I have tried to create a flightplan from Teteboro (KTEB) to Lisbon (LPPT). This route is a route the Citation Longitude is capable of according to miles and flighttime endurance. Many private jet charters including Netjets for instance are offering the Northern Atlantic crossing and even Textron Aviation is showing on their home page that this flight is within the operating range of the aircraft. I am not sure if it is allowed to post a link here but you can surely check that easily by yourself. If I now generate this flight it is telling me in the PDF that the range of the aircraft is exceeded and gives me an ETOPS warning. Could you guys please review the weights and performance data for this aircraft?
