(c) Determine if obstacle avoidance can be
maintained visually or if the ODP should be flown;
(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.
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.
2. Pilots should not exceed a published speed re-
striction associated with a SID waypoint until passing
3. After an aircraft is established on an 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 re-
sume 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 naviga-
tion of a SID and provide alternate altitude
instructions while the aircraft remains established on
the published lateral path. Aircraft may not be vec-
tored 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,
(b) Advised to comply with restrictions or re-
sume published speed.
"Resume the Solar One departure, comply with restric-
"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.
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
2. ATC anticipates pilots will begin adjusting speed the
minimum distance necessary prior to a published speed re-
striction so as to cross the waypoint/fix at the published
speed. Once at the published speed ATC expects pilots will
maintain the published speed until additional adjustment
is required to comply with further published or ATC as-
signed speed restrictions or as required to ensure
compliance with 14 CFR Section 91.117.
3. If ATC interrupts lateral/vertical navigation while an
aircraft is flying a SID, ATC must ensure obstacle clear-
ance. When issuing a "climb via" clearance to join or
resume a procedure ATC must ensure obstacle clearance
until the aircraft is established on the lateral and vertical
path of the SID.
4. ATC will assign an altitude to cross if no altitude is de-
picted at a waypoint/fix or when otherwise necessary/
required, for an aircraft on a direct route to a waypoint/fix
where the SID will be joined or resumed.
5. SIDs will have a "top altitude;" the "top altitude" is the
charted "maintain" altitude contained in the procedure
description or assigned by ATC.
