4.02-2 Runway Orientation
The orientation of runways for takeoff and landing operations is primarily a function
of wind velocity and direction, together with the ability of aircraft to operate under
adverse conditions. As a general rule, the primary runway at an airport is oriented as
closely as practicable in the direction of the prevailing winds. The most desirable
runway configuration will provide the largest wind coverage for a given maximum
crosswind component. The crosswind component is the vector of wind velocity and
direction which acts at a right angle to the runway. Further, runway wind coverage is
that percent of time in which operations can safely occur because of acceptable
crosswind components. The desirable wind coverage criterion for a runway system
has been set by the FAA at 95 percent for any aircraft forecasted to use the Airport on
a regular basis.
All-weather, VFR, and IFR wind roses were developed for Potsdam Municipal
Airport using information gathered from the weather observations taken over a 10-
year period from 1997 to 2006 at Massena International Airport. As shown on the
wind roses depicted on Figure 4-1, Runway 6-24 provides an all-weather wind
coverage of 99.83% for a 16 knot crosswind, 98.93% for a 13 knot crosswind, and
97.28% for a 10.5 knot crosswind. The figures exceed the FAA's recommended 95%
wind coverage and provide acceptable coverage for the smallest aircraft 97.28% of
the time.
