Not sure about your background. Quite knowledgeable you seem from other posts but now you've completely misunderstood. There is a difference beteende LNAV+VNAV autoflight modes and LNAV+VNAV minima. In the 737 at least you can use LNAV+VNAV autoflight modes to LNAV minima at any temperature, as long as initial, any step down and decision altitude is corrected
It is simple, the procedure states NA below for VNAV.
When you apply correction as you stated above, do you inform ATC of your corrections?
Will ATC maintain minimal sep between the aircraft that have the ability to correct? Do you expect ATC to manage corrected and non-corrected altitudes?
It matters not if you can correct, or if you cannot, it matters with ATC....
Again, the plate referenced is simple. NA below.
