Sectional Aeronautical Charts (1:500,000)- Designed for visual navigation of slow or medium  speed aircraft. Topographic information on these  charts features the portrayal of relief and a judicious  selection of visual check points for VFR flight.  Aeronautical information includes visual and radio  aids to navigation, airports, controlled airspace,  permanent special use airspace (SUA), obstructions,  and related data.  b.  VFR Terminal Area Charts (1:250,000)- Depict Class B airspace which provides for the  control or segregation of all the aircraft within Class  B airspace. The chart depicts topographic informa- tion and aeronautical information which includes  visual and radio aids to navigation, airports,  controlled airspace, permanent SUA, obstructions,  and related data.  c.  En Route Low Altitude Charts- Provide  aeronautical information for en route instrument  navigation (IFR) in the low altitude stratum.  Information includes the portrayal of airways, limits  of controlled airspace, position identification and  frequencies of radio aids, selected airports, minimum  en route and minimum obstruction clearance  altitudes, airway distances, reporting points, perma- nent SUA, and related data. Area charts, which are a  part of this series, furnish terminal data at a larger  scale in congested areas.  d.  En Route High Altitude Charts- Provide  aeronautical information for en route instrument  navigation (IFR) in the high altitude stratum.  Information includes the portrayal of jet routes,  identification and frequencies of radio aids, selected  airports, distances, time zones, special use airspace,  and related information.  e.  Instrument Approach Procedure (IAP) Charts- Portray the aeronautical data which is required to  execute an instrument approach to an airport. These  charts depict the procedures, including all related  data, and the airport diagram. Each procedure is  designated for use with a specific type of electronic  navigation system including NDB, TACAN, VOR,  ILS RNAV and GLS. These charts are identified by  the type of navigational aid(s)/equipment required to  provide final approach guidance.  f.  Instrument Departure Procedure (DP) Charts- Designed to expedite clearance delivery and to  facilitate transition between takeoff and en route  operations. Each DP is presented as a separate chart  and may serve a single airport or more than one  airport in a given geographical location.  g.  Standard Terminal Arrival (STAR) Charts- Designed to expedite air traffic control arrival  procedures and to facilitate transition between en  route and instrument approach operations. Each  STAR procedure is presented as a separate chart and  may serve a single airport or more than one airport in  a given geographical location.  h.  Airport Taxi Charts- Designed to expedite the  efficient and safe flow of ground traffic at an airport.  These charts are identified by the official airport  name; e.g., Ronald Reagan Washington National  Airport.  (See ICAO term AERONAUTICAL CHART.)  AERONAUTICAL CHART [ICAO]- A representa- tion of a portion of the earth, its culture and relief,  specifically designated to meet the requirements of  air navigation.  AERONAUTICAL INFORMATION MANUAL  (AIM)- A primary FAA publication whose purpose  is to instruct airmen about operating in the National  Airspace System of the U.S. It provides basic flight  information, ATC Procedures and general instruc- tional information concerning health, medical facts,  factors affecting flight safety, accident and hazard  reporting, and types of aeronautical charts and their  use.  AERONAUTICAL INFORMATION PUBLICA- TION (AIP) [ICAO]- A publication issued by or with  the authority of a State and containing aeronautical  information of a lasting character essential to air  navigation.  (See CHART SUPPLEMENT U.S.)  AFFIRMATIVE- Yes.  (See AUTOMATIC FLIGHT INFORMATION  SERVICE - ALASKA FSSs ONLY.)  (See AIRSPACE FLOW PROGRAM.)  (See AIRCRAFT HAZARD AREA.)  PCG A-3  AFIS- AFP- AHA-
