Comments on: Why do hundreds of airliners all cross the Atlantic Ocean from the US at the same time each morning? http://www.thewoodcross.org/wordpress/cross/why-do-hundreds-of-airliners-all-cross-the-atlantic-ocean-from-the-us-at-the-same-time-each-morning Catholic & Orthodox discussion Mon, 21 Jun 2010 14:39:59 +0000 http://wordpress.org/?v=2.9.2 hourly 1 By: zanymadpilot http://www.thewoodcross.org/wordpress/cross/why-do-hundreds-of-airliners-all-cross-the-atlantic-ocean-from-the-us-at-the-same-time-each-morning/comment-page-1#comment-5092 zanymadpilot Mon, 28 Sep 2009 06:08:59 +0000 http://www.thewoodcross.org/wordpress/cross/why-do-hundreds-of-airliners-all-cross-the-atlantic-ocean-from-the-us-at-the-same-time-each-morning#comment-5092 Av8trxx is quite right. The other issue is also wind. ATC only open the NATS (North Atlantic Track System) at limited hours. That doesn't stop private business jet flying, and believe me they do! One of the primary objectives in any flight in any airspace is to avoid the areas of strongest headwind while seeking the areas of strongest tailwind. Over the North Atlantic the predominant westerly winds are found at mid-latitudes, 50 to 55 degrees North. As a consequence of this the westbound flow will normally North or South of this and the eastbound will attempt to fly through it. Naturally this doesn't happen on a daily basis but in general this is the hypnosis which lead to the creation of an organised track system. The Eastbound system is open between 1130 - 1800UTC and eastbound 0100 - 0800UTC. The aircraft are seperated laterally and by speed.<br><b>References : </b><br>I'm an Airline Transport Pilot, flown the NATS system Av8trxx is quite right. The other issue is also wind.

This is because you lose a day when you travel east.<br><b>References : </b><br> All lanes are going to different places and also that when you leave here in the morning you’ll reach the other side at night or late afternoon.

If everyone wanted to arrive in the evening, the morning flights would not fill, and the airlines would not have them.<br><b>References : </b><br> simply put, because this is the time passengers want to fly.

No one wants to get to their destination at night when everything is closed and they must get a hotel (especiially if they managed to sleep on the flight across). Getting there in the AM or mid day if far more preferrable, especially to business travellers.<br><b>References : </b><br> So you can arrive at a productive time of day.
