RRR
Thanks for the article. No mention of NDB approaches in my quick glance.
If an NDB approach is line selectable from the FMC then RNAV is to be used with full automatics to be used, as Capt. Claret has mentioned.
This goes for any VOR approach as well.
Centaurus
(Great sounding motor by the way) We are not talking about initial IR ratings. This is in the field regulated and company requirements being met.
BOAC
More like watching TV on your iPhone. Tolerance monitoring is ideal, l agree.
But if there are no ADF's installed, how are you to do that?
The best offer is RNP, which is a minimum requirement on an RNP RNAV approach anyway.
As long as the approach is validated for dist/TRK/GPA and minimum crossing altitudes (plus temp if required) and the minimum RNP is available, then why not?
