Too slow ?
Definitely something wrong there - if you search the forum you'll find another post accusing it of being too fast! You may also come across discussion of the airbrakes staying out or something along those lines? I think the originator of that was directed to the support tickets, may be worth dropping one in yourself with as much detail as possible.
223 knots at 13 000 ' full throttle, what's the problem ? I can't go above FL210 without stall...
I think that may be related to my issue which is detailed in the last post on this forum page..
Im fairly confident that the issue is related to fuel pressurisation as the fuel pressure MIs on the centre panel are white and this is the only time I experience this issue. For me the issue only occurs after I’ve made the cockpit cold and dark and I follow the checklist to start engines. I follow the list exactly so I’m not sure what’s happening..
