Well,sometimes FSA touchdown VS is totally accurate,and sometimes showing -96 to rate of -161 lol
From EGKK to EDDF

Yeah. Why does it occur? I wanna see it accurate so I can improve my landings more As I am mostly not looking to VS indicator during landing

My network is high enough I think. /facepalm

Hi Gokalp

I don't know the answer to this I'm afraid. FS9 seems to throw up the odd one every now and again but I suffer a lot heavier landings consistently in FSX I presumed it was just 'me' and VC's but whatever I do, I can't get as good a landing V/S in FSX as I get in FS9

Not really. I mean that sometimes I did landings too rough,and checked touchdown,it was -60 or sth like that!!!

Maybe depends on the NET.
