When they discovered a heart problem that had been present since birth (and for the duration of my 17 years flying to that point), they made me "2-pilot only". RAF sent me private and fixed it PDQ. Mind you, took a year to get a RAF medical board convened afterwards to confirm my "single-pilot" status. Ask the medics to send you private and queue jump. You're a valuable commodity being wasted while you wait for the NHS.
