CAT 1 only ILS at SVO in January RVR 800m Overcast at 60M. Helped us get in safely using monitored approach.
If none of you, who operate in the 'Non-BA Sphere', have ever looked up at '50 above' DH and not seen a sausage, looked back in ...errr.. it's now DH...look out...err ....LAND. Then you have to admit that on that occasion you probably operated the aircraft outside its limits.
BA SOP's rid the crew of that grey area and consequently can only promote a safer environment at that critical stage during the final approach.
At all other times it can seem unnecessary, but had we not had that SOP at SVO earlier this year we would have had an unscheduled nightstop in HEL.
