Departure Procedures

constraints. Crossing altitudes and speed restrictions

on ODPs cannot be canceled or amended by ATC.

i. PBN Departure Procedures

1. All public PBN SIDs and graphic ODPs are

normally designed using RNAV 1, RNP 1, or A−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 90−100, U.S. Terminal and

En Route Area Navigation (RNAV) Operations.

RNAV 1 and RNP 1 procedures must maintain a total

system error of not more than 1 NM for 95 percent of

the total flight time. Minimum values for A−RNP

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.
