Does it have to be radar? Can it use ADS-B?
- scblock 1y agoThe FAA document says "sensor-based" but every installation I have seen in the US uses radar.
- buildsjets 1y agoLittle cropdusters and sport aircraft are who the anticollision lights are designed intended to protect, and many of them are not ADS-B equipped. In the US, ADS-B is not required below 10,000 feet and when more than 30 miles away from the 30 largest commercial airports.
- estimator7292 1y agoThis is a safety measure. You can't rely on ALL aircraft having functional (or installed) transponders. You must actively sense incoming craft because they don't always politely announce themselves.
- wiml 1y agoAt small unattended airfields, you can sometimes turn on the field lights by transmitting on a particular frequency (as if you were calling the non-existent tower in quick succession). https://www.aopa.org/news-and-media/all-news/2017/march/flight-training-magazine/how-it-works-lighting https://www.aopa.org/news-and-media/all-news/2017/march/flig... (Of course, in this case it works because the pilot already knows the airfield is there.)
