be pronounceable, and they are not for use in ATC
communications. On VFR charts, stand−alone VFR
waypoints will be portrayed using the same
four−point star symbol used for IFR waypoints. VFR
waypoints collocated with visual check points on the
chart will be identified by small magenta flag
symbols. VFR waypoints collocated with visual
check points will be pronounceable based on the
name of the visual check point and may be used for
ATC communications. Each VFR waypoint name
will appear in parentheses adjacent to the geographic
location on the chart. Latitude/longitude data for all
established VFR waypoints may be found in the
appropriate regional Airport/Facility Directory
(A/FD).
3. VFR waypoints shall not be used to plan
flights under IFR. VFR waypoints will not be
recognized by the IFR system and will be rejected for
IFR routing purposes.
4. When filing VFR flight plans, pilots may use
the five letter identifier as a waypoint in the route of
flight section if there is an intended course change at
that point or if used to describe the planned route of
flight. This VFR filing would be similar to how a
VOR would be used in a route of flight. Pilots must
use the VFR waypoints only when operating under
VFR conditions.

5. Any VFR waypoints intended for use during
a flight should be loaded into the receiver while on the
ground and prior to departure. Once airborne, pilots
should avoid programming routes or VFR waypoint
chains into their receivers.
6. Pilots should be especially vigilant for other
traffic while operating near VFR waypoints. The
same effort to see and avoid other aircraft near VFR
waypoints will be necessary, as was the case with
VORs and NDBs in the past. In fact, the increased
accuracy of navigation through the use of GPS will
demand even greater vigilance, as off−course
deviations among different pilots and receivers will
be less. When operating near a VFR waypoint, use
whatever ATC services are available, even if outside
a class of airspace where communications are
required. Regardless of the class of airspace, monitor
the available ATC frequency closely for information
on other aircraft operating in the vicinity. It is also a
good idea to turn on your landing light(s) when
operating near a VFR waypoint to make your aircraft
more conspicuous to other pilots, especially when
visibility is reduced. See paragraph 7−5−2, VFR in
Congested Areas, for more information.
d. General Requirements
1. Authorization to conduct any GPS operation
under IFR requires that:
(a) GPS navigation equipment used must be
approved in accordance with the requirements
specified in Technical Standard Order (TSO)
TSO−C129, or equivalent, and the installation must
be done in accordance with Advisory Circular
AC 20−138, Airworthiness Approval of Global
Positioning System (GPS) Navigation Equipment for
Use as a VFR and IFR Supplemental Navigation
System, or Advisory Circular AC 20−130A, Airworthiness
Approval of Navigation or Flight Management
Systems Integrating Multiple Navigation
Sensors, or equivalent. Equipment approved in
accordance with TSO−C115a does not meet the
requirements of TSO−C129. Visual flight rules
(VFR) and hand−held GPS systems are not
authorized for IFR navigation, instrument approaches,
or as a principal instrument flight
reference. During IFR operations they may be
considered only an aid to situational awareness.
(b) Aircraft using GPS navigation equipment
under IFR must be equipped with an approved and
operational alternate means of navigation appropriate
to the flight. Active monitoring of alternative
navigation equipment is not required if the GPS
receiver uses RAIM for integrity monitoring. Active
monitoring of an alternate means of navigation is
required when the RAIM capability of the GPS
equipment is lost.
(c) Procedures must be established for use in
the event that the loss of RAIM capability is predicted
to occur. In situations where this is encountered, the
flight must rely on other approved equipment, delay
departure, or cancel the flight.
(d) The GPS operation must be conducted in
accordance with the FAA−approved aircraft flight
manual (AFM) or flight manual supplement. Flight
crew members must be thoroughly familiar with the
particular GPS equipment installed in the aircraft, the
receiver operation manual, and the AFM or flight
manual supplement. Unlike ILS and VOR, the basic
