Aircraft compression relief rod

A method of operating an aircraft, comprising:

• positioning a truss support structure in the aircraft, wherein the truss support structure comprises:
• an upper support rail;
• a lower support rail;
• at least two vertical tie rods connecting the upper support rail and the lower support rail;
• a diagonal tie rod, wherein a first end of the diagonal tie rod is connected to the lower support rail proximal to the connection of a first vertical tie rod of the at least two vertical tie rods with the lower support rail, and wherein a second end of the diagonal tie rod extends away from the first vertical tie rod and is connected to the upper support rail;
• and a tension-only member, including:
• a first connector end;
• a second connector end;
• and a tension-only connector arranged between the first and second connector ends, wherein the tension-only member is arranged between the first vertical tie rod and a second vertical tie rod of the at least two vertical tie rods, wherein the first connector end of the tension-only member is connected to the lower support rail proximal to the connection of the second vertical tie rod with the lower support rail, and wherein the second connector end of the tension-only member extends away from the second vertical tie rod and is connected to the upper support rail between to the connection of the first and second vertical tie rods with the upper support rail;
• and operating the aircraft, wherein operating the aircraft comprises:
• accelerating the aircraft and exerting a first load in an aft direction of the aircraft during the acceleration, the diagonal tie rod supporting the first load during the acceleration;
• and decelerating the aircraft, the decelerating exerting a second load in a direction of the flight deck of the aircraft, the diagonal tie rod and the tension-only connector supporting the second load during the decelerating.
