Information about radar procedures
Hello everyone,
After that accident in South America I would like to learn a little more how a radar system works and what ATC uses as procedures... Can someone give me some explanations?
- Is there any difference in terms of radar identification (resolution, for example) between a terminal radar (APP) and an enroute radar if an airplane is flying with its transponder switched off? Is it possible (if there is no altimetry) to have correct numbers in terms of heading and speed?
- Can an ATC controller identify a potential risk of collision between two targets but one has its transponder off? Does the radar system work precisely or sends any alert (visual or aural) if two airplanes are getting closer in this case? If not, in general, what are the recommended procedures: radar vectors? essential traffic information for both airplanes only?
Thanks,
Rgds
