a skydiver with an open parachute could be even worse, due to the intense drag created by the parachute entangled with the aircraft.
Now that we realize the dangers of mixing falling skydivers and flying aircraft one might wonder how to avoid such a conflict. During my initial flight training while studying sectional charts and the myriad of numbers, texts, and symbols, I remember seeing the icon that indicates parachute operations take place at an airport. That, however, was the extent of my knowledge of parachuting operations at airports (or drop zones as they are called in the sport.)
As a pilot for skydivers we constantly try to visually scan the intended jump area for aircraft in the area that may pose a threat, in addition we contact air traffic control (ATC) at least 5 minutes prior to the jump in order to get traffic advisories, though as a VFR operation, reports vary depending on how busy the controller may be. The jumpers exiting the aircraft also attempt to look for traffic prior to exiting. Additionally, the PIC of the jump aircraft typically reports the beginning of jump operations to ATC, and over the CTAF 1-2 minutes prior to the time when the first parachutist is to exit the aircraft. Radio calls made over CTAF usually include the airport where jump operations are taking place, the time until jumping will start, and the altitude the jumper(s) will exit. After the last parachutist exits the aircraft the jump pilot reports to ATC that jumping is completed.

Based on the text, it can be deduced that
in the text, “wonder” is the same as wander.

Based on the text, it can be deduced that
after the last parachutist leaves out the aircraft, the jump pilot reports to ATC that jumping is over.

Based on the text, it can be deduced that
jumpers try to search for traffic before exiting, and furthermore, the PIC of the jump aircraft regularly gets in touch with ATC to inform about the beginning of jump operations.
