IFR Aeronautical Information

This series of seven volumes is updated every 56 days and provides aeronautical information primarily related to the IFR arrival or departure phases of flight and comprises the following flight procedure types:

• Instrument Approach Procedure (IAP)
• Diverse and Standard Instrument Departure (SID)
• Standard Instrument Arrival (STAR)
• Noise Abatement Procedure
• Visual Approaches
• It also contains ground operations information such as parking areas and de-icing facilities along with Aerodrome and Taxi Chart

This chart series provides flight crews with information to facilitate navigation along ATS routes in compliance with air traffic services procedures. It is intended for use in the low level airspace structure (below 18,000 feet ASL). The LO chart series, comprising 10 charts, depicts aeronautical radio information, airways system, controlled/uncontrolled airspace structure, special use airspace, communication stations and selected aerodromes. It is used for IFR route planning and inflight navigation.

This chart series provides flight crews with information to facilitate navigation along high level airways and routes in compliance with air traffic control procedures. They are intended for use in high level airspace (18,000 feet ASL and above). This series comprises six HI charts depicting aeronautical radio information, high level airways structure, controlled/uncontrolled airspace structure, special use airspace, communication facilities and selected aerodromes. It is used for IFR route planning and inflight navigation

This chart series provides flight crews with information to facilitate IFR navigation in the terminal area of aerodromes in compliance with air traffic services (ATS) procedures. It is intended to assist in the transition from the enroute portion of the flight to the arrival portion, or from the departure portion to the enroute portion, at those terminals where the airspace structure is relatively complex. The TAC depicts aeronautical radio information, airways system, controlled/uncontrolled airspace structure, special use airspace, communication stations and selected aerodromes in congested areas at a larger scale. This information is in addition to what is displayed on the enroute series and instrument procedure charts.
