Freeing up Runways, Again

In a blog post last month, I wrote about the probability that important European runways will be oversaturated in the future. In the March, 2009, edition of Aerospace America, Philip Butterworth-Hayes makes the same point in his article "Running out of runways".

WITHOUT MAJOR IMPROVEMENTS TO THE
continent’s air transport infrastructure,
Europe will find that its busiest airports
and airways will be saturated by 2030—
effectively capping the growth plans of
European airlines and the demand for
new aircraft.

In a recent study called Challenges
to Growth, the Brussels-based air traffic
management agency Eurocontrol predicts
that annual flights within Europe
will rise from 10 million today to 20.4
million by 2030. Even if all the current
airport capacity development strategies
proceed as planned, these figures still
mean there will be 2.3 million flights a
year (nearly 10% of the total) for which
there will be no room in Europe.

The point I made in my previous post and which I reiterate here is the need to utilize existing runways for the one purpose that is absolutely essential: the take off and landing of large, long distance flights. VTOL craft should be used for all shorter haul, regional flights that carry less than 100 passengers and travel less than 100 miles (1610 km), and for all smaller general aviation planes. VTOL craft will need only vertipads for landing, which can be at airports, but also can be in many other, more convenient, locations. The large Boeing and Airbus airplanes of current and future designs will have the runways to themselves, and this will relieve the pressure to build more runways, saving the substantial sums of money that are required.

The Business of Innovation

The senior editor of General Aviation News, Thomas Norton, has a column in the February 6th, 2009 edition of that magazine called "What Business Are You In?". He makes these points:

What should we do when our comfortable niche either vanishes or becomes so small that it no longer supports our business? That's exactly what is happening at many companies, not all of them small, in the aviation community.

If we are to adapt to our circumstances, we need to be thinking more like the Wright brothers, James Watt, Alexander Graham Bell and and number of genuine innovators.

I could not agree more with Mr. Norton. I have felt for some time that general aviation, depending as it does on long take off and landing (LTOL) aircraft, is not offering product with maximum appeal. So long as airports are needed for both ends of a flight, takeoff points and destinations are limited. It's true that many GA pilots in the past and present fly for recreational reasons; but the cost of part time use of airplanes is high, and with there being increased concern about environmental impacts of carbon based fuels, it is not likely that recreational flying will provide a larger and larger market in the future. Airplane manufacturers could have products with increasing appeal if those airplanes were not dependent on airports, and thereby could provide much more convenient air transportation.

Those who have read my blog before know that I am a big fan of vertical take off and landing aircraft (VTOL). Although helicopters are VTOL, they are not ideal from my perspective. They have limited horizontal speed and require frequent maintenance. My company, Aeromobile Inc., has spent a number of years in developing a fixed wing airplane that takes off and lands vertically. We call it the Arc Wing VTOL Airplane. A sketch of it is below:

To me, innovation for general aviation means developing airplanes that fly as fast as the ones we have now, are as well made and safe as the ones we have know, are as pilotable as the ones we have now, but have VTOL capability. Such airplanes could offer true point to point transportation, and air taxi type services would blossom as the beginning and the end points of a flight were almost unlimited. Many other aviation services currently the venue of rotorcraft, like search and rescue, police patrolling, ship to shore flights, fire fighting can also become the venue of fixed wing aircraft. The GA manufacturers of the past and today have accomplished much in the efficiency, safety and capabilities of fixed wing craft. I think that innovation into taking off and landing vertically is where research is most needed, and where the greatest payoff will be.

I invite all GA aircraft manufacturers to contact Aeromobile Inc. to work with us on our innovative and business expanding technology.

Freeing Up Runways

Pierre Sparaco discusses the lack of runways at major European airports in his article "Runways Are Forever" in the Aviation Week & Space Technology journal of February 2, 2009. Due to cost and environmental concerns, airports in the UK, Germany and elsewhere have moved very slowly to add new runways, leaving the existing ones too crowded today and even more crowded in the future.

The larger commercial airplanes of the future - the Airbus A380 and the larger Boeing craft - will need long runways. They and their somewhat smaller Airbus and Boeing bretheren are long take off and landing aircraft, and such aircraft are the best way to tranport large numbers of air passengers long distances. But, much of the air traffic today consists of smaller airplanes, which still need runways, and therefore compete with the large jets for runway space. These craft, which usually travel less than 1000 miles (1600 km), could and should be replaced by VTOL airplanes. Our Arc Wing VTOL airplane can be scaled up to replace "regional" jets and air taxi services. VTOL craft would not need to use runways at all, allowing the existing ones to be dedicated for large jets.

And, the issue is not just with adding new runways. In some regions - New York, for example - new aiports have been proposed, to alleviate the crowded runways at existing airports. With VTOL regional airplanes and VTOL taxis, new airports will not be as necessary. And, the financial and environmental disagreements over adding a new runway are quite tame with the opposition generated over an entirely new aiport. It would make much more sense to make the best possible use of the runways we have, leaving them for just the large jets. Let's develop VTOL technology. It has so many advantages, and reducing runway overuse is among them.
