11. Block 11. Enter only those remarks pertin-
ent to ATC or to the clarification of other flight plan
information, such as the appropriate radiotelephony
(call sign) associated with the FAA-assigned
three-letter company designator filed in Block 2, if
the radiotelephony is new or has changed within the
last 60 days. In cases where there is no three-letter
designator but only an assigned radiotelephony or an
assigned three-letter designator is used in a medical
emergency, the radiotelephony must be included in
the remarks field. Items of a personal nature are not
accepted.

1. The pilot is responsible for knowing when it is
appropriate to file the radiotelephony in remarks under the
60-day rule or when using FAA special radiotelephony

assignments.
2. "DVRSN" should be placed in Block 11 only if the
pilot/company is requesting priority handling to their
original destination from ATC as a result of a diversion as

defined in the Pilot/Controller Glossary.

3. Do not assume that remarks will be automatically
transmitted to every controller. Specific ATC or en route
requests should be made directly to the appropriate
controller.

computed from the departure point.

desired or required, but do not include routing to the
