(b) Time
4 NUMERICS giving
the estimated off-block time at the aerodrome in (a) in FPL and DLA messages transmitted before departure and in RQP message, if known, or
the actual time of departure from the aerodrome in (a) in ALR, DEP and SPL messages, or
the actual or estimated time of departure from the first point shown in the Route Field (see Field Type 15) in FPL messages derived from flight plans filed in the air, as shown by the letters AFIL in (a).

(a) Boundary Point (see Note 1)
The BOUNDARY POINT expressed either by a designator consisting of 2 to 5 characters, in Geographical Coordinates, in Abbreviated Geographical Coordinates, or by bearing and distance from a designated point (e.g. a VOR).
Note 1.— This point may be an agreed point located close to, rather than on, the FIR boundary.
Note 2.— See 1.6 for data conventions.
