The IAA is not a company like Tesco or BT. Corporate sponsorship is commonly used to increase a company's profile or simply to place it in the public view so that people will buy it's products or use it's services.
The IAA's job is as per it's mission statement to wit:
The Board and Staff of the Irish Aviation Authority are committed to providing efficient and cost-effective safety regulation of the Irish aviation industry and to providing, on a sound commercial basis, safe, efficient and cost-effective air navigation services, which meet the needs of our customers.
The Authority aims to be a world leader in its field.
No more, no bloody less. It is bang out of order to be sponsoring anything outside it's remit.
I have more than a suspicion that this sponsorship deal is as a result of some high up nob in the IAA having a son or daughter involved in the music scene.
This sponsorship does nothing to increase aviation safety or air navigation services.
I for one will be making a complaint to whichever minister is in charge of aviation.
