T-22 has two major improvements for easier scanning and viewing while retaining all of the bar an spacing in the traditional USAF 1951 chart; meeting the requirements as specified in MIL-STD-150A. The layout has been reconfigured from the spiral layout to two straight columns while the Group & Element reference labeling has been changed to the DIRECT frequency Labeling in C/MM adjacent to their features. The numeric labeling is enhanced and based on OCR-A extended font, to maximize recognizably. Smaller Elements have finder squares next to them to aid in determining their locations.
