Update:
Pre-load both CPT side's ANF and C/O side's ANF before landing can get rid of the touchdown stutter.And keep C/O side's ANF on before touchdown.
Thanks sir.There is another detail that seems to be important. The stutter doesnt not appear when the main gear touchdown, but after the main gear touchdown and when the nose gear is about to touchdown. This should be the moment when ANF starts to display on ND.
Yep,before 1.0.4 I have never got stutter when touchdown with BTV using.And now,when I only use BRK MED(No BTV using),and the ANF wont display when on touchdown,it wont stutter as well.
1,If BTV is not used, ANF wont display automaticlly,there will be no such problem.
2,If BTV is used, even if ANF has been pre-loaded in the air, when it touchdown , once the ND display ANF automaticlly will still experience lag.
