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.

g. 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.

h. 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.
