    Yes.  However, it may not be used to provide navigation on the final approach segment of an approach in place of an ADF, so you can’t use it to perform an NDB approach on the final approach segment unless the title includes “or GPS”.

    Thank you very much John, How about the Distance? Can we use GNS430W legally in place of DME?

    Ami,
     
    Yes, an IFR GPS such as the GNS430W is considered a suitable RNAV system. In the AIM, read and study section “1−2−3. Use of Suitable Area Navigation (RNAV) Systems on Conventional Procedures and Routes”.  It is about two pages long and tells all the details as to what you are permitted to use your GPS for.  After you read it, if you still have questions, post a new question.
