Ken,
The point is that some of those crap staff jobs need an aircrew mate to fill them; because they need specialist knowledge. That's what marks them as "flying related," even if they're at HQ Air or Abbey Wood or somewhere miles away from the nearest runway.
They do attract flying pay though; it's a "non-flying related" ground job that puts you on the 2 year counter to reserve band. Hence why there aren't many of us volunteering to be IOT flt cdrs, or work in recruiting offices....!
