I would say Pilot aptitude (3/4-D awareness, high workload capacity) reads across quite well on the aptitude front. After all, I passed both Pilot and ATC Aptitude testing in my early days (OASC x 4, on various attempts to get though the door!!).
And a late good mate, albeit ‘wingless’, was ‘failed aircrew’ which might have explained his bolshie-ness ... or just being Welsh
He still made wg cdr, though!
Fellow RAF ATCOs will know who I mean ... and I was one of a few who could call him Blodwyn without being prostrated on the floor!
