3.11.4. Voice Dissemination. Maintain instructions outlining priorities and procedures to
follow for local dissemination of observations by voice relay (e.g., read back by the person
receiving the data). Disseminate all observations immediately to local ATC agencies (e.g.,
tower, Radar Approach Control, Ground Control Approach), then to other users as established
locally. Also maintain a record (written or recording) of all the following when voice is used
to disseminate locally during outages of the primary system:
3.11.4.1. Actual time of observation (UTC).

3.11.4.2. Time (in minutes past the hour) the observation was transmitted to the tower and
other local ATC agencies.

3.11.4.3. Single element LOCALs for Altimeter setting, PA or DA (where required).

3.11.4.4. Initials of the weather technician making the dissemination and the initials of the
receiver at the supported agency.

3.11.5. Supplementary Identification of Observations. At limited-duty manual WFs/Dets and
gunnery ranges, identify the last observation of the day (METAR or SPECI) by adding the
term "LAST" following the last element in the observation text (e.g., TCU SE LAST), and
include the remark on the AF Form 3803/JET Form 3813, as applicable.
3.11.6. Delayed Reports. Transmit the contraction NIL at the standard time when it is evident
that a weather report will not be completed in time for scheduled transmission. (T-0).
(Example: METAR KDYS NIL.)
3.11.7. Reports Filed But not Transmitted. When an augmented observation is not able to be
transmitted longline before the next METAR or SPECI is required, transmit only the latest
observation longline. Enter "FIBI" (contraction for Filed But Impractical to Transmit) in
parenthesis in column 13 (FIBI). Include FIBI in a METAR only if a later observation
containing all elements of a METAR is available for transmission.

3.11.8. When a SPECI is not transmitted longline, transmit subsequent SPECI only when the
change between the last transmitted report and the current report meets the criteria for a SPECI.
Otherwise, enter (FIBI) in remarks for the current report and only disseminate it locally.

3.12. Longline Dissemination by other WFs/Dets. Enter a record of longline dissemination by
another WF/Det in parentheses in column 13 of AF Form 3803/JET Form 3813. Identify the
WF/Det that transmitted the observation longline and the initials of the individual that received the
data (e.g., [BY KGRF/DR], [BY 25 OWS/MS]).
3.13. Reports of a Volcanic Eruption. Reports of a Volcanic Eruption are disseminated
regardless of the delay. Use any reasonable means to disseminate the report.
