Hello,Perfect add on. I cant fly anymore without it.I have made many many many flights with iFly/Fs2crew for FS9.However the last week I had 2 CTD's.1) The first occured when I called the FO to set an altitude on the MCP while on the approach. Have in mind that, I was in circling procedure in the downwind (didnt select circling on the fs2crew menu-I never do :) ). I started the approach in the ILS and then exited the ILS approach at 1500 ft in order to do the circling. Also, during the ILS approach hitting HDG on the MCP didnt worked to exit the localiser (i dont know what the heck happens in the real thing), and I had to cycle ON and OFF the FD. I exited the ILS and while hand flying on downwind I told the FO to set a specific altitude on the MCP. He didnt reply after my command, and immediatelly after a short freeze BOOM, CTD.2) The second CTD occured yesterday, on the preflight. I run through the preflight checklists without having complete the departure briefing. However I do it regularly without problems, the FO just replies "Are you sure about that?" and thats all. Yesterday, he didnt reply and after a short freeze, and BOOM, CTD again. :)I didnt kept the CVR the first time because of the software been so stable, I thought that it was a random effect and maybe other factors were contributing to the CTD.However the second time I was sure that this was an FS2crew side-effect. I didnt kept again the CVR because I was online with friends and I had to setup the flight deck again quickly to get the bird in the air.I will keep the CVR's from now on if that happens again, and let you know.

Hi,Please search the Avsim CTD forum for ideas.We have a very large user base, and CTDs are hardly ever reported.However, I follow the forums closely and the main culprit for CTDs these days seems to be coming off certain 3rd party sceneries and AI traffic.The amount of 'overhead' FS2Crew adds to the sim is not very high. It's not a 'graphic orientated' program and there are no huge textures that eat up gobbs of memory and resources - that's the real killer stuff.So I'd suggest checking your scenery and maybe moving your sliders a little to the left.Cheers,
