RNP

NavSpecs. These procedures generally start with an
initial track or heading leg near the departure end of
runway (DER). In addition, these procedures require
system performance currently met by GPS or
DME/DME/IRU PBN systems that satisfy the criteria
discussed in the latest AC 90

procedures will be charted in the PBN box (for
example, 1.00 or 0.30).

2.

In the U.S., a specific procedure’s PBN

requirements will be prominently displayed in
separate, standardized notes boxes. For procedures
with PBN elements, the “PBN box” will contain the
procedure’s NavSpec(s); and, if required: specific
sensors or infrastructure needed for the navigation
solution, any additional or advanced functional
requirements, the minimum RNP value, and any
amplifying remarks. Items listed in this PBN box are
REQUIRED for the procedure’s PBN elements.
