In robotics, obstacle avoidance is the task of satisfying some control objective subject to non intersection or non collision position constraints. In unmanned air vehicles , it is an hot topic. What is critical about obstacle avoidance concept in this area is the growing need of usage of unmanned aerial vehicles in urban areas for especially military applications where it can be very useful in city wars. Normally obstacle avoidance is considered to be distinct from motion planning path planning in that one is usually implemented as a reactive control law while the other involves the pre computation of an obstacle free path which a controller will then guide a robot along.

Unreferenced stub auto yes date December 2009 Minimum Obstacle Clearance Altitude , or MOCA , is the lowest published altitude in effect between fixes on VHF omnidirectional range VOR Airway aviation airways , off airway routes, or route segments that meets obstacle like a building or a tower clearance requirements for the entire route segment. Within the United States, this altitude also assures acceptable navigational signal coverage only within 22 Nautical mile nm of a VHF omnidirectional range VOR . The MOCA seen on the National Aeronautical Charting Office NACO en route chart, may have been computed by adding the required obstacle clearance ROC to the controlling obstacle in the primary area or computed by using a TERPS chart if the controlling obstacle is located in the secondary area. This figure is then rounded to the nearest 100 foot increment, i.e. 2,049 feet becomes 2,000, and 2,050 feet becomes 2,100 feet. An extra 2,000 feet is added in mountainous areas, 1,000 in non mountainous. The MOCA is based upon obstacle clearance over the terrain or over manmade objects, adequacy of navigation facility performance, and communications requirements. The MOCA is always at or below the Minimum enroute altitude MEA , and may put an aircraft below air traffic control RADAR coverage and also below Minimum reception altitude MRA for navigation aids as a result, it is typically used only in emergencies, especially to get below icing.

An Air traffic obstacle is a tall structure which can endanger air traffic. Air traffic obstacles have to be marked in most cases with red and white colored markings and with aircraft warning lights at night. On larger structures blinking lights are required. An example of an air traffic obstacle is the air traffic control tower. In the past lamps similar to those used on lighthouses were sometimes used. There are still such lamps on Fernsehturm Stuttgart in Stuttgart, Germany. A fainter rotating light is on Blosenbergturm , Berom nster , Switzerland. A special method of marking was used at the mast of Deutschlandsender Herzberg Elster in 1939. On small poles near the mast multiple rotating skybeamers were mounted which illuminated the lens like structure on the top. Because of this no electrical installation was required on this mast.

Multiple issues unreferenced June 2009 cleanup June 2009 The Obstacle Collision Avoidance System OCAS is designed to alert pilots if their aircraft is in immediate danger of flying into an obstacle. OCAS uses a low power ground based radar to provide detection and tracking of an aircraft s proximity to an obstacle such as a Electric power transmission power line crossing, telecom tower or wind turbine s. This capability allows the visual warning lights to remain passive until an aircraft is detected and known to be tracking on an unsafe heading. This leaves the nighttime sky free of unnecessary light pollution thus decreasing public annoyance issues while improving the environmental habitat. OCAS is currently the only FAA approved Audio Visual Warning System Audio Visual Warning System AVWS approved in the National Airspace. OCAS is also the only AVWS approved by the International Dark Sky Association. OCAS is operational in the US, Canada, Norway and Germany. Overview Radar Coverage The OCAS system is designed to protect obstacles that are vulnerable to low flying aircraft. OCAS detects the ground speed , heading and altitude of approaching aircraft and determines whether it will adequately clear the obstacle. A configurable set of rules is applied to define and determine when to warn the aircraft, by which warning devise and signal depending on the calculated time to impact with the obstacle. Initial Warning Medium Intensity Lighting Once the initial threshold is met, the visual warning is activated. This capability allows the lighting system to remain passive in the off position the vast majority of the time thus preserving the dark sky environment while adhering to strict safety standards set out by the FAA. Secondary Warning Audio Broadcast If the initial warning does not result in the pilot altering the flight path, a programmable VHF radio broadcasts an additional obstruction warning directly to the cockpit.
