Notams and TFRs are of utmost importance. Trike pilots, as well as other pilots must familiarize themselves with all notams and TFRs before flight. Due to rapidly changing conditions, you should obtain notam information from flight service and/or DUATS just prior to flight. There are many temporary flight restrictions (TFRs) throughout the country. In addition, you will see there is a “blanket” TFR notam. The “blanket” TFR notam does not supersede any other TFR notams.
National Airspace System Changes
The main references for changes to the National Airspace System (NAS) are the Aeronautical Charts and the Airport/Facility Directories. Most changes to the NAS meeting NOTAM criteria are known sufficiently in advance to be carried in these publications. When this cannot be done, changes are carried in the Notices to Airmen publication and/or the Service A telecommunications system as a NOTAM D item.
FDC Airway NOTAMS
National Flight Data Center (FDC) NOTAMs reflecting airway changes are carried as Center Area NOTAMs (CAN) on the NOTAM(D) circuit. CANs are NOTAMs issued on airway changes that fall within an ARTCC’s airspace. CANs are in FDC format and issued by the U.S. NOTAM Office.
NOTAMS in the Notices to Airmen Publication
NOTAM D information printed in this publication is NOT included on the Service A circuit.
FDC NOTAMs reflect changes to Standard Instrument Approach Procedures (SIAPs), flight restrictions, and aeronautical chart revisions. The date and number of the last FDC NOTAM included in this issue is indicated on the Table of Contents page. This ensures that FDC NOTAMs issued after the Notices to Airmen publication cutoff date can be identified.
Temporary Flight Restrictions (TFR)
Temporary Flight Restrictions (TFR) are tools used by the Federal Aviation Administration (FAA) to restrict aircraft operations within designated areas.
