We are planning a trip next month to Easter Island (South Pacific) in a GV. Our routing takes us overhead Galapagos and then through an area designated on the SA 8 High chart as "No FIR". This area covers about 700 miles of our route between Guayaquil FIR and Pascua FIR. They do give New York Radio HF freq's. Has anyone flown in this area? What proceedures are used when operation through this airspace?
