36.5 Where are DPs located? DPs will be listed by airport in the IFR Takeoff Minimums and (Obstacle) Departure Procedures Section, Section C, of the Terminal Procedures Publications (TPPs). If the DP is textual, it will be described in TPP Section C. SIDs and complex ODPs will be published graphically and named. The name will be listed by airport name and runway in Section C. Graphic ODPs will also have the term “(OBSTACLE)” printed in the charted procedure title, differentiating them from SIDs.
36.5.1 An ODP that has been developed solely for obstacle avoidance will be indicated with the symbol “T” on appropriate Instrument Approach Procedure (IAP) charts and DP charts for that airport. The “T” symbol will continue to refer users to TPP Section C. In the case of a graphic ODP, the TPP Section C will only contain the name of the ODP. Since there may be both a textual and a graphic DP, Section C should still be checked for additional information. The nonstan-dard minimums and minimum climb gradients found in TPP Section C also apply to charted DPs and radar vector departures unless different minimums are specified on the charted DP. Takeoff minimums and departure procedures apply to all runways unless otherwise specified. New graphic DPs will have all the information printed on the graphic depiction. As a general rule, ATC will only assign an ODP from a nontowered airport when compliance with the ODP is necessary for aircraft to aircraft separation. Pilots may use the ODP to help ensure separation from terrain and obstacles.
36.6 Responsibilities
36.6.1 Each pilot, prior to departing an airport on an IFR flight should:
36.6.1.1 Consider the type of terrain and other obstacles on or in the vicinity of the departure airport;
36.6.1.2 Determine whether an ODP is available;
36.6.1.3 Determine if obstacle avoidance can be maintained visually or if the ODP should be flown; and
36.6.1.4 Consider the effect of degraded climb performance and the actions to take in the event of an engine loss during the departure. Pilots should notify ATC as soon as possible of reduced climb capability in that circumstance.
NOTE.
Guidance concerning contingency procedures that address an engine failure on takeoff after V1 speed on a large or turbine.powered transport category airplane may be found in AC 120.91, Airport Obstacle Analysis.
36.6.2 After an aircraft is established on an SID and subsequently vectored or cleared off of the SID or SID transition, pilots must consider the SID canceled, unless the controller adds “expect to resume SID.” Aircraft may not be vectored off of an ODP until at or above the MVA/MIA, at which time the ODP is canceled.
36.6.3 Aircraft instructed to resume a SID that contains ATC altitude restrictions, shall be issued/ reissued all applicable restrictions or shall be advised to comply with those restrictions.
36.6.4 If prior to or after takeoff an altitude restriction is issued by ATC, all previously issued “ATC” altitude restrictions are cancelled including those published on a SID.
36.6.5 ATC crossing altitude restrictions published on SIDs are identified on the chart with “(ATC)” following the altitude restriction. This will indicate to the pilot and the controller that this restriction is for ATC purposes and may be deleted by ATC. When an ATC crossing altitude has been established prior to the beginning of a transition route, a minimum altitude for obstruction clearance or other design constraints will also be published at the same fix

adjacent/below the “(ATC)” altitude. The absence of “(ATC)” at a “minimum altitude” indicates the restriction is there to support obstacle clearance, airspace restrictions, Navaid reception, and/or other reason(s) that mandate compliance. These altitudes CANNOT be lowered or cancelled by ATC. A standalone “(ATC)” altitude restriction may also be located on a transition route; however, it must never be lower than the published Minimum Enroute Altitude (MEA).
36.6.6 Altitude restrictions published on an ODP are necessary for obstacle clearance and/or design constraints. Compliance with these restrictions is mandatory and CANNOT be lowered or cancelled by ATC.
36.7 RNAV Departure Procedures
36.7.1 All public RNAV SIDs and graphic ODPs are RNAV 1. These procedures generally start with an initial RNAV or heading leg near the departure runway end. In addition, these procedures require system performance currently met by GPS or DME/DME/IRU RNAV systems that satisfy the criteria discussed in AC 90.100A, U.S. Terminal and En Route Area Navigation (RNAV) Operations. RNAV 1 procedures require the aircraft’s total system error remain bounded by 1 NM for 95% of the total flight time.
