To successfully complete a VFR flight current detailed airport and aviation information must be collected for the airspace, the departure and destination airports you will use.
Eurocontrol published a document containing tips to obtain aeronautical information before starting any flight.
Eurocontrol Guidance Notes
Excerpt from the document:
A major cause of airspace infringement is that some pilots simply do not know that the restricted airspace (airway, control zone, prohibited, restricted or danger area) is there, or that it must not be entered without permission.
Two types of aeronautical information are issued by national authorities. Semi-permanent information is published in the national Aeronautical Information Publication (AIP). Changes to information contained in the AIP and information of a short duration is published as a NOTAM (Notice to Airmen), which is distributed to major aerodromes by telecommunication, and is available to others by fax or on web sites.
