There was a time, up until NR became DFO that the CAD had a rule that all senior management roles were held by a pilot. The company asked the CAD kindly to amend that rule, and the proviso then was that the DFO could only be a non-pilot if all other senior post holders were pilots.... NR had to also spend some time learning the ropes as GMA before his promotion to DFO.
We now have 2 non pilot senior management post holders - at the same time!... Did the company even bother with asking CAD?
By doing it, it allows the accountants and "the board" to enforce (envisioned savings by cutting costs) "productivity gains" by being cheap. As there are less roadblocks in senior management to stop it on the basis of safety and experience.
I call this the "The Cheapness Paradox"... An almost exponential graph of cost cutting versus safety and quality...
The more accountants try and cut costs, the cheaper the product becomes, the shoddier all facets of the operation become, aeroplanes fall apart, pilots fall apart, the product falls apart - and in the long run, it costs them more money than what they saved by being cheap.
