@taguilo thanks for the reply.
I made another flight with a flight level of 27000FT and everything worked correctly. but I have and still have doubts. I hope the Just Flight guys maybe look into this
I give you the reason that the flights I have made I always go empty and with fuel between 2,000 to 8,000 KGS. Tomorrow I will try cargo and passengers.
Well I have always flown all planes from FSX with keyboard and mouse. I never liked joysticks, pedals or Z-Axis. by many factors. one of them is because of the little space I have in my room where I have my PC. I hope ASOBO, MSFS, Just Flight will think of people like me who fly with keyboard and mouse. I also hope that this will improve one day because the truth is I'm addicted to this plane
