To fly instruments within US controlled airspace you must have approved equipment, a weather briefing, meet minimum approach weather requirements, IFR fuel reserves, current publications and a current and approved pilot.
This Apache was equipped with two Inertial Navigation Units (Embedded GPS, strap down ring laser gyro, doppler. and a highly integrated air data system). It is equipped with a moving map display with stick, chart, dig map, and satellite displays (1:50, 1:100, 1:250, 1:500, 1:1000). In addition it has individual pilot and CPG FLIR. No autopilot but both attitude and altitude hold (with hover capability).
Although capable of flying point to point in instrument conditions, the Apache is not considered qualified for flight in the civil airspace system (except in an emergency) nor is it qualified for a zero/zero approach.
I concur with this pilots decision to land. I believe that this pilot has 80 hours in the Apache, not 80 hours total time.
