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

Naxiots once made considerable fortunes exporting potatoes, cheese, marble and emery. Locals bequeathed undesirable seaside plots - useless for farming - to their laziest offspring. When tourists cottoned on to the island's scores of fabulous beaches, these wastrels found themselves sitting on gold mines. The west coast of Naxos is fringed with mile upon mile of powdery sands. Agios Prokopios and Agia Anna delight toddlers and teenagers alike with their shallow waters and beach bars. As you head south, the beaches get wilder: Plaka, where you can gallop across the dunes on horseback, Mikri Vigla for windsurfing and kitesurfing, and crystal-clear Kastraki.

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?
– Any advice on where to go after for around 5 nights? Back to Naxos (we didn’t really move from the town last year unlike in Paros where we rented a car and saw the whole island)? What about Folegandros? Tinos? Milos? We would like somewhere with a nice town to walk around, upmarket, more couple less family, nice bars and things to see during the day bit also nice beaches etc?
A complicating factor is that of origin-destination control ("O&D control"). Someone purchasing a ticket from Melbourne to Sydney (as an example) for A$200 is competing with someone else who wants to fly Melbourne to Los Angeles through Sydney on the same flight, and who is willing to pay A$1400. Should the airline prefer the $1400 passenger, or the $200 passenger plus a possible Sydney-Los Angeles passenger willing to pay $1300? Airlines have to make hundreds of thousands of similar pricing decisions daily.
A limestone spike rising dramatically from the emerald waters of Phang Nga Bay, James Bond Island (Koh Tapu — Nail Island in Thai) earned its moniker from appearing in two 007 movies: The Man with the Golden Gun (1974) and Tomorrow Never Dies (1997). Excursions depart from the popular resort areas of Phuket, Khao Lak and Krabi on photogenic longtail boats. On the tour, explore secret lagoons, craggy sea caves and a floating village.

With its pastel villages, rolling olive groves and grand manor houses, the rest of the island recalls Tuscany - but with far better beaches. The smart set stay on Corfu's north-east coast (nicknamed Kensington-on-Sea) where the Rothschilds like to unwind. It's wall-to-wall Sloanes and speedboats at Agni, a tiny fishing village with three rival tavernas (Toula's is the best). From here, you can rent a boat and putter to your own cove: perhaps Nissaki, Agios Stefanos or Kerasia. These idyllic bays still resemble the 'delectable landscape' that Lawrence Durrell fell for in the 1930s — now back in vogue thanks to the ITV series, The Durrells. Or venture inland to Ambelonas, an enchanting winery, restaurant and cooking school that specialises in Corfiot dishes, such as squid with chickpea and turmeric mousse and rose petal jelly. Steer clear of the south, especially Kavos. Unless you happen to like wet T-shirt contests.
Be cautious with Santorini and kids. Some hotels don’t do kids (check carefully) and not all hotels are suitable for kids along the caldera lip. Many steps, confined spaces and other guests who don’t actually want to hear kids … Here’s an idea – look for a child-friendly hotel (perhaps on the beach at Perissá) and base yourself where the kids will like it and then take them to the caldera scene. There are a couple of child-friendly hotels on the Caldera, but they get booked very early in the year.
Although Germany lacked colonies, it also began expanding its services globally. In 1931, the airship Graf Zeppelin began offering regular scheduled passenger service between Germany and South America, usually every two weeks, which continued until 1937.[17] In 1936, the airship Hindenburg entered passenger service and successfully crossed the Atlantic 36 times before crashing at Lakehurst, New Jersey, on May 6, 1937.[18] In 1938, a weekly air service from Berlin to Kabul, Afghanistan, started operating.[19]
Major airlines dominated their routes through aggressive pricing and additional capacity offerings, often swamping new start-ups. In the place of high barriers to entry imposed by regulation, the major airlines implemented an equally high barrier called loss leader pricing.[38] In this strategy an already established and dominant airline stomps out its competition by lowering airfares on specific routes, below the cost of operating on it, choking out any chance a start-up airline may have. The industry side effect is an overall drop in revenue and service quality.[39] Since deregulation in 1978 the average domestic ticket price has dropped by 40%.[40] So has airline employee pay. By incurring massive losses, the airlines of the USA now rely upon a scourge of cyclical Chapter 11 bankruptcy proceedings to continue doing business.[41] America West Airlines (which has since merged with US Airways) remained a significant survivor from this new entrant era, as dozens, even hundreds, have gone under.
