I received a terrain warning alert and low altitude alert notification from Fairbanks Approach [while on the] GPS 20L Approach into Fairbanks International. At the time; corrections were already being made.I was undergoing a route check with a company check airman; and the check airman was attempting to be helpful; but there was a communications breakdown between the pilots resulting in confusion [as to the minimum] altitude of that approach segment.Better communications and understanding between the airmen would have helped prevent this problem.
A C-208 pilot being given a route check by a check airman received GPWS Terrain warning and an ATC issued Low Altitude Alert while conducting an RNAV (GPS) Runway 20L approach to FAI. A communications breakdown between the reporter and the Check Airman was cited as a contributing factor.
