Airport Master Plan - City of Riverside

percent of the national fleet do not
conduct a sufficient number of operations
at the airport to be considered
for a runway extension.
There are two circumstances under
which the runway length may not be
adequate and a runway extension may
be considered. The first is if business
jets which fall in the category of 100
percent of the national fleet base at
the airport and combine for at least
500 annual operations. Typical aircraft
types include the Challenger 604,
the Citation X, the Learjet 55 and 60,
and the Hawker 800XP or 1000.
These based operators would also have
to provide documentation of the number
of annual operations and runway
length requirements to justify this
need to the FAA and qualify for funding
assistance.
The second circumstance would be if
the number of annual operations by
transient business jets in the 100 percent
of the national fleet category were
to exceed 500. This information is
more difficult to determine and document.
In the past, the FAA has accepted
formal letters from transient
operators expressing a need for greater
runway length and outlining the
economic impacts to their operation of
utilizing a shorter runway than desired.
Currently, there are no based
business jets in the 100 percent of the
national fleet category.
In conclusion, the primary runway
length meets the current needs of both
based and transient airport users. It
would be recommended that airport
management closely monitor itinerant
activity by business jets within the
100 percent of the national fleet category
and be aware of the introduction
of any owners of business jets within
this category wishing to base at Riverside
Airport. The combination of activity
by these two sources of large
business jet operations could lead to a
need for an extension of the primary
runway. The need for a runway extension
would have to be thoroughly
documented and justified.
If the possibility of a runway extension
were to be pursued, there are
several factors that could limit the potential
length of an extension. As
shown in Table 3H, to accommodate
100 percent of the business jet fleet,
an optimal runway length of up to
6,400 feet may be necessary. The location
of the railroad spur, 475 feet to
the west of the Runway 9 threshold,
limits any extension to the Runway 27
end. Since the completion of the previous
master plan in 1999, the FAA
has taken a strict interpretation on
meeting design standards, and not
supporting airfield improvements that
build into a non-standard situation.
For example, an extension to the east
of Riverside Airport would position the
RPZ serving Runway 27 over Hillside
Avenue and over approximately 70
homes. The road and the homes
would be incompatible with the design
standards of the RPZ. Hillside Avenue
would have to be closed and the
homes would have to be purchased
and removed.
While an extension of Runway 9-27 is
not currently justified, in the future,
operational need may warrant a reexamination.
