DH in MDA field for non precision approaches in A320
Hello,

can someone please explain the reason why it is necessary to put the decision height in the MDA field when using a non precision approach (e.g. RNAV)? I think the chosen value is then called DA instead of DH.
I do understand the reason behind DH and MDA and why to use DH on Cat III and MDA on Cat I landings. However I do not clearly understand the reason for taking the DH for the MDA field for an RNAV approach.

Thank you!

Best regards Andi
