Withdrawal of CAP 624 Air Traffic Controller – Performance objectives

We will shortly be withdrawing the CAP 624 series of documents. The elements covering ratings (ADV, ADI, APP, APS, ACS) will be reviewed with the aim to republish at a later date.

In the meantime Air Navigation Service Providers and ATC training organisations are advised to retain those references in their training documentation and, if required, retain copies of the performance objectives to cross- check against during this interim period.
