You may have a point, but have a look at the PFAs response to the Coventry proposals.
They make a reasoned case for reducing the proposed CAS around Coventry as being disproportionate. It is a many times larger area per movement than any of the London Airports for around 5 movements a day.
It appears that the airport want to accommodate the low-cost airlines which, to save fuel, chose not to use the existing CAS but take a short-cut through Class G.
Thee are similar proposals at other expanding regional airfields but all need to be viewed critically, and reduced to a reasonable extent.
What we don't want though is the case of a mid-air collision when a commercial jet decides to take a shortcut, thinking they have automatic right of way.
By the way, are airline pilots taught to look out? 70 hours actual flight time seems incredibly low and I would question the real-world airmanship of a pilot with that level of experience in the air
