1. In Example 2, pilots are expected to descend to FL 240
as directed, and maintain FL 240 until cleared for further
vertical navigation with a newly assigned altitude or a
“descend via” clearance.
2. In Example 4, the aircraft should track laterally and
vertically on the Haris One arrival and should descend so
as to comply with all speed and altitude restrictions until

reaching Bruno and then maintain 10,000. Upon reaching
10,000, aircraft should maintain 10,000 until cleared by
ATC to continue to descend.
(b) Pilots cleared for vertical navigation
using the phraseology “descend via” shall inform
ATC upon initial contact with a new frequency.
EXAMPLE−
“Delta One Twenty One leaving FL 240, descending via
the Civit One arrival.”
b. Pilots of IFR aircraft destined to locations for
which STARs have been published may be issued a
clearance containing a STAR whenever ATC deems
it appropriate.
c. Use of STARs requires pilot possession of at
least the approved chart. RNAV STARs must be
retrievable by the procedure name from the aircraft
database and conform to charted procedure. As with
any ATC clearance or portion thereof, it is the
responsibility of each pilot to accept or refuse an
issued STAR. Pilots should notify ATC if they do not
wish to use a STAR by placing “NO STAR” in the
remarks section of the flight plan or by the less
desirable method of verbally stating the same to ATC.
d. STAR charts are published in the Terminal
Procedures Publications (TPP) and are available on
subscription from the National Aeronautical Charting
Office, AVN−500.
e. RNAV STAR.
Procedure Design. An RNAV STAR is
designed using criteria similar to Level 2 DP.
5−4−2. Local Flow Traffic Management
Program
a. This program is a continuing effort by the FAA
to enhance safety, minimize the impact of aircraft
noise and conserve aviation fuel. The enhancement of
safety and reduction of noise is achieved in this
program by minimizing low altitude maneuvering of
arriving turbojet and turboprop aircraft weighing
more than 12,500 pounds and, by permitting
departure aircraft to climb to higher altitudes sooner,
as arrivals are operating at higher altitudes at the
points where their flight paths cross. The application
of these procedures also reduces exposure time
between controlled aircraft and uncontrolled aircraft
at the lower altitudes in and around the terminal
environment. Fuel conservation is accomplished by
absorbing any necessary arrival delays for aircraft
included in this program operating at the higher and
more fuel efficient altitudes.
b. A fuel efficient descent is basically an
uninterrupted descent (except where level flight is
required for speed adjustment) from cruising altitude
to the point when level flight is necessary for the pilot
to stabilize the aircraft on final approach. The
procedure for a fuel efficient descent is based on an
altitude loss which is most efficient for the majority
of aircraft being served. This will generally result in
a descent gradient window of 250−350 feet per
nautical mile.
c. When crossing altitudes and speed restrictions
are issued verbally or are depicted on a chart, ATC
will expect the pilot to descend first to the crossing
altitude and then reduce speed. Verbal clearances for
descent will normally permit an uninterrupted
descent in accordance with the procedure as
described in paragraph b above. Acceptance of a
charted fuel efficient descent (Runway Profile
Descent) clearance requires the pilot to adhere to the
altitudes, speeds, and headings depicted on the charts
unless otherwise instructed by ATC. PILOTS
RECEIVING A CLEARANCE FOR A FUEL
EFFICIENT DESCENT ARE EXPECTED TO
ADVISE ATC IF THEY DO NOT HAVE RUNWAY

5−4−3. Approach Control
a. Approach control is responsible for controlling
all instrument flight operating within its area of
responsibility. Approach control may serve one or
more airfields, and control is exercised primarily by
direct pilot and controller communications. Prior to
arriving at the destination radio facility, instructions
will be received from ARTCC to contact approach
control on a specified frequency.
b. Radar Approach Control.
1. Where radar is approved for approach control
service, it is used not only for radar approaches
