RUNWAYS
The adequacy of the existing runway
system at Riverside Airport has been
analyzed from a number of perspectives,
including runway orientation,
runway length, pavement strength,
width, and adherence to safety area
standards. From this information, requirements
for runway improvements
were determined for the airport.
should be made available when the
primary runway orientation provides
for less than 95 percent wind coverage
for specific crosswind components.
The 95 percent wind coverage is computed
on the basis of the crosswind
component not exceeding 10.5 knots
(12 mph) for ARCs A-I and B-I; 13
knots (15 mph) for ARCs A-II and B-
II; and 16 knots (18 mph) for ARC C-I
through D-II.
Runway Orientation
The airport is served by two intersecting
runways. Runway 9-27 is oriented
in an east-to-west manner while Runway
16-34 is oriented in a north-south
manner. For the operational safety
and efficiency of an airport, it is desirable
for the primary runway to be
oriented as closely as possible to the
direction of the prevailing wind. This
reduces the impact of wind flowing
perpendicular to the direction of travel
of an aircraft that is landing or taking
off (defined as a crosswind).
FAA Advisory Circular 150/5300-13,
Airport Design, Change 11, recommends
that a crosswind runway

All-weather wind data specific to Riverside
Airport was obtained from National
Oceanic and Atmospheric Administration
(NOAA) for the years
from 1997 to 2006. The wind data is
depicted on Exhibit 3E. Runway 9-27
provides 96.15 percent wind coverage
for 10.5 knot crosswinds and 97.16
percent coverage at 13 knots. Runway
16-34 provides 94.45 percent wind
coverage at 10.5 knots and 97.04 percent
coverage at 13 knots.
The two-runway system at Riverside
Airport provides 99.55 percent coverage
for 10.5 knot crosswinds and nearly
100 percent coverage for other
crosswind components. There is no
need to consider additional runway
orientations at Riverside Airport.
