10. Don’t be afraid to call ATC and use the transponder when lost or uncertain of your position - overcoming your embarrassment may prevent an infringement, which may in turn prevent an Airprox (or worse).
2. Aeronautical information
The definitive source is the UK Integrated Aeronautical Information Publication (UK IAIP) www.ais.org.uk
Static information, updated every 28 days, containing information of lasting (permanent) character essential to air navigation.
. GEN General operational, legal and administrative information.
. ENR En-route airspace information
. AD Generic & AD Specific Information pertaining to UK licensed aerodromes.
AIP Supplements (SUP)
Supplements are temporary changes to the AIP, usually of long duration, containing comprehensive text and/or graphics.
Aeronautical Information Circulars (AICs)
AICs are notices relating to safety, navigation, technical, administrative or legal matters. These are issued whenever it is necessary to promulgate information that does not qualify for inclusion in the AIP or as an AIP supplement. Circulars are published on Thursdays every 28 days. Each AIC is numbered sequentially by calendar year, eg 16/2004, 1/2007.
Each AIC is also given an additional ‘colour continuity number’ that appears after the serial number, e.g. Yellow 113, Mauve 211.
AICs may be reissued or amended, in which case text insertions or amendments will be marked by a thick vertical bar or an arrow facing the text in the margin. Deletions will be marked by an arrow facing away from the text.
In order to facilitate easy selection of AICs they are colour-coded as follows:
. White - Administration matters, eg licence examination dates, new publications or amendments to publications, course fees and charges.
. Yellow - Operational matters including ATS facilities and requirements.
. Pink - Safety related topics.
. Mauve - UK Airspace Restrictions imposed in accordance with the Temporary Restriction of Flying Regulations.
. Green - Maps and Charts.
