And the first Alwyn Award should be awarded to Leady, who claims that the NAS 2b Class E airspace was a success:
Follow that by the same organization's analysis for the NAS 2b windback. In my opinion and many others the "risk assessment" was a disgrace, (after 12 months of successful operation)
3 RAs involving RPT IFRs and no-radio VFRs = success.
Those three incidents were correctly read by AsA as ringing alarm bells about the fundamental flaws of E airspace.
the UIRs, FL250 to FL600 were only "advisory airspace" --- close to F, as India used to operate F.
Is that so? I didn't know QF still operated 707s in 1990, when ICAO created Alphabet airspace. Advisory airspace it may have been. It certainly wasn't F.
I ask yet again: what is the benefit of E airspace?
Dick,
what about C without radar- how do you get a positive ident!
What about it? Who needs a positive ident? Break free of your fundamentalist views and do some lateral thinking: aircraft control can be done without surveillance!
