effective, efficient terminal operations, thereby increasing

If you cannot comply with a SID, if you do not possess
SID charts or textual descriptions, or if you simply do
not wish to use standard instrument departures, include
the statement “NO SIDs” in the remarks section of your
flight plan. Doing so notifies ATC that they cannot issue
you a clearance containing a SID, but instead will clear
you via your filed route to the extent possible, or via a
Preferential Departure Route (PDR). It should be
noted that SID usage not only decreases clearance
delivery time, but also greatly simplifies your departure, easing you into the IFR structure at a desirable
location and decreasing your flight management load.
While you are not required to depart using a SID, it may
be more difficult to receive an “as filed” clearance when
departing busy airports that frequently use SID routing.
SIDs are always charted graphically and are located in
the TPP after the last approach chart for an airport. The
SID may be one or two pages in length, depending on the
size of the graphic and the amount of space required for
the departure description. Each chart depicts the departure route, navigational fixes, transition routes, and
required altitudes. The departure description outlines the
particular procedure for each runway. [Figure 2-21 on
page 2-20]
Charted transition routes allow pilots to transition from
the end of the basic SID to a location in the en route
structure. Typically, transition routes fan out in various
directions from the end of the basic SID to allow pilots
to choose the transition route that takes them in the

direction of intended departure. A transition route
includes a course, a minimum altitude, and distances
between fixes on the route. When filing a SID for a specific transition route, include the transition in the flight
plan, using the correct departure and transition code.
ATC also assigns transition routes as a means of putting
the flight on course to the destination. In any case, the
pilot must receive an ATC clearance for the departure

and the associated transition, and the clearance from
ATC will include both the departure name and transition e.g., Joe Pool Nine Departure, College Station
Transition. [Figure 2-22]
PILOT NAV AND VECTOR SIDS
SIDs are categorized by the type of navigation used to
fly the departure, so they are considered either pilot navigation or vector SIDs. Pilot navigation SIDs are

designed to allow you to provide your own navigation
with minimal radio communication. This type of procedure usually contains an initial set of departure
instructions followed by one or more transition routes.
A pilot navigation SID may include an initial segment
requiring radar vectors to help the flight join the procedure, but the majority of the navigation will remain
the pilot’s responsibility. These are the most common
type of SIDs because they reduce the workload for
ATC by requiring minimal communication and navigation support. [Figure 2-23].
A Vector SID usually requires ATC to provide radar
vectors from just after takeoff (ROC is based on a climb
to 400 feet above the DER elevation before making the
initial turn) until reaching the assigned route or a fix
depicted on the SID chart. However, some textual
ODPs originate in uncontrolled airspace, while the SID
begins in controlled airspace. Vector SIDs do not
include departure routes or transition routes because
independent pilot navigation is not involved. The procedure sets forth an initial set of departure instructions
that typically include an initial heading and altitude.
ATC must have radar contact with the aircraft to be able
to provide vectors. ATC expects you to immediately
comply with radar vectors and they expect you to notify
them if you are unable to fulfill their request. ATC also
expects you to make contact immediately if an instruction will cause you to compromise safety due to
obstructions or traffic.
It is prudent to review vector SID charts prior to use
because this type of procedure often includes nonstandard lost communication procedures. If you were to
lose radio contact while being vectored by ATC, you
would be expected to comply with the lost communication procedure as outlined on the chart, not necessarily
those procedures outlined in the AIM. [Figure 2-24 on
page 2-24]
