How should ratings and rating endorsements be linked together in the proposed licence format? There are two rating endorsements (Terminal Control (TCL) and Oceanic Control (OCN)) that can be attached either to the Approach Control Surveillance (APS) or the Area Control Surveillance (ACS) rating. The licence template establishes in point IX a place for ratings and another one for rating endorsements, with no link between these two. The question is how to differentiate between the two: to which rating (APS or ACS) corresponds each one of those rating endorsements (TCL or OCN)? Is it necessary at all to make the distinction?
The ‘pairing’ of the current rating(s) and rating endorsement(s) is visible in point XIIa, which lists the ratings and rating endorsements according to the unit endorsements. Apart from that, there is no need to distinguish further.
