Avi8or created the topic: 100ft correction
Hey, I need help regarding the 100ft correction which applies when there is an accurate QNH source available and the box in the DAPs is shaded. Which value(s) do you minus the 100ft from? I understand that we minus 100ft from the alternate cloud base, but do you minus 100ft from the the S-I and Circling cloud base as well? Also do you minus the 100ft from the MDA (or DA) or just the cloud base?
