The Romance of Airport Codes

LHR – JFK don’t those six letters cause some excitement to even the most seasoned traveller, there is still just a little romance left in air travel.

Romance here is the “feeling of mystery, excitement and remoteness from everyday life” as opposed to love !

For me part of the romance comes from the Airport codes themselves, those three letter IATA codes are a shortcuts to destinations known and imagined and each have a personal resonance. Many of the codes also have an antecedence that  provide a fascinating window into the early days of air travel.

LHR London HeathRow is both the starting point of most of my travels but also a link back to a childhood spent on the roof of the Queens Building watching British Airways Tridents, VC-10’s and 747 classics departing to destinations I never expected to visit in my lifetime.

Of those childhood destinations and even today New York’s JFK the airport named after president John F. Kennedy was always a destination that sparked my imagination, the destination of those Pan Am Clipper 747s and of course Concorde it was just such a  glamorous destination.  The name of course was the product of tragic history,  the original name of the airport, Idlewild also sounds wonderful but was named after a local Golf Course.

New York’s second international airport, New Jerseys’ Newark has the very functional code of EWR – NEWaRk.

LCY or to those who use if often Lucy

As an alternative to the giant that is Heathrow,  Londons CitY Airport, LCY provides a wonderful contrast harking back to the golden days of air travel when every flight began with that exciting trip up a set of stairs to the aircraft door, Jet-Bridges are just not the same.

LCY is loved by many  is often just called Lucy as a mark of familiarity.

London’s GatWick LGW, Paris Charles De Gaul CDG and of course HELsinki’s HEL are obvious in they derivation, but why is Chicago’s mega airport ORD and Los Angeles LAX ?

The use of Airport codes was originally introduced in the United States for Meteorological reporting  with airports making use of the existing two character city codes developed by the National Weather Service, Los Angeles was LA for example.
It was clear that this system was not going to work with the massive increase in Air Travel after the Second World War so in 1947 a three letter code system was introduced and to pad the existing codes a letter X was often introduced so Los Angeles became LAX, and PortlanD PDX .

A similar approach was taken in Canada where the two letter codes used by Canadian Railways were given a Y prefix so VancouveR’s code VR became YVR, and  QueBec’s code QB YQB.

Most interesting of course are the codes which don’t seem to make sense,  DCA Washington’s District of Columbia Airport  is perhaps not obvious but makes sense but why is the larger international airport in Washington IAD ?  Originally the Dulles International Airport DIA was too similar to DCA so it was simply reversed DIA becoming IAD !

Other codes which don’t seem to make sense are often the result of name changes as Airports have grown or cities have themselves changed name, so CMH the airport serving Columbus Ohio was once just the Columbus Municipal Hanger and of course Mumbai was a city once called BOMbay.

My personal favourite is Chicago’s ORD, very few peoples top airport, we might not feel so negative if it had retained it’s original name ORcharD Field !

The Last Concorde

Back in June of last year I visited the now disused Aerodrome at Filton to visit Concorde 216 G-BOAF as part of my quest to visit all the Concordes in a year. Then Alpha Foxtrot was a rather sad sight parked in a remote corner of the airfield visible only from a Car Showrooms car park…

Todays visit find conditions somewhat improved.

Alpha Foxtrot is now the centrepiece of the Aerospace Bristol visitors centre and museum which opened last week the result of a £19 million investment, in addition to a building specifically built to hold the Concorde there are three beautifully restored aircraft sheds  holding other notably exhibits including some Bristol helicopters and the nose section of a Bristol Britannia.

Alpha Foxtrot looks in very good condition and is displayed using some clever 3D projectors including this one which explains how the innovative variable geometry intake made sure that Concorde’s Olympus 593 engines always received subsonic air despite travelling at Mach 2.

There is also a small display of Concorde artifacts including test pilot’s Brian Trumshaws Overalls !

Alpha Foxtrot is now up there with East Fortune’s Alpha Alpha as the best presented Concorde and Aerospace Bristol is well worth the visit.

If you can’t link to it… does it exist ?

“If a tree falls in a forest and no one is around to hear it, does it make a sound?”

So goes the well-known philosophical thought experiment,  however rather than a discourse on observation and perception I’d like to hijack the experiment for an argument I have been making on and off for the last couple of years and which was  well summarised in a tweet summarising my point last month..

Does information published on the web which is not easily linkable actually exist ?

Well of course if I chose to publish my large spatial database of whatever using a Web Feature Service or some other application server the data actually exists, but as far as users of the web does it exist if I cannot find it using web search or more importantly as far as the way the web works cannot link to it?

This issue of making the so-called Deep Web more discoverable is still challenging , efforts such as the sitemap protocol have had only limited impact.

I would argue for the geospatial community in particular we need to take a more fundamental look at how we make information accessible and linkable on the web.  We need to start from the basic use case, common if you think about it but radical it would appear in the GIS world..

I need to let people link to each record in my spatial database and to share that link..

This actually requires perhaps a much more granular approach to making spatial data available, something that nearly got started with OS Mastermap but which for many issues was never fully implemented.

Rather than publishing online a database of railway station locations in the Netherlands and expecting a user to then query the database for  “Amsterdam Centraal Station”,  publish the database giving each record a URI so for example Amsterdam Centraal Station becomes;

https://brt.basisregistraties.overheid.nl/top10nl/id/gebouw/102625209 

Now this is something I can paste into an email, tweet or even share on Facebook !

Kudos to the Dutch Kadaster for taking this approach and providing this example, Ordnance Survey you could do the same ?

This approach also results in such data becoming part of the “mainstream” web indexable and searchable, but I argue the key benefit is the “linkability”

The Spatial Data on the Web best practice document, something of course I recommend you taking a longer look at provides many excellent practical pointers to taking this type of approach.

Maybe really this is just an issue of semantics rather than publishing spatial data should we be talking about sharing spatial data ?

The sign of the times..

You might notice a redesign of my site today, nothing major really a little less clutter hopefully, but the reason for the change is really behind the scenes. This site is now using the encrypted version of the web protocol https. Once only a requirement for sites taking payments and banking increasingly all types of websites are now making use of encryption and in the near future the chrome browser will label sites not using https as “Not Secure”.

Personally I think this might be overkill for a site such as this, but I can easily imagine people becoming concerned with such warnings.

A sign of the times…

Much as I expected it was in some ways a rather sad process of course we would all rather see Concorde flying rather than in museums, but the fact that a few of the airframes seem almost forgotten and unloved in a few locations is rather depressing.  

Highlights in terms of the best preserved and presented aircraft are pair at Le Bourget, Alpha Alpha at East Fortune and Alpha Echo at Bridgetown.  

At the other end of the spectrum are of course Alpha Bravo in the car park at Heathrow and historic Concorde 02 at Orly !

Seeing Concorde remains an emotional experience, even if you have not been lucky enough to see one fly, there is something so special about the design or at a more fundamental level just the shape.

Of course Concorde was an engineering marvel but perhaps it’s real appeal is that it is the manifestation of the paper dart that we as children imagined all aircraft to be !

Concorde 101 G-AXDN, Duxford, England

So my last Concorde completing my year long quest to visit all eighteen remaining airframes… Concorde 101

Or is it 01 and what are these numbers all about anyway…

Well is started quite logically, the two Prototype aircraft were 001 and 002, the pre-production aircraft of which this is an example would be 01 and 02 and the production aircraft numbering would start with airframe number 1, then 2, 3 etc.

Then is was realised it would be easier if all manufacture numbers contained three digits, so 01 and 02 became 101 and 102 and the production aircraft started with 201.

Just to add to the confusion there are the type variant numbers, a number associated with a particular customers version of an aircraft, so Air France Concorde were variant 101 and British Airways variant 102.

Anyway 101 had a short but distinguished life, completing 273 Flights totalling just under 575 hours as the British Development aircraft, quite different to the prototypes and much closer to the production aircraft in design. 01 is the fastest Concorde to fly achieving a speed of 1,480MPH (Mach 2.23) in March 1974.

101 is preserved within the Airspace Hangar at the Imperial War Museums Duxford facility which is a rather full of interesting aircraft making photography rather difficult. A recent innovation is the monthly dropping of the Nose of 101 on the last Sunday of each month  following restoration of part of the hydraulic system… Something I intend to go back to see !

It is possible to walk through the aircraft and view much of the test equipment which is currently being restored by the wonderful people of the Duxford Aviation Society.

Concorde 214 G-BOAG, Seattle,USA

Alpha Golf, first flew in 1978 but did not enter service with British Airways until 1980 as it remained otherwise unsold by British Aerospace. There are a few pictures of the airframe as a “whitetail” online, looking rather sad without any livery.

Upon entering service in April 1980 water contamination in the hydraulic system resulted in an air intake failure which in turn caused multiple engine unstarts at Mach 2 ! no doubt spilling a little champagne and ending up with a £1 million repair bill.

After this problematic start Alpha Golf went onto operate just over 5000 flights until retirement in 2003 flying the very last passenger service from New York on October 24th that year and along with Alpha Echo and Alpha Foxtrot landing together at Heathrow to  mark the end of Concorde Service.

A very emotional occasion, I know as I was there !

Alpha Golf Heathrow October 24th 2003

A month later Alpha Golf flew to New York and then on the 5th November with special permission flew from New York to it’s final destination of Seattle in a record time of 3 hours 55 minutes flying Supersonic for a hour over northern Canada and setting a East to West Transcontinental record which stands today.

For the next 13 years the airframe was stored outside the Museum of Flight alongside it’s other large aircraft exhibits including the prototype Boeing 747 and a Boeing VC-137 “Air Force One”. Last year a roof structure was completed bringing Alpha Golf under cover and not a moment too soon as the aircraft has clear signs of damage caused by the Pacific Northwest weather.

And so on to the last Concorde to visit… Concorde 01 G-AXDN at Duxford..

Concorde 212 G-BOAE, Bridgetown, Barbados

Alpha Echo is a gem, beautifully preserved and very well looked after by a small but enthusiastic team, you could imagine the flight engineer selecting REFLIGHT/START Switch for Engine Number 3 to START and the Olympus 593 spooling up.

Concorde 212 G-BOAE was completed in Filton in early 1977 and entered service with British Airways that summer. Over the next 26 years Alpha Echo operated just over 7000 supersonic flights before finally landing at  Grantley Adams International Airport in Bridgetown on 17 November 2003.  This final flight, taking  just under 4 hours from London, reached the maximum certified height of 60,000 ft.

Barbados is the forgotten regular destination of Concorde,  from the mid 1980’s until the retirement of Concorde in 2003 it was possible to make a Saturday day trip the Caribbean from Heathrow.

With time differences playing in your favour an arrival at 9am in Barbados would mean you arrived before you took off! A few hours later after a quick lunch and paddle you could return on the same aircraft arriving back in London just before 9pm.. Of course most of the holiday makers onboard paying around £6500 for the ticket stayed rather longer than a few hours, but the route did much to cement Barbados as a luxury holiday destination.

The home of Alpha Echo is the “Concorde Experience Barbados” which is a purpose built hanger, with some displays of Concorde artefacts very similar to the Scottish home of Alpha Alpha at East Fortune. A really well made and informative video is projected onto the fuselage which explains many of the technical advances that Concorde represented in simple terms.

The experience is open Tuesday to Saturday and the entrance fee is $40 (BBD)

So my quest continues, sixteen done only two to go…
