Well, i was flying in a nice 737-900er delta textures from KDTW-KTPA. I was cruising at FL35 with a speed set for 265 KIAS. But, when I was checking my cruising speed, I was at a GS of 265 knots!!! I have not tampered with any CFG file regarding speed. I don't know how to make the KIAS speed show instead of GS!! BTW I had the the altimeter set for the standard 29.92. Any help please!!!!
