be applied to a navigation solution one at a time or  in combination. Some FMS provide for the detection  and isolation of faulty navigation information.  Historically, departure procedures were built around  existing ground-based technology and were typically  designed to accommodate lower traffic volumes. Often,  departure and arrival routes use the same NAVAIDs creating  1-30  When you accept a clearance to depart using a SID or radar  vectors, ATC is responsible for traffic separation. When  departing with a SID, ATC expects you to fly the procedure as  charted because the procedure design considers obstacle  clearance. It is also expected that you will remain vigilant  in scanning for traffic when departing in visual conditions.  Furthermore, it is your responsibility to notify ATC if your  clearance would endanger your safety or the safety of others.  DPs are also categorized by equipment requirements  as follows:  SID procedure in your possession at the time of departure.  It is your responsibility as pilot in command to accept or  reject the issuance of a SID by ATC. You must accept or  reject the clearance based on:  • The ability to comply with the required performance.  • The ability to navigate to the degree of accuracy  required for the procedure.  • Possession of the charted SID procedure.  • Personal understanding of the SID in its entirety.  • Non-RNAV DP—established for aircraft equipped  with conventional avionics using ground-based  NAVAIDs.These DPs may also be designed using dead  reckoning navigation. Some flight management  systems (FMS) are certified to fly a non-RNAV DP  if the FMS unit accepts inputs from conventional  avionics sources, such as DME, VOR, and localizer  (LOC). These inputs include radio tuning and may  • RNAV DP—established for aircraft equipped with  RNAV avionics (e.g., GPS, VOR/DME, DME/DME).  Automated vertical navigation is not required,  and all RNAV procedures not requiring GPS must  be annotated with the note: “RADAR REQUIRED.”  Prior to using TSO-C129 GPS equipment for RNAV  departures, approach receiver autonomous integrity  monitoring (RAIM) availability should be checked for  that location.  • Radar DP—radar may be used for navigation  guidance for SID design. Radar SIDs are established  when ATC has a need to vector aircraft on departure  to a particular ATS Route, NAVAID, or fix. A fix may  be a ground-based NAVAID, a waypoint, or defined  by reference to one or more radio NAVAIDs. Not all  fixes are waypoints since a fix could be a VOR or VOR/  DME, but all waypoints are fixes. Radar vectors may  also be used to join conventional or RNAV navigation  SIDs. SIDs requiring radar vectors must be annotated  “RADAR REQUIRED.”  Area Navigation (RNAV) Departures  Figure 1-27. RNP departure levels.  1.0 NM 1.0 NM  2.0 NM 2.0 NM Path centerline
