Well done on trying to do something about this.
1st time round, we could fly down Glasgow's runway no problem.
2nd time round, Glasgow closed their airspace (airfield was also closed for maintenance).
Had the crazy situation that a controller at Glsgow would tell you over the radio that ATC was closed, so wouldn't even offer a Basic ATSOCAS service. So couldn't keep one updated about the ash!
3rd time around (today) the Notam states:
THE AREA IS DESIGNATED A NO FLY ZONE (NFZ)(ICAO DEFINTION: AREAS OF
HIGH CONTAMINATION) SINCE THE CONCENTRATION OF ASH MAY EXCEED TEN
TIMES THE STANDARD THRESHOLD AND THEREFORE MAY EXCEED SAFE LIMITS. NO
CLEARANCES WILL BE ISSUED TO PENETRATE THE NFZ.
So, again, Class D airspace is closed to all traffic, including VFR SEP and microlights.
Why?
If we can operate outside controlled airspace, and there is no traffic in the Class D to "control", why not make the Class D Class G?
