In the Vulcan B2, steering signals were presented to the pilots by azimuth director pointers on the MFS director horizon. You banked the aircraft to put the circular bank indicator over the ADP and kept it there, achieving the required steer when the wings had levelled.
The steering source depended upon the MFS selector panel (which had a 'bomb' position for the NBS steering signal) and the MFS / HRS switch. Beam compass heading demands were presented to the ADPs with 'MFS' and 'central' selected on the MFS selector, 'HRS' steers were generated by the Nav Plotter and displayed to the ADPs with 'HRS' and 'central' selected.
"Go to 'bomb', advise demand!" - I can still hear that today!
