W D CORNELIUS RANCH
MARKHAM, TX
Markham's W D Cornelius Ranch, identified as XS07, is a privately owned, non-towered airport. The airport provides a single turf runway, 13/31, which measures 2,100 feet long and 100 feet wide.
Operations are visual flight rules only because no instrument approach procedures have been published. The strip is non-towered with no published frequencies, so pilots keep their own separation under see-and-avoid procedures. There is no fuel service listed for the field. As a private-use facility, it is not open to transient traffic without prior permission.
The field rests at 47 feet above mean sea level.
