Hi First of all, I would like to congrat Mr Javier Rollon and all of his team to this wonderful aircraft ! A pure dream to fly with her ! However, I have found a little bug at 18 000 ft with the autopilot. Before Take-off I have selected the 180 with the ALT button . And choose the VS mode to climb up to my desired FL. When the RJ approaching the Level, I saw the "Altitude Capture" displayed on the PFD and the Vertical Speed decreased. But when passing FL180, the VS staid 0.5 sec on 0 and then increased to 2200 ft/m and higher as you can see on my pictures. I haven't found any topic about this bug. And Again MERCI for this bird !!!
