Hello, I still got a problem with gear down - flaps 15 - landing checlist to flaps!! After GS alive I speak the line: gear down - flaps 15 - landing checlist to flaps I see the tekst in the green bar correct! But the FO does not respond! I have to say this 5 or 6 times before i get a response from the FO !! This is very annoying and screws up my landing!! Is there another way to trigger the FO to respond to this gear down - flaps 15 - landing checklist to flaps?? It is strange because all the other checklist's work perfect!! What am i doing wrong and what can i try more?? Kind regards Robert
