Flightradar24 (and other trackers) Thread Part IV

There was a discussion back in the day regarding the title. At one point there were 2 separate flight tracking threads.
We settled on “flightradar24” as it was the app/website that was most widely known/used.
Novices would recognise the name when looking for info, experts would recognise the intent even if they used a more involved app/site.

I’ve no problem though if people think it should be renamed to “Flight Tracker Thread”.
Don’t think anyone else would either.

Thoughts below maybe.

Works ok for me. Maybe add "(all flight trackers)~ to the title ?

Flightradar24 (All flight trackers included) Thread Part IV

Around 00:30 this morning, a Cargolux B747 went overhead here in North Dublin at FL300. It was far noisier than the EI 330's that pass over at half that height enroute to China. I actually thought it was on approach rather than enroute.

I'm sure this has been asked before, but I'm not going to trawl the thread....

Do Emergency Service aircraft not appear on Flightradar? I've often looked out my window at a Sikorsky flying overhead, and it's not on FR at all. Ditto with the Red/Yellow community Air Ambulance...never appears on FR.


Thanks.

In addition to robert6920’s answer above, these sites primarily use ADS-B signals received by members of the public with a scanner set up feeding transmissions received from the transponders to the site. Most commercial aircraft have ADS-B transponders, and they’re mandated to be installed in all aircraft, but the deadline has been pushed out a few times and there are a number of exemptions for certain types of aircraft and operators. ADS-B transmits the aircraft’s identity and position as calculated by onboard navigation systems.

Tracker sites can also use replies from Mode S transponders which provide the aircraft’s identity and altitude along with some other information, but not the position. The position is calculated by radar based on the time taken for a reply to be received, and which direction the radar was pointing when it sent the interrogation (plus measuring difference in time for separate antennas on the radar to receive the same reply in Monopulse SSRs). For flight tracker sites to get a position from these transmissions, they need 2 or more receivers to receive the same reply so the difference in time of arrival of the signal can be used to calculate a position.

FlightRadar24 blocks details of some aircraft they track (e.g. military or private planes whose owners have asked for them to be blocked). In some cases the aircraft won’t be shown at all, sometimes it shows only the type but not the registration or aircraft ID.

Of the Irish Coast Guard fleet, only EI-ICS (usually Waterford based I believe, but they do move around) has an ADS-B transponder, the rest have Mode S. As these aircraft generally operate at fairly low altitudes, the chances of buildings, terrain, curvature of the earth etc. blocking line of sight and thus the radio signals means they very often aren’t being picked up by enough ground stations to calculate a position. They all have marine AIS transponders that do transmit position though, so can usually be seen on MarineTraffic and other ship tracking sites.

Looking right now, there appears to be no general aviation traffic in Ireland, but the UK skies are packed.

Glad that some people are having fun.

It’s showing up on adsbexchange

EI-ICS showing up at Waterford (FR24)

Is there a site to view marine traffic ?

Air Corps 112 has landed on the main pad and 118 on the secondary pad, Air Corps 112 never shows on flight radar .

Have definitely seen AC112 on FR24 a few times, again it’s a matter of a Mode S signal being received by enough receivers to use multilateration to calculate a position.

The Air Corps aircraft have ADS-B but are no longer displayed on FR24 similar to other military aircraft. They do show on ADSBExchange. The Garda helicopters and the Casa don’t show either but the PC9s, the new PC12 and the Learjet (only shows type) do appear on FR24.

Spot on. As regards coastguard,EI-ICS,ICU,ICA and ICG all show now on flightradar 24 as will ICD in the next few weeks.

Yup, 3 of them visible now with ADS-B

Air India meant to be coming into DUB on 23 and 25 May for cargo.
AI1197 and AI1199 on flightradar.

They're repatriation flights rather than cargo

Azerbaijan B788 heading into DUB now from Baku.

EI9020 DUB-PEK departed DUB 20 minutes ago, now circling off Dublin bay. Whats up i wonder?

It's a test or other non-revenue flight. EXS do these regularly out of MAN as required and that callsign format is typical for such flights.

According to RTE, Door fell of Air Corps AW139 over Dublin school tonight.

Any know why this light aircraft keeps flying over Meath and Dublin for the past few days?

PH-LAW over the house today, must be hard work in that wind you can visually see the wings rocking all over the place every time they pass by
