Try 2550' (or 2750') to taste, and 6300'? (or 4100', or....). Nice and easy, isn't...

Interesting, when important elevations are not agreed. All other things being equal, if Mr X impacts 50' below the top of a 2750' spot height charted at 2550', is the chart provider liable?

No, the inner TAA area is 4 n.m. in the straight-in TAA area (the north side). - so if I have this right, on these 'new' RNAV charts, the min hold alt will always be the lowest of the TAA values? NB...

ATC Watcher - nothing 'crazy' there - why not ask why someone built a 2550' hill near the approach to R19? With the MSAs around there, a 13 mile IAF is about right - could not be closer. In any case,...

I am not aware of the different levels of ATC service in those parts, but have we established what they were on, or perhaps thought they were on?
