No Change There
Hi Jydo, I helped to set up Express Airways Nigeria (Kaduna) Ltd., The guys in the Control Towers were (generally) helpful. They knew that without airlines operating, their jobs weren't required. As pilots, we found it useful to chat, when we were on the ground, to establish a personal relationship (or, at least, I did). I wish you all the best in your career. Keep it clear. Keep it short and keep it slow. Saves all that "Please say again" stuff. Cheers.
