Thanks, just entered and solved the issue!On the last flight I did with programmed FMC I've not checked theese alerts. My PC is a I7 940 with few Mhz of overclock, 6Gb of ram, and GTX285. It runs very well compared to other payware aircrafts, with a good framerate. I've not experienced out of memory issues or something else. The frame rate is not too high (I've locked to 20 but it runs a bit slower sometimes at low altitude or with clouds. I use DX10 preview and bloom, 1280*1024 32bits

Oh wow ok.

Stab Trim, Flt Control, Master Caution, MCP Alt 11,500 & ALT HOLD, TCAS Off. . . You might want to run some checklists before you crash this thing! :(

It was to make the screenshot, i've also forgot to remove unneeded fuel. About flt cont, it was a fault of the y/d, I switched it ON, it remained ON but the Off light remained lighted with master caution. Tcas was not necessary for the test ;)

Ok, I checked my manuals and from a pilot, the NGs needs the GW and if FMC is inoperative there is a knob on the main panel.But!!!!Autoslat is completely indipendent system that uses this logic:

• Angle-of-attack more than a limit.
• Airplane in the air
• Computed airspeed less than 230 knots
• TE flaps not up
• Autoslat function valid

But I cannot see autoslat working if GW is not set.
