Wapp gomb1a sid

The text given on the Jeppeson Chart for the WAPP GOMB1A SID reads:
“At D20.0 AMN, turn LEFT heading 090º until crossing AMN R180 at 3500, turn left heading 070º to GOMBY”
However the Navigraph route turns left at R180 and tracks directly to the AMN VOR before joining the W54 airway to route to GOMBY.
Which is correct?


Hi Mike,

The Jeppesen chart description is correct and corresponds to Navigraph Navigational Data.

We shall investigate.
