Departure Procedures

4. Aircraft instructed to resume a SID procedure

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

altitude restrictions, must be:

(a) Issued/reissued all applicable restrictions,

or

(b) Advised to “Climb via SID” or resume

published speed.

EXAMPLE−

“Resume the Solar One departure, Climb via SID.”

“Proceed direct CIROS, resume the Solar One departure,

Climb via SID.”

5. A clearance for a SID which does not contain

published crossing restrictions, and/or is a SID with

a Radar Vector segment or a Radar Vector SID, will

be issued using the phraseology “Maintain (alti-

tude).”

6. A clearance for a SID which contains

published altitude restrictions may be issued using

the phraseology “climb via.” Climb via is an

abbreviated clearance that requires compliance with

the procedure 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

depicted 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.
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.

FAA Order JO 7110.65, Paragraph 5-6-2, Methods

PCG, Climb Via, Top Altitude

EXAMPLE−
1. Lateral route clearance:

“Cleared Loop Six departure.”

NOTE−

The aircraft must comply with the SID lateral path, and any

published speed restrictions.
2. Routing with assigned altitude:

“Cleared Loop Six departure, climb and maintain

four thousand.”
NOTE−

The aircraft must comply with the SID lateral path, and any

published speed restriction while climbing unrestricted to

four thousand.
3. (A pilot filed a flight plan to the Johnston Airport using
the Scott One departure, Jonez transition, then Q-145. The
pilot filed for FL350. The Scott One includes altitude
restrictions, a top altitude and instructions to expect the
filed altitude ten minutes after departure). Before
departure ATC uses PDC, DCL or clearance delivery to
issue the clearance:

“Cleared to Johnston Airport, Scott One departure,

Jonez transition, Q-OneForty-five. Climb via SID.”
NOTE−

In Example 3, the aircraft must comply with the Scott One

departure lateral path and any published speed and

altitude restrictions while climbing to the SID top altitude.
4. (Using the Example 3 flight plan, ATC determines the
top altitude must be changed to FL180). The clearance will
read: 

“Cleared to Johnston Airport, Scott One departure,

Jonez transition, Q-One Forty-five, Climb via SID except
maintain flight level one eight zero.”
NOTE−

In Example 4, the aircraft must comply with the Scott One
