AIP amendment cycle
Amendments are currently issued every 56 days. This follows the ICAO AIRAC cycle, which is every 28 days but every other cycle is missed out. The first amendment in 2008 will be effective on the 14th of February, further amendments will follow at 56 day intervals.
Amendments are numbered annually starting at 1. So the amendment with the effective date of 14th February 2008 will be no 1/2008.
In certain circumstances an amendment may be issued at an interim 28 day period.
Holders of the AIP will only receive amendments if they subscribe to the Amendment Service. (See AIP Shop for more on subscribing)
Amendments are dispatched to be with subscribers at least 28 days before they are due to become effective.
Thus, if an amendment has an effective date of the 24th November 05 it should be delivered to all subscribers before the 26th of October 05. (In cases of extensive change to airspace or procedures this period is extended to 56 days)
AIP amendments may not be issued every 56 days. A NOTAM is issued on the effective date of each 28 day AIRAC cycle, stating when the next amendment will be issued.
The amendment service for all volumes includes AIP Supplements and AIC. In addition, subscribers to Volume 2 & 3 will receive the IFR Enroute charts when they are updated twice yearly.
No amendment service is currently available for Visual Navigation Charts and this is not anticipated.
