if it seemed that he had looked at the plates for Biggin and knew there was only one precision approach, or if he had read up on the services he might get OCAS
Maybe my point was not well made:
I looked at the approach plates for Biggin Hill and by those I believed (correctly) that there was only an ILS approach to RY21. Once I picked up the ATIS which stated 600 foot ceilings and RY03 in use I began to second-guess myself. Maybe I overlooked something?
I can only speak for myself but with 600 ft ceilings and light (9kt) winds I find it unusual that they would state the runway in use was one without instrument approaches.
