These charts are produced by the National Geospatial-Intelligence Agency (formerly National Imagery and Mapping Agency (NIMA), formerly DMA) and were formerly distributed by NOAA.
Tactical Pilotage Charts (TPC Charts)
The Tactical Pilotage Chart supports high-speed, low-altitude radar, and visual navigation of high-performance tactical and reconnaissance aircraft from low to medium altitudes. It is designed to assist close air operations by providing visual and radar navigation information. The knowledge of map symbology becomes important to understand cultural features depicted on the chart.
The library retains select editions of TPC charts (1980-2003). NOAA no longer produces and distributes these charts. Since October 2000, responsibility has been transferred to the Federal Aviation Administration (FAA). For current editions, please contact the FAA's Distribution Division. Historical versions of the Tactical Pilotage Chart series may also be available via University of Texas Libraries.
Jet Navigation Charts (JNC Charts)
JNC charts are in shelf files next to the TPC charts. The primary purpose of the Jet Navigation Chart is to support high-altitude computer assisted radar navigation/bombing by strategic aircraft. Information considerations are selected to support celestial, radar, and dead reckoning navigation.
Like TPC charts, the library retains select editions of JNC charts (1998-2002).
