Timed Approach Procedures Using a Bearing on an
NDB and Longitudinal and Vertical Separation
NOTEFIG
6-7-2 depicts the application of timed approach
procedures using a holding/approach fix on a bearing of an
NDB and applying a combination of longitudinal and
vertical separation. The #3 aircraft has been instructed to
descend to 2,000 after the #2 aircraft has reported
departing the holding/approach fix inbound and leaving
2,000 at point A. The #2 aircraft has departed the
holding/approach fix inbound at the designated time,
maintaining 2,000 until cleared for approach at point A.
The #1 aircraft has been sighted, enabling the controller to
issue approach clearance to the #2 aircraft at point A.
c. Release the aircraft to the tower before it reaches
the final approach fix.
6-7-3. SEQUENCE INTERRUPTION
Interrupt the established timed approach sequence if
necessary to allow an aircraft to execute a different
type of approach.
6-7-4. LEVEL FLIGHT RESTRICTION
If the weather report indicates an aircraft will be in
IFR conditions over the final approach fix
(nonprecision approach) or the outer marker or the fix
used in lieu of the outer marker (precision approach)
when para 6-7-2, Approach Sequence, subpara b is
applied, clear the second aircraft for an approach
early enough to allow at least 1 minute of level flight
before crossing the final approach fix/outer marker or
the fix used in lieu of the outer marker.
6-7-5. INTERVAL MINIMA
Use a 2-minute or a 5-mile radar interval (except for
a small aircraft behind a heavy aircraft: use a
3-minute or a 6-mile radar interval) as the minimum
between successive approaches and increase the
interval, as necessary, taking into account the:
NOTEIncreased
separation is required for small aircraft behind
heavy aircraft because of the possible effects of wake
turbulence.

a. Relative speeds of the aircraft concerned.
b. Existing weather conditions.
c. Distance between the approach fix and the
airport.
d. Type of approach being made.
6-7-6. TIME CHECK
Issue a time check to an aircraft before specifying a
time to leave the approach fix inbound unless the
aircraft is vectored to the final approach course.
6-7-7. MISSED APPROACHES
a. If weather conditions are such that an aircraft
will likely miss an approach, issue an alternative
missed approach procedure to the next aircraft.
b. If an aircraft misses an approach, allow the next
aircraft to continue the approach if it has been
assigned an alternative missed approach procedure.
Retain radar control or hold any remaining aircraft at
assigned altitudes until traffic conditions permit the
issuance of approach clearances.
c. When para 6-7-2, Approach Sequence, subpara
b is applied and the first aircraft misses an
approach, retain radar control or clear the second
aircraft to maintain the last assigned altitude
(minimum holding altitude) and return to the
holding/approach fix to hold until traffic conditions
permit the issuance of approach clearances.

Chapter 7. Visual
Section 1. General
7-1-1. CLASS A AIRSPACE
RESTRICTIONS
Do not apply visual separation or issue VFR or
“VFR‐on‐top” clearances in Class A airspace.
7-1-2. VFR CONDITIONS
a. You may clear aircraft to maintain “VFR
conditions” if one of the following conditions exists:
1. The pilot of an aircraft on an IFR flight plan
requests a VFR climb/descent.
2. TERMINAL. The clearance will result in
noise abatement benefits where part of the IFR
departure route does not conform to an FAAapproved
noise abatement route or altitude.
PHRASEOLOGYMAINTAIN
VFR CONDITIONS.
MAINTAIN VFR CONDITIONS UNTIL (time or fix).
MAINTAIN VFR CONDITIONS ABOVE/BELOW
(altitude).
CLIMB/DESCEND VFR,
and if required,
BETWEEN (altitude) AND (altitude)
or
ABOVE/BELOW (altitude).
b. When, in your judgment, there is reason to
believe that flight in VFR conditions may become
impractical, issue an alternative clearance which will
ensure separation from all other aircraft for which
you have separation responsibility.
PHRASEOLOGYIF
UNABLE, (alternative procedure), AND ADVISE.
7-1-3. APPROACH CONTROL SERVICE
FOR VFR ARRIVING AIRCRAFT
Issue the following where procedures have been
established for arriving VFR aircraft to contact
