Certainly helps Eck,
I completely agree with the fact that an ILS should be flown at uncorrected heights once established.But would'nt u need to apply a correction to the other platform heights like say the Faf holding altitude.And should'nt Atc be aware of this corrected altitude since everyone would be 'correcting'.
In the Rnav approach I am quite sure that u need to use the 'corrected' altitudes in order to be able to use the Vnav function of the approach.Once again....wondering why Atc should not be aware of the correction.Most Rnav precision approach charts clearly depict the temperature at which they were 'caliberated'.Which is also the minimum temp at which an uncorrected Lnav/Vnav approach can be flown.Below this temperature(OAT),a temperature correction MUST be applied to ALL approach altitudes in order to satisfy obstacle clearance requirments and meet legal requirments for a coupled Lnav/Vnav approach.As you so corrrectly pointed out.However,still wondering if one would need to apply the same corrections for the same conditions for a more conventional precision approach.....say a ILS.And once again would one need to inform Atc....
Thanks again
