Hi Eff Oh,
Just to clarify this, I was talking about the actual EADI display not the numbers on the selector panel. On all mine when you get to 0' the green display dissapears, on others it shows all the way down to -20'.
It caused an interesting discussion as we wondered if you have the -20' displayed on the EADI, what do you use it for? After all a DH is a decision height, and if it's in negative values then surely you have already hit the ground!
Would appreciate some views and polls on this as I am about to lose a beer or three!
