Te Radar s comedy often focuses on his interests in travel and history, and as a result his work has led to him presenting radio travel documentaries for Radio New Zealand . His 2004 radio show Dispatches from the Holy Lands , chronicling his travels through the Arab Israeli conflict resulted in the Television New Zealand documentary War Tourist Christmas in Bethlehem . In 2006 Te Radar fronted a three part documentary Hidden in the Numbers , which examined the changing face of New Zealand culture. This was followed by two further television series, Off the Radar and Homegrown . Off the Radar saw Te Radar s attempt at sustainable living, spending ten months working on a small allotment.

Radar control is a method of providing air traffic control services with the use of radar and Automatic Dependent Surveillance ADS B . The provision of air traffic control services without the use of radar is called procedural control . Separation In air traffic control, the risk of aircraft colliding is managed by applying separation rules. These rules require aircraft to be separated by either a minimum vertical distance, or, if for some reason they cannot be separated vertically, by a minimum horizontal distance defined by various means. One of the means of determining horizontal separation is by a controller observing the radar returns of the aircraft to be at least a minimum horizontal distance apart. This is the essence of radar control, and is known as Radar separation. Standard radar separation varies from airspace to airspace and country to country, however 3 nautical mile nms in Terminal Control Center terminal airspace and 5 nms in Area Control Center en route airspace are common minima. Maintaining separation In airspace with a lower amount of traffic, controllers will require pilots to navigate their aircraft on published routes which have been designed to be separated from each other. Controllers may require pilots to fly their aircraft at certain speeds or with certain minimum or maximum speeds to maintain separation between aircraft on these routes. When the amount of traffic in a particular volume of airspace reaches a certain level, it becomes impossible to keep aircraft following set routes separated, particularly in airspace where aircraft are climbing and descending and therefore level separation regularly cannot be maintained . In this case controllers use radar vectors , the issuing of headings to the pilots of aircraft on which the controller expects the pilots to fly their aircraft, to tactically keep aircraft separated in the sky. Much skill is involved in this type of control it is this type of controlling that has led air traffic control to be described ... more details

Image Slc 2 clear.jpg right thumb SLC 2 counter battery radar The SLC 2 Radar is a counter battery radar designed to accurately locate hostile artillery, rocket and ground to ground missile launchers immediately after enemy firing, and to support friendly artillery by providing guidance of counter fire. SLC 2 radar can also be applied in adjusting firing of friendly weapons or rockets. With slight modification to software parameters, SLC 2 radar can also be used to detect and track low flying targets such as light aircraft, helicopters and Remotely Piloted Vehicle RPVs . SLC 2 systems have sometimes been mounted on a Dongfang EQ2102 3.5 ton truck.
