Due to a recent outage, Weather/NOTAM data may not be accurate or complete.
Though data has been restored, flight conditions should be verified prior to departure.
When flying between a Leidos Flight Service (LFS) and non-LFS service area, the start and/or end time of
the SE-SAR service depends upon communications between LFS and the country or agency responsible for the other
service area. As a result, SE-SAR start or end time can vary.
For a flight departing from within
the LFS service area, and arriving at a non-LFS service area:
For a domestic flight plan, SE-SAR service will typically end shortly after departure.
For an ICAO flight plan, if you contact an LFS specialist and provide a position report indicating you are
leaving the LFS service area, SE-SAR service will end at that time.
For a flight departing from a non-LFS service area, and arriving in the LFS service area:
For a domestic flight plan, SE-SAR service will typically begin shortly after departure.
For an ICAO flight plan, if you contact an LFS specialist and give a position report indicating you are
entering the LFS service area, SE-SAR service will begin at that time.

Radar and Satellite Products Added to Interactive Weather Map
Additional CONUS Radar and Satellite products have been added to the Interactive Weather Map.Composite
and Forecast Base Reflectivity Radar, and Water Vapor and Forecast Water Vapor Satellite are now selectable
from the layer control. Use the same control on the lower left to animate the selected product's display.
UAS Operating Area (UOA) Changes
Currently our web site and web services have two types of UOA, those that are associated with NOTAMs and
those that a UAS operator chooses to create. NOTAMs are required only of certain commercial flights, and
only those that are required to submit a NOTAM can submit a NOTAM. We also currently allow any user to
create a UAS Operating Area (UOA) to self-announce, but it is not required. The issue with this current
paradigm is that we are unable to create a full and accurate picture of all UAS operations.
We show all NOTAM UOAs but only the non-NOTAM UOAs that a user volunteers to submit, which can be misleading.
Due to these concerns, we are augmenting our UOA service to only focus on the UAS NOTAMs.
We will still support UOA management and viewing, but only for UOAs associated with NOTAMs.
This change will include the following modifications to our website and services:
The UAS management web page will be updated to reflect that UOA creation
requires a valid COA and NOTAM submission is required.
The UOA graphics, briefing, and alerting will be updated to only include NOTAM UOAs.
The briefing and alerting for UOAs will be updated to only include NOTAM UOAs.
UOAs that we publish to web service vendors will only include NOTAM UOAs.
This warning dialog is now displayed only when briefing flight plans where the route of flight penetrates
Added the ability to define checklists of the various weather product layers you wish to view on the
interface weather map. As you step through your checklist, only those phenomena that intersect your

To better support IFR ICAO flight plans requesting Data Link communications (DataComm), when a J
code (J1-J7) is entered in the aircraft equipment field and a user performs a flight plan action
(File/Amend/Activate), a popup dialog is presented. The dialog informs users of Other Information
field data that is needed for DataComm services and, based on their dialog selection, either
populates the field with the required REG/ and DAT/ subfields, or allows users to opt out and
proceed with the intended flight plan action.
Improved EasyActivate™ and EasyClose™
The Pilot Web EasyActivateTM capability has been enhanced to allow the user to activate the flight
'now', activate with a new time that is within 30 minutes of the current time, or to cancel the flight.
The Pilot Web EasyCloseTM capability now requires the user to enter a location of three or more
alphanumeric characters upon closing the flight plan similar to Pilot Web. Note: All SMS input
from users will be followed by an SMS system response. A lack of response from the system may
indicate an intermittent service outage. NOTE: Standard carrier text message rates may apply.
SMS messaging for ACAS, Close Reminder, and SE-SAR capabilities
The Adverse Condition Alerting Service (ACAS) and Close Reminder and Surveillance Enhanced Search and
Rescue (SE-SAR) text messages will now be sent using the same SMS provider that is used for the
EasyActivate/EasyClose messages. Users will no longer be required to specify their cellular service
provider during registration, making these services available to all devices with SMS capabilities
Garmin inReach devices
Since Garmin acquired DeLorme and rebranded the DeLorme inReach devices as Garmin inReach, references to
DeLorme on the website will now be renamed Garmin inReach (DeLorme). Usage and registration of these
devices has not changed.
Removal of Volcanic Ash Advisory (VAA) tab from
Pilot Web Briefings
To reduce the amount of duplicate content in the briefings,
the VAA tab and related section in the All tab have been removed
from the Pilot Web briefings. The VAA information continues to be
included in the Flow Control tab in the Pilot Web briefings and the
Flow Control section of Web Service briefing responses.
