Best Notam plotter

[Bert Stiles]

Has anyone any preferences or handy pointers to a good notam plotting site?

For a circuitous x -cty the AIS "narrow route brief" can use a forest and doesn't enable a plottable print out as far as I know.

The "Notam Check" effort gives a reasonable plot but there doesn't seem to be a way of eliminating either the notam code or translation when printing the text - you have to have both and another forest. The "unplottable" items can also spring some surprises.

Haven't tried the "Notam Plot" site mainly 'cos I'm fairly interested in stuff happening out to sea and a programme optimised for gliders shouldn't be too good at that.

Any others? - One where you put your route in and a map appears with notams plotted and annotated would be ...... ideal.

OK I don't expect much.

Not sure why you'd say it doesn't work out to sea, and I don't know about the gliders connection, but I use it routinely and find it excellent. I also read the AIS stuff online just to double-check.

There is another web based utility called GA Book or something like that. Theres a link to it on Loops website. I tried it out @ Fly! It seems pretty good, although a little slow perhaps.

If you use the AIS narrow route for a VFR flight and define every turn point in your route before using something like a 10nm wide corridor (+/- 5nm) then unless you are doing a very long route there will not be many NOTAMS.

Yes there are a few unnecessary pieces of info eg why does the Southern MDA have to be NOTAMed throughout the whole FIR?....does a local Lands End Flight need to know about North Sea danger areas?

However, overall if you use the AIS software to it's full extent, it is quite good.

NOTAM plot will not ease your load because it will not plot all the NOTAMS. It will give you a long list of the NOTAMs that it is unable to plot and you have to individually check each unplotted notam just in case it applies to your flight.

The ideal situation would be for NOTAM plot to be able to download a narrow route brief and then plot those thus creating a situation where the unplotted ones are of interest and can be read easily.

I find NOTAMPlot does ease my workload by helpging highlight the on-track nav warnings etc, and then I skim the written one from AIS as well.

Most of the problems with the AIS site stem from a lack of proper understanding of how it works, or indeed how the ICAO NOTAM system works. I speak as the AOPA representative on NOTAM matters and have had an unhealthily close association with them over the past few years.

Plotting NOTAM is a tricky job. ICAO requires that each NOTAM has a geographic centre and a Radius of Influence (RoI). Something affecting an entire FIR will therefore have a centre roughly in the middle of the FIR but its RoI will mean that the boundary, were you to try and plot it, was off of your chart so how do you plot it? Plotting works fine for things that cover a limited geographic area but has limitations when it comes to big stuff.

For the AIS Site:-

First off, make sure you use a Narrow Route Brief (NRB), not a Route Brief. The Route Brief gives you aerodrome NOTAM for your departure arrival and alternate a/d plus the ENTIRE FIR. The Narrow Route Brief by default gives you NOTAM affecting 10nm either side of your intended track and does not result in a forest being felled. You can further filter down the data by using the filtering tools on the site, for example changing the Traffic field to VFR instead of the default IFR/VFR and by changing the UTC Validity Period (if left blank you get NOTAM valid during a 48 hour period starting from when you press Submit).

If you want to cover a geographic area rather than a route (for example for a multi-sector route or a circular X/C try this technique:-

Look at your chart and find two a/d that straddle the area in which you intend to fly. Use the NRB and set these two a/d as the departure and arrival a/d. Adjust the "Narrow Route Width" to create a box either side of the line beweeen the two a/d sufficiently wide to cover you intended area of operations. Put the a/d you intend to use during the flight(s) in as alternates to make sure you get any a/d NOTAM affecting them.

I'll be happy to respond to any technical queries you might have.

Mike et al,

Thanks for the replies. I have compared results using the various systems and so far the Nav check system works best. The problem with the AIS narrow route brief is that there is no graphical presentation which would help the overall workload. This is despite the refinements you highlighted.

Your suggestion of creating a box by use of two airfields and a wide swathe is possibly helpful for some flights.

A typical x- cty (for my aeroplane) would involve VFR/IFR and could use the length or breadth of the FIR, I'm interested in conflicting activity out to about 20 nm either side of track to cover any little excursions I might make. Sometimes the return leg is very close to the outward leg and so that the area notams reappear again and hence the forest. With a graphical plot they only need to appear once.

As DFC said the "unplottable" features of the Notam check site mean that you have to scan these and relate them to your track. Generally these are frequency/SSR code changes but occassionally a very significant hazard (to me) is highlighted.

Mike - I thought No 1 AIDU used to provide a plotted version, but if it still exists it must be under subscription. Do you know any more?

Thanks again one and all for their contributions.

Quote; "Sometimes the return leg is very close to the outward leg and so that the area notams reappear again and hence the forest. With a graphical plot they only need to appear once. "

So, submit the request as though it is just for the outbound leg, but make sure the time period covers the whole flight time plus a bit, and just get them once. That's what I do.

The whole process takes me less than 10 minutes including editing down the returned list which is only about 2 pages-worth anyway - hardly what I call a forest. Sometimes I do two - one for the general area my gliding club uses for local soaring/bimbling, for which I normally edit out all but the most local nav warnings (we are rarely interested in RAC, Comms, etc.), and another for long out-and-return flights for me and one or two others. The second takes much less time than the first because I can delete all the repeated RAC and comms etc. stuff without reading them again.

The lack of graphical output from the AIS website is a problem, there is no doubt about it.

But, once you get used to it, it's difficult to find anything else which is better.

I tend to fly the same routes regularly, which makes things a little easier, because my Briefing Handbook contains saved queries for my regular routes. All I need to do to get Notams is amend the period of validity and review the query, then press Submit.

The output which comes back is not unduly long by any means. But every now and then, I come across a Notam which contains huge numbers of co-ordinates, which may affect my route. Or even a Notam with a single set of co-ordinates, but no place name or a name I'm not familiar with. I then have to get my chart out and plot these points on the chart - and that is far more time-consuming than getting and reading the Notams in the first place. A less diligent pilot might well decide it is not worth the effort......

The next best thing I've found is NotamPlot, which is a fantastic tool. My one big gripe about NotamPlot is the unplotted Notams. There is no way to filter out unwanted unplotted Notams. There are generally a very large number of these unplotted Notams, and most of them are IFR only. As a VFR pilot, if it were possible to filter the IFR Notams out of the unplotted list, this would probably make NotamPlot my favourite tool.

What would be nice is if the two could be combined in some way - so you get the query capabilities of the AIS website (not as user-friendly as it could be, but very flexible once you get used to it and returns a manageable number of Notams) combined with the graphical output of NotamPlot.

The AIDU NOTAM display system was on trial some years ago. There's some information on it here. Suggest you contact No 1 AIDU for more info.

I confess that when I see a NOTAM along the lines of:-

H0638/06 - AUS 06-04-0197/765/AS4 NAV TRAINING EXERCISE. 6 JETSTREAM ACFT WI AREA BOUNDED BY 5204N 00600W 5155N 00520W 5140N 00520W 5136N 00524W 5124N 00503W 5049N 00517W 5024N 00509W 5005N 00542W 4954N 00542W 4954N 00512W 4926N 00512W 4850N 00800W 5100N 00800W ORIGIN.

I wonder why they bother and I confess to not plotting it. Six aircraft doing a NAVEX between 500 ft and FL120 shouldn't really fall within the definition of what requires a NOTAM IMHO.

Being unable (or should that be unwilling) to comply with the rules of the air is most definitely a hazard.

The bits that anoy me are the North Sea danger area being given such a radius of influence that they appear on every narrow route briefing even one from Lands End to 1nm down the road.

I know that this is a blatent plug but you may find that http://www.funfly.co.uk is a useful pre flight workspace.
It was a webpage that was originally set up for myself for when I was away from my home computer but quite a few others have found it useful so I have tarted it up and starting to push it for general use.
Some if the referencies lack a bit of content but it is early days and I am hoping that people will offer me their own websites to include.
Anyway it don't cost nuffink, so please feel free to have a look.

Yes one does wonder why (does the Navy issue Notices to Mariners saying "Navigation Exercise - participating vessels may not be able to avoid crashing into other shipping"?) However in practical terms one can do no more than one should be doing anyway, keeping a good lookout. In my yoof this was referred to in one Nautical Almanac as "the ordinary practice of seamen". I preferred not to ponder on what this might consist of.

[IO540]

I've been using the ais.org.uk narrow route briefing (NRB) for about 3 years now. During that time I have read so much stuff on these pilot forums about people having to wade through "too much stuff" but never understood what the problem is.

I think there is a massive lack of understanding in this area. PPL training doesn't help - I bet few schools teach ais.org.uk and much fewer will tell you about the NRB.

For starters, the NRB doesn't pull out too much stuff. If you plot a flight from the UK to say Greece, you will get perhaps 5 pages but a quick scan shows that nearly all of it is cr*p, for example notams from Greece saying they control their airspace and not Turkey, closely followed by notams from Turkey saying they control their airspace and not Greece. Then you might get a load of reports of unlit obstacles along the length of Italy. So what? It takes 1 minute to spot the rubbish. On flights within the UK (perhaps 99% of a UK PPL's activity) there is far less rubbish.

Next, ignore the stuff which was put in there to cover somebody's ar*e. Most notams are there just for that reason. Nav warnings (NAVW) are in that category. A NAVW might tell you about some military activity in an area specified by a horrid coordinate list. Do you have to plot it? NO, the military fly potentially everywhere anyway, ducking microlights and all the other low level PPL traffic. This stuff is irrelevant. The sky is big! If you fly at 600ft you are more likely to hit some parachute with a lawn mower on the back of it than a Harrier.

What matters is temporary restricted areas, temporary Class A, inop VORs, inop instrument approaches, closed runways, and stuff like that. In 3 years and some 500 hours and trips up to 800nm per leg, I have never had a notam list that took longer than a few minutes to look at, and that includes the bizzare Greek/Turkish stuff.

I also don't remember the last time I had to plot coordinates. Maybe once or twice. That's why I never bothered with a graphical plotting program. It would hardly ever get used.

The NRB seems to be a well kept secret!

There is zero prospect of anything changing. GA doesn't even feature on the aviation horizon, and IFR traffic tends to ignore en route notams anyway - it flies under radar control. The system is international and there are countless people around the world stuffing reports into the system about duff bulbs in lamp-posts.

[FlyingForFun]

The NRB seems to be a well kept secret!

That's very true. Other than people who read these forums, go to seminars, or have instructors who tell them about it, most people wouldn't know that the Narrow Route Brief is what they are looking for, even if they stumble across the AIS website. (And remember that, although there are doubtless a few instructors out there who don't show their students how to get NOTAMs, maybe even don't know themselves, there are also plenty of PPLs who have little involvement with flying schools and aren't in a position for instructors to show them.)

Perhaps the biggest single improvement which could be easily made would be to rename it, and make it more obvious (not just by the name, but also by the location of the link) that this is the "normal" briefing.

I find Notam map by Andy Hall an excellent aid
it is freely downloadable from http://www.notam-map.co.uk//index.html

[Bert Stiles]

I'll have a look at Notam map as well. Thanks.

As for IO540's assertions - well, you're entitled to your opinion. The military would disagree with you for a start - that's possibly why they still employ people to stick pins in maps. Most can't afford that luxury. There are those who have been checking Notams for all the continents and oceans of the world for several decades for one reason or another and some systems are adequate for what they need, but sometimes they need improvement (DIY obviously, as the authorities wouldn't be interested). Yes, much of it is irrelevant to one user or another, but there are flights for which a forest WILL be generated - it just takes imagination to realise that. I seek experience of the UK systems to merge the information for my uses.

BS.

[IO540]

Disagree with what?

That they fly anywhere anytime anyway?

Many years ago, long before I started flying, the RAF was bigger than it is today, and did a lot more flying. There was no ais.org.uk back then, so how did pilots (those that go places and didn't spend their days hanging around flying schools/clubs) find out this vital information without which they would surely collide with an RAF aircraft?

They didn't, and it didn't matter.

The sky is big, the RAF navigates for most part visually (they really are tremendously traditional in this respect, which is why I wonder what capability the RAF would have if they ever had to do something big for real, but that's another matter) and they look after themselves. They get a lot more of a radar service than PPLs do. The front line jets also have radar.

But today's RAF could not muster enough planes on a given day to create a statistically significant collision risk. You are far more likely to hit a parachute with a lawn mower attached to it

If you can get a radar service, ask for it. They might give you an FIS only but (assuming you have a transponder, mode C, which is a big assumption) they will separate other traffic from you.

If you fly through an AIAA then obviously call them up.

The NAVW notams are IMV worthless. It's somebody covering their ar*e.

[Bert Stiles]

What proportion of airproxes involve the military? - the Cat A ones ? If there were no notams for their activities would there be the same number, more or less ? You would argue the same number. I would argue more. We differ.

BS.

NotamPlot is excellent, but as Aussie Andy pointed out, always double check with the AIS website.
