SM... I am rather amused that you think the new NPAS will have such authority! While much better alignment and coordination between the various services you mention is on the cards over the next few years.. I don't think the NPAS is in a position to direct such events. RUSI is publishing it's report next week on it's UK "blue light" aviation studies... So worth a read by all interested parties and individuals. Its not government policy yet, of course, but I think it's going to have some influence on it in due course.
