Which document must a Remote PIC check for airspace restrictions?

The correct document for a Remote Pilot in Command (PIC) to check for airspace restrictions is NOTAMs (Notice to Airmen). NOTAMs provide critical information about the status of airspace, including any temporary restrictions, changes, or hazards that may impact flight operations. They are constantly updated and can include a wide range of information such as airspace closures due to events, restrictions due to military activity, or temporary flight restrictions (TFRs) due to natural disasters.

While sectional charts do provide valuable information regarding airspace boundaries and regulations, they may not reflect the most current restrictions that could be issued after the chart was published. Weather briefings are essential for understanding meteorological conditions but do not specifically address airspace restrictions. The Airman’s Information Manual offers comprehensive guidance and regulations for pilots but is not designed to provide real-time updates on airspace status.

In summary, checking NOTAMs is crucial for ensuring safety and compliance with the latest airspace restrictions prior to any unmanned aircraft operation.
