I've just noticed in the latest CAP (Canadian approach plates) that the MDA
for the LOC(BC) 25 approach at Ottawa/CYOW has been lowered from 800 ft (427
AGL) to 660 ft (287 AGL). I can see how it makes operational sense -- it is
the approach runway usually named in the ATIS (despite the fact that two
others have ILS's) -- but an MDA of 287 ft AGL seems low for a non-precision
approach. Are there many similar examples out there?


All the best,


David
