Oceanic flying in Pilot Talk Posted 18 hours ago 1 hour ago, Jordan Breadon said: Can you message the controller for oceanic clearance the same you would for position reports or should it be done through the radio? It depends on the station. Some will accept clearance requests via text messages, some may support Hoppie ACARS, Gander/Shanwick has a website that you can (sometimes) use, some require calling in via the radio. The Oceanic FIRs all have documents explaining what is expected from you AFAIK. For example, for the North Atlantic, [Gander Oceanic](https://ganderoceanic.ca/) is a great starting point. 1 hour ago, Jordan Breadon said: If your departure airport is within the 40 minutes of oceanic entry can you get oceanic clearance off any position at the airport ground, tower etc or should you wait until after departure to get it. In principle, you can get your oceanic clearance whenever it suits you, provided you do it well in advance (at least 30 minutes before oceanic entry). However, you don't want to have to make your request during the "sterile cockpit" phase of the flight (takeoff roll to 10,000 feet), so generally if your oceanic entry is less than 40 minutes from your departure, you would typically get the oceanic clearance on the ground, and if it's later, you'd get airborne and climb out to 10,000 first, and then make your request when you have a low-workload moment. 1 hour ago, Jordan Breadon said: Is oceanic clearance require for flying over the south atlantic ocean? Yes. All oceanic airspace requires oceanic clearances, with a few exceptions for domestic flights in countries that lie within oceanic airspace, e.g. Iceland or Greenland. However, oceanic control facilities over the South Atlantic aren't staffed often on VATSIM, and when there are no controllers, you obviously can't get an oceanic clearance, so in practice, you will most likely fly there without an oceanic clearance - just like you don't get a regular IFR clearance when you depart on Unicom in domestic airspace.
