The term Unit Competence Scheme (UCS) refers to an approved framework that outlines how a unit ensures its license holders remain competent. This concept is rooted in the regulations set forth by the European Union, particularly Regulation 2015/340. However, similar procedures are often found in other countries as well.
The UCS is essentially a document that details how air traffic controllers in a specific unit can demonstrate their required knowledge and skills for their roles. It is created by the Air Navigation Service Provider (ANSP) and must be approved by the relevant regulatory authority.
Each air traffic service unit has its own UCS, though units like control towers and approach control centers within the same country may have very similar processes, especially if they belong to the same ANSP.
The UCS outlines several key procedures, including:
-
Competence assessment: This section describes the methods used to evaluate controller competence, how often assessments occur, and who is qualified to conduct them.
-
Unit endorsement revalidation: This includes requirements for minimum working hours, maximum periods without exercising privileges, and necessary training courses, such as refresher training.
-
Continuation training: This specifies the content and duration of training needed to keep skills up-to-date.
-
Provisional inability: This refers to situations where a controller cannot work due to temporary conditions, such as stress or fatigue, while still holding a valid license.
-
Performance of instructors: The UCS also addresses the qualifications and responsibilities of practical instructors.
-
Process administration: This involves keeping detailed records, reviewing the UCS, and making amendments as necessary.
It’s important to note that the unit endorsement is a crucial part of an air traffic controller’s license, allowing them to work at specific positions, such as Heathrow Tower or Maastricht Control.
