Departure Procedures

departure lateral path and any published speed and
altitude restrictions while climbing to FL180. The aircraft
must stop climb at FL180 until issued further clearance by
ATC.

5.

(An aircraft was issued the Suzan Two departure,

“climb via SID” in the IFR departure clearance. After
departure ATC must change a waypoint crossing
restriction). The clearance will be:

“Climb via SID except cross Mkala at or above seven

thousand.”

NOTE

−

In Example 5, the aircraft will comply with the Suzan Two
departure lateral path and any published speed and
altitude restrictions and climb so as to cross Mkala at or
above 7,000; remainder of the departure must be flown as
published.

6.

(An aircraft was issued the Teddd One departure,

“climb via SID” in the IFR departure clearance. An
interim altitude of 10,000 was issued instead of the
published top altitude of FL 230). After departure ATC is
able to issue the published top altitude. The clearance will
be:

“Climb via SID.”

NOTE

−

In Example 6, the aircraft will track laterally and vertically
on the Teddd One departure and initially climb to 10,000;
Once re-issued the “climb via” clearance the interim
altitude is canceled aircraft will continue climb to FL230
while complying with published restrictions.

7.

(An aircraft was issued the Bbear Two departure,

“climb via SID” in the IFR departure clearance. An
interim altitude of 16,000 was issued instead of the
published top altitude of FL 190). After departure, ATC is
able to issue a top altitude of FL300 and still requires
compliance with the published SID restrictions. The
clearance will be: 

“Climb via SID except maintain flight level three zero

zero.”

NOTE

−

In Example 7, the aircraft will track laterally and vertically
on the Bbear Two departure and initially climb to 16,000;
Once re-issued the “climb via” clearance the interim
altitude is canceled and the aircraft will continue climb to
FL300 while complying with published restrictions.

8.

(An aircraft was issued the Bizee Two departure, “climb

via SID.” After departure, ATC vectors the aircraft off of
the SID, and then issues a direct routing to rejoin the SID
at Rockr waypoint which does not have a published altitude
restriction. ATC wants the aircraft to cross at or above
10,000). The clearance will read:

“Proceed direct Rockr, cross Rockr at or above

one-zero thousand, climb via the Bizee Two departure.”

NOTE

−

In Example 8, the aircraft will join the Bizee Two SID at
Rockr at or above 10,000 and then comply with the
published lateral path and any published speed or altitude
restrictions while climbing to the SID top altitude.

9.

(An aircraft was issued the Suzan Two departure,

“climb via SID” in the IFR departure clearance. After
departure ATC vectors the aircraft off of the SID, and then
clears the aircraft to rejoin the SID at Dvine waypoint,
which has a published crossing restriction). The clearance
will read:

 “Proceed direct Dvine, Climb via the Suzan Two

departure.”

NOTE

−

In Example 9, the aircraft will join the Suzan Two departure
at Dvine, at the published altitude, and then comply with
the published lateral path and any published speed or
altitude restrictions.

7.

Pilots cleared for vertical navigation using the

phraseology “climb via” must inform ATC, upon
initial contact, of the altitude leaving and any
assigned restrictions not published on the procedure.

EXAMPLE

−

1.

(Cactus 711 is cleared to climb via the Laura Two

departure. The Laura Two has a top altitude of FL190): 
“Cactus Seven Eleven leaving two thousand, climbing via
the Laura Two departure.”

2.

(Cactus 711 is cleared to climb via the Laura Two

departure, but ATC changed the top altitude to16,000): 
“Cactus Seven Eleven leaving two thousand for one-six
thousand, climbing via the Laura Two departure.”

8.

If prior to or after takeoff an altitude

restriction is issued by ATC, all previously issued
“ATC” altitude restrictions are canceled including
those published on a SID. Pilots must still comply
with all speed restrictions and lateral path require-
ments published on the SID unless canceled by ATC.

EXAMPLE

−

Prior to takeoff or after departure ATC issues an altitude
change clearance to an aircraft cleared to climb via a SID
but ATC no longer requires compliance with published
altitude restrictions:

“Climb and maintain flight level two four zero.”

NOTE

−

The published SID altitude restrictions are canceled; The
aircraft should comply with the SID lateral path and begin
an unrestricted climb to FL240. Compliance with
published speed restrictions is still required unless
specifically deleted by ATC.

9.

Altitude restrictions published on an ODP are

necessary for obstacle clearance and/or design
