specified when required for separation.
NOTETo
preclude the possibility of aircraft exceeding
rate‐of‐descent or airspeed limitations, the maximum
altitudes which may be assigned for any portion of the high
altitude instrument approach procedure will be determined
through coordination between the ATC facility concerned
and the military authority which originated the high
altitude instrument approach procedure.
REFERENCEFAAO
JO 7110.65, Para 4-7-5, Military Turbojet En Route Descent.
4-8-5. SPECIFYING ALTITUDE
Specify in the approach clearance the altitude shown
in the approach procedures when adherence to that
altitude is required for separation. When vertical
separation will be provided from other aircraft by
pilot adherence to the prescribed maximum,
minimum, or mandatory altitudes, the controller may
omit specifying the altitude in the approach
clearance.
NOTEUse
FAA or NIMA instrument approach procedures charts
appropriate for the aircraft executing the approach.
4-8-6. CIRCLING APPROACH
a. Circling approach instructions may only be
given for aircraft landing at airports with operational
control towers.
b. Include in the approach clearance instructions
to circle to the runway in use if landing will be made
on a runway other than that aligned with the direction
of instrument approach. When the direction of the
circling maneuver in relation to the airport/runway is
required, state the direction (eight cardinal compass
points) and specify a left or right base/downwind leg
as appropriate.
PHRASEOLOGYCIRCLE
TO RUNWAY (number),
or
CIRCLE (direction using eight cardinal compass points)
OF THE AIRPORT/RUNWAY FOR A LEFT/RIGHT
BASE/DOWNWIND TO RUNWAY (number).
JO 7110.65S 2/14/08
4-8-6 Approach Clearance Procedures
NOTEWhere
standard instrument approach procedures (SIAPs)
authorize circling approaches, they provide a basic
minimum of 300 feet of obstacle clearance at the MDA
within the circling area considered. The dimensions of
these areas, expressed in distances from the runways, vary
for the different approach categories of aircraft. In some
cases a SIAP may otherwise restrict circling approach
maneuvers.
c. Do not issue clearances, such as “extend
downwind leg,” which might cause an aircraft to
exceed the circling approach area distance from the
runways within which required circling approach
obstacle clearance is assured.
4-8-7. SIDE-STEP MANEUVER
TERMINAL
Side‐step Maneuver. When authorized by an instrument
approach procedure, you may clear an aircraft
for an approach to one runway and inform the aircraft
that landing will be made on a parallel runway.
EXAMPLE-
“Cleared I-L-S Runway seven left approach. Side‐step to
runway seven right.”
NOTESide‐
step maneuvers require higher weather minima/
MDA. These higher minima/MDA are published on the
instrument approach charts.
REFERENCEFAAO
JO 7110.65, Para 3-3-2, Closed/Unsafe Runway Information.
P/CG Term- Side-step Maneuver.
4-8-8. COMMUNICATIONS RELEASE
If an IFR aircraft intends to land at an airport not
served by a tower or FSS, approve a change to the
advisory service frequency when you no longer
require direct communications.
PHRASEOLOGYCHANGE
TO ADVISORY FREQUENCY APPROVED.
NOTEAn
expeditious frequency change permits the aircraft to
receive timely local airport traffic information in
accordance with AC 90-42, Traffic Advisory Practices at
Airports Without Operating Control Towers.
4-8-9. MISSED APPROACH
Except in the case of a VFR aircraft practicing an
instrument approach, an approach clearance automatically
authorizes the aircraft to execute the missed
approach procedure depicted for the instrument
approach being flown. An alternate missed approach
procedure as published on the appropriate FAA
Form8260 or appropriate military form may be
assigned when necessary. Once an aircraft commences
a missed approach, it may be radar vectored.
NOTE-
1. Alternate missed approach procedures are published on
the appropriate FAA Form 8260 or appropriate military
form and require a detailed clearance when they are issued
to the pilot.
2. In the event of a missed approach involving a turn,
unless otherwise cleared, the pilot will proceed to the
missed approach point before starting that turn.
