JanTenner Posted May 12, 2011 Share Posted May 12, 2011 Hey there, I have a problem with the Orbx Lancair and for I think it is not a software problem but a user mistake I put it here instead of the support forum. My problem is that sometimes after flying a while at 8000 feet (havent flew higher yet) the manifold pressure is going down. It starts slowly but then it is tending to zero fast. All pressures and temperatures are green. Only fuel flow drops. I have changed the mixture with height and got this problem with and without fuel pump. The manifold pressure went up after a short time but I dont know if it is because of time or because I got deeper. Can anyone tell me what I did wrong? I havent found anything in the handbook. P.S.: I did fly within parameters given for flight states Link to comment Share on other sites More sharing options...
CoolP Posted May 12, 2011 Share Posted May 12, 2011 Maybe you are experiencing the icing feature of FSX. Just guessing though since your description follows my experience with some planes. A slight descent will give you back your power and you may break through that icing layer when coming back with a proper engine and some speed to climb above it. Here's a chart which helps to determine the possibility for icing to occur. This was a helpful post from someone in the Katana forums. You can do some test flights with all weather cleared to verify this assumption of mine. Link to comment Share on other sites More sharing options...
JanTenner Posted May 12, 2011 Author Share Posted May 12, 2011 Ah, thanks. That could be it. I´ve flown in clouds when it started. Will have a look at before I fly next time. Thanks a lot Link to comment Share on other sites More sharing options...
Jared Charalambous Posted May 12, 2011 Share Posted May 12, 2011 You should also get power back by pulling the alt air lever located on the bottom RH corner of the panel. Note that it is designed to get enough power back to allow you to get out of trouble, not to push through the icing layer. Link to comment Share on other sites More sharing options...
Heiko Glatthorn Posted May 13, 2011 Share Posted May 13, 2011 The 'H' key is my panic button... It's the default key for deicing systems. So if the aircraft has deicing it usually helps (reading the aircraft manual is also useful...) Link to comment Share on other sites More sharing options...
pocketwatch50 Posted May 14, 2011 Share Posted May 14, 2011 Also watch your trim controls. The aircraft is very sensitive to it and requires a lot of attention. Link to comment Share on other sites More sharing options...
