This is a question born our of my own lack of experience, and I am sure there is a good reason for why the FAA does what it does. But what is the point of having separate standards for whether to list required equipment in the plan view vs. the note view? AIM 5-4-5(b) states that when radar or other equipment is required on portions of the procedure outside of the final approach segment, including the missed approach, required equipment will be listed in the notes box. Whereas equipment necessary to enter the route from the en route environment is listed on the plan view. This seems to create some redundancy and confusion. For example, see: http://www.airnav.com/depart?http://188.8.131.52/d-tpp/1605/06878ILD20.PDF Here we are told two times that DME is necessary. Wouldn't just once suffice? Alternatively, see: http://www.airnav.com/depart?http://184.108.40.206/d-tpp/1605/05733L21.PDF Here, DME required appears only in the notes box, and could easily be missed. Not that I am saying it's ok to skip the notes box. But the notice of required equipment not as conspicuous there as it is in the plan view. Why not just always list required equipment in the plan view?
