The position also required at least four years in a supervisory position directly related to the coordination of complex surface transport operations in the international environment or a United Nations entity. (...) He does have two years of supervisory experience directly related to the coordination of complex surface transport operations in the current post, however the JO calls for four years minimum…15 31. (...) My responsibilities for Transport among others included overall management and coordination of UNMIN surface transport operations of its vehicle fleet, as well as formulation of policies controlling the use and safety of the fleet within UNMIN area of operation.

In this case, the approach surface. Presently, this surface extends up to distance of 15 kilometres. (...) In order to reduce the length, additional surfaces will need to be introduced. Slide 6 The data used in reviewing the surfaces confirm that it is possible to raise the slope of the surfaces. (...) OLS is now made up of two sets of surfaces: Obstacle Free Surfaces and Obstacle Evaluation Surfaces.

ICAO SARPs Definition of Obstacle free zone (OFZ): The airspace above the inner approach surface, inner transitional surfaces, and balked landing surface and that portion of the strip bounded by these surfaces, which is not penetrated by any fixed obstacle other than a low-mass and frangible mounted-one required for air navigation purposes.
