The invention relates to a data transfer method in a digital cellular radio network, the method comprising channel coding the information to be transferred for transmission. The display device includes a processing unit configured to receive arrestor bed information associated with a runway and to generate display commands based on the arrestor bed information; and a display device coupled the processing unit and configured to receive the display commands and to display symbology representing the arrestor bed information. The friction pad is connected to the coupling portion between the first end and the second end. Electrical connectors are positioned within the access openings and configured to provide electrical coupling to the cable and to an external device. The crank is coupled to a second control member which is threaded along a distal portion.
