When an Authority can say one check ride every six months and you are both current and proficient in IFR/IMC flight....being a bit anti-authority might just save your life.
Just because the Authority says you can....doesn't mean you must or should.
Crab,
With the advent of GPS, FMS systems, Autopilots with four axis capability, RadAlts, TAWS, GPWS.....and FLIR....can you with your SAR experience....envision an IAP for that landing site that if properly surveyed, flight checked, and re-surveyed monthly for changes in the way of obstructions to include checking with the local authority to see if there. have been any Building Permits filed for or approved within the surveyed flight path?
What Minimums would you think workable and safe?
The Operator/Client had gone to the lengths to provide a visual glide slope and landing azimuth device....which shows their intent was to find ways to make their operation safer by seeking some usable technical assistance.
Would not that Point in Space IAP be one such thing that would have worked for them had they had that option?
