see and avoid other traffic while operating in VFR
conditions (14 CFR Section91.113). In addition to
the normal IFR separation minimums (which
includes visual separation) during VFR conditions,
500 feet vertical separation may be applied between
VFR aircraft and between a VFR aircraft and an IFR
aircraft. Pilots not on IFR flight plans desiring
practice instrument approaches should always state
practice" when making requests to ATC. Controllers
will instruct VFR aircraft requesting an instrument
approach to maintain VFR. This is to preclude
misunderstandings between the pilot and controller
as to the status of the aircraft. If the pilot wishes to
proceed in accordance with instrument flight rules,
he/she must specifically request and obtain an IFR
clearance.
19.2Before practicing an instrument approach,
pilots should inform the approach control facility or
the tower of the type of practice approach they desire
to make and how they intend to terminate it;
i.e.,full−stop landing, touch−and−go, or missed/low
approach maneuver. This information may be
furnished progressively when conducting a series of
approaches. Pilots on an IFR flight plan, who have
made a series of instrument approaches to full stop
landings, should inform ATC when they make their
final landing. The controller will control flights
practicing instrument approaches so as to ensure that
they do not disrupt the flow of arriving and departing
itinerant IFR or VFR aircraft. The priority afforded
itinerant aircraft over practice instrument approaches
is not intended to be so rigidly applied that it causes
a grossly inefficient application of services. A
minimum delay to itinerant traffic may be appropriate
to allow an aircraft practicing an approach to
complete that approach.
NOTE−
A clearance to land means that appropriate separation on
the landing runway will be ensured. A landing clearance
does not relieve the pilot from compliance with any
previously issued restriction.
19.3At airports without a tower, pilots wishing to
make practice instrument approaches should notify
the facility having control jurisdiction of the desired
approach as indicated on the approach chart. All
approach control facilities and ARTCCs are required
to publish a Letter to Airmen depicting those airports
where they provide standard separation to both VFR
and IFR aircraft conducting practice instrument
approaches.
19.4The controller will provide approved separation
between both VFR and IFR aircraft when
authorization is granted to make practice approaches
to airports where an approach control facility is
located and to certain other airports served by
approach control or an ARTCC. Controller responsibility
for separation of VFR aircraft begins at the
point where the approach clearance becomes
effective or when the aircraft enters Class B or TRSA
airspace whichever comes first.
19.5VFR aircraft practicing instrument approaches
are not automatically authorized to execute the
missed approach procedure. This authorization must
be specifically requested by the pilot and approved by
the controller. Separation will not be provided unless
the missed approach has been approved by ATC.
19.6Except in an emergency, aircraft cleared to
practice instrument approaches must not deviate from
the approved procedure until cleared to do so by the
controller.
19.7At radar approach control locations when a full
approach procedure (procedure turn, etc.) cannot be
approved, pilots should expect to be vectored to a
final approach course for a practice instrument
approach which is compatible with the general
direction of traffic at that airport.
19.8When granting approval for a practice
instrument approach, the controller will usually ask
the pilot to report to the tower prior to or over the final
approach fix inbound (nonprecision approaches) or
over the outer marker or fix used in lieu of the outer
marker inbound (precision approaches).

19.9When authorization is granted to conduct
practice instrument approaches to an airport with a
tower but where approved standard separation is not
provided to aircraft conducting practice instrument
approaches, the tower will approve the practice
approach, instruct the aircraft to maintain VFR, and
issue traffic information, as required.

Airport Advisory Service of intent to conduct a
