What is a primary source for pilots to obtain preflight weather data?

A primary source for pilots to obtain preflight weather data encompasses various services that provide essential weather information, helping pilots make informed decisions before flying.

Leidos Flight Services is a major provider of weather briefings and flight planning services, tailored specifically for aviators. They deliver timely and accurate weather updates, alerts, and forecasts that are crucial for preflight preparation.

The National Weather Service (NWS) is also a vital resource, as it is the official source of weather data and forecasts in the United States. The NWS provides comprehensive weather maps, warnings, and advisories, which are indispensable for pilots assessing weather conditions.

Foreflight is a popular flight planning application widely used by pilots. It integrates weather data from various sources, allowing users to access real-time weather information, including radar, METARs, TAFs, and more, directly from their devices, making preflight planning more efficient and user-friendly.

All of these entities play significant roles in supplying weather information, indicating that pilots have multiple reliable sources at their disposal for obtaining the necessary data to prepare for their flights effectively.
