Chimbu,
Sorry about not being quite clear enough.
If a C145/146 GPS engine is at least Gamma3, it can handle LPV, but WAAS is a must. No WAAS, and the LPV function is inactive.
Thus, do you believe it is appropriate (honest?) to include LPV benefits in the JCP C/B "study".
So, keep those letters flowing in to your local member, even if AsA and its major bill payers prefer GRAS (for some very good reason --- and they don't benefit from WAAS) there is the little matter of the rest of Australia, not just the Regionals down, but all forms of transport, marine, mining, survey, agriculture etc. WAAS up, Doc.
Another example of the national interest not being the same as the commercial interests of AsA, but reading the ADS-B or bust brigade comments, one might believe so ---- that we, the bulk of the aircraft on the VH- register, should be forced to have a system we don't need, to solve a problem we don't have, because AsA says it will save somewhere between 2-4% on the bottom line.
At a cost to us of some AUD$200M plus over the program period.
Everybody who has been critical of Dr.R.J.Hall's paper dissecting the JCP have been very strong on assertions that he is wrong, but there is not one word to support the assertions.
Tootle pip!!
