A010 requires certificate holders to use specific sources for obtaining weather reports and forecasts. A010 defines the Virtual Operator's approved sources of aviation weather reports and forecasts, including those involving adverse weather phenomena.

Include the following statement in the preamble: "The certificate holder conducting <insert applicable regulatory compliance> operations shall use the sources of aviation weather information described in this operations specification."

The following sources of weather are approved for all operations:

1. For operations within the 48 contiguous United States and the District of Columbia, A010 automatically authorizes the use of the NWS (National Weather Service) or a source approved by the NWS to provide weather reports within the 48 contiguous United States and the District of Columbia. Sources approved by the NWS can be found in Volume 3, Chapter 26, Section 1, paragraph 3-2048. These specific sources do not have to be listed in A010.
2. Virtual Operators are automatically authorized to use the POSCON live map (weather layer) for adverse weather detection and avoidance.
3. Virtual Operators are automatically authorized to use METARs, TAFs, ATISes, ASOSs, and AWOSs provided by POSCON through our services APIs.

This subparagraph should be used to identify each additional weather source approved for the certificate holder.
