I'd like to start up a discussion on unpublished or 'home-grown' instrument let-downs.
Many of uf with IR or IR(R) find ourselves at local airfields with no published procedures. Arriving VMC on top with 8/8 below, a diversion to the nearest published procedure is obviously the 'correct' exam answer; but real-world, many of us will letdown to MSA on a VOR radial or GPS position (RAIM checked
).
The recent fatality in Oxofdshire thread raises doubt as to the long term safety of this practice (it's mentioned in one of the threads). Can I question this? If accurately flown, with stations tuned, identified and 'flags away' and or GPS RAIM checked, what do we think are the risks?
Collision with other acft is a given. Would a traffic service be mitigate risk sufficiently? What does everyone think?
