Probably the CTAF if there is one and you are in the vicinity of an
aerodrome, otherwise the multicom(126.7) under the same circumstances. If
it is a gliding field it might be a good idea for the club to use the
multicom in the circuit area instead of 122.7 or the other gliding
frequencies or standardise on 122.7 and not .5 or .9 in the circuit area
then if you see a gliding symbol on the map you can use 122.7.
There is nothing optional about the CTAF monitoring if you are using that
aerodrome and have a radio. The indefinite size isn't a problem either it
gives you the option of delaying your call until closer in if you are
flying a Storch at 60knots or making it further out if in a 200+ knot
aircraft. In both cases the call might be more useful. In any case at least
it is less likely that two head on aircraft both have pilots going head
down to change frequency in exactly the same place.
The so called professional IFR pilots seem to think that IFR was invented
so they didn't have to look out. They do in VMC. IFR was invented to let
them fly in cloud.
