When does Search and Rescue begin?
A VFR/DVFR flight plan is considered overdue when it fails to arrive 30 minutes after its estimated time of arrival (ETA), and Leidos Flight Service begins Search and Rescue at that time.
ATC conducts search and rescue on IFR flight plans.
How early can I file my flight plan?
You can file a flight plan up to 27 days prior to the planned departure date/time.
Why did a specialist tell me, "VFR not recommended"?
The decision-making process for a pilot is complex and while a specialist cannot make decisions for a pilot, they have standards in place that allow them to make recommendations.
Our specialists use the phrase "VFR Flight not recommended" (VNR Statement) when the requested briefing is for a proposed VFR flight and sky conditions or visibilities are present or forecast, surface or aloft, that make flight under visual flight rules doubtful. If you're confused about why you were issued a VNR Statement, be sure to ask the specialist the reasoning for the VNR Statement and an outlook for conditions to improve.
What online tools are available to activate or close my VFR flight plan?
You will first need to create a Flight Service website account. From the Dashboard, select EasyActivate EasyClose. A full description of the electronic flight plan activation and closure service is provided, and you can choose from several delivery options for activating and closing flight plans.

There is no requirement to call Leidos Flight Service to be compliant with FAR 91.103.
Does the FAA require a self-briefing to be recorded or digitally logged as proof that the briefing was conducted?
No. However, it is a good idea to have a record of your briefing in case you need to reference it later. Flight Service retains online briefings for 45 days.
I'm a flight instructor - how do I teach my students to self-brief from Day One?
As your student's flight instructor, you are their primary learning resource. It is recommended that pilots obtain a full preflight briefing prior to every flight. Furthermore, to promote pilot comfort with the subject and practical application of weather, we recommend that students generate an online weather briefing to familiarize themselves with their route and the potential hazards before placing a phone call to a Leidos Flight Service specialist with questions. To promote comfort and familiarity with weather, Leidos Flight Service is shifting towards a more of a "when needed" consultative briefing approach.

When you share your aircraft and favorite flight plans, other pilots can access your aircraft with the pre-stored aircraft information. If there are any favorite flight plans saved to that aircraft, they can populate your favorite flight plan. Note: No personal information is loaded into the other pilot's flight plan form. The other pilot cannot make any changes to your aircraft or favorite flight plans.
Where can I learn more about self-briefing?

We also recommend that you "practice" briefing for a period of 5 to 10 minutes a day as your schedule permits, whether or not a flight is planned. The intent with this strategy is to build comfort, muscle memory, and a practical understanding of how the weather varies from day-to-day.
