  • What is the greatest distance from Alpha to Bravo that would permit this flight to be planned?

    You are planning an IFR flight from Alpha to Bravo. Alpha and Bravo each have an NDB with co-located DME. The aircraft you are flying has 1 x GNSS, 2 x ADF, 1 x DME. Your GNSS is unserviceable. The rated coverage of the NDB at Bravo is 45 nm and the rated coverage at Alpha is 60 nm. You intend to cruise at 8000 feet and there is a 20 knot tailwind component along the flight planned track.

     

    What is the greatest distance from Alpha to Bravo that would permit this flight to be planned?

     

    If anyone can answer this would be appreciated.
