Description
This unit involves the skills and knowledge required to inspect and report on obstacle limitation surfaces (OLS) and includes performing a visual inspection of OLS, reporting obstacles in OLS and reporting the return of the aerodrome to the previous status.
Notes
Elements and Performance Criteria
1 Perform a visual inspection of OLS
  • 1.1 OLS are inspected visually and objects or structures that have or may become obstacles are identified
  • 1.2 Obstacles in OLS are removed in accordance with workplace procedures
  • 1.3 Where an obstacle cannot be removed, a determination for the reporting, marking or lighting of the obstacle is made in accordance with workplace procedures
2 Report obstacles in OLS
  • 2.1 Where an obstacle cannot be removed, information required for calculation of declared distances and supplementary take off distances is collated in accordance with workplace procedures
  • 2.2 All relevant authorities or organisations are notified of the status of obstacles and declared distances for obstacles
  • 2.3 All relevant authorities or organisations are notified of location of obstacles, where there is no requirement for reporting declared distances
  • 2.4 All relevant authorities or organisations are notified of appropriate marking and lighting requirements using suitable means of communication
3 Report return of aerodrome to previous status
  • 3.1 OLS are inspected visually to confirm removal of temporary obstacles
  • 3.2 Relevant authorities or organisations are notified of removal of temporary obstacles, using suitable means of communication
