I cannot currently find an ICAO or CAA definition for SRA but they are assigned Absolute Minima implying an Instrument approach. The SRA terminating at 2 nm falls within VMC minima therefore I see no reason for VFR flights not to undertake SRAs for visual acquisition. The SRA is a Non-Precision aid so presumably compatible with limited instrument flight capability. Flying an SRA nevertheless requires a lot of instrument attention therefore the VFR pilot should take a competent look-out observer. Step-down fixes may preclude VFR flight. If the pilot chooses not to fly the GP then he will need to inform the controller who may be tilting the SRE aerial elsewhere and may easily lose the target. If VFR pilots are avoiding IMC on the approach then the pilot must inform the controller that he is unable to comply with the heading instruction. This may result in an unstable approach where the aircraft is poorly placed for a landing. For controller training I prefer the pilot to be IMC capable in order to achieve a stable approach without interruption. We are, after all, training for SRAs in IMC in order to achieve successful visual acquisition at minima, so I think VFR SRAs have limited mutual benefit.
