New style TDZ markers in the UK
Apologies if this has been asked before but I just wondered why the aiming point markers on some UK runways have been changed recently?
I am talking about the zig-zag style markers unique to the UK, which have been replaced by European style solid blocks.
So far I have seen them at Belfast (Int) and on the newly positioned touchdown zone on runway 33 at Birmingham - although I am guessing they will also be appearing on the 15 end when the resurfacing gets there in April.
Any insight would be interesting!
