Block Levels
LurkR,
You should find that this has no impact on skywriters:
- Skywriting abouve major capital cities would be in Class C airspace, block levels are allowed
- Block levels not allowed to be assigned in E airspace to IFR (including military at the moment) becuase of the chance they could clean up a VFR, and E airpace is heavily dependent on all aircraft cruising at the hemispherical levles outlined in AIP. If you are a skywriter and operate in E airspace, you would be VFR and not require a clearance ... and as for operating at block levels (since you don't need the clearance), check AIP, but I am guessing "operationally required" would fall under that category? However, if you were a skywriter and operating in E airspace and operating at different levels, making yoursepf known to ATC might not be such a bad thing if there is IFR traffic opertaing in the area (although I am not suggesting this as the books don't say to do this and after all VFR is see and avoid in the new system).
