At noon local time (1700-1800Z), Lincoln's Class C airspace is in effect (service 1130-0600Z).

An aircraft west of the field lies in the 180-359 degree sector, whose approach frequency is 124.0 MHz. The tower is contacted later, when approach hands you off. Minneapolis Center is not the facility that serves this Class C airspace.
