Narrative:

My routing from rome; GA; to atlantic city; nj; was amended en route. I was given the routing correctly by ATC and I copied it down correctly. However; when programming the GPS; I left out a waypoint. V229 has a dogleg and when programming the GPS; I omitted the intersection (gared; I think) that is the apex of the dogleg. So; when departing pxt VOR; I was on a more easterly heading than I should have been and came close to the pxt restr area and perhaps entered it. ATC called me with a vector back to the north which returned me to V229. This problem was caused by incorrect reading of the sectional chart which led me to assume that V229 was straight and caused me to omit gared intersection where it doglegs. Communication with ATC was not a factor. Callback conversation with reporter revealed the following information: reporter stated that this incident was totally pilot error. The GPS system does not list airways and; therefore; the operator must enter each NAVAID identify and then the waypoint between navaids if its track is not a straight line.

Original NASA ASRS Text

Title: AN M20 PLT USING A KLN 9B GPS NAV SYS FAILED TO ENTER A VICTOR AIRWAYS WAYPOINT AND MISSED A DOGLEG. HE APCHED A PXT RESTR AREA.

Narrative: MY ROUTING FROM ROME; GA; TO ATLANTIC CITY; NJ; WAS AMENDED ENRTE. I WAS GIVEN THE ROUTING CORRECTLY BY ATC AND I COPIED IT DOWN CORRECTLY. HOWEVER; WHEN PROGRAMMING THE GPS; I LEFT OUT A WAYPOINT. V229 HAS A DOGLEG AND WHEN PROGRAMMING THE GPS; I OMITTED THE INTXN (GARED; I THINK) THAT IS THE APEX OF THE DOGLEG. SO; WHEN DEPARTING PXT VOR; I WAS ON A MORE EASTERLY HDG THAN I SHOULD HAVE BEEN AND CAME CLOSE TO THE PXT RESTR AREA AND PERHAPS ENTERED IT. ATC CALLED ME WITH A VECTOR BACK TO THE N WHICH RETURNED ME TO V229. THIS PROB WAS CAUSED BY INCORRECT READING OF THE SECTIONAL CHART WHICH LED ME TO ASSUME THAT V229 WAS STRAIGHT AND CAUSED ME TO OMIT GARED INTXN WHERE IT DOGLEGS. COM WITH ATC WAS NOT A FACTOR. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT THIS INCIDENT WAS TOTALLY PLT ERROR. THE GPS SYS DOES NOT LIST AIRWAYS AND; THEREFORE; THE OPERATOR MUST ENTER EACH NAVAID IDENT AND THEN THE WAYPOINT BTWN NAVAIDS IF ITS TRACK IS NOT A STRAIGHT LINE.
