OK...here we go again...my flight ops tell me that on 737-800 all our divert scenarios are based on LCR with 1185NM 180 ETOPS. To me this does not seem realistic. Where am I going wrong here.
My understanding is the circles are depended on the divert speed .
Obviously with LRC the speed varies with wight and how many engines are turning.
We are told to fly the FMC at all times.
