This thread is for discussions surrounding LBA's Rwy's: 14/32, all Aircraft Stands and all LBA Taxiways.

Discussions relating to construction must go into the Infrastructure Developments thread.

Re: Leeds Bradford Airport - Runways, Aprons and Taxiways.

Following on from the TCX and LBA General thread:

Concorde Lover:

It does seem that the last time the Runway was re-surfaced was back in 1985, Although since then it has bound to have had a few repairs or sections replaced due to cracking for example, although i am not 100% sure regarding this.

One of the major differences between asphalt and concrete paving is the fact that asphlat paving is considered to be a "flexible" material, whereas concrete is considered "rigid". This has great implications in the way that the material transfers applied loads to the ground that supports it (the subgrade). Concrete, theorectically, acts as a rigid beam and will provide a more uniform load distrbution to ground below. Asphalt has a tendancy to transfer the load directly down to the ground below at the point where the load is applied. Therefore, in the extreme case of a plane weighting several tons impacting with the runway, you would prefer a material that will distribute the load to prevent the ground below it from settling due to the high loading. Another problem with asphlat is "rutting" and temperature stability. Heavy planes continually following the same routes along the taxiways and runways could cause premature rutts in an asphlat surface (you see this in bus stations too). Also, as temperature increases, asphalt becomes softer and more prone to damage not only from the loading applied by the plane, but also from the wheels grinding into the surface as the plane is turning etc...

Thanks for that Concorde Lover, a very interesting read!

I can see both sides of the argument here. The runway does need repairs on various spots of the runway but to actually re-surface the runway would mean closures on and off all the time.
Some might ask; does the runway actually need resurfacing at all?! I know preferably the airport would want a Asphalt runway like nearly every other airport in the UK, despite the issues on asphalt raised in Concorde Lover's analysis.

TCX:
We don't know if the A321 braking 'problems' are actually hindering possibilities of TCX basing an A321 at LBA - I agree with White Heather as well, that I would also prefer 2 A320's instead of 1 A321... you never know White Heather, TCX are heading towards an all Airbus fleet.....?!?!

Wasn't it one of the reasons given 'that the runway needed resurfacing' was a reason for selling the airport?

Re: Leeds Bradford Airport - Runways, Aprons and Taxiways.

I don't have any facts as such regarding the resurfacing of the runway but I understand the runway is being resurfaced on a gradual basis, basically as and when slabs require replacing.

Although most airports in the UK use Asphalt as the main runway surface, concrete runways are used widely else where around the world. Most of the Canadian airports use concrete and many even have underground heating for through the winter months.

In some LBA bumph I have there's a write-up about the runway and it states that concrete was chosen for it's excellent breaking and drainage characteristics.

Here's a paragraph from Wikipedia regarding runway surfaces.

The choice of material used to construct the runway depends on the use and the local ground conditions. For a major airport, where the ground conditions permit, the most satisfactory type of pavement for long-term minimum maintenance is concrete[clarification needed]. Although certain airports have used reinforcement[clarification needed] in concrete pavements, this is generally found to be unnecessary, with the exception of expansion joints across the runway where a dowel assembly, which permits relative movement of the concrete slabs, is placed in the concrete. Where it can be anticipated that major settlements of the runway will occur over the years because of unstable ground conditions, it is preferable to install asphaltic concrete surface, as it is easier to patch on a periodic basis. For fields with very low traffic of light planes, it is possible to use a sod surface. Some runways also make use of salt flat runways.

Re: Leeds Bradford Airport - Runways, Aprons and Taxiways.

All things considered, the councils did put in the Airport Masterplan, which is said to be 'still active', that a extension to the runway would be needed. Granted this was some years ago, but even if Bridgepoint did want to extend, not that they can afford it, the councils would probably grant them permission!

After the current phases of the redevelopment of the terminal consideration has to be given by Bridgepoint, or whoever else are the owners of the airport, to an extension of say 300 metres to the exisitng runway. There are too many restrictions currently in relation to aircraft types, weather conditions, load factors etc for the airport to be anything else but the second division of UK airports. I'm sure more major airlines would be attracted once we have the new terminal and a runway that could handle all types of equipment. We are always going to be hoping that airline xyz may open routes but in reality this is never gping to happen until all restrictions are removed. We will never rival the size of the airport over the hill but we may just be able to tempt some of their routes into LBA.

Re: Leeds Bradford Airport - Runways, Aprons and Taxiways.

I agree dmrogers.

Another topic that needs to be considered, which I keep stressing within the forum, is the need for more aircraft stand, and apron space. As many members on here have stated, there is a very little space, over-night, for aircraft and airlines to start basing aircraft on an over-night basis.
The airport are eager for airlines such as; Jet2, Ryanair and easyJet to all start expanding from the airport, but all these can't be on 'W' legs, so the airport would also need to start looking into this.

The ideal position for new apron space would be along TwyN, opposite B & C. The councils did also envisage the need for more stands, in this very position by around 2010/15 so more-or-less spot on for that person. :hatsoff:

Re: Leeds Bradford Airport - Runways, Aprons and Taxiways.

Well this has appeared on the latest NOTAMS for LBA and it refers to B777/200.

Can anyone shed any light as to what happening, I wonder if PIA are to upgrade?

Re: Leeds Bradford Airport - Runways, Aprons and Taxiways.

Is there a degree course I can do so I can understand what all that jargon means on the NOTAM??? Sounds promising though.

[White Heather]

Re: Leeds Bradford Airport - Runways, Aprons and Taxiways.

Does this indicate perhaps that IF PIA were to upgrade to the 777, it would be a 200 series (which I understand they don't have many of, but that they are better suited to LBA), rather than the 300 series? If not, why doesn't this NOTAM include the 300 series too?

 

[pilot_737]

Re: Leeds Bradford Airport - Runways, Aprons and Taxiways.

Basically this is saying that 'B777/200' has been added to the aiport's operational textual information.

http://www.ead.eurocontrol.int/eadbasic ... -06-02.pdf

If you look at the above PDF and go to page 7, section 2 'Ground Movement'. Under 'D' it reads:
d. The marked centre-line turning circle for larger aircraft (B767/300 or A310/A300) using the Runway 32 turning pad may only be achieved using up to 52° of nose wheel steering. Additionally, there is no straight section of the centre-line parallel to runway centre-line before commencement of the 180° turn onto the runway centre-line.

It will now read The marked centre-line turning circle for larger aircraft (B777/200, B767/300 or A310/A300)

I wouldn't read too much into this to be honest.

Re: Leeds Bradford Airport - Runways, Aprons and Taxiways.

All it does is proves that the Boeing 777-200 is cleared to operate from LBA which we were pretty certain of before.

It does appear that steps are being taken to prepare for the arrival of the Boeing 777-200 so fingers crossed.

Re: Leeds Bradford Airport - Runways, Aprons and Taxiways.

I was just wondering, can a B737-800 park on Stand 7? I have only ever seen Airbus A320's normally use it, but haven't seen a B737-800 on it before.

Thanks,
Tom.

 

[lbia]

Re: Leeds Bradford Airport - Runways, Aprons and Taxiways.

Yep, Thomson have used stand 7 and more recently Ryanair have even used the air bridge.

They must have used it for free. They've been in a dispute with AENA about having to pay to use air bridges at Alicante without an option for remote parking.

Never EVER thought i'd see the day.

Re: Leeds Bradford Airport - Runways, Aprons and Taxiways.

Ryanair B738 was parked at airbridge (think it was 8) at 11.45pm yesterday. I believe it was the inbound AGP. We had to be bussed from stand 22.
