Narrative:
The commercial chart for ILS runway 4R at ewr shows the decision ht to be 202 ft AGL. Is this correct or a misprint? Usually the decision ht displayed as ft above touchdown zone elevation is a round number like 200 ft, not 202 ft. I believe that it is defined by the type of approach, ie, CAT I.
