A RPTR SUBMITS A SUGGESTION TO ENHANCE THE ACCURACY AND USE OF TIMING TO THE MISSED APCH POINT (NON PRECISION APCHS) BY PUBLISHING SUPPLEMENTAL GLOBAL POSITIONING SYS WAYPOINT IDENT THAT CAN BE USED IN CONJUNCTION WITH THE TIME.

Narrative

WITH MORE AND MORE ACFT HAVING GPS ONBOARD; ALL APCHS (INST) SHOULD HAVE THE MISSED APCH POINT IDENTED BY LATITUDE AND LONGITUDE COORDINATES. USING GPS COORDINATES FOR THE MISSED APCH POINT IS A GREAT DEAL MORE ACCURATE THAN RELYING ON TIME; WHEN EXECUTING A NON PRECISION APCH. GPS AT THE MOST IS OFF A FEW 100 FT. BY IDENTING THE MISSED APCH POINT USING GPS COORDINATES SAFETY WILL BE INCREASED A GREAT DEAL WHEN FLYING INST APCHS BECAUSE THERE WILL BE NO QUESTION ABOUT WHEN TO EXECUTE THE MISSED APCH. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR FLIES AN SK76. BEFORE A GPS APCH WAS APPROVED AT AN ARPT THAT THIS RPTR COMMONLY UTILIZES; HE WAS ENTIRELY RELIANT UPON THE USE OF TIME TO IDENT THE MISSED APCH POINT WHILE FLYING THE NDB APCH. THE INTRODUCTION OF THE GPS STAND ALONE APCH GAVE THIS PLT THE ASSURANCE OF GREATER ACCURACY IN LOW WX CONDITIONS AND THIS EXPERIENCE IN TURN PROVIDED THE IMPETUS TO FILE THIS IDEA OF USING GPS IN ADDITION TO TIME; TO IDENT THE MISSED APCH POINT.
