Ah Spitoon, you absolute hero. That Article 103 was exactly what I've been looking for, for the past x number of weeks.
The reason I was asking is that I work at a FIS unit airfield, the management of which is adament that they will introduce a non-precision GPS approach much the same as Shoreham.
Of course, at first glance to me it seemed ridiculous that you could have any kind of approach procedure at an airfield without a control service - not too long ago I witnessed a Bulldog completely cut up a BAe 146 by turning final way too early, which resulted in the 146 having to go around. Having this happen during the final stages of the approach procedure would only end in tears.
Non-precision GPS approach....at your discretion....no known traffic to effect...
