Narrative:

Upon entering the bogota terminal area, approach control cleared us to the VOR which begins the ILS approach (if). The GPS was programmed to the IAF-if-ILS. The first officer typed in 'bog' rather than selecting from the flight list on the GPS. He failed to catch dual bog identifiers. The aircraft turned to the general direction of bog VOR however, approach controller caught error and gave an immediate heading and altitude to the bog VOR, and a subsequent clearance for the ILS. Contributing factors: thunderstorm, turbulence, change of clearance and unfamiliarity with new GPS system onboard. The GPS works well when inputs are verified but when in a rush, mistakes are easily made. All actions need to be verified and backed up with outside navigation facilities when available. Company policy is to use the GPS in the terminal area, however in hindsight until we, as a crew, become more familiar with the system I believe raw data should be used in the terminal area for primary navigation.

Title: A B727 FREIGHTER CREW MISUSES THEIR NEW GPS NAV SYS AND GETS A 'SAVE' FROM BOG APCH CTLR WITH A NEW HDG AND ALT.

Narrative: UPON ENTERING THE BOGOTA TERMINAL AREA, APCH CTL CLRED US TO THE VOR WHICH BEGINS THE ILS APCH (IF). THE GPS WAS PROGRAMMED TO THE IAF-IF-ILS. THE FO TYPED IN 'BOG' RATHER THAN SELECTING FROM THE FLT LIST ON THE GPS. HE FAILED TO CATCH DUAL BOG IDENTIFIERS. THE ACFT TURNED TO THE GENERAL DIRECTION OF BOG VOR HOWEVER, APCH CTLR CAUGHT ERROR AND GAVE AN IMMEDIATE HEADING AND ALT TO THE BOG VOR, AND A SUBSEQUENT CLRNC FOR THE ILS. CONTRIBUTING FACTORS: TSTM, TURB, CHANGE OF CLRNC AND UNFAMILIARITY WITH NEW GPS SYS ONBOARD. THE GPS WORKS WELL WHEN INPUTS ARE VERIFIED BUT WHEN IN A RUSH, MISTAKES ARE EASILY MADE. ALL ACTIONS NEED TO BE VERIFIED AND BACKED UP WITH OUTSIDE NAV FACILITIES WHEN AVAILABLE. COMPANY POLICY IS TO USE THE GPS IN THE TERMINAL AREA, HOWEVER IN HINDSIGHT UNTIL WE, AS A CREW, BECOME MORE FAMILIAR WITH THE SYS I BELIEVE RAW DATA SHOULD BE USED IN THE TERMINAL AREA FOR PRIMARY NAV.
