Section 5. Charted VFR Flyway
Planning Chart Program
11-5-1. DEFINITION
VFR flyways are general flight
paths not defined as a specific course, for use by
pilots in planning flights into, out of, through, or
near complex terminal airspace to avoid Class B
airspace. An ATC clearance is NOT required to fly
these routes.
11-5-2. CRITERIA
Use the following criteria for
establishing VFR Flyway Planning Charts:
a. Flyway Course: The
flight paths used to describe VFR flyways, must, to
the maximum extent practicable, reference ground
objects that can be readily identified from the air.
If necessary, and if an operational benefit can be
derived, radio NAVAID references may be used.
b. Flyway Altitudes: Each
segment of a charted VFR flyway should contain
recommended altitudes.
1. Recommended altitudes
must avoid airspace requiring prior authorization or
clearance to enter.
2. Care should be exercised
to avoid recommending altitudes which could cause the
aircraft on a flyway to encounter inflight wake
turbulence generated by large aircraft.
3. When altitude changes are
required, they should be based on a descent rate of
250-350 feet per nautical mile.
c. Altitude Compression:
Charted VFR flyways established under the floors of
Class B airspace require careful evaluation to avoid
compression of the airspace and the altitudes
available for VFR operations.
d. Military Considerations:
Avoid establishing VFR Flyways which would conflict
with military ground control radar approach paths.
When charting VFR flyways which cross or are in
proximity to an MTR, include communications
instructions for pilots to determine the status of the
MTR.
e. Once a flyway is charted,
it will only be moved when it significantly interferes
with other operations.
11-5-3. RESPONSIBILITIES
a. Flyway Development:
The facility air traffic manager develops
requirements for VFR flyways charting. All actions
leading to the development of a VFR Flyway Planning
Chart should be initiated by the facility air traffic
manager.
1. Initial Action: The
requesting facility air traffic manager must establish
a task force of air traffic, FSDO, military, and local
aviation interests, as appropriate, to recommend where
the charted VFR flyways should be located.
2. Flyway Justification: As
a minimum, the facility air traffic manager must
address in writing the following pertinent factors:
(a) Background information
pertaining to the development of the chart, such as
the composition of the task group.
(b) The major areas
examined.
(c) Special VFR procedures.
(d) Recommendations by the
task group.
(e) Reasons supporting the
establishment of a VFR Flyway Planning Chart for the
area.
3. Charts and Description: A
narrative description of the flyway and the
appropriate VFR Terminal Area Chart or a drawing must
depict the following data:
(a) VFR flyway flight paths
with named visual checkpoints, NAVAID magnetic
radials, and altitudes;
(b) Any large
turbine-powered aircraft arrival/departure routes that
cross the charted VFR flyway;
(c) Procedural notes
positioned on the drawing or the VFR TAC; and
(d) The communication
frequencies if frequencies are recommended for
advisories. Indicate the flyway segment/s associated
with each frequency.
b. Flyway Approval:
Terminal Operations Service Area Offices are
responsible for approving the proposed VFR Flyway
Planning Charts and ensuring that they comply with the
prescribed criteria. If approval is granted, the
Terminal Operations Area Offices must forward the
proposal to System Operations Airspace and
Aeronautical Information Office at least 9 weeks prior
to the planned implementation date. The planned
implementation date must coincide with a publication
date of the respective VFR TAC.
c. Annual Review: Terminal
Operations Area Offices are responsible for reviewing
existing VFR Flyway Planning Charts on an annual basis
to determine their continued need.
d. Revision to Flyways: In
order that System Operations Airspace and Aeronautical
Information Office can meet its responsibilities,
revisions to VFR Flyway Planning Charts must be
submitted to System Operations Airspace and
Aeronautical Information Office at least 9 weeks prior
to the publication date of the respective VFR Terminal
Area Chart. Revisions may be initiated by the facility
air traffic manager or the Terminal Operations Area
Office. The following are considered sufficient
justification to warrant revision:
1. Changes, additions, or
deletions to VFR flyways or altitudes, frequencies,
procedural notes, or changes to airport status; i.e.,
name, closed, abandoned, etc.
2. Changes in large
turbine-powered aircraft arrival/departure routes.
3. Additions or deletions to
checkpoints/NAVAIDs.
e. Publicity: The facility
air traffic manager must seek the cooperation of the
FSDO in informing aviation interests about the VFR
Flyway Planning Chart Program. Special emphasis should
be placed on:
1. Pilot adherence to
flyways and recommended altitudes is voluntary.
2. Flyways are not devoid of
IFR or military traffic. They represent flight paths
that are believed to have the least IFR or military
activity.
3. A “see and avoid”
environment must be maintained and emphasized.
