What about flying an Australian registered aircraft overseas where no alternate minima is published on the plates?
Then you use whatever is published in their equivalent of the Australian AiP,
Eg. USA, FAR 91.169 c 1 (i) for other than helis, either specified on the plate, or for precision, 600' 2 SM, non-precision, 800' 2 SM.
ps. S
LAM??? Where'd that come from?
And slight correction to
i.e. they have two ILS / VOR receivers installed and serviceable.
The full Special Alt Min req. are;
Special alternate weather minima are available for specified approaches at some aerodromes for use by aircraft with dual ILS/ VOR approach capability; ie, with duplicated LOC, G/P, marker and VOR receivers. The requirement for duplicated marker receivers may be satisfied by one marker receiver and DME. (The assumption is that such aircraft will also have two ADF systems, when an NDB is used for the ILS).
The ILS is not a single stand alone instrument, it is a system. No such animal as an "ILS receiver".
