Hi Bob/Richard,
Just referring to your book on page 3.5, the example of an aeroplane with one ADF and TSO129a GPS, planning a charter flight to an aerodrome that has an NDB approach along with an RNAV and GPS arrival procedure, the flight would require an alternate since you cannot use a GPS dependent procedure for planning purposes. However, wouldn't the alternate also require an alternate, as your aircraft still does not have the 2 required aids under Charter operations.

That is correct. You cannot use a 129 GPS to satisfy the alternate requirements. For a charter flight you would have to have an alternate that would permit the use of LSALT + 500 and 8 km vis on the ARFOR. This is another example of how badly worded the AIP is. You would have to have an alternate that is not served by a navigation aid. AIP ENR 1.1 para 58.3.2 says that LSALT + 500 and 8 km vis is available only if the aerodrome 'IS NOT SERVED BY A NAVIGATION AID'. That means even on a day without a cloud in the sky, an aerodrome with an NDB approach would not be suitable as an alternate - you would have to look around for an aerodrome that 'IS NOT SERVED BY A NAVIGATION AID'. Don't think about it to much or you'll become just as cynical as I. Maybe you should all write to CASA about this crazy wording - I've already done that.
