In the event of GNSS interference at OTHH where aircraft are unable to fly the RNP SID, ATC may issue the following runway-specific departure instructions: RWY 34L — maintain runway track and climb to altitude 3000FT, expect to rejoin assigned SID; RWY 34R — passing 500FT, turn right heading 040 degrees and climb to altitude 4000FT, expect to rejoin assigned SID; RWY 16L — passing 500FT, turn left heading 120 degrees and climb to altitude 4000FT, expect to rejoin assigned SID; RWY 16R — maintain runway track and climb to altitude 3000FT, expect to rejoin assigned SID. Aircraft must advise ATC when able to resume navigation using RNAV/RNP.
