Hi Dick, its Frog Fan but nevermind
I get your point about wet grass except in this case it was concrete. The dew point was noted later by referring to a METAR issued at 6 am, an hour before sun rise so had to be a degree or two lower by then.
I don't recall that the gauge was touching the yellow line either but concede it must have been fairly close.
What do you think about Robinson removing all reference to the gauge from SN-25?
Surely it implies that the gauge is not to be trusted. Where in the POH is there anything about testing the gauge also?
It kind of looks like Robinson knows that the gauge is inaccurate, suspect that it may have caused accidents (the evidence after all disappears in seconds) and are covering their ass with the amended notice so their lawyers can point and say 'we warned you, so no our fault'.
