admin , Jet-Pack (IPACS) the planes mentioned in the title, flying at any altitude, fl400 or any other, when I skip time in cruise on long flights, even though it is set to FMC, and MCP the normal cruising altitude, when I return from the time skip it increases by 1000 feet , if I jump 5 times, it is 45000 feet, causing loss of lift, on the 737-900Er this problem does not happen, please give me an answer, a hug from Brazil
