There is a misconception in some air traffic management circles that trajectory based operations is simply business as usual except that the current, notoriously imprecise ground generated trajectories are replaced by more accurate, 4 D trajectories and that is all there is to it. Some will add that parts of this 4D trajectory might be… Continue reading Do you really understand – Trajectory based operations (TBO)?

Trajectory based operations (TBO) – Still not properly understood in SESAR? Take 2.
You may recall that a while ago I had written an article with the same title, expressing concern that this all important element in the SESAR Concept of Operations was apparently still not properly understood by some of the “experts” working on the subject. Recently another paper dealing with trajectory management crossed my desk and… Continue reading Trajectory based operations (TBO) – Still not properly understood in SESAR? Take 2.
Trajectory based operations (TBO) – still not properly understood in SESAR?
Following Henning’s article about the fate of the original SESAR Concept of Operations (CONOPS), I received a slew of mails basically confirming his point of view and worries. Of particular concern seems to have been a document dealing with trajectory management… People who had seen this document were of the opinion that it was little… Continue reading Trajectory based operations (TBO) – still not properly understood in SESAR?
Are ATM operational concepts the cause of failure?
I have known Jean-Marc Garot, the former director of EUROCONTROL’s Experimental Centre in Paris for a long time. A forward thinker and in many ways a visionary, he retired from EUROCONTROL in 2005. He has now published an interesting article in The Controller magazine with the title “What is an ATM concept?” I think everyone… Continue reading Are ATM operational concepts the cause of failure?
Continuous Descent Operations (CDO) Manual from ICAO now available
ICAO has made available an unedited, advance version of the Continuous Descent Operations (CDO) Manual as approved, in principle, by the Secretary General. Although the final, edited version may still undergo editorial alterations, the substance should stay the same. The purpose of this Manual is to provide guidance and harmonize the development and implementation of… Continue reading Continuous Descent Operations (CDO) Manual from ICAO now available
U.K. airspace "developments"?
A short article in Aviation Week and Space Technology caught my eye the other day. “Restructuring U.K. Skies” was the title and it announced that the U.K.’s Civil Aviation Authority (CAA) was beginning the process of defining airspace out to 2030, with industry-wide dialogue to begin in 2010. I counted the number of times the… Continue reading U.K. airspace "developments"?
Trajectory Based Operations (TBO) – what is this?
We have all grown up with the idea that airspace was the most important single thing aircraft needed. While it is true that aircraft need both air (in which the wings can generate lift) and space (the room to move around in) but airspace? This word has grown over the years and held us hostage… Continue reading Trajectory Based Operations (TBO) – what is this?
Military accepts the idea underlying the business trajectory
One of the most important paradigm shifts in the SESAR air traffic management operational concept of the future is the move from an airspace based approach to a trajectory based one. It would be a bit lengthy to explain the difference here (there will be a blog article on the subject soon) so let it… Continue reading Military accepts the idea underlying the business trajectory
New directions for Airport Collaborative Decision Making (CDM)
What exactly is CDM? Collaborative Decision Making (CDM) is not a new concept. It is being practiced to a certain degree both in the US and in Europe, focus being on en-route in the former and airports in the latter. Mature as the concept may be, surprisingly we still see experts who seem to believe… Continue reading New directions for Airport Collaborative Decision Making (CDM)
(Before) all else fails… read the Concept! Part 3.
What is TMR? The abbreviation of Trajectory Management Requirements and an item that has been misunderstood in several ways (some quite surprising). Obviously, the CONOPS did not do a very good job of explaining this simplest of elements (mea culpa…). An aircraft flying its 4 dimensional trajectory will do so with an agreed precision and… Continue reading (Before) all else fails… read the Concept! Part 3.
