1. Chapter 5 proposal
AIS-AIM SG #8

2. Initial ideas Dealing with temporality of the data
Maybe also with the product/service update requirements
There is no major text to be changed in the existing Chapter 6 on “AIRAC”
Problem of FMS data (probably more than 80% of data) that need to be pre-processed and for which the 28 day advance notice is required.
Idea of increased frequency of AIRAC cycle dates (every 14 days) not included. No clear operational benefit identified
Existing need to be changed to provisions stating that the information shall be received 28 days in advance of the effective date
Temporality (effective date, time of change, temporary amendments, etc.) shall be embedded in the data

3. Three options AIRAC cycle requirements only
As in the current Annex 15
Aeronautical information update - focus on products
Including AIRAC requirements
Also including details for how to update each product / service
This means that CH 5 is more logically situated after CH 6
See: [edit online] AMDT 38 - New Chapter 5 - Working version
Aeronautical information update – focus on update type
Generic requirements for the publication of permanent changes, temporary changes, changes of long duration with extensive text and graphics
This also means that CH 5 is more logically situated after CH 6
