Flight Paths

Ozarks1

Is there a way to check the flight paths over Dublin and at what times they are suppossed to be used and to check if planes are turning too early over populated area instead of flying out the further or at too low an altitude?

Where are you located that you are noticing aircraft flying where they shouldn't?

*cough* check OP's post history *cough cough*

L1011

A similar situation in the UK of bulk reporting by one person turned out that they were automating it off schedules and they ended up sending reports for flights that never operated. Not saying that's happening here though

Noise Abatement Procedures including published runway selection priorities are published in section 2.21 of this document

Bear in mind, ATC are entitled to issue instructions to aircraft contrary to these procedures where they deem it necessary.

You can buy some tinfoil in the local shop for your new hat.

You can check the actual flight paths taken on flightradar24.com. With a cheap subscription you can check back in time quite a considerable period.

Not sure where or how you would find out whether they were the routes supposed to be taken.

I believe altitudes on flightradar are given based on standard pressure settings so you would need to make a correction based on the actual barometric pressure at the time to get a correct altitude reading.

Candamir

Should probably have checked out those flight paths and the airport location before you bought the house OP!

Is it not based on the aircraft own flight data as broadcast through ADS-B?

Yes, but based on standard pressure.

well whatever it's based on, it's the same data that ATC gets, and if it's good enough for ATC, then I'd say it's good enough for the OP

ATC systems correct the received data for the reported QNH though

I see. Is there likely to be a significant difference then at Dublin? ~70m above sea level....

... or have I already answered my question?

Nope. You didn’t answer your question.

Difference could easily be a few hundred feet on any given day.

Why do you ask? Are you the person who made all those complaints from Ongar?

Occams Razor seems to indicate so...........

smurfjed

Yes, but based on standard pressure.

Our transponder readout is the same as our altitude indicators which are based on a set pressure, either QNE/QNH/QFE.

I would have thought that FR gets that same altitude

smurfjed

Associated the OP with someone in Ongar which was wrong. I apologise.

OP have you tried setting up a decibel recorder on your phone to justify the claims?

Im thinking someone who complained 545 times in 31 days isnt going to be interested in something like objective proof.
Comment directed at the complainant rather than the OP of this thread.

I had to google the location of ONGAR, I would be very surprised if an aircraft was making more noise that the N3 motorway.

Of course they haven't. They're too busy making spurious complaints to have the time to do something logical.

Not me ! Just enquiring really if there was a way to know at what times the different flight paths are used or does it vary and if they stick to the flight paths.

I dont think I made any claims, just a question around how the flight paths are used. I have better things to do with my time then sending hundreds of complaints. I didn't even know about those reports. But thanks all for jumping on me for asking a simple question.

Stovepipe

The flight paths used depend on weather, wind, runway in use( which can change at any time) and the ultimate destination of each aircraft after takes off. In recent times, a lot of the older flight paths were deleted or changed and now the approach and departure routes are sometimes shorter to save time and fuel. As an example, aircraft approaching Dublin from the direction of the Irish Sea, North or South take a turn inland to join the approach glideslope for Runway 28, closer than they used to. They don't fly over any housing and save time and fuel, compared to the old routine of joining much further out. Operations are also different for slower turboprops , which will fly at a lower altitude than jets, as they climb up to the altitude they will use enroute. Turboprops will also turn onto heading earlier than jets, which often have to climb to a minimum height before they can turn onto their headings. Noise is a constant consideration for all commercial aircraft and most airports operate some kind of noise restriction; the aircraft must climb to a minimum height over certain areas, must reduce power and climb at a shallower angle, may not operate into or out of certain airports after certain times and even in some cases, may not land or even make an approach after certain times. Aircraft are also restricted from operating near bird sanctuaries, military training areas, areas of outstanding natural beauty and other special sites unless they are over a minimum altitude.

Transponder transmits the level based on standard pressure, this is then corrected by ATC systems to the local QNH for display on screen. If it transmitted the level based on a possibly incorrect pressure setting, both yourself and ATC could be working off the same mistaken information. Transmitting based on standard pressure allows ATC to spot a discrepancy while checking your Mode C on contact.

smurfjed

Reading through our manuals, it says noting about the transponder only transmitting the altitude based on "standard" pressure.

"The DADC processes the air data inputs and provides digital and analog outputs to the: * ATC Transponders

Then we have...

The tuning adapter provides an interface between the transponder control unit and the TDR-90 transponder by
converting the control unit ARINC 429 serial data into the format that the transponder requires. It also provides
an interface between the DADCs and the transponder for pressure altitude data conversion."

Do you have reference on this that i can read?

Not the most readable document, but ICAO Annex 10 Volume IV

3.1.1.7.12.2.2 The information pulses shall be automatically selected by an analog-to-digital converter connected to a pressure-altitude data source in the aircraft referenced to the standard pressure setting of 1 013.25 hectopascals.

Note.— The pressure setting of 1 013.25 hectopascals is equal to 29.92 inches of mercury.

Thanks for the "light" bed time reading

Obviously someone obsessed by this issue, with an average of 17/18 complaints per day. The ironic thing this is that 10/28 has been operational for a very long time before the Ongar area was built.

I'm beginning to think that person is so thick they're actually complaining about the traffic at Weston, not DUB. They probably don't know the difference between a C150 and a B737. There is no real noise problem over this area.

Very rarely get any traffic over Ongar from Weston, the closest you’d get it would be St.Catherines Park. The RWY28 take off flight path goes near enough to direct over Ongar with the departure turn directly over it, arrivals onto RWY10 are usually directly down the N3 on the opposite side of Ongar, down over Mulhuddart graveyard etc. Not that I have a problem with any of that, i’m in the Dublin 15 area my whole life (right under the flight path) 10 years in Ongar now and they turn literally over my house between 3-5000ft hardly ever hear or notice an aircraft going over anymore.

In all fairness the person concerned appears to be completely obsessed by aircraft noise.
To have the time and the where with all, to log 17 to 18 individual complains per day, 7 days a week, for an entire month and to continue to log sucessive high rates of complaints each month. Is someone who to my mind is obsessional and in possible need of assistance.
Calling them "thick" is not really necessary.

AnRothar

QNH below the transition altitude.
Standard pressure above the transition level.

This is pretty much my reading of it.

Sorry, I had a brain fart. For some reason I was mixing up Ongar with Adamstown. I take it all back. I guess I'm the one who's thick...

The OE is about 4km north of Ongar, and the vast majority of 28 traffic will cross it above 3000ft with thrust back to climb. I suppose they’ll get the odd early left turn, but I can’t really see how it could be a massive problem there. Not to the tune of 545 times a month anyway!!

arccosh

It's something I miss about Dubin funnily enough.... being close to the flight path... the quietness where I am now can make it feel strange at times

Bummer1234

That one from ongar seems to have a serious issue....Does the DAA look into these individually?...

Head out to this ones house and investigate it and the poor statistics lad who compiles this report will be a lot quieter...I lived in ongar before and never had a issue will noisy a/c.

Dunno whether it was worth it's own thread but yesterday on a flight from Lisbon to Dublin FR7329 about halfway through while looking out a port window a what looked like an ANA 787 (a very amateur guess) came under our plane from starboard. It looked close but is there any way to find out how close for free?

Minimum vertical separation is 1000ft, and I can guarantee you it was no less than 1000ft. Try looking back on flight radar and you might be able to find it

Kevin Finnerty

I can see its flight details and a playback of its flight path but nothing on planes in the neighhbourhood. 1000ft looks nothing in the air, just never saw it mid air before. And the speed of it all.

Just had a look at the DAA report and were I live is not even mentioned :mad: even though I'm right under the flight path, Must start sending in some complaints I also noticed that Hansfield had 1 complaint which is right beside Ongar and other estates within the Clonee area not mentioned.

Is there a similar APP for Dublin?

Which has more letters, left or right?
Which has more letters, port or starboard?
Which has more letters, red or green?

All the answers are on the same side.

Now that we’ve cleared that up, would you like your rattle back in your pram?
