NAS rears its head again

[Howabout]

Hi Dick, I refer you to my previous post. Based on your argument, deductive logic states the following, if we extend your hypothesis.

• Class C over Class D is 'upside down airspace,' and counter to sound airspace management and scientific principles.
• If the 'threat level' in overlying terminal airspace is less, it should be a lower classification than that in the vicinity of the runway (correct so far??).
• Hence Class A airspace over Class E, which is across the continent, is also 'upside down' and must also be counter to sound airspace management and scientific principles.
• Clearly, if the risk is less in the 'outer terminal area,' then the risk must be so much more reduced in an enroute cruise environment.
• So, your argument, taken to it's most obvious conclusion, is that enroute Class E, which extends up to F245 so someone can fly a jet VFR up there where RPTs operate, should have an overlying airspace construct of a lower category - otherwise it's 'upside down.'
• Ergo, airspace above F245 should be either F or G, otherwise it's 'upside down'.

Discuss.
