Terrestrial based tracking using the time difference of arrival to calculate position. Should give high positional accuracy during most phases of flight, but position errors can sometimes occur. The ground speed is calculated and can sometimes be incorrect, especially during turns and at low altitudes. Vertical speed is also calculated, so errors can sometimes occur. Altitude data come from the transponder and should be correct. Read more
As soon as I think of travel, it’s not long before my mind drifts to white sand beaches, azure blue water, and palm trees in tropical locales. When most people think of paradise, chances are they’re thinking of tropical islands is far-flung corners of the world. Lounging with a good book, drinking from coconuts, soaking up the rays. Does it get any better than that? 

Easily reached from both Split and Dubrovnik, Lastovo is packed with 15th- and 16th-century architecture, including countless churches in different styles. The island is rich in history, and the main town is full of the various types of architecture, including beautiful Renaissance houses. Lastovo and its surrounding islands is Croatia’s newest Nature Park.
Sarah-Jane — Thanks for another helpful article (this one on planning an island-hopping trip). Chasingthedonkey.com is a great website and my first go-to place for information on Croatia. I have scheduled my third 3-month-long stay and still have so much to do and see in Croatia. Personally, my favorite times to visit are in the “shoulder” seasons …. September-November and March-May.
Located in the middle of the Indian Ocean, the Maldives is a chain of 1,000 islands (200 are inhabited, and only 5 have any substantial population). The country is actually just a series of coral atolls that are barely above sea level. During the 2004 Tsunami, many of these islands were completely washed away. The government has built flood barriers to help lessen the impact of any future tsunamis.
I’m traveling to Greece for the first time, and I’m so fortunate to be staying for about 9 weeks (peak season, unfortunately, I’m an educator and it’s summer!). I have ample time planned in Athens, and the Peloponnese (with rental car). Here’s where I need some help and suggestions. I have 5 weeks saved for the islands and I’m still trying to figure out how to spend them. I’m not sure if I’d like to cover just a few islands and soak them in a bit deeper with longer stays…or to travel at a quicker pace covering several islands in each main area (the Cyclades, Ionians, Crete-Rhodes Dodecanese, Eastern Islands) I’m an easy traveler and enjoy diversity. I crave spending time with locals and interacting with families – home stays at times, I enjoy the water and I’m an avid diver, I like hiking and exploring. Also, want to perhaps relax a bit – food/wine tasting welcomed). I’m excited about the trip and my ideas are racing all over. Do you have some ideas and suggestions to share? A rough sketch itinerary for Greece? Thanks so much! 

The Island of Hawaii (i.e., the Big Island) contains 10 of the world’s 14 climate zones — the only spot on the planet with so many condensed into one small region. Lush tropical terrain rules the green, wet, windward side of the island (see Akaka Falls and Waianuenue/Rainbow Falls), while more arid beauty is on display at Hapuna Beach Park. You can even enter an ice climate at the mystical summit of Mauna Kea volcano, as well as Lake Waiau, one of the highest lakes in the United States.
Domestic air transport grew in China at 15.5 percent annually from 2001 to 2006. The rate of air travel globally increased at 3.7 percent per year over the same time. In the EU greenhouse gas emissions from aviation increased by 87% between 1990 and 2006.[75] However it must be compared with the flights increase, only in UK, between 1990 and 2006 terminal passengers increased from 100 000 thousands to 250 000 thousands.,[76] according to AEA reports every year, 750 million passengers travel by European airlines, which also share 40% of merchandise value in and out of Europe.[77] Without even pressure from "green activists", targeting lower ticket prices, generally, airlines do what is possible to cut the fuel consumption (and gas emissions connected therewith). Further, according to some reports, it can be concluded that the last piston-powered aircraft were as fuel-efficient as the average jet in 2005.[78]
We are planning to come back at the start of September for 2 weeks to visit different islands for some beach and sun. To give you some background, we loved Santorini, Milos and the quieter / smaller places in Crete (Loutro, Falassarna, Samaria Gorge). We enjoy beach time, some hiking, site seeing, good wine / food and good / buzzy atmosphere at night for dinner / tavernas. 

Blaca Hermitage in the south of the island is a must-visit, as well as Vidova Gora Mountain, which is the highest peak on the island, offering you stunning views across the Adriatic and to neighboring islands on a clear day. Brač is also where you’ll find the famous Zlatni Rat Beach, one of the absolute best Croatia beaches (and even in all of Europe) and a wonderful place to spend a day. This all makes Brač one of the best islands near Split, a perfect day trip from Croatia’s second-largest city.
