Headquartered in Brussels, Belgium, EUROCONTROL works closely with the European Civil Aviation Conference (ECAC) and the European Union (EU). Indeed, EUROCONTROL, the EU and the EU member states signed a protocol in 2002, enabling the EU to accede to the Revised EUROCONTROL Convention.
Thirty-seven countries are members of EUROCONTROL. Of these, twenty-five are in ECAC, EUROCONTROL and the EU and twelve are in ECAC and EUROCONTROL, but not the EU. Two countries are in the ECAC and EU, but are not members of EUROCONTROL. A full membership list, together with "dates of adhesion" and graphic maps may be found on the membership page of the EUROCONTROL web site. It is both a civil and a military organisation and its primary objective is the "development of a seamless, pan-European Air Traffic Management (ATM) system.
On the EUROCONTROL web site page on membership here in a section headed "The ECAC Member States", is an explanation of the working relationship and a small graphic, which *looks* as if it could be a close up photograph of the ECAC flag. I've not researched this further, as I can't find anything on the ECAC web site or elsewhere to indicate that they have a flag or to confirm the status of this image.
Thus, I'm just sending this report to the list in case anyone else might perhaps be an aviation enthusiast or otherwise knows about any possible flag of this organisation.
French and English are its working languages, which is why I've put the title in both languages in the subject line.
There is an image of the EUROCONTROL flag, cropped from a photograph on their web site. Here is some text, to accompany the image:
"The EUROCONTROL flag, as flown outside its Brussels headquarters, is simply the organisation's logo, on a white background. This consists of a rounded, stylised lower case letter 'e' in dark blue. Superimposed upon the letter 'e' and obscuring part of it, is a stylised image of an aircraft tail fin in a lighter shade of blue. It is not presently clear whether the organisation's abbreviated name also appears on the flag, although the word 'EUROCONTROL' does appear immediately underneath the logo in block letters and a different shade of blue on other documents and publications of the organisation, including its web site, which is the primary source for this report."
While doing a little research tonight, I came across a photograph of the EUROCONTROL flag. Not being familiar with that organization, I immediately hit up FOTW, only to find no entries for it. Coming to the Yahoo Groups archive, I found that the organization was ever-so-briefly discussed in February 2007, at which time the group consensus was that the flag consisted of the organization's two-toned blue logo on a white field without the lettering denoting the organization's name or acronym.
Based, however, on the photograph I found online tonight, the flag does appear to include the name "EUROCONTROL" in blue capital letters beneath the logo.
There is another photo in the PDF as well, showing all the member-state flags plus the EUROCONTROL one. It appears to be without lettering.
Trusting the photo flag seen very small among member's flags on line, the specs are (11+34+11):(22+40+22) = 2:3. I used the vectorial image (with a bit of recolouring)
All photos of this flag (granted that not many) seem to show the logo centered and the lettering absent. For now, I'm betting on no letters.
