First concrete SESAR achievements in 2011
On 08/03/2011, in SESAR's Palace, by steve
At the biggest international Air Traffic Management exhibition, ATC Global being held this week in Amsterdam, the SESAR Joint Undertaking presents the first components of the future European ATM system. The aim of this first SESAR Release is to group projects and validation exercises and to start delivering together with the 49 SESAR members and associate partners tangible results at a reindustrialization stage as of this year.
“SESAR is set to modernize air traffic management in Europe. Recent projections predict for Europe a doubling of flights by 2030 compared to 2009 levels. This equals 16.9 million movements; everybody knows that the current air traffic management system cannot cope with such an increase. SESAR is prepared to address this challenge by presenting first benefits for the aviation community this year, just as planned.”, says Patrick Ky, Executive Director of the SESAR Joint Undertaking.
Periodic releases
With the commitment of the private and public partners involved in the work program, SESAR will deliver results through periodic releases.
The first SESAR Release is the outcome of a thorough status review of the approximately 300 SESAR projects to see where early results can be achieved to
quicker serve the aviation world. Projects which are included in the 2011 Release will have been verified and validated in an operational environment to allow for a decision on industrialization and subsequent deployment.
With the first SESAR Release, the European ATM modernization program reveals initial components of the future European ATM system. The validation exercises will cover the areas of efficient and green terminal airspace operations, the initial 4D trajectory, end to end traffic synchronization, as well as integrated and collaborative network management. Concrete benefits will be achieved for airlines, pilots, airports, air traffic controllers, pilots, passengers and the environment.
Improved procedures, tool sets, prototypes
Through simulations, prototypes, shadow mode or live and flight trials, the SESAR members will perform 29 validation exercises all over Europe, the first of which have already taken place in February.

WorldFlight: driving virtual airspace to the max
On 02/11/2010, in Simulator world, by hoppie
On a sunny, crisp Sunday morning in Melbourne, Australia in the late 1990s, Matt Sheil raised the gear of his light twin and called Departure. With little traffic, he received clearance direct Sydney, his home town. Matt pointed the nose to the North-East, engaged the autopilot, and looked where he had put his newspaper.
Ten seconds later, he dropped the paper and stared at the GPS. What the hell was he doing? Sitting here in his own airplane, reading the newspaper, having himself transported home like cattle… why did he actually own an airplane and did not just book a seat on an airliner? The next morning, he sold off the aircraft, and decided that he would take ten years to build a credible, semi-professional simulator, to get the fun part of flying back into his life.
By the year 2000, the simulator actually was flyable and Matt decided to organise a small event to get some operation going. The aircraft simulated was a Boeing 747-400, so an around-the-world series of flights seemed the right way to go. A skeleton crew was assembled, and on November 5, 2000, Worldflight took to the skies, raising money for the Royal Flying Doctor’s Service.

Over the years, Worldflight has grown to an annual event with a large share of followers. By now, up to nine full-size flight decks join the group, augmented by dozens of desktop simulators flown by people all over the world. All aircraft are linked into a virtual airspace provided by one of the virtual ATC networks, VATSIM. They can see each other out of the window, register all on TCAS when so equipped, and create a buzz of traffic that is quite a handful for the controllers.

Near midair at Minneapolis-St. Paul airport (MSP)
On 24/09/2010, in Life around runways, by steve
On the morning of September 16, at around 06.49 a US Airways Airbus A320 (N122US) operating as flight AWE 1848 was cleared for take-off from Runway 30R bound for Philadelphia, Pennsylvania, with five crew and 90 passengers on board.
At the same time, Bemidji Aviation Services flight BMJ46, a Beech 99 cargo flight with only the pilot aboard, was cleared for takeoff on runway 30L en route to La Crosse, Wisconsin.
Weather conditions at the time were reported as a 900-foot ceiling and 10 miles visibility below the clouds.
Immediately after departure, the tower instructed the US Airways crew to turn left and head west, causing the flight to cross paths with the cargo aircraft approximately one-half mile past the end of runway 30L. Neither pilot saw the other aircraft because they were in the clouds, although the captain of the US Airways flight reported hearing the Beech 99 pass nearby. Estimates based on recorded radar data indicate that the two aircraft had 50 to 100 feet of vertical separation as they passed each other approximately 1500 feet above the ground.
The US Airways aircraft was equipped with a Traffic Alert and Collision Avoidance System (TCAS) that issued climb instructions to the crew to avert collision. The Beech 99 was not equipped with TCAS and the pilot was unaware of the proximity of the Airbus. There were no reports of damage or injuries as a result of the incident.
NTSB and FAA investigators conducted a preliminary investigation at the Minneapolis airport traffic control tower on September 18th and 19th and are continuing to review the circumstances of this incident.
Interesting people, unusual flight plans…

Mike Russo – Looking back on a lifetime in aviation
Mike, lead principal engineer and Executive Secretary of the AEEC has recently retired from Aeronautical Radio Incorporated (ARINC).
What were you dreaming of becoming when you were a kid?
I grew up in a rural family with limited means and there were not that many people around me who could have served as examples for choosing a profession. But I did want to find a respected profession, doing respected work. At one point I took an aptitude test and it showed that I would make a good mechanical engineer. My focus from then on was on science subjects. An uncle was a tool and die maker and I got a lot of support from him.
What moved you to become part of the aviation family?
I went to Lake Michigan Community College for an associates degree as a technician and then Michigan Technological University where I got my Bachelor’s Degree… Afterwards I got a job with Westinghouse and in 1971 they sent me to the FAA Academy to learn about the principles of ILS. On my return, I worked on various ILS projects including ground site design and field work for ILS installations including flight testing with the FAA.

KLM and Aeroflot take-off from taxi-ways
On 02/03/2010, in View from the left seat, by phil
Strange as it may seem one of the more difficult things that pilots have to deal with is finding their way around airports. Despite ICAO standardisation many obvious things like airport signage are not always the same at every airport, and even if they were, airport layouts will always differ. Surprisingly, navigating the aircraft down through the descent and arrival routes, then flying the approach and landing can often be easier than trying to navigate around the taxiways after vacating the runway. Equally, after all the hassle of getting the passengers on board, completing the checklists, pushing back on time, starting engines and leaving the ramp, finding ones’ way to the runway is not always as easy as it may seem. It really is extraordinary how difficult a seemingly simple task can be!
On the aircraft I used to fly, we had no map displays – only the basic fight instruments and paper charts. We followed our progress around the taxiways as carefully as we could following the charts. But even in good conditions it was surprisingly easy to become confused or to make a mistake. Usually this was resolved very quickly by reference to the marker boards and by checking compass headings, or by asking the tower for help. But sometimes one made a wrong turning, especially in poor visibility, or when everything was covered with snow, or at an unfamiliar airport.

Familiarization flight with Transavia
One of the countless drawbacks of 9/11, a few of you may have realized, is that even for air traffic controllers it has become increasingly difficult to visit a cockpit of an airliner, indeed most of the airlines adopted a closed cockpit door policy. I used to take every opportunity to at least say hello to the crew and was always happy to take the jumpseat for an interesting landing. But those times are over I’m afraid, probably forever and I don’t even ask the cabin crew anymore as I know the answer will be a polite: Sorry it’s not possible…
A happy crew
In the past Maastricht Upper Area Control Centre (MUAC) had agreements with various airlines which offered us ATCO-s the chance for fam. flights to see the place where all that actions happen. One of my most memorable experiences goes back to 1996 when I flew in the cockpit of a Swissair MD-11 between Zurich and Montreal Mirabel. So I was particularly happy when we learned about the great new initiative: Transavia Airlines (commercially rebranded as transavia.com after the basiqair period) was willing to renew the nice tradition of familiarization flights for air traffic controllers, offering us Maastricht controllers a quota of 50 flights a year.
Needless to say I was amongst the first ones to apply and received a confirmation email the previous day that I will fly on the 8th of March with TRA5143 from Amsterdam to Alicante and back on the same day.

What have we learnt from TCAS?
On 24/08/2009, in View from the left seat, by Alex1
If there’s one sure bet in this world it is that pilots and controllers will disagree about TCAS. Controllers believe it is an invention of the devil, pilots love it, if it is u/s, they feel naked. It is a remarkable technical achievement. I remember several UK CAA briefings in the very early 80s which declared flatly that an airborne collision avoidance system was just impossible, so it was something of a surprise to find working prototypes within a few years. The first versions were very limited in their ability to adjust the advisory, and would quickly announce ‘TCAS Invalid’ if the original RA no longer suited the situation.
Pilots vetoed that, and the first operational version was vastly more capable, with the ability to upgrade, downgrade, or even reverse the advisory. Later versions improved the coordination logic. The basic collision avoidance algorithm, however, is still recognisable, based on ‘tau’ (range/range rate) criteria.
Before TCAS entry, I took part in a number of controller briefing sessions. People came up with all sorts of ingenious scenarios that they were convinced TCAS could not handle. Almost without exception TCAS passed those tests. But there is a flaw in TCAS that those controllers, and to be honest most of us working closely on the project, either ignored or under appreciated. It is the boring old problem of the human in the loop.

Fly on the right – A mid air mitigation
On 03/08/2009, in View from the left seat, by Alex1
On 29 September 2006, A GOL B737-800 and a private Embraer Legacy business jet collided at FL360 some 200 miles north of Brasilia, over the Amazon Jungle. The Embraer’s left winglet hit the 737’s left wing, and the 737 crashed killing all on board. The Embraer was luckier, and made a successful emergency landing at the Cachimbo air base.
Both aircraft were equipped with transponders and TCAS, so how could it have happened? But the technicalities divert attention from a vastly more important point: Was it simply bad luck that the aircraft were so close together horizontally that they collided?
