I am happy again with the AI. I have made flights to Kabul from Basra and Frankfurt am Main from Bagram. The mountains did not deter me. I could explore full payload and full fuel load although --- I then decided to challenge the Sierra Madre. First from a long flight over the jungle and then over the high plateau from SBGL, Rio Janeiro to Santiago as Arturo Merino Benitez International, SCEL. That done I did Estancia Nueva from Lubecka Airport, SAJO up the coast instead of down to SCEL. Just because you can jump to FINAL one day and not get a "You do not have enough fuel to jump to FINAL" does not mean you can always gross up to what can be flown off the departure runway and miss all the obstacles. It's a play of wind, mountain wave and ATC clearances with no XPDR operating for me.
