I believe TERPS uses 25 degrees AOB whilst PAN-OPS uses 20.
For 757 (for us)
Establish on IAP Gr Dn flap 20 (if ILS remember not to arm App). On reaching circling alt in alt hold set MAP alt. When visual break off 45 degrees for 45 secs (can do 80/80). Downwind, abeam the threshold fly for 3secs/100' (we use +/- 1sec/1kt H/T). Start base with gradual descent (3-400'/min). Flap 30.
MAP to be flown is the one associated with the initial IAP flown.
