i recently went for an interview where i was asked a question:
what is the RNP value required for an ILS, VOR and a NDB approach?
i fly the airbus A-320 and this question confused me a bit and i stated that there is no relation between RNP and an ILS approach.
however, i was told that this is not the case and apparently there are RNP values of .3, .5 and .6 for the approaches respectively. i have not been able to find these values in any airbus specific or general literature on RNP.
However, on consultation with a few friends flying the Boeing 777, i found that these values are mentioned in their SOP. (the person asking the questions was a 777 Examiner).
can someone please clarify with source. the interview was a navigation interview for ATPL and feel it was not fair to be asked a 777 specific question. (my friends on the 737 say there is no such thing in their SOP).
however i wouldnt mind being contradicted.
thank you.
