Not sure why the plane circled around and went the other way. https://globe.adsbexchange.com/?icao=abf375
Hi EE - Possibly to gain altitude for other traffic that was conflicted. I see others doing the same later, maybe to stay out of the way of SFO inbounds? A look at the charts for approach and departure routes might be helpful.
I noticed another one doing it. I looked at the terrain map on Gmaps and the mountains aren't as high as what the plane is at when it turns its' first turn.
i see lots of inbound planes landing towards the airport further north. so i guess the airport further south has the planes from it gain more altitude to get over the flight path of the planes landing to the airport to the north. i find it surprising there's three big airports so close together. must be a busy place.
Wanna see busy? Look at NYC with JFK, LGA and EWR being so close together. Back in the Day, I would sometimes drive from BOS to NYC rather than get stuck ine delays by taking the shuttle flights.
oh wow. i didnt' know there was that many over there. is all those airports maxed out on people and planes or are they spread out evenly?
I forgot TEB, the bizjet airport closest to NYC. I used to work near that one in the '80's. Yup, ATC has to spread the planes out and maintain FAA vertical and horizontal separations so it's quite a ballet to keep it all moving in normal times (wind direction, typical approach and departure patterns, higher altitude through traffic overhead etc.). Then throw in runway closures for repairs, change in wind conditions and the rest, it is a day to day mess. My home field is HNL. Right now 8L/24R is closed for improvements, so almost every plane is landing on the diagonal NE runway (forget the name) usually reserved for cargo flights, biz jets and it also has a GA shorter runway adjacent. What a mess. Several neighbors are pilots and bitch about triple the taxi to gate times. In another thread I noted an unusual holding pattern into HNL that was due to 12-14 fighter planes landing on that same runway. At least commercial 12 flights ran racetrack delay courses just NE of me, while waiting for the fighters to land in 3 groups of 4. I got visuals on 2 groups and saw them as TIS-B hits while they taxied to Hickham. Are you feeding BTW?
wow. i wish i could be plane spotting and see fighter jets and get pics of them. other then a staged air show. thunderbirds don't count. No I'm not feeding. been wanting to for a year but i can't afford the equipment. I've been pitching data from my ATCS server to the aggregator for ATCS Monitor for the trains for over 10 years. but the RR's are converting their ATCS and other protocols to a new protocol called ITCM on the PTC system. that cannot legally be monitored or easy to monitor if we could, because 220mhz radios are impossible to come by on the used market. and they can use multiple freqs for data packets so you would need one for each freq. sucks because us railfans are going into the dark. there's less radio traffic too. hot box detectors on big mainlines don't talk except on defect only. Seems we'll be railfanning blind and can't watch where the trains are coming and going on the computer screen anymore. Then in the big cities you can't follow the train on the screen to see what route it takes through the city and line it's going on. at least with aviation we can still watch the planes on the computer screen. pity i can't do plane spotting around here because the nearest big airports are 70+ miles away at Wichita KS and Kansas City. but even those airports are kind of boring compared to the action i've watched on the live video feeds on YT of the Phoenix Sky Harbor and LAX and SFO.
Setting up a feeder doesn't require any special knowledge. It's all just entering a few scripts. As for expense, the Rasbperry Pi's are in short supply and are being scalped. For the feeder I built for mobile use, I used an Orange Pi 3 LTS that came with a case, heatsink and power supply that cost $60 on Amazon and a $35 SDR dongle from ADSB-X. Add a home brew antenna and a TF card and you would be ready to go.
so even on amazon the prices are too high? you think they will go down at some point? what is a good price for them? as far as an antenna I'd rather have a high gain antenna that is already built that would be of better quality then i can build to maximize the signals.
Yup, A Raspberry Pi 4B with 2 GB of memory sells for about $40 from the maker, if you can find one. Things are so bad that the distributors have them on allocation and they sell out in seconds. There is even a website that tracks when they become available and will send you alerts which doesn't help me in Hawaii because they are sold out by the time I wake up. Amazon stick is always much higher as they are being scalped by third parties. So that's why my latest feeder is based on an Orange Pi 3 LTS, which is similar but not a Raspberry Pi. A good antenna is the unit sold at the ADSB-X store here. I have several.
