PCG P−5

departure end of takeoff runway (DER) elevation, is

within 10NM from the DER, and that penetrates that

airport/heliport’s diverse departure obstacle clear-

ance surface (OCS).

c.

An obstacle beyond 10NM from an airport/heli-

port that requires an obstacle departure procedure

(ODP) to ensure obstacle avoidance.

(See OBSTACLE.)
(See OBSTRUCTION.)

PROPOSED BOUNDARY CROSSING TIME−

Each center has a PBCT parameter for each internal

airport. Proposed internal flight plans are transmitted

to the adjacent center if the flight time along the

proposed route from the departure airport to the

center boundary is less than or equal to the value of

PBCT or if airport adaptation specifies transmission

regardless of PBCT.
PROPOSED DEPARTURE TIME− The time that the

aircraft expects to become airborne.
PROTECTED AIRSPACE− The airspace on either

side of an oceanic route/track that is equal to one-half

the lateral separation minimum except where

reduction of protected airspace has been authorized.
PROTECTED SEGMENT- The protected segment is

a segment on the amended TFM route that is to be

inhibited from automatic adapted route alteration by

ERAM.

PUBLISHED INSTRUMENT APPROACH

PROCEDURE VISUAL SEGMENT− A segment on

an IAP chart annotated as “Fly Visual to Airport” or

“Fly Visual.” A dashed arrow will indicate the visual

flight path on the profile and plan view with an

associated note on the approximate heading and

distance. The visual segment should be flown as a

dead reckoning course while maintaining visual

conditions.
PUBLISHED ROUTE− A route for which an IFR

altitude has been established and published; e.g.,

Federal Airways, Jet Routes, Area Navigation

Routes, Specified Direct Routes.
