Wiggy:
During my early years on the 727 we had a real turn and bank indicator. That big ball was great for OEI. Then, the FAA deleted the requirement to have that real T&B, so the company removed them. The little ball below the FD-108 attitude indicator was useless, so we had to get used to using the control will to achieve the proper rudder input. That took a bit of getting used to.
