As Fuji stated the pilot who landed on the 100 metres sticking out of the fog could have argued the fact that he landed in VFR and then used the takeoff /taxi minima for the roll out. He could have questioned the RVR equiptment as the readings were obviosly not correct on the touchdown.
I believe he was advised to admit guilt and took the £2000 fine
Correction to my statement above
he could not have avoided the prosecution because he accepted an approach and Ils when the RVR was quoted at below minima. That acceptance itself was an infringement.
Had he cancelled IFR and requested to proceed VFR to the runway for a look that may have been a way out?
