Question 3

What are the limitations regarding temperature and FINAL APP mode?

A GNSS approach can be flown in final all as long as the temperature is above the stated limit.

If temp is below the limit approach can be flown in Nav mode with selected vertical guidance and the LNAV minima

Question 4

Why can FINAL APP not be used if a temperature correction has been applied?

Answer 4

Because we cannot modify any part of the final approach in the FMGC, so there is no way to apply temperature corrections.
