As a result of the above findings, the runway length calculation from the FAA program for small aircraft
was checked against the runway requirements for the Airport’s family of critical aircraft (ARC C-II), to
determine if special circumstances would require additional runway length. C-II aircraft are those aircraft
with approach speeds of 121 knots or more, but less than 141 knots and wingspans 79 feet or more, but
less than 118 feet.
