People,
Much emotion on the E and C airspace, understandably but has anyone got an answer for this scenario:
IFR aircraft at say, 7000 feet an a mandated QNH from ATS.
VFR aircraft at say 6,500 on which QNH........Area; Departure airfield; one from a TAF withing 100 nms; AERIS; Metar; Destinaton etc..
I have seen signficant differences in all these QNH sources and while the IFR aircraft is provided with one requiring clear compliance, the VFR one can, at will, set any of the above.
Add some turbulence or even some pilot inaccuracy in height/altitude holding and the height/altitude separation can be considerably reduced.
But perhaps the Safety and Risk Managment people have done the sums and I suppose it must be safe?
Just thought I would ask
