Quick question probably more for the IR instructors/ATC. Was always under the impression that if one had commenced an approach (when weather was above minima) and the weather then dropped below minima, one could continue the approach down to DA. Incident several days ago when this happened to me. ATC passed an RVR which was below minima. I replied "roger". They then asked me to confirm i wouldnt be descending below 1000ft aal (which I already was). Only option was to abandon approach and go around. Im not disputing ATC were wrong but have things changed recently or have i misunderstood regulations. If anyone has comments or can direct me to a definitive answer that would be gr8.
Thanx All
