Runway heating can pay for itself in two years, says report

SOARING COST IS NO EXCUSE

FOR CLOSURE OF AIRPORTS

I am not privy to airport costings but the seemingly needless grounding of British-based planes during the ongoing cold spell is a soar point with me (pun intended).

Because it could all have been avoided if Heathrow, Gatwick and other UK airports had  heating under their runways.

But that would not be ecnomically viable,  did I hear someone say? The cost would be astronomical and would have to be passed on to those who utilise the airports.

Presumably that means  the thousands of us who stand around interminally analysing the ‘Cancelled’ and ‘Delayed’ messages on flight departure boards. In Spain as well as the UK,

Presumably, then, the £12 car-park fee my daughter paid to pick me up at Manchester Airport last week is NOT astronomical. And  it’s reasonable to charge nearly a fiver for a sandwich - and that goes for Alicante as well as British flying space,

Captive audiences will always be ripped off. The only way the public can counter the profiteers is not to buy extortionately priced goods. But when you are starving and stranded miles from nowhere, what alternative is there?

When you think about it, it is actually in the interest of the  airports to ground passengers because they have to eat. And that means buying those gold-plated sarnies and £4 bottles of water.

It might be a good idea to start charging for using the airport loos as well, as mooted by Ryanair’s penny-pinching boss. That’s gotta be worth a bog-standard million quid a week, surely.

I’m not surprised there’s no rush to invest in underground heating – and the predicted vast expense provides a good excuse. Of cours, Britain’s increasingly deluded bureaucrats also assure us  we don’t have enough sub-zero weather to justify runway heating. Which is nonsense if the past couple of climate-changing years are anything to go by.

So how expensive would it be to heat the runways? Well, an executive study at  St Cloud State University in Minnesota concluded that using geothermal heat can prevent the build-up of ice and snow ”and once installed, such a system could pay for it self in as little as 2-5 years.”

The report also slammed current methods of trying to keeping runways open, maintaining: ”Both chemicals and snow-ploughing vehicles have adverse effects on the environment as they contribute to pollution.”

I am no engineering expert, so have no idea whether such a system is feasible for UK airports. But something MUST be done about the seemingly endless delays passengers are suffering these days.

Keeping airports open at all times has to be a priority. BAA, who own Heathrow and Stansted among others, are predicting a 15 per cent rise in income next year to £1.12 BILLION. So they are not exactly skint. 

But do they really care that it’s becoming a bonus for passengers to get to their destination on the scheduled day, let alone on time?

The heat is on – or rather off if you’re in the UK. Whether those who make the decisions have the hot-water bottle to do anything about it is another matter.

And just how are they going to put in this undersurface heating? It would mean digging up the runways. Runways on average are three feet thick. Gatwick, 1 runway, 12000 feet long. Heathrow 2 runways each 12000 feet long. It would involve closing the airports for probably around a year and that's just the runways...what about the taxiways and parking stands..? the roads for the vehicular traffic involved in aircraft servicing..? Sorry but digging up an entire airport is a non starter.

The runways aren't the problem. They are easily cleared its all the other elements of the infrastructure. The costs involved are out of all proportion to the benefits. Just for information all the major European airports are affected not just the UK.

Quite frankly anyone who turns up at a snowbound airport, knowing it to be subject to substantial delays deserves to get stuck. Have they never heard of telephones? Or websites...the message from all airport operators and airlines is contact the airport /airline before starting out.

Someone asked "have we taken a step back in time so far as runway clearance is concerned" and my answer is probably yes BUT it's largely thanks to the Environmentalists. They create far more problems than they cure. They moan continuously about the emissions from Jet Engines at high altitudes and it is they who have successfully managed to ban the use of such machines at ground level so the use of the old truck mounted twin-jet sno-blow machines is a definite no-no.

Also there is the question of the de-icing chemicals used these days; the various water authorities dislike the run-off from the runways getting into the normal surface drainage and the underlying water table. There is also the point that the chemicals used are highly corrosive to aluminium and cause premature aging of airframe structures.

So, whilst it is damaging to big airline corporation profits it is ultimately more cost-effective to just ground all aircraft movements and let nature take it's course with assistance from ploughs, scrapers and rotary brushes.

As for runway heating all very nice but unless you have a large store of geothermal energy to rely on the costs involved are astronomical. Think of the millions of gallons of hot water that would be needed and the consequent electricity bills

Numerous scientific studies have shown that the system has to be operational at least 5 days before any snowfall to overcome the thermal inertia of 3 feet of concrete. The installation of such a system would entail closing and ripping up runways and no airport authority is going to sanction that kind of expenditure. Given that in fact the runways are the least problem and the easiest to clear mechanically, there is still the question of the support taxiways, service roads, aircraft dispersals, parking stands, etc, etc.

Taking Gatwick as an example there is also the question of the transport infrastructure. The railways in the mid-Sussex area are just as badly affected and the trains stop running at the drop of a hat. The M23 / M25 are highly liable to closure in snow, so people cannot get into or away from the airport even if the airport itself had every snow clearance device known to man."

Someone suggested that East Midlands Airport had runway heating. I can find no evidence to support this...

continuing my quote

"East Midlands Airport does NOT have runway heating; they were just lucky that they weren't affected by the very heavy snowfalls experienced in other parts of the UK. They are however very environmentally aware...see this link

Prior to coming out here I worked at Bournemouth Airport for 15 years and in all that time I think we closed just twice and we were open again for business within 24 hours handling diverted traffic from all over the UK and Europe. Bournemouth did close for a while this winter due to the snow but again was reopened for business (such as it was given that the rest of Europe had ground to a standstill!) within a very short period of time under 12 hours as I recall.

No airports in the UK have runway heating and only a couple in the States are so equipped. The ones that are so equipped in the States are operational USAF bases that suffer long periods of snow every winter.

There is no environmentally friendly, cost effective solution. All costs would have to be passed onto the customers ultimately and given that the majority of homeowners / holiday-homeowners out here use airlines such as Ryanair and Easyjet because they provide a cheap form of transport, the impact of such costs would probably lead to those operators moving away from 'modified' airports to avoid paying the higher charges; passing on the costs to the customer would make them no longer cost effective. However in moving away from say Stansted and Luton they would lose customers anyway so its a Catch-22.

Far easier and ultimately far more cost effective just to shut down operations and wait for the weather to change." end quote.

The press are quick to blame Heathrow for the prolonged closure and a praising Gatwick for their not so prolonged closure...it's all a question of resources and future planning. Something which didnt do anyone aany good anywhere in Europe this time as the virtually the whole of Germany, France the Netherlands and Belgium came to a standstill!
