Departure Procedures

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 proce-

dure 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 differ-

ent 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 com-

pliance with the ODP is necessary for aircraft to

aircraft separation. Pilots may use the ODP to help

ensure separation from terrain and obstacles.

e.

Responsibilities

1.

Each pilot, prior to departing an airport on an

IFR flight should:

(a)

Consider the type of terrain and other ob-

stacles 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 per-

formance 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.

2.

Pilots should not exceed a published speed re-

striction associated with a SID waypoint until passing

that waypoint.

3.

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;”

 

pi-

lots should then be prepared to rejoin the SID at a

subsequent fix or procedure leg. ATC may also inter-

rupt the vertical navigation of a SID and provide

alternate altitude instructions while the aircraft re-

mains established on the published lateral path.

Aircraft may not be vectored off of an ODP or issued

an altitude lower than a published altitude on an ODP

until at or above the MVA/MIA, at which time the

ODP is canceled.

4.

Aircraft instructed to resume a procedure

such as a DP or SID which contains speed and/or alti-

tude restrictions, must be:

(a)

Issued/reissued all applicable restrictions,

or

(b)

Advised to comply with restrictions or re-

sume published speed.

EXAMPLE

−

“Resume the Solar One departure, comply with restric-
tions.”
“Proceed direct CIROS, resume the Solar One departure,
comply with restrictions.”

5.

A clearance for a SID which contains pub-

lished altitude restrictions may be issued using the

phraseology “climb via.” Climb via is an abbreviated

clearance that requires compliance with the proced-

ure lateral path, associated speed and altitude

restrictions along the cleared route or procedure.

Clearance to “climb via” authorizes the pilot to:

(a)

When used in the IFR departure clearance,

in a PDC, DCL or when cleared to a waypoint depic-

ted on a SID, to join the procedure after departure or

to resume the procedure.

(b)

When vertical navigation is interrupted

and an altitude is assigned to maintain which is not

contained on the published procedure, to climb from

that previously-assigned altitude at pilot’s discretion

to the altitude depicted for the next waypoint.

(c)

Once established on the depicted depar-

ture, to navigate laterally and climb to meet all

published or assigned altitude and speed restrictions.

NOTE

−

1. When otherwise cleared along a route or procedure that
contains published speed restrictions, the pilot must com-
ply with those speed restrictions independent of a climb via
clearance.
