JAA Minima page is inserted by Jepp for aerodromes where the main apch charts feature minima calculated by different methodology.
JAA Minima page should be used by all operators whose (CAA Approved) minima methodology conforms to Old Appendix to OPS 1.430.
By EU-OPS, each operator must provide the applicable minima to its pilots. If customer demand indicates that main minima table should display different values than 'JAR-OPS', Jeppesen would normally include the page.
To have an approved minima methodology is a legal requirement as well as to provide the minima to pilots.
Commonly, the minima types used for Jepp plates around here are:
'PANS-OPS'
'JAR-OPS'
'Standard'
One of the latter two applies for you, check OM-A/C. Out of personal interest, did you guys transition to New Appendix to OPS 1.430 or not yet?
