As stated, DH is always 'above threshold', but the picture is clouded by several ops manuals which err in this respect (including my last). Commonly they quote "Decision Height - Minimum 100 ft
radio" (my bold) and then go on to offer 'Radio' DH's well below 100. 90'RA' in one case, 91'RA' in another. Obviously the manual should state "Decision Height - Minimum 100 ft ATE" and then all would be well. Previous management were sadly ill-equipped to understand the error in the text. Hopefully new team are better 'equipped'
