Departure Procedures

nautical mile) required by the departure procedure or
DVA, and be aware that flying at a higher than
anticipated ground speed increases the climb rate
requirement in feet per minute. Higher than standard
climb gradients are specified by a note on the
departure procedure chart for graphic DPs, or in the
Take

−Off Minimums and (Obstacle) Departure

Procedures section of the U.S. Terminal Procedures
booklet for textual ODPs. The required climb
gradient, or higher, must be maintained to the
specified altitude or fix, then the standard climb
gradient of 200 ft/NM can be resumed. A table for the
conversion of climb gradient (feet per nautical mile)
to climb rate (feet per minute), at a given ground
speed, is included on the inside of the back cover of
the U.S. Terminal Procedures booklets.

Where are DPs located? DPs and DVAs will be

listed by airport in the IFR Takeoff Minimums and
(Obstacle) Departure Procedures Section, Section L,
of the Terminal Procedures Publications (TPP). If the
DP is textual, it will be described in TPP Section L.
SIDs and complex ODPs will be published
graphically and named. The name will be listed by
airport name and runway in Section L. Graphic ODPs
will also have the term “(OBSTACLE)” printed in the
charted procedure title, differentiating them from
SIDs.

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 takeoff 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.

Responsibilities

1.

Each pilot, prior to departing an airport on an

IFR flight should: 

(a)

Consider the type of terrain and other

obstacles on or in the vicinity of the departure airport;

(b)

Determine whether an ODP is available;

(c)

Determine if obstacle avoidance can be

maintained visually or if the ODP should be flown;
and

(d)

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 V

1

 speed on a large or

turbine

−powered transport category airplane may be

found in AC 120

−91, Airport Obstacle Analysis.

(e)

Determine if a DVA is published and

whether the aircraft is capable of meeting the
published climb gradient. Advise ATC when
requesting the IFR clearance, or as soon as possible,
if  unable to meet the DVA climb gradient.

(f)

Check for Takeoff Obstacle Notes pub-

lished in the TPP for the takeoff runway.

2.

Pilots should not exceed a published speed

restriction associated with a SID waypoint until
passing that waypoint.

3.

After an aircraft is established on a SID and

subsequently vectored or cleared to deviate off of the
SID or SID transition, pilots must consider the SID
canceled, unless the controller adds “expect to
resume SID;”

 

pilots should then be prepared to rejoin

the SID at a subsequent fix or procedure leg. If the
SID contains published altitude restrictions, pilots
should expect the controller to issue an altitude to
maintain. ATC may also interrupt the vertical
navigation of a SID and provide alternate altitude
instructions while the aircraft remains established on
the published lateral path. Aircraft may be vectored
off of an ODP, or issued an altitude lower than a
published altitude on an ODP, at which time the ODP
is canceled and ATC is responsible for terrain and
obstacle clearance. In all cases, the minimum 200
FPNM climb gradient is assumed.
