at least one second fitting element mounted at a distance of between 163 and 175 cm from the center plane; and/or

at least one third fitting element mounted at a distance of between 225 and 240 cm from the center plane; and/or

at least one fourth fitting element mounted at a distance of between 260 and 280 cm from the center plane.

6 . The cargo deck according to claim 5 , further comprising a pair of fourth perforated rails, wherein the third and fourth fitting elements are arranged alternately to one of the fourth perforated rails, wherein at least one side guide is fixed to each of the pair of fitting elements and to the fourth perforated rail.

7 . The cargo deck according to claim 5 , wherein:

in at least one segment, a pair of first, second, third and fourth roller tracks are each arranged symmetrically with respect to the center plane; and/or

in at least one segment, a pair of first, second, third and fourth perforated rails are each arranged symmetrically with respect to the center plane; and/or

in at least one segment, a pair of first or second or third or fourth fitting elements are each arranged symmetrically with respect to the center plane.

8 . The cargo deck according to claim 1 , wherein the center guide locks are each anchored in two first perforated rails.

9 . The cargo deck according to claim 1 , wherein the center guide locks are formed and arranged or arrangeable at least in one segment in such a way that the stop surfaces of the side guide claws in one configuration and/or arrangement delimit a center aisle, wherein the stop surfaces of the side guide claws in this configuration or arrangement are spaced at least 15 cm from the center plane.

10 . The cargo deck according to claim 1 , wherein at least one of the center guide locks comprises a center guide claw having two alternating stop surfaces, wherein a stop surface of the side guide claw in an erected position is oriented in an opposite direction to a stop surface of the securing claw.

11 . An aircraft having a cargo deck according to claim 1 .

12 . The cargo deck according to claim 1 , wherein each of the first and second center guide locks further comprises:

a center guide claw mounted in the frame and having a first stop surface and a second stop surface which are aligned in opposite directions and are spaced apart;

wherein the stop surfaces of the side guide claws and stop surfaces of the securing claws are spaced apart from each other in an erected position by at least 30 cm and are oriented in opposite directions.

13 . The center guide lock according to claim 12 , wherein the center guide claw is arranged in such a way that in an erected position the stop surface of the securing claw is spaced from the first stop surface of the center guide claw by a first distance, the stop surface of the side guide claw is spaced from the second stop surface of the center guide claw by a second distance, and the first and second distances are the same.
